China, India battle for aerospace lead

Your "hot air" statements and twisting comments out of context just indicates that you have no idea about the history of either LCA or the J-10.

Hot air!! where? oh dear..... could you tell us here the aerospace power of India please .....we are not interested in History.....of 30 years and still more to come of Lost Aircraft.
Please point out to me where I said that Lavi design belongs to the Russians. And yes it does not belong to the Chinese either.

You are authoritatively claiming J-10 as Levi design, could you care to point me in that direction, not the BS it is "claimed" or rumered thing.... facts either from Chengdu or Israel.
May be you educate yourself first,then we will talk. Shall we. Else you are just making a fool out of yourself.

Another Boiler plate from the loser..........I need to educate!!!:victory: World know who is making a bafoon of themselves.... the fanboys who acts as all knowing.... when even airforce does not want the piece of crap.


I suggest the fanboys who are wetting themselves in delusion and self deception......that they hold thair bragging until some semblence of aircraft come out..... rather than relying on so-called research paper.

Stop these stupid threads of...... battling it out for aerospace lead:blah: :blah:
 
.
Oh I see !!!! so this Lost Chance Aircraft (LCA) should be on par with Typhoon... tell me you are kidding.:P

With the design given on platter and on top "Consultancy" provided by BAE, Dassault and Otheres whats you got ? nada zilch.... moreover america opened its laborateries still nil.

With these accomplishment you want to battle it out with China in aerospace?:bunny:

If the Indians had got everything on a platter, they wouldnt have visited the windtunnel a few thousand times. Nor would the project have taken the time its taken. Fairs fair. I believe that this is a Pakistani forum, so some amount of Indian baiting and vice versa is inevitable, but the LCA is indeed more Indian than the Gripen is Swedish or the Ching Kuo Taiwanese or the F-2 Japanese. In the first, BAe played a huge role, and the import content is far more than the Indians are going for. The other two were practically designs handed over to the respective countries by consortium partners. Once the LCA is inducted, India will be one of the few Asian countries able to field a fighter of its provenance. Recognising this is but sensible.

Secondly, I do think the PRC has a lead on India in aerospace, but its not a massive one. Reason being that the PRC is locked out of proper cooperation with western and israeli firms. Importing technology, subsystems and reverse engineering to putting in funds alone isnt enough. In recent years, with Indian economic growth, Indian Defense R&D budgets have shown a spike towards reasonable expenditure- if the current trend continues, its not unreasonable to expect that the Indian aerospace industry will have a fillip.

Most importantly, the recent 30% offset rule will help Indias industry by leaps and bounds. 30% of a 10 Billion$ MRCA contract is 3Billion$ reinvested into India. And India appears to have many more plans apart from the MRCA alone.

Well considering the topic of the thread that was a balanced and non inflamatory post so kudos.....

Anyway It would be foolish to think that the Chinese would not be able to build from their huge base that has successfully churned out a vast number of aircraft. I am sure some wit will leap in with some comment about how they "copy" stuff:blah: but they have a huge budget....good education system and whole generations of successful aircraft which have important improvements.

Who said they visited the windtunnel in vain? You have the output of those visits through the mountain of research papers and 100's of paper doctrotes.

see you are now talking sense, if your comrade in arms were so sensible in accepting LCA is no better than F-2 OR IDF this would not have been the pissing contest. The insistence on "Indeginous" -the much abused and raped word in LCA is what needs to be corrected.

Please do not give a new name to JF-17 =J-9 it is officially FC-1 in china, FC-1 and JF-17 is more than it can handle to avoid confusion.

Well when it goes into production for China it will be given a J-number (9 in all likelihood) As I am sure you know the J means something in Chinese. Do you know what it is?
The only aircraft that get a "F" prefix are ones that are independently funded rather than government funded. When the Fc-1 goes into service then it will drop that code and become a J number.
If others are confused that is their problem not mine, as it is fairly simple.

I did realised I entered in talk with someone in denail in the first place. I wonder if the other gent who is thumping his chest of defining what is indigenous even knows that there is TEXAS INSTRUMENTS written all over RBE 2 of Rafale.

Didnt quite get you, what you mean because I said the exact line he said in different structure, the insistence on the definition of indigenous that you know of is only applicapble where you can triumph your points of view over logic obviously in selected forums, surely there are very senior members here like Muradk et al who unlike you was actually in service, ever felt why your point of view wont stand in international forums? or why are not these senior members backing your POV? food for thought eh? surely the definition of indigenous needs to be corrected in your own dictionary when you will handle a project of this scale, if ever you do.

You should also go in some other dozen forums and correct peoples of these terms,

Chinese J10
Swedish Gripen
Japanese F2
French RBE 2
etc etc I can go on.

They should also be a misnomer to you unless your dictionary has double standards which is obvious.

You are not aware of the other HF series of birds that was prototypes build but never entered service, the scientists literally ran to indraprastha for funds but alas the great soviet support was needed and flow of cash to their defence industry was needed as well. I'll post regarding them.

Before saying anything I hope I did said in my post to you that the report posted in first page has indeed many factual mistakes, and Chinese industry is ahead, I also gave you the main reason behind it from a notable scientist of IISC who analysed the aerospace present and future of India, Aerospace sector is ENTIRELY dependent upon the states will to pursue things aggresively, capabilities comes second which is dependent on the manpower available and experience the very first thing is what we lack, just was the case after Marut other designes were freezed the aeronautics sector came into dead stop. What do you think will happen if there comes no funding for MCA? Yes it will die in the lab.

