Interesting, but sadly no sign of self-criticism about the developments that failed, but since it's an interview for the Tejas site, that would have been surprising anyway.

However, this part shows why LCA was and is an important development for India:



It is the base for our aerospace industry, the base of knowledge and experience we slowly build in this area. That's why even if it is the low end fighter of IAF and even if it is delayed, it is most important to finish the project and not simply switch to the next one!
Finishing LCA MK2, getting it into operational service in numbers and reflecting about the things that went wrong during this development will get us a big step further, especially when we can learn and improve ourselfs at the same time via MMRCA offsets, ToT and the FGFA co-development too.

1) Building the base - LCA
2) Understanding and integrating latest techs - MMRCA
3) Jointly developing next generation techs - FGFA

That's what we get when we use our indigenous strenght besides the advantages we get through our foreign relations!

with all due respect dear sir,

i would like to add the following......

1) Building the base - LCA
2) Understanding and integrating latest techs - MMRCA
3) Jointly developing next generation techs - FGFA
4) Independently develop the High End / High Tech fighter - AMCA :tup:
 
.
Please dont forget that it is an LCA being allowed to fly in Pakistani airspace after our permission reserved for its sole use.
:angel:

ha ha, its like you have been invited to Farnborough Air show for an aerial performance and suddenly saying you can't scramble your jet..its an airspace violation if you fly and will be shot down.

Oh no..
you may do all the pirouettes, loops.. weapons displays. and the like...after all.. you are our guest here.
But do pay the parking and apron fees.. and be respectful of your hosts.

I think moderators are doing a fair job..

If i was in his position, i would be much worse ..;)

You can't ask parking fee to Airbus & Boeing in a business jet air show. Without them, whats the fun at all?

I'm not disagreeing buddy

Nah! Its like the foxbat mission in Pakistan a couple decades back when it overflew Pakistan but you had nothing to catch it with :D

You can only do that, if the first 3 steps are done, otherwise we can't do it alone and that's why we need foreign support for radar and engine developments.

hahaha.... for a moment i thought.. wow an appreciable chinese fellow here... and not later than 15 mins i realised after reading the article "Oh hey! another LCA basher"

This article is from a blogger : ??-?-???LCA?2011?-?

i searched for the credibility of this news everywhere online and i couldnt find a source for it and mr.wanglao has posted this link here which sounds funny.. The blogger didnt mention any source for the story he's posted either... I'v read some good chinese stories but never thought chinese storytellers are so capable of narrating a BS in a realistic way....lol

The blogger has brought out every single attribute of Tejas to comment and he's written a perfect story. Below is the story for any1 to give a credible reasoning:

January 26, 2011 India's Republic Day (National Day). As usual, held a grand parade, and demonstrate its defense R & D achievements. It is expected that LCA will fly over head, shows that this aircraft has a combat strength. Indian Army fans dismayed to find that the LCA trainer PV-5, or even, as usual was on the trailer slowly marching in the parade. From the outside, this is undoubtedly tell the public, this is still a bear to use the aircraft. Worldwide, probably is the Indian facial skin is so thick, dare to show their proud but useless things in this way.

Celebrate this stage the results of IOC has just ended, the bonus of the hair ends up everyone's pockets. HAL announced a very low-key manner, the LCA is just to get the IOC-1, under a project node is to get the IOC-2, rather than the FOC. In other words, LCA did not really get the IOC. HAL have to admit, LCA fighter IOC-1 certificate is incomplete, because many of the IOC must test not done. They need to continue the flight, the subjects did not fly after fly finished. HAL is expected to 2012 in order to get the IOC-2.

IOC certificate get our hands on, actually there are a lot of subjects did not test flight, it sounds like is ridiculous. In the end so what subjects did not fly? It can go. Light HAL revealed airborne weapons throwing, air to air / ground attack, night subjects never flew. Angle of attack of the LCA is only 20-22 degrees away from the design requirements of 26-28 degrees early na. Maximum use overload can barely fly to G-6 from the real design requirements of 9 G far worse. Speaking of the old strong -5 to achieve 5.5. The LCA design flight speed of Mach 1.8. But it is only in the test flight reached Mach 1.3 (a 1.4 Mach). LCA, low-altitude maximum speed and continued circling the rate did not meet the design requirements. The LCA design flight altitude (16,500 m, the 2011 year is raised to 16,000 m) have never come close to the flight test.

