What abt LCA a French design.. Israeli avionics.. Radar... Russian-Israeli weapons... American engine and still not inferior and not even operational..
In 1983 IAF realized the need of an indigenous combat aircraft for two primary purposes. The principal and most obvious goal was the development of a replacement aircraft for India's ageing MiG-21fighters.To better accomplish these goals, the government chose to take a different management approach, and in 1984 established the Aeronautical Development Agency (ADA) to manage the LCA programme.
The IAF's Air Staff Requirement for the LCA were not finalised until October 1985.Project definition commenced in October 1987 and was completed in September 1988. Dassault Aviation of France was hired as a consultant to review the PD and provide advice based on its extensive aviation expertise. The PD phase is a critical early element in the aircraft design and development process because from this flow key elements of the detailed design, manufacturing approach, and maintenance requirements
The LCA design was finalised in 1990 as a small tail-less delta winged machine with relaxed static stability (RSS) to enhance manoeuvrability performance.
The Tejas employs CFC materials for up to 45% of its airframe, including in the fuselage (doors and skins), wings (skin, spars and ribs), elevons, tailfin, rudder, air brakes and landing gear doors. Composites are used to make an aircraft both lighter and stronger at the same time compared to an all-metal design, and the LCA's percentage employment of CFCs is one of the highest among contemporary aircraft of its class. Apart from making the plane much lighter, there are also fewer joints or rivets, which increases the aircraft's reliability and lowers its susceptibility to structural fatigue cracks.
The tailfin for the LCA is a monolithic honeycomb piece, an approach which reduced its manufacturing cost by 80% compared to the customary "subtractive" or "deductive" method, whereby the shaft is carved out of a block of titanium alloy by a computerised numerically controlled machine. No other manufacturer is known to have made fins out of a single piece.
The use of composites in the LCA resulted in a 40% reduction in the total number of parts compared to using a metallic frame. Furthermore, the number of fasteners has been reduced by half in the composite structure from the 10,000 that would have been required in a metallic frame design. The composite design also helped to avoid about 2,000 holes being drilled into the airframe. Overall, the aircraft's weight is lowered by 21%.
So the Indigenous development of LCAs quadraplex redundant all axis FBW,sensors,actuators &DFCC doesnt make it indigenous?--------( point 3 )In 1992 the LCA National Control Law (CLAW) team was set up by the National Aeronautics Laboratory to develop India's own version.The CLAW team's scientists and mathematicians were successful in developing their control laws, but could not test them since India did not possess advanced real-time ground simulators at that time.
As it was being developed, progressive elements of the coding were checked out on the "Minibird" and "Ironbird" test rigs at the ADE and HAL, respectively. A second series of inflight simulation tests of the integrated flight control software were conducted on the F-16 VISTA(Variable In-flight Stability Test Aircraft) simulator in the U.S. in July 1996, with 33 test flights being carried out. However, Lockheed Martin's involvement was terminated in 1998 as part of an embargo enacted by the U.S. in response to India's second nuclear tests in May of that year.
The NAL's CLAW team eventually managed to successfully complete integration of the flight control laws indigenously, with the FCS software performing flawlessly for over 50 hours of pilot testing on TD-1, resulting in the aircraft being cleared for flight in early 2001. The LCA's maiden flight was made by TD-1 from National Flight Test Centre (NFTC), near Bangalore, on 4 January 2001, and its first successful supersonic flight followed on 1 August 2003. TD-2 made its first flight on 6 June 2002. The automatic flight control system (AFCS) of the Tejas has been highly praised by all of its test pilots, one of whom said that he found it easier to take off with the LCA than in a Mirage 2000
Actuators,Sensors developed indigenously
HAL's Hyderabad division and the LRDE were selected to jointly lead the MMR program and the radar development effort began in 1997.
The DRDO's Centre for Airborne System (CABS) is responsible for running the test programme for the MMR. Between 1996 and 1997, CABS converted the surviving HAL/HS-748M Airborne Surveillance Post (ASP) testbed into a testbed for the avionics and radar of the LCA.
The coherent pulse-Doppler Multi Mode Radar is designed to operate equally effectively in the Air to Air and Air to Surface domains. Jointly developed as an Indian – Israeli venture, it features multi-target Air to Air Track, Hi Resolution Synthetic Aperture Mapping and specialized Air to Sea modes. The radar facilitates all weather employment of a variety of Air to Air and Air to Surface Weaponry, and is the primary targeting sensor on the Tejas.