First of all dont discount the upgrades of bird as merely upgrades, they takes a lots of balls to do without OEM support, the Mig 27 upgrade is one such upgrade which uses modern mil STD 1533B bus and retains the soviet era PPRV type switching mechanism.

Then there was the Jaguar DARIN II upgrade , the Mig 21 upgrade and the Mig 23 upgrade.

Now coming back to the MKI project, lets just consider the BARS N011M radar system a good set of data I'll post here,

----------------------------------------
RSLU-30MKI (the name of the whole weapons complex around N-011M Bars) is constituted of mixed equipment, Russian and Indian. No one doubts that here ok?

Indian equipment is related to Radar Data processor (RC1/RC2) and the software it runs. The functions of those processors are intimate to the functions of the radar, it doens't only controls PRF or target tracking, it controls whole weapons employment (per example it controls the kinematic launch dinamic range zones for all missiles, and it contains the software asociated to such missiles and bombs) it also works with some physical properties of the radar (so that it controls the beamforming system that allows simultaneous air/air and air/ground weapons modes).

If you get out those RC1/RC2 you have to get back and try the whole thing from scratch...RLSU-30MKI was an improved (and finished) version of the complex that formed N-011M with some russian gadget...those gadgets (Ts100 series RDP) were not finished in software and logic implementation (that's why Su-30MKI mk1 that used those pieces of equipment is limited compared to Mk3 that have the indian stuff).

In the year 1992, and it was time for Farnborough, the first Su-27M with the N-011 radar (703, in fact the first new build prototype) was just starting to fly. Only 20 N-011 sets were built at NIIP (Tikhomirov, no Phazotron, althrough in the 70s, both NIIR and NIIP were part of NKO Fazotron, they separeted later), and the first radar was just in test. By those times too, the first (very first) prototype of the improved phase array N-011M was built...it was not tested till 1996, with T-10M-12, the 12th prototype of Su-27M (Su-35 for export in those times)

N-011M is not exactly Bars, because N-011M R&D was never finished in the original path the russians wanted or tried, and was India under the Su-30MKI deal, that give the money and better technology to NIIP and GRPZ (the factory) to finish the product, and to introduce a series of indian-desired changes. Please bear in mind, the following things:

a) In 1988 it was decided that the radar for Su-27M would be of phase array kind. By those times, other alloted changes for Su-27M program (T-10M inside bureau) was TVC and improved engine (contrary to most published BS info in the 90s, Su-27M prototypes, never fly with the improved engine, sans T-10M-11 or Bort 711, the "Su-37"). The N-011 program was started years back, it would use technology first envisioned for the original "Myech" N-001 radar used on Su-27S (FLANKER-B ASCC) that the soviets in those times, could not handle at industrial level...other changes come from NPO Istok's "SOYUZ" program, that was the development of radar technology from various sources (mostly oriented towards semiconductor technology applied to radar and that kind of things), and some of those "sources of knowlodgement" were from espionage and intelligence. AN/APG-65 data was used for developing "SOYUZ".

So you can see:

N-011 = first envisioned Su-27M radar = Original Myech technology + Soyuz developed technology + at the time advances + new doctrine specifications (new role that Su-27M would play in VVS Frontal Aviation Fighter Aviation Branch). Never finished

N-011M = revised specs for Su-27M radar from 1988 that envisioned phase array use over earlier N-011 iteration + advances made by NIIP on other programs (N-014). Never finished

Bars = finished product (N-011M) with heavy Indian collaboration and funding. Product finished

------------------------------------------------------

So you can see these are definite heavy duty works and it would be silly to think software developement for PESA is very simple. India gained good experience handling a state-of-the-art PESA, while there was good funding behind the whole endeavour so manpower was never worrysome factor in the game. And you have todays latest AESA's which are ENTIRELY software controlled, the better radar engineer/soft ware expertise you have better maturity of AESA and ofcourse reliability of TR modules but can be taken care of with a good FAB facility, but all this takes huge and huge funding.

HF-73 AND MBB
The report on the Indian combat aircraft project Hf-73 and the appropriate contacts between Hindustan aircraft Industries and Messerschmitt Boelkow Blohm, published in FR 11/75, strikes still waves. In the 19. Meeting of the German Bundestag, on Friday, 18 March 1977 answered the parliamentary undersecretary of state Dr. von Buelow an inquiry of the SPD delegate Hansen, which had read as follows:

"does it apply the fact that the company Messerschmitt Boelkow Messerschmitt-Boelkow-Blohm contributed to the Indian airplane project Hf-73 as much MRCA Know how that the only difference to the MRCA exists in the rigid wing of the Hf-73 and if, as agrees upon itself this fact on the one hand with the secrecy need and on the other hand with the stated will of the Federal Government to permit no loosening or evasion of the export restrictions?"

The answer of the defense undersecretary of state read as follows:

" 1. Cooperation of the company MBB in the context of the Indian airplane project Hf-73.

During the activity of Professor Tank with the Hindustan aircraft (India) in the 60's the combat aircraft Hf-24. developed since 1971/72 is Professor Tank coworker of the company MBB. From this situation company MBB received an order for an appraisal in the year 1973 from the Hindustan aircraft over the advancement of the Hf-24 using the engine Rb-199 (in development at that time for the MRCA). This appraisal was provided by an MBB team 1973 on the occasion of a 3-4-woechigen of India stay, whereby the project suggestion Hf-24 MK III or also in the following developed for Hf-73 mentioned. Afterwards only small activities followed on the part of company MBB, until it came 1975 to the abort of the work on this project, since the Federal Republic of Germany forbade a use of the engine Rb-199 for other projects except MRCA.

