HAL Tejas | Updates, News & Discussions

What happened to LSP-6? It was suppose to test higher AoA.

The dream of fitting Kaveri engine being developed indigenously into the home-grown Light Combat Aircraft LCA-Tejas appears to be as good as over.

"Kaveri engine as such will never come into LCA", P S Subramanyam, Director of Aeronautical Development Agency (ADA), a DRDO lab, which is the nodal agency for the design and development of LCA with HAL as the principal partner, told PTI here. Noting that LCA-Mark 1 and Mark 2 will have engines from GE, he, however, said the LCA would support Kaveri engine's flight tests and demonstrations and certification.

"As and when there is support required by the Kaveri engine, LCA will give support of its flying test facilities", Subramanyam said. He expected flying tests of Kaveri engine to lead to its fitting into unmanned air systems. Subramanyam said Kaveri engine-fitted LCA would not go into the Services. "In the production aircraft (LCA) going into the Services, Kaveri engine will not be there". Kaveri engine, originally intended to power the LCA, was taken up for development by Bangalore-based Gas Turbine Research Establishment (GTRE) about two-and-half-decades ago but the project has been dogged by delays, with the DRDO lab not being fully able to overcome technical challenges and development snags.

Scientific Advisor to Defence Minister and DRDO Director General V K Saraswat said unmanned air systems would see the integration of Kaveri engine for different applications. Kaveri engine will be demonstrated on board an Indian origin aircraft, added Saraswat, also Secretary in the Department of Defence (R&D). Meanwhile, Subramanyam said the first LCA produced by HAL would be ready in the third quarter of this year.

Kaveri flops, LCA-Tejas to fly on US engines

Very old news....was posted here a week back.

 

[Che Guevara]

I don't care if tejas is flop, more important part of this project is that its completely Indian work and also kaveri..... continue with it....if not today, after 10 years we will be capable of make our own quality aircraft.....

@nabil_005: This issue is discussed million times.

a> Kaveri engine was decommissioned from LCA project many year ago. Kaveri project for LCA was a blunder (As India had no choice as world didn't provided us engine in 60s). It would be better if Management would have made kaveri seperate project.
b> Unlike some other country (USA,Russia) India is unwilling to induct pre-mature fighters. As USA and Russia develop/research fighter they induct pre-mature fighters...

IAF will not induct LCA unless
a) It has night flying capability
b) It has optimum TWR what IAF need.
c) It has Missile foring capability
d) It has specified radar and EW suits.
e) It has ground attack capability.


I was browsing one of forum thread I was amazed to read that one of fighter (claimed 4.5 gen fighter) acquired by one country had no night flying capability , no missile firing capability and many more. These features added in upcoming blocks.
If IAF agree with it, LCA would have inducted 5 years ago in IAF.

Which fighter and country was this ?

Karan, I will search for that comment and post here, But worried it will flame d!ck comparing and derail the thread.

From your reply it seems you are talking about JFT.. If yes, then avoid..

Kaveri flops, LCA-Tejas to fly on US engines

YES, it is clear that as of now; the Kaveri is not selected to power Tejas. Because it has not met the specific requirements for Tejas.

But does it work or not? Is the Kaveri project junked?
The answer to both questions is NO.

The Kaveri project started as a project to power the LCA. But since it did not meet the specific requirements, it has morphed into a development for various engines which are in developmental phase as we speak.

One of them is the KMGT (Kaveri Marine Gas Turbine) which is intended to power ships. Since it is free of the specific requirement/restriction of size and weight of the aero-engine it has given encouraging results. The DND has taken it up enthusiastically and it will become a likely candidate for future IN ship propulsion. Once the design is acceped it is a prime candidate to replace the Ukrainian built GT engines in IN ships during Long Refits/MLUs.

Another spin-off is a down scaled version that will be used to power UAVs/UCAVs. Even this project is well under-way.
Other smaller versions already power compact power units for critical power applications and APUs.

If the Kaveri project had not been embarked upon; India would have made very little progress in GT design and manufacture.

Leave it there. The Design and Development Philosphy behind the two projects is vastly different.
And there are very good reasons for that.

Just one of the reasons is the "factor of critical necessity".

True, but the ease of development, inducting and upgrading is also vastly different and shows the advantages they have now. A manufacturer that is aimed on making things simple and according to their capabilities, but upgrading it later with more capable and modern techs and capabilities.
That's why they are inducting the 3rd squadron now, while we still play with prototypes, even if as capable.

Read it in context.

 

[sancho]

You overlooked the next lines:

No I read them, but the necessity has nothing to do with the failures we made in project managment and planning. That is why our fighter is still not in serial production, while theirs is.
We wanted a more capable fighter and that is was the right way to go, but we should have done it in a similar simple way, by choosing ready and available engines and radars.

Sancho, I was not discussing or dissecting the project(s). I simply explained the underlying reason (only one of them) for the difference between the Design and Development Philosophies.

A FART, Brain fart more precisely, after having too much of LCA reality food.
Indians have bad digestive system.