The electronic warfare suite is designed to enhance the survivability during deep penetration and combat. The LCA's EW suite is developed by theDefence Avionics Research Establishment(DARE) with support from the Defence Electronics Research Laboratory (DLRL). This EW suite, known as Mayavi, includes a radar warning receiver (RWR), Missile Approach Warning (MAW) and a Laser warning receiver (LWR) system, self-protection jammer, laser warning system, and chaff/flare dispenser
Open Architecture Computer (OAC) designed and developed by ADA, combines the functions of earlier mission computer, display processor, video switching unit and mission preparation and retrieval unit. It is designed based on open system interfaces standards, which provides interoperability, scalability, and portability. OAC drives three multi-function displays, HUD and the helmet-mounted display. This open architecture design will allow the designers to continuously adapt and upgrade Tejas to meet the challenges of modern warfare.
The cockpit has two 76mm×76mm colour liquid crystal multifunction displays developed by Bharat Electronics, a head up display developed by the government-owned Central Scientific Instruments Organisation (CSIO) in Chandigarh, a liquid crystal return-to-home-base panel and keyboard. The pilot also has a helmet-mounted display and sight (HMDS). The hands on throttle and stick control system minimizes pilot workload and maximizes situational awareness.
So these too,doesnt make Tejas Indigenous?---------( point 6 )GTSU 110
A Jet Fuel Starter has been designed and developed by Engine Division of HAL, Bangalore, especially to start the engine of Tejas on ground and in the air. Design optimisation of rotating elements and shaft has been achieved by use of 3-D modelling, dynamic and stress analysis software to reduce weight of the JFS with the safe margin for shaft critical speed and element's resonance frequency as well as to reduce vibration and noise levels.

Aircraft-Mounted Accessories Gearbox
An Aircraft-Mounted Accessories Gearbox (AMAGB) has been designed and developed for TejasA. It is a lightweight, single-input, multi-output gearbox, which takes its input drive from engine through a power take off shaft at a rated speed of 16810 rpm. AMAGB has a high power-to-weight ratio and a self-contained lubrication system. It carries four aircraft accessories on its output pads, viz., two hydraulic pumps (60 kW @ 6000 rpm each), one generator (40 kW @ 7950 rpm), and one starter unit. Together, these cater to a major part of hydraulic and electrical power requirements of the Tejas and hence forms a crucial part of its secondary power system.

Landing gear for Navy & AF version
We'll guess what new money poor people.. They went to waste.. And Dnt even get me started on the indian assembled ..German designed MB heli aka dhruv .. Whose parts are imported from 36+ countries .. Is tht the only thing you assembled ? Lol
HAL Dhruv is said to share many design features that are derivative of the Kawasaki BK-117 and EC-145, which is a variant of the BK-117. HAL started development of a new 12-seat helicopter known as the ALH (Advanced Light Helicopter) in July 1984. It was designed with assistance from MBB in Germany. It followed a similar layout to that of the BK-117 although it is a larger aircraft. The Dhruv might look a bit like a BK 117 but it is quite a lot larger and has a 4 bladed not 2 bladed tail rotor.
Indigenous Integrated Dynamic System (IDS)Indian Army and Air force wanted engines with power higher than TM333-2B2 for
Dhruv helicopters. An agreement was signed with M/s Turbomeca, France in 2002 for the
Co –development of Shakti engine ETBRDC was entrusted with the design and supply of
the oil pumps, oil cooling system, the filter unit and the external dressing. Engineers of
ETBRDC also took part in casing modelling, rotor dynamics and stress analysis at
Turbomeca, France.
A nose-mounted FLIR pod produced by the MoD-owned Bharat Electronics Ltd will be used for for target acquisition. The LCH’s four-axis auto-hover and digital automatic flight control system have been developed in-house, while the DRDO’s Bangalore-based Defence Avionics Research Establishment (DARE) is developing the defensive aids suite, which includes a combined radar/laser warning system and Bharat Dynamics Ltd-developed countermeasures dispensers.