2. Differences between the airplanes Hf-73 and MRCA.

The Hf-72 differs in the following substantial points from the MRCA:
* Single-seater (?)
* Double tail unit
* No tiltable wings, completely different wing and tail unit sketch
* Max. weight 10 t in relation to 18 t MRCA
* No all-weather combat ability it is present thus an entirely different conception of both airplanes.

Easy geometrical similarity exists only in the range of the engine intakes. This similarity arises inevitably as a result of the installation of the same engines.

3. Secrecy regulations.

No information is present that the company MBB offended to it against in the framework MRCA the imposed safety regulations in any way.

In chapter 2 the fundamentally different conception of both projects is pointed out, i.e. that already from the thing no necessity existed to bring safety-relevant MRCA data directly into the project Hf-73. Further in the year 1975 the abort of the work on the project Hf-73, taken place, offers an additional security, since the development of the MRCA in the meantime continued to progress.

4. Export restriction.

Company MBB had contacts with the Indian airplane company, which rest since 1975 after available level of knowledge completely until 1973 only in the context of an appraisal. An expansion of the activities on the part of MBB, which could have contained a loosening or an evasion of the export restriction, did not take place after available information not."

Alright here's more info. The Marut version which entered service was the Mk.1. The Marut Mk.II was supposed to have been supersonic, powered by afterburning Orpheus 703s or E300s. The HF-73 emerged as the Marut Mk.III and was'nt quite the same aircraft. As a derivative, it was designed to have maximum hardware commonality with the Marut, for service entry in 1981-82. The aircraft was to be powered by Rolls Royce RB.199 afterburning turbofans, with a speed of Mach 2.0+.

There are tons of obscure HAL projects that never entered service due to buying cheap soviet fighters,

HT-10 - Advanced prop trainer similar to Harvard/Skyraider with side by side seating. Armed with rockets.

HT-11 - Basic trainer similar to above.

HJT-17 - Parallel development with Kiran as a possible alternative. Mockup/Prototype built.

HTT-35 - Similar to Tucano but with shorter aft-fuselage and raised rear seat.
A mockup painted in gloss red was on display in one of the earlier
Bangalore Airshows. There's a pic of this in the "Encyclopedia of all
the world's aircraft" or something similar.

HCP-25 - Small utility transport aircraft. Prototypes built.

HAC-33 - Military transport with the ability to carry 24 troops/12 streachers
in a pressurised cabin (20 seat capacity). Design began in Dec.
1973. The Do-228 took it's intended role.

India's first indigenous engine was'nt the Kaveri either. The HJE-2500 turbojet was built for the Kiran and tested in 1966

HAL HTT-35


HTT-35 is designed to meet the IAF Air Staff Target 208. This details a replacement for both HPT-32 and HJT-16, inferring a requirement for more than 150 aircraft.

Unveiled in mockup form at Avia India 93 (Dec 1993), the HTT-35 is a conventional looking tandem seat low-wing monoplane, with a distinctively hump backed appearance and stepped cockpit covered by separate upward hinging canopies. The retractable tri-cycle undercarriage retracts inwards (main units) and rearwards (nose gear). The pilots will sit on lightweight ejection seats.

HAL hopes to use either the 1150 SHP Garrett TPE-331-12D (flat rated to 11 SHP / 819 KW) or the 1150 SHP P&W Canada PT6A-62 (flat rated to 950 SHP / 707 KW) to power the new aircraft.

Full scale development awaits a government nod, which HAL hopes to receive by Mid-94, leading to the first flight 24 months later.

Performance:

HAL claims a maximum level speed of 290 mph (470 kmph) at Sea Level with a stall speed in approach configuration of 80 mph (127 kmph).

The Take-Off to 50 ft (15 m) is 850 ft (260 m) and landing distance from 50 ft is 1900 ft (580 m). The sea level rate of climb is calculated as 4000 ft (1220 m) per minute, and service ceiling as 29,500 ft (9000 m).

The HTT-35 will be fully aerobatic, with a normal operating load factor of +6 to –3.8 and a fatigue life of 7000 flying hrs.

Weights:

The integral wing and fuselage tanks will carry 450 kg of fuel, with an inverted system allowing upto 30 s inverted flight. This gives a range of 790 miles (1270 km) and allows two high-density aerobatic/spinning sorties to be flown on a single load of fuel.

Underwing hardpoints (stressed for loads of up to 250 kg each allow the carriage of bombs, gun or rocket pods for weapons training of CI duty.









The abover is as per the translated article.

Another article on India's aviation history, etc from aeroindianews.com

On 17 December 2003, the world celebrated the hundredth anniversary of man's first powered flight. Momentous advances have been made in aviation and what marks these developments is the will to succeed and explore new frontiers of knowledge and so achieve those historical milestones.

India's first efforts in aeronautics were started more than six decades ago by Walchand Hirachand and the then Mysore Government. The aircraft company started by them was taken over by the Government during the Second World War to initially function as a repair base depot for South East Asia Command. Thus was established what is now Hindustan Aeronautics Limited (HAL). Sixty years on is not a small period of time to take stock of the progress in aeronautics in the country. For anyone who has been associated over the years with aeronautics at policy levels, the question that frequently arises in one's mind is the extent of commitment to obtain a measure of self reliance in this important field of advanced science and high technology.