In general, LCA is far from reaching its design requirements. HAL understand that you will say to the LCA aircraft flying the aircraft but also the whole for the original design value 9G. Internal control that flew 8 G sorted China and Pakistan jointly developed the JF-17 Thunder the same even confessed later.

Zen said: This is called God Ma gray chicken.

HAL on so easily to the Indian government and the public also played out a return, called outsiders looked almost to tears, called the India Army fans wringing. Mess pair of bears like the frustration of one of the only HAL knows best.

LCA fighter problems, the old concept has long been to associate the pulse that is overweight.

Wait and see by: Mangrenmoxiang the pulse for the Indian LCA since the reason rather than fly!

LCA fighter overweight problem is not serious. Its design empty weight of 5500 kg. Decades, HAL teeth stare offerings by heaven, the LCA empty weight is the number refuses changed. Boast of so-called 45% of the weight of the composite material, and therefore very light. LCA test flight in poor performance, the accuracy of the outside world on the 5500 this figure has always been very skeptical. HAL has been claimed that light composite materials, is conducive to weight loss. HAL long term attempt to lose weight for the LCA, but unfortunately do not have that diamond, the LCA is more less the heavier. 2011, the LCA has been referred to the Air Force test pilot, HAL to the basic data of the LCA must be submitted to the Air Force, its empty weight of the secret can not continue to cover up. HAL This timid morning train new empty weight: 6560 kg, 1060 kg more than the previous design specifications, an overweight of 19%.




The figure shows the use of composites in the surface of the LCA fighter.

Dark gray for carbon fiber composites, accounting the majority of the skin.

Green for glass composite materials used for the vertical tail at the top.

The yellow Kevlar composite materials for the nose cone.

White aluminum alloy, used for air intakes, wing front and tail.

The top left of the circle shows the proportion of various materials, which accounted for 45% of the composite, aluminum accounted for 43%, 5% titanium, steel accounting for 4.5%.

LCA fighter once known as the youngest of four generations of aircraft, and now this new empty weight data have been flat and Pakistan's JF-17 (6 586 kg). Do not forget, the length of the LCA fighter is only 13.2 meters shorter than the JF-17 14.93 m 1.73 m. In the same empty weight conditions, LCA is a shorter than the JF-17. Means that HAL LCA is extremely narrow body space to accommodate an excessive weight of the structure and the necessary equipment, the result makes the LCA flying qualities comprehensive lagging seriously behind the design specifications.

Even so, the LCA, after all, the use of the F404 engine (thrust 53.9 kN, 85 kN with afterburning) used with the JF-17 Klimov RD-93 (thrust 51.2 kN 84.5 kN with afterburning) performance approximation. Even overweight, in the empty weight and engine conditions, and normally the LCA and JF-17 flight performance should be similar. The flying qualities of the LCA and the JF-17 is really too bad, such as the Mach number of JF-17 has already reached the design value of 1.8, while the LCA can only reach Mach 1.3 to 1.4. It seems The reason for this difference seems to have not only with overweight explained there might be other reasons. HAL be kept strictly confidential, outside this of course can only guess.

HAL plans (Note that the "Plan") in 2013 to receive the United States tailored specifically for LCA F414-GE-INS6 engine, the heart of another better for the rod, spoil the LCA. F414 size and weight similar to F404, but its maximum thrust up to 98 kN, 15% more than the F404.

The LCA has been for the overweight pay a heavy price, its airborne fuel will certainly be greatly reduced. A ton more empty weight less with one ton of fuel, this should be easy to understand. Reduced fuel load in the machine rely on the external fuel tank compensation, the result is a weapon mount must be a corresponding reduction in This vicious cycle of the flight envelope and operational performance of the LCA has shrunk accordingly. For a greater fuel consumption of the F414 engine in the future, of course, the quality of its flight can be improved to some extent, as to be able to improve and to what extent, the outlook remains optimistic. The F414 engine is only piecemeal, stop-gap palliative measures, apparently unable to solve the chronic LCA overweight. Dress high-thrust engine will certainly have to increase the weight of the structure can be expected that the LCA and fuel consumption indicators (such as combat radius, and weapons mounted amount, etc.) in its Mark-II, but will decline further.