DARE has also developed in-house the digital mission computer and pylon interface boxes. The flight control actuator system has been co-developed by HAL and the UK-based APPH
Lmao a few dollars and still tht took you decades and when we are engaged in a war? Lmao and a non existent middle class against 45% stron Pakistani Middle class ??
Lmao how's the 20 cents or something definition of above poverty line goin??
First thing, Pakistani engineers and PAF officials were present all the way through JF-17 designing program. It is a "co-design" of Pakistanis and Chinese. So we DID get alot of help in design etc. Majority of avionics are being made in Pakistan..we are integrated all of our indigenous weapon systems on JF-17 because we designed and created the software ourselves too.
secondly, indians did not make any breakthrough in design. LCA's design is nothing "new" ...No new feature was introduced.
Also, as much as you would like to "console" yourself about this indigenous design thing, in real world..it does not matter. Tejas is a failed project now because its time has gone. It adds nothing new to iaf's strength..delays of DECADES as made it a useless project. And that is pretty much agreed by senior members of your country too...
Pakistan took the more efficient,smarter move and co-designed, co-developed a fighter aircraft with its most trusted ally...creating a superior platform than tejas..and the JF-17 project has been a supreme success, Mashallah. PAF is actually surprised how brilliant the project turned out to be! It has exceeded ALL expectations. All deliveries are on time (with little hitch-ups of few months ...thats it!)
It already recieved IOC 2,Is in serial production & FOC would be in 2015.
Development of every 4/4.5 gen in service today took decades-Eurofighter,Rafale.But LCA design wasnt finalised till 1990 & full scale funding came only in 1993.So Its just 2 decades time-comparable to other projects.
And for the bolded part-
I said on your own .Not like 20 Pakistani engineers working with 100 Chinese engineers and then claiming it as a Pakistani achievement
Yes it is a SAAB Safari retrofitted a new American engine,US made fuel injection system.
Only ~40 Super Mushaks were made.And you exported 'hundreds of them?'.Mushaks made are around ~200 of this 149 are used by PAF.Again nothing even close to one hundred.And you exported license built SAAB supporters?Whoa.....
Done almost 50 years back.HAL HT 2,HF 24 Marut & HJT 16 Kiran.Now comeback when you have a indigenous design
Care to name a few?You are bragging about JF 17 like its a entirely Pakistani product.
It was designed for AoA over 30 degrees.And it have potential to do 28 degree.Just that JF 17 have been tested to 26 degrees wont make JF 17 superior.
increase detection 'rage' by 80 'kilo newton'?? .The MMR has the range of more than 100 km.Ever heard of 'Radome'?
You have posted the composite components of JF 17,nothing except radome,wing leading edges etc.Nothing when in comparison to Tejas,which has the highest percentage of composites among fighters.
Can you prove that Y Duct used in LCA is not enough?Y Duct on LCA have been optimized in a windtunnel & is enough for LCA.
And here it is,DESERT FIGHTERS logic.
Super Mushak ,which is an upgraded SAAB Supporter with an imported engine,fuel injection system & new instruments is indigenous!!
But LCA,designed in India by Indians is not indigenous,because it uses American engines!!
So lets see,how much indigenous LCA is.
Here is a brief development history of tejas
Yes, Dassault was hired to review the Project definition,I hope you know what that is
The Design
Early proposals & wind tunnel models...
And finally...
Various windtunnel models were tested on NALs wind tunnels-
Air intake
Aeroelastic testing
CFD Analysis by NAL.( I guess you know what CFD is ) NAL is a very capable organisation,which have even done testing & designing of Space Launchers & Reusable Launch Vehicles
So,an aircraft design developed by Indians ,using Indian infrastructure like windtunnels,paralell computing,CFD anaysis capabilities is not Indigenous??------------( point 1 )
The Airframe-Composites
This will take considerable expertise & infrastructure to make components like Carbon Fibre Wing,single piece tail fin etc.All of these are done Indigenously.Now that doesn't make it Indigenous?-------------------( point 2 )
27th January 2014All segments in the aerospace industry, including civil and military aviation and space, are showing a significant level of growth because of which several companies want to be part of the growth story, he said. He said one would be surprised to know that 110 International Aerospace companies have their headquarters in India. Sekaran said liberalisation of civil aviation policies, strong domestic manufacturing base, cost advantages and well-educated talent pool were some of the factors driving the growth of India's aerospace industry.