The legendary Dr. Ing. Kurt Tank spent over a decade with HAL

The aircraft industry is characterised by long gestation periods, with development of appropriate technologies demanding a long term vision. It is the lack of such clear policy that has hurt the development and growth of indigenous aircraft programmes. Dr.Kota Harinarayana, former LCA Programme Director has in a recent lecture drawn attention to the "need for pro-active designing". He stated "Quality parameters would have to be incorporated at the design stage of aircraft-building instead of attempting corrections at the testing and manufacturing levels". The fact of the matter is that if quality parameters have to be incorporated at the design stage itself, forward technology development in anticipation of future requirements is essential.

It is this vision that has been lacking in a healthy growth of the Indian aircraft industry. The Light Combat Aircraft (LCA) development programme has shown how serious the situation could become without such a vision. An overview of the growth of our aircraft industry indicates that we did not pay adequate attention to creating self reliance by building a strong research and technology base, but instead depended over the years more and more on licenced production. It would be instructive to recall our past acts of commission - and omission - if only to learn from these.

It was around 1967 that Vikram Sarabhai, the visionary space scientist, visited the Belur campus of the National Aeronautical Laboratories (NAL). Looking across the runway towards HAL, he expressed his ambition to put an Indian-made satellite into orbit with an Indian-made launch vehicle, before the next generation Indian-made fighter aircraft would take to the skies. His ambition was subsequently achieved by Satish Dhawan, his successor, with APJ Abdul Kalam as the Project - Director for the SLV-3 programme. It is important to note that in Space matters, R&D, the launch vehicle and satellite development were vertically integrated and the Department headed by scientists and technologists who were technically familiar with their respective fields. Their successes, and those in atomic energy, conclusively demonstrated that given the political will, and professional leadership, we could achieve successes in developing technologically sophisticated hardware in aeronautics as well.

In the mid-fifties, under leadership of the German designer Dr.Kurt Tank, India launched development of the HF-24 supersonic fighter aircraft. Regrettably the Government of the time was unwilling to sanction Rs 5 crores to Bristol Siddeley for development of the afterburning follow-on engine to the Orpheus 703 as its power plant. The HF-24 could not achieve its designed performance without this, a serious error in policy, causing serious setback to the fighter's development and for that matter, the future of developing a substantially self reliant aircraft industry. In this situation, the Air Force continued to buy outright or take up licenced production (through HAL) of aircraft needed by them. Development of the HF-24 also underlined the importance of developing own engines as an essential precursor for fighter aircraft development.

One of the consequences of the HF-24 development programme was the belated awareness that if we did not have a strong R&D base, it would not be possible to achieve any self-reliance. This awareness resulted, during the late '50s in creation of the Aeronautical Development Establishment (ADE) and the Gas Turbine Research Establishment (GTRE) under the Defence Research and Development Organisation (DR&DO), as also the National Aeronautical Laboratories (NAL) under the Council of Scientific and Industrial Research (CSIR), being the R&D organisations to back aircraft development activities in HAL. While development of the HF-24 was proceeding under Kurt Tank, HAL took On the concurrent responsibility for design, development and series production of the jet trainer HJT- 16 Kiran. This was the first major attempt made by HAL to design and develop a jet aircraft on its own without any foreign assistance in its design. Then OSD and later Managing Director for Design & Development at HAL, was Raj Mahindra who played a significant role in the Kiran 's development.

During those days ADE was mostly concerned with development of hovercraft, pilot less target aircraft (PTA), remotely piloted vehicles, simulators etc. It was only when the Light Combat Aircraft (LCA) programme was taken up in the 1980s and responsibility for developing the "fly-by-wire'' (FBW) control system for the LCA was given them, their interaction with HAL really began.

The first major task that GTRE took up, with specific end objective was development of an afterburner for the Orpheus 703 engine for the HF-24, after the Government had rejected the earlier Bristol Siddeley proposal. GTRE was able to demonstrate (on the test bed), the desired 20% increase in thrust in the reheat mode and also concurrently took up development of the various major subsystems such as the compressor, the
combustion chamber and the turbine stage that go into making a 5000 kg-class flat-rated gas turbine. This knowledge eventually helped GTRE in prototype development of the experimental GTX-35 gas turbine.




India's first home-designed produced fighter: the HAL HF-24 MK.1 Marut

The need for generating crucial high speed wind tunnel data for the HF-24 on our own, highlighted the importance of having such facilities within the country. Satish Dhawan, then at IISc and V.M.Ghatage, then with HAL's Design Bureau, were the driving forces for establishing the Wind Tunnel Centre which became core of NAL activities. Homi J.Bhabha, Chairman of the Atomic Energy Commission was instrumental in prevailing upon Prime Minister Nehru to establish the NAL within CSIR, a civilian organisation, hopefully to obtain better interaction with other countries. The UNDP thus helped NAL with a grant to build the infrastructure and start research activities, primarily intended to support airframe development in HAL. NAL latter collaborated with the Space Department in development of their launch vehicles and also took up, as in-house activity, forward looking basic and applied research, with some technology development in certain critical areas, which is the key to self reliance.