LCA into this spiral to be regarded as not pull it out.

The ugly words to F414's LCA is not enough, the Indians certainly incite Lai Meiguo engine does not give a fresh installed in front. A self-styled "superpower" with the strong words of a true NB superpower waiting to be spectacular. Finally, who to who repairs hard to say.

The old concept has long been the HAL out of mind, they have to reduce the proportion of the use of composite materials, aluminum alloy substitution in order to achieve weight loss. Indians not understand this truth, but they have always refused to do it.

Why Indians have to drill a composite material of this dead end? This is obviously the air war theory. Indians believe that the composite materials can greatly reduce the reflection of radar waves, so you can make the LCA to achieve stealth. Close to the enemy fighters with the same level (such as the JF-17 Thunder) when fighting is not easy was found locked and will be able to use stealth advantage before the enemy discovered the target, and then use its BVR missile first attack, which made air combat victory. With such a magic weapon, even if the flight performance almost does not matter, anyway LCA do not want to engage in any close combat.

Starting from this idea, HAL to fight to the death does not change his mind, and prefer overweight expense of flying qualities and weapons mount, but also keep the stealth performance composite unshakeable has been used now. Of course the LCA stealth, and the F-22 than worse with grade. Composite materials, no matter how good, the body can not reach the realm of golf that is not in accordance with the modification stealth radar cross section.

LCA fighter test flight planned in 2011 throughout the year ranked the full to the brim, the test group in full swing in busy flight test in accordance with the requirements of the IOC-2. I did not expect April suddenly something happens. An LCA in the ground taxiing to a fuel leak. Fortunately, the problem found on the ground, that if in the air, the consequences would be extremely serious. Air Force and HAL can not be taken lightly, and immediately ordered the entire LCA fleet grounded all. Since then, the HAL has spent four months transforming the oil and hydraulic systems, the correlation structure has been modified, and finally solve the leakage problem, to August, to restore the LCA test flight.

April 29, 2011, the Air Force announced that the LCA has completed a six-night flight tests, including one Israeli radar and Litening targeting pod attack.

According to the announcement in May 2011, the LCA has completed only gravity bombs put experiment and R-73 short-range air-to-air missile launch. Later revealed the news that the R-73 is the target launch is probably the detection of missile pylons and missile smoke whether from the LCA engine.

September 2011, LCA began in Jaisalmer, laser-guided bomb delivery, and electronic warfare test.

Subsequently, in November, the LCA team stationed in the southern tip of India, Goa, Hansa Ji to sea-level flight tests, as well as R-73 air to air missiles aimed at the launch.

But regardless of the Air Force how hard we try, the end of 2012 to get the FOC be regarded as completely No way.




October 3, 2011, the Air Force Commander Browne bitterly announced the FOC will be delayed one year to the end of 2013. Surprisingly, November 18, he announced that the FOC is expected in 2014.

After the date of the IOC and FOC will not do it again postponed, you judge for yourself, anyway, the Indians themselves pumping their own mouth or very ground, do not believe you read on.

In addition to the above test flight in 2011, the Indians have a limited production series (LSP) follow-up machine also have significant expectations. Which the LSP-6 machine is designed to fly the angle of attack. Has 11 LCA Tian Fei, the angle of attack is always at 20-22 degrees, is far less than the design target of 28 degrees. This makes the LCA mobility greatly reduced. HAL back to see what you want out of the active-duty MIG-21, how people will be able to fly out of the 28-degree angle of attack? Now a lot of effort specifically made a flying angle of attack of the LCA, this approach can only rely on weight loss in the same aerodynamic layout, that is independent of the device within the machine removed, to the LCA to a large thin. This approach seems to cut corners trying to cheat is suspected. However, LCA is for so many years is by the set of mixed over, and then play back there why not? As long as there is an LCA flying out of a 26-28 degree angle of attack, presumably LCA can muddle through. If the other LCA still fly no such angle of attack, and to do so, what implications does ultimately to equip the Air Force marks an LCA?