By the late 1960s, the Kiran jet trainer went into series production but the matter of any future fighter aircraft development in the country remained in a state of suspended animation. It was against this background and substantial dependence on licensed production, that Prime Minister Indira Gandhi appointed C.subramanyam, former Cabinet Minister, as Chairman of an Aeronautics Committee to examine the situation, its study group for R&D having clear instructions from the Chairman to recognise the problems and take appropriate decisions.

An aspect looked into by this Committee was to ascertain as to what had wrong when the afterburner developed by GTRE was installed in the HF-24. It was quite apparent that adequate attention had not been paid in redesigning aft-end of the HF-24 in accommodating the afterburner. The 20% increase in thrust demonstrated on the test bed was washed out owing to an increase in fuselage drag.

An important recommendation of the Aeronautics Committee was creation of the Aeronautics Research and Development Board (AR&DB) as the focal point for supporting forward looking R&D, so as to support future aircraft development. C.subramanyam took up the matter directly with the Prime Minister as such an establishment was considered vital for establishing a firm indigenous aeronautical base. If enough attention was not paid to develop necessary technologies through futuristic R&D, aircraft development programmes would be delayed, or subjected to sanctions by other countries, as eventually happened in the HF-24 programme.

Unfortunately after its creation, the AR&DB functioned on an ad hoc basis, without any long term R&D policy of its own. Furthermore, the funds made available to it were pathetic, considering the scope of responsibilities. Shortly after its creation in the 1970s, a proposal was made to then Scientific Advisor to the Minister of Defence and Chairman AR&DB, that this should become the focal point. With a particular DR&DO laboratory not agreeing, integrated planning for R&D and centralised support for it remained on hold till the LCA programme came along a decade later.




The HAL HJT-16 Kiran Mk.1

The Aeronautics Committee had recommended development of light fighter aircraft, light transport aircraft and light helicopters. The helicopter programme was launched with Raj Mahindra initially heading this. HAL continued to carry out feasibility studies of the several Air Staff Requirements (ASR) being projected from time to time, with the hope of eventually launching a fighter aircraft development programme. The ACA, GAF I and GAF II, were the subject of feasibility studies. Considering latent potential of the HF-24, HAL also tried to obtain the Rolls Royce RB- 199 as the power plant for a new variant (the HF-73). It was however widely felt that the HF-24 with RB-199s, would upset plans for what was planned: licence production of the Jaguar in India. The Indian Air Force thus continued to buy aircraft outright, or get those required by them to be produced under licence by HAL.

Development of a transport aircraft, primarily in response to civil requirements, did not come through and so HAL only produced the Avro 748 and later, the Dornier 228 under licence. A far reaching proposal by Dornier to HAL for the joint development and production of new generation regional airliners did not get support. Subsequently Dornier went into collaboration with a US company and India missed a key opportunity to enter the global arena.

Owing to the limited Indian market and difficulties in penetrating international markets on one's own, commercial aircraft development has just not been a priority for HAL. In recent times, to control its destiny to some extent, NAL took upon itself the responsibility of developing the Glass Fibre Reinforced Plastic (GFRP) two seat trainer aircraft Hansa, and the 14-passenger multi role Saras. The Hansa has been type-certified and a few of them produced by NAL for flying clubs. Its eventual series production will have to be based on its commercial viability. The Saras was conceived as a Rs 130 crore project and the prototype has recently flown. It would appear that its development as a successful commercial aircraft demands significant weight reduction, which may even call for redesign of its structure to make it commercially viable and which may result in delay of its eventual type certification and cost over runs, thus impacting on its commercial future.

Coordination among the aeronautical institutions in planning their R&D has continued to be negligible. Until Dr.Krishnadas Nair came on the scene as Chairman of HAL, corporate R&D work in HAL was not significant. Elsewhere in the world, corporate R&D plays a crucial role as an interface with other R&D and academic institutions, to absorb such knowledge and use it in tangible development of aircraft.

In this context, it would be interesting to look at the American scene. Faculties from academic institutions are frequently used as consultants by the US aircraft industry. Problems posed by the industry then become assignments for technical students. The more complex ones are submitted to NASA or the US Air Force for project specific support, which frequently results in PhD theses, with the results eventually becoming inputs to the industry, thus closing the cycle of specific knowledge generation and its utilisation by the industry. For example, when the US Air Force desired to increase the turbine entry temperature of jet engines to obtain higher operational efficiencies, it supported several programmes in academic and research institutions as also the industry running into millions of dollars. When such cooled turbine blade technology was successfully developed, it superceded all ongoing programmes.

Recognising the lack of progress in self reliance, Prime Minister Indira Gandhi constituted an Aerospace Group in 1976 under Chairmanship of the then Scientific Advisor. It was a high level committee which deliberated for about two years but could not come to any conclusions that would further the cause of self reliance. There was inherent conflict in perceptions of the scientists and the civil servants placed on the committee. The scientists argued that it would be impossible to obtain any self reliance without close coordination between industry and the R&D, and that these should be integrated along lines of the Space Commission to evolve appropriate policies, programmes and procedures. If this had been agreed upon, a technocrat might well have headed the new agency as was the case with Space, something the civil servants were implicitly unwilling to agree upon. After extended discussions, the civil servants recognised the need for some integration and reluctantly agreed for achieving this through a form of "evolution", but were not willing to set a time dead line (as they felt that it would weaken their authority?). As it subsequently turned out, even the Scientific Advisor, who had little understanding of the complexity of aeronautics, was unwilling. It became quite clear that it would be easier to create a new department of the Government than restructure existing ones.

Dr.Raja Ramanna took over as the S.A. around 1978. He felt that achieving some manner of self reliance was still not a lost cause and that it could perhaps be achieved through a tangible fighter aircraft development programme - if the Indian Air Force would support it. It was indicated to the then Air Chief that if the Air Force did not want an indigenously developed aircraft, the relevant research laboratories might as well diversify and take up other (non-aviation) activities. However if the Air Force believed in a measure of self reliance, then that was the time to support an indigenous fighter aircraft development programme. The ability of the Air Force to protect Indian skies would not be compromised, as the MiG-21 aircraft was still under licenced production and the Jaguar was also contracted for. The Air Chief gave his full support. The aeronautical community owes much to Air Chief Marshal Idris Latif for this. This most important hurdle was crossed and a major breakthrough was achieved 25 years after launch of the HF-24 programme.

The Scientific Advisor wisely suggested that some European aircraft industries be retained as consultants, to come up with their own feasibility studies of the Air Staff Target. Simultaneously an integrated Indian design team was constituted comprising personnel from HAL's Design Bureau and the R&D and academic institutions, the first time that such an integrated team was constituted. Thus was born the Light Combat Aircraft (LCA) development programme.



The way it was: HAL design engineers at their drawing boards

Results of those diverse feasibility studies submitted by the French, German and British aviation industries were most revealing. It was clear that our designers were in no manner inferior in conceptual design, but we did not possess some of the crucial technologies needed for the new generation LCA. The carbon fibre composites (CFC) technology for the airframe and the "fly-by-wire" (FBW) control systems, with relaxed static stability were found to be critical for the LCA's development. CFC technology development had received steady support over the years in NAL and did not therefore pose serious problems. FBW technology was a different matter. Attention had not been paid on its development earlier neither on any detailed studies of the problems posed by relaxed static stability design.

Noting that in 1981 British Aerospace had converted a Jaguar as its flying test bed to study relaxed static stability and FBW problems, it was proposed to the HAL Board of Directors that an HF-24 be converted into such a flying test bed to study such aspects, as these technologies would be essential in responding to future needs of the Air Force. Forward technology development to respond to potential future needs is a vital characteristic of the aircraft industry. But, the proposal was rejected by a civil servant from the Defence Ministry (who was on the HAL Board), stating that if the Government did not eventually sanction an aircraft development programme, the test bed would be considered as "in fructuous expenditure!" In spite of such negative reactions, a project was jointly proposed by HAL and NAL, well before the LCA development itself was launched, but this did not receive tangible support.

The LCA programme was formally sanctioned by the Government in July 1983, following which the Aeronautical Development Agency (ADA) came into existence, with Scientific Advisor to the Defence Minister as Chairman of its Governing Body. A Director General ADA was to be appointed as its chief executive to fund, manage and monitor the programme. At that time it was clearly understood that the ADA would be a lean organisation, which could, if necessary, be wound-up at short notice. It was agreed that the primary responsibility for design and development of the LCA would be vested with HAL with various other agencies functioning on a subcontractor mode under the auspices of ADA. However, soon enough, functioning of the ADA changed dramatically with this body taking on major design responsibility for development of the LCA by itself!

The principal architect in the initial phases for conceptual design of the LCA was Raj Mahindra. ADE was given responsibility for the FBW technology development by ADA, which in turn gave a back-to-back contract to a US company for its development. The General Electric GE F.404 was chosen as the initial power plant. The Kaveri engine (currently under development by GTRE), was not even on the drawing board at that time. The GTX- 37 engine under development was found unsuitable and could not achieve the performance required. NAL interacted closely with HAL in airframe development of the LCA, taking major responsibility for its carbon fibre composite (CFC) structural components, including the wing centre box which helped to significantly reduce the weight of airframe.




Raj Mahindra, whose contributions to India's aircraft design & development have not been fully acknowledged

Then the curse of ugly politics intervened. Raj Mahindra was to be removed from the LCA programme. The then Chairman of the ADA Governing Body was cautioned that there would be serious delays if Raj Mahindra was not to be with the LCA, as he was the only person in the country then who had understanding and experience in the designing of jet aircraft. Nevertheless, in May 1985 the Chairman desired that Raj Mahindra be eased out owing to reasons that had nothing to do with his technical capability. If the Chief Executive of ADA did not command confidence of the Chairman in such matters, it was considered to be inappropriate for him also to continue. Accordingly they both tendered their resignations in June 1985, which were made effective in November 1985. The aeronautical community owes much to Raj Mahindra for his contributions to the cause of self reliance in Indian aeronautics.

Before the resignations became effective, a presentation was made on status of the LCA development, in July 1985 to the General Body of ADA presided by the Defence Minister. It received unanimous appreciation from all (including the Chief of Air Staff) for the progress made till then. The Minister was also informed that it was essential to meet the time schedules, as such aircraft were expected to counter the perceived threat scenarios at a future finite time. He was informed that in order to comply with this requirement, ADA had to obtain certain technologies such as FBW control systems from abroad, with Indian engineers working alongside the contractors. If the programme were to be delayed too long, the threat scenarios might well change, making the LCA irrelevant to the Air Force needs. The Minister was also informed that indigenous engine development by GTRE was essential even if this did not meet the time schedules of the LCA, so as to avoid facing a similar situation as with the HF-24. The GE F.404 was chosen as the interim power plant for the LCA, with the expectation that when the Kaveri engine was type-certified, it would become the standard engine.