Or flicker yourself?

The last two limited production series is also long overdue. LSP-7 and the LSP-8 has long been off the assembly line, HAL had also vowed to ensure the LSP-7 will be the maiden flight in August 2011, but in August, nothing has happened. Subsequently HAL time to release a new first flight date, but it was not until February 5, 2012, two LCA failed to God.

The rest only could get out to show off the LCA Navy prototype NP-1. NP-1 has been off the assembly line as early as July 6, 2010. HAL roll out the red carpet to joyfully celebrate its birth.

Can clearly see from the picture, the NP-1 is a two-seat trainer. In order to adapt to the additional impact of the landing of an aircraft carrier deck, its landing gear is newly designed, more stout than the landing gear used on the LSP. The body structure of the NP-1 corresponding to the strengthening and the installation of the aft hook. In addition, the NP-1's head changed to slightly drooping to improve landing when the pilot's view. All this gave the NP-1 increased the weight of the structure to make it more heavy. NP-1 in the future way to slip jump take-off roll distance is very short, double overweight NP-1 can only be a substantial reduction of plant oil and external weapons can barely take off. The HAL did not dare to disclose the NP-1 empty weight data, but they also did not forget flicker outside, said the NP-1 plug-in to a staggering 3.5 tons.

In accordance with the established practice of the Indians, the Navy, announced an order for six off the assembly line in NP-1.

Did not think that NP-1 than the LSP-6, 7,8 more disappointing. The new landing gear even 400-500 kg overweight. NP-1 first flight date has repeatedly announced and postponed several times. December 4, 2011 Indian Navy Festival, HAL to an earlier serious oath to the NP-1 in the first flight of the day lying shamefully off the air. Afterward the HAL refused to give up, put on the spot ruthless, said before Christmas 2011 NP-1 bound to its first flight. By the end of December, NP-1 is still spinning on the ground and refusing to fly. The announcement to be lost again. HAL public fan post of his big ears. As of today (February 5, 2012), NP-1 has been off the assembly line 19, when its first flight remains a mystery.

Throughout the performance of the LCA project in 2011, can only be described as lackluster to. Throughout the year, a new LCA first flight, the IOC and FOC are not completed by the node, tossing a year, the result is the entire plan to postpone for two years.

HAL and the LCA in 2011 several outstanding highlight is:

No crashes, maintaining records, rare.

(2) exercise the team.

Government agreed to continue funding to engage in LCA down.

In fact, the Indian Air Force has long been impatient for HAL and LCA. They are really interested in is not the LCA, but how to buy the Eurofighter as soon as possible a good lean fighter facing the embarrassing situation. The Government of India, they certainly understand that, no matter how big the setbacks and difficulties, in order to eventually establish a decent domestic fighter industrial or Degen TG was like, teeth and stick to it.

Then TG Ku Haha make an airplane having a spirit of braving the Indians now?


Please readers if u can google up and find any credible explanation for this story post me with updates if there's any source for this rubbish...!! Thnx

It is not a story, it is the objective truth. LCA is seriously lagged behind. HAL should instrospect the reason of lagging cause they should take responsibilty for all the Indian military fans in India. Lots of Chinese Scientist get cancer in the hardworking and insist staying on his post until death. Indian scientist should learn the enduring hardship spirit of Chinese ones. If you love your country, prepare die for it.
 
.
I urge India to cancel the Tejas and buy the MiG-35 instead.
Although LCA is not that successful at this moment, but al least it teach indian how to build a combat airpalne. This will never gonna be gained through procurement. It is a right decision for India buying Rafale rather than MIG-35. Mig-35 is a short leg.

The sole responsibility of delay goes to the armed forces. The armed forces are not flexible, They want final finished product. Like I said Earlier other country forces compromise on quality where as Indian armed forces show adamant behavior.

There are many reason behind the armed forces delay tactics.