Dr.Kota Harinarayana became Programme Director of LCA in 1986. Given the circumstances under which he took over the onerous responsibility, he did a commendable job of the task entrusted to him. The LCA prototype first flew in January 2001, but has a long way to go before the aircraft receives full operational clearance. Flight testing of such combat aircraft is not only demanding but time consuming.

At the first General Body meeting of the ADA in 1984, the then Finance Minister desired to know the anticipated cost of the LCA programme. He was informed that after taking into consideration inflation within the country and abroad, and providing 8 years for the first flight and three to four years for flight testing, the cost of development was estimated to be Rs.1250 crores, with about Rs.150 crores to be added for every year of delay. Series production was expected to start around 1995. Reportedly, some Rs.2700 crores have already been spent and hundreds of flight tests have yet to be conducted before the LCA can obtain type certification, thus involving more expenditure. Neglecting the development of FBW technology necessitated ADE giving a side contract to a US company. Embargos by the US Government following the May 1998 nuclear tests delayed the programme still further. Subsequent work done within the country indicates that FBW technology could certainly have been developed in-country at the beginning itself.

Considerable progress has since been made in the LCA development in spite of the early, avoidable, delays and several self-made hurdles. Years of experience in Indian aeronautics indicates that it was not a lack of intrinsic capability but lack of political will, professional leadership and a serious lack of forward looking R&D, that led to the situation. If we do not closely coordinate R&D with the industry, preferably along the lines of the Space Department, we will continue to repeat mistakes of the past. Even if the Indian Air Force does not fully accept the LCA, it is essential that its progress up to the type certification stage be pursued vigorously if only to learn how to design and develop such advanced aircraft for the future.

Though the above article is dated but a very nice article.

I have excluded other details else much can be talked about, LCA recieved FIRST funding in 1993 then heavy blockade in 1998 again with complete inhouse developement of FBW, and it took 20 years for typhoon to come to IOC from its first steel cut.

A nice Long Technically Breifed Artcile Coooolll......

LCA is tooo Slooow and too Late in comparision to JF17 dont you think it already consumed more the 25 years and JF17 in Final Stages and also goes into the production and line 2 planes are already deliverd to PAF ??? What you say ...

2 planes entered into service of the PAF, before JF-17 completed IOC and FOC. it has only did 500 hours of testing. This will only happen in PAF. Airforces around the world do not induct unless FOC and IOC are complete.

25 years of LCA. Really...ok. you win

I did realised I entered in talk with someone in denail in the first place. I wonder if the other gent who is thumping his chest of defining what is indigenous even knows that there is TEXAS INSTRUMENTS written all over RBE 2 of Rafale.

Rediculus comarision to start with, which show the level of understanding you have of the Indeginous effort.

There are off the shelf products and there are IP Products, which are available from specialized companie and countries. If you need an IC which is available off the shelf, you do not need to invent the whole process to make it. It makes better sense to purchase.

Now take the case of kaveri, the fan blade, which need to withstand high temp and stress require material for which India has no solution. what are the optiion as these are not available off the shelf in the market and the companies and countries who have the know-how keep it closely gaurded secret. Here the defination of "indeginous" comes, not for texas instrument IC's.:hitwall: Hope am making sense.



You are not aware of the other HF series of birds that was prototypes build but never entered service, the scientists literally ran to indraprastha for funds but alas the great soviet support was needed and flow of cash to their defence industry was needed as well. I'll post regarding them.

Before saying anything I hope I did said in my post to you that the report posted in first page has indeed many factual mistakes, and Chinese industry is ahead, I also gave you the main reason behind it from a notable scientist of IISC who analysed the aerospace present and future of India, Aerospace sector is ENTIRELY dependent upon the states will to pursue things aggresively, capabilities comes second which is dependent on the manpower available and experience the very first thing is what we lack, just was the case after Marut other designes were freezed the aeronautics sector came into dead stop. What do you think will happen if there comes no funding for MCA? Yes it will die in the lab.

I do am aware of that half hearted attempt, but seriosly if the people from airforce and power that be felt that they had no confidence in the ability of the scientistr, then where can I help.

All the rest of the copy paste job does not cut much ice in proving India is Aerospace power battling with china.

Can we postpone this discussion when LCA is inducted or after 15 years, which ever is earliest.:police:

Rejecting the rest of the bile, Nope I perfectly make sense and perfect comparison the issue is you dont know actually what I talked about which was not about IC's, I'm not talking about of the shelf aka COTS products, the LCA uses plenty of them , the MMR like uses the Sharc processor, incidentally I know persons who developed the Tiger Sharc DSP and the Blackfin and most of the work was done in India, anyways The RBE2 architecture originated in the USA - from Texas Instruments actually (Thomson was a partner on the program). The USAF was considering going for a passive array but then dropped the idea and went "balls to the wall" for an active array. That's how the PESA technology migrated to France. Obviously there is French contribution to it and as I said it is as much French as MMR is Indian.

Take for example the MMR, The MMR design is more Indian than the Gripens radar is Swedish (heck it is purely handed over stuff) , I have already clarified, please check the LCA thread there is a very good article regarding the developement of the airborne antennae system of its radar released by BARC who was working with ECIL, As of now Indian industry does not manufactures some specific precision components needed for some specific radar modes, here in MMR some specific components for the a2g mode only will be imported from Elta and will be later replaced by the ones made home. This was known from Aero India 2007. The integration help of the same subsystem will be provided by the OEM and validation of the same as usual, I find no problem in this other than your hyperbole of defining what is indigenous, surely the JSF radar's one of most crucial part called Reciever Exciter Modules of AESA will be imported from Europe, perhaps now you will tell me the APG 81 is a non-american radar system?

Now coming back to kaveri, get real dude! single crystal blade technology is something no amount of money will buy you from nowhere, India is making its own single crystal blade technology how good will be the MTBF compared to rolls royce is a easy guess, but then again it is something called propeitary knowledge base developed by likes of rolls royce for decades. the problem of kaveri is not with its single crystal blades alone, the need of better materials for better cooling in its compressor which inturn will stabilise the TET better and increase the blade durability is also a high factor. The design Remains completely Indian the problem is how to take that design into FOC stage, We have came long way doing that. There are many foreign components in the M88 engine as well which are developed by specialised MNC's in their respective field.

Presently there are three Kaveri production standards K9 and the K9+ and the K10. The K9 plus is perfectly up and running with 90% of the desired thrust, but the afterburner thrust remains around 85% or so. The k9+ prototype will solve these issues hopefully, The K10 prototype is where help from abroad is being sought to productionalise the prototype engine into smooth production line (even help was sought to materialise and mechanise the Arjuns state of the art production line as the finer tolerance of Arjuns highly capable Armour was very hard to mass produce by the OFB guys unlike the T series which has much looser armour tolerance), and to tweak the shortfalls.

The shortfall in the afterburning thrust can be due to LP compressor or Fan's component map seems to diverge from designed values, This could be one reason for wet thrust short fall. Could call for redesign / tweaking. Similarly research into better materials is going on as the need to increase reliability of the blades from changing them frequently.

They have already solved the vibration problem it seems like from a latest report, which is quite complex to solve, in similar fashion they will subsequently do the single crystal blade stuff albeit with much bureaucracy and ill funding which can dramatically speed up work if political babus wants to.

Lets see how complex can be this little vibration issue if analysed from a most simplest point of view, we all know One of the most simple problem of vibration issue that plague the GT is the dynamics of the rotor itself, viz. the problem of controlling high-frequency vibration of light weight, flexible shafting that is supported by bearings with an finite life. Any rotor, however stiff the supporting shaft will sag ever so slightly under its own weight (just like a bridge's span sags under its own weight) and that vibration is inherent when it spins, bearing wear or not. Enough stiffness can be built in to solve the above mentioned cases and are the easy part and any vibration and acoustics standard text at undergrad and masters level, along with tools built into CAD packages will let you get away.

The more complicated part is the harmonics, The GT is just an open pipe (just like a flute), The problem is with so many components and stages and complex turbo machinery is that it is difficult to predict accurately about the resonant behavior right upto 6th harmonics or so, given the natural vibration modes of the huge number of components, I believe what they do is that they try to keep the number of turbine blades as prime numbers to avoid resonance, Make no mistake. The engineering challenges are huge and you will never learn these until you actually do this hands on and implement a design and learn from the inevitable mistakes. A CAD software or a text book is not going to throw the answer at you. This engineering "secret" sauce is one of the cakes what the top guys have learnt the hard way over 60 years and is a very closely guarded secret.

World engine developement never followed a fixed route of developement to reach a fixed design goal from first unlike what we were forced to do being late in the game, they developed a thrust level first then tweaked/redesigned it to gain the required thrust level, here GRTE is in such a position that it cannot install the engine in LCA if it gives 18000 lb's of thrust as they need the thrust of it to increase the thrust of the GE IN20's to be worth installing, and also not to kill the time required, you need to realise how hard it is to develope a engine directly to reach >20000 lb's of thrust in first try, they have done a long way, mis-management did happened in GRTE but thats another method of discussion.

To simply put it some shortfalls of the K9+ series will be solved in K10 series with colaboration, but no one will give you single crystal blade metallurgy, we have to come up with our own in that. none of this parametres denotes the engine being non-indigenous other than your insecure mind from nationalistic point of view. On the positive side they have been working masisvely on IR stealth and reduction technology and has achieved good amount of success, but then again developing it is way easy than developing single crystal turbine blades. Inspite of mismanagement, high bureaucracy, low payscale, and severe attrition they have came quite far.

I will await the next 20 years and will see what aero engine Pakistan will come up with.

Oh please. India refuses to sell weapons to Sri Lanka because the Tamils in India will get angry and thus Sri Lanka has to rely on Pakistan and China for weaponry. Infact the Pakistani Rocket Launcher Systems that we sold to Sri Lanka devastated the LTTE in 1996 which led to the capture of Jaffna.

Oh like the time that India's disastrous deployment of combat troops in Sri Lanka to show the world that India has arrived at a global stage.

I had to reply to this post involving tamils. pl. don't make comments on the tamil fighting for its for too complicated that pakistan can imagine. in fact most indians don't know exactly about this, save some of the pro tamil movement tamilians who actually supported the LTTE even when IPKF was sent.

btw, the pak rocket launcher systems didn't "devastate" the LTTE in '96 as you wish, for they weren't neither pakistani in actual origin, nor was jaffna fully taken by sri alnkan army for a prolonged period. LTTE has actually made sri lankan army (irrespective of pak weapons) literally kneel before them. First visit sri lanka before you make such comments. The LTTE is literally running a parallel govt.
