Light combat aircraft ' Tejas ' to get foreign engine.

India's quest to develop its own multi-role supersonic fighter, the Tejas Light Combat Aircraft (LCA), continues to falter even after 25 years. Its heart also needs a foreign transplant surgery now to function properly.

The defence ministry has asked two leading aeroengine manufacturers, General Electric (US) and Eurojet GmbH, to submit their bids within three months to supply 99 engines, with an option for 49 more, for the Mark-II version of Tejas.

With GE F-414 INS5 and EJ-200 being the engines in contention, eight will be bought off-the-shelf, while the other 91 will be manufactured in India under transfer of technology in an estimated $600 million contract.

This comes after the indigenous Kaveri engine failed to pass muster even after two decades of development at a cost of Rs 2,839 crore. While the first 20 Tejas will be powered by GE-404 engines, the next six Tejas Mark-II squadrons (16-18 jets in each) will have the new more powerful engines.

Sounding the death knell for Kaveri, IAF has shot down the offer of Defence Research and Development Organisation (DRDO) to co-develop and co-produce the "90kN thrust class of upgraded Kaveri engine'' with French company Snecma to meet Tejas' operational requirements, defence minister A K Antony told Parliament on Monday.

DRDO contended the modified Kaveri engine would provide "comparable thrust throughout the flight envelope of Tejas''. Moreover, it would require minimum changes in airframe to integrate this engine without affecting the weight and configuration of the single-seater fighter.

"IAF, however, has suggested a proven engine that is already in production and flight-worthy for meeting immediate requirements. The RFP (request for proposal) has been issued to reputed engine manufacturers,'' said Antony.

Incidentally, the GE-414 and EJ-200 engines power the American F/A-18 and Eurofighter, respectively, two of the six jets in the race to bag IAF's $10.4 billion project to acquire 126 "medium'' multi-role combat aircraft (MMRCA).

IAF, incidentally, has ordered only 20 Tejas till now, apprehensive as it is of its capabilities since the fighter's final operational clearance (FOC) will come only in December 2012 at the earliest.

Antony declared that high-level reviews of the Tejas project were being conducted regularly by IAF chief and deputy chief to ensure it's completed in time.

Hindustan Aeronautics Ltd, Aeronautical Development Agency and DRDO have, of course, faced a lot of flak for the huge delays.

Initiated as far back as 1983 at a cost of Rs 560 crore to replace ageing MiG-21s, the LCA project costs have now jumped to Rs 5,489 crore. The figure may well cross the Rs 10,000-crore mark by the time the fighter is fully ready.

IAF is certainly keeping its fingers crossed, grappling as it is with a depleting number of fighter squadrons, down to just 32 from a sanctioned strength of 39.5.

The force is banking upon the "air dominance'' Sukhoi-30MKI fighters, with 230 of them being contracted from Russia in deals worth around $8.5 billion, to fulfil its need for "heavy-weight'' fighters. The MMRCA will take care of the medium-weight category. Tejas, in turn, is slated to plug the light-weight fighter gap in the combat fleet.

Re: Light combat aircraft ' Tejas ' to get foreign engine.

Ha ha ha ha Why dont the incompetent idiots who are wasting money just buy it from US or someone who has this technology.

I firmly believe that except ISRO and BARC the rest of the organisations are just a waste of national resources. All those morons must be made to write COBOL code on some IBM mainframe project

Most of the times these kind of indegeneous and failed projects are fronts to get the main technology. Indian Corruption and inefficiency is well known in the world . Like Israel India being a Hindu country has no natural ally.

So India won't get transfer of technology so easily. So Government will pickup a project drag it for long,it will appear failed and cost overrun or over priced but behind the doors for same cost lot of other technology transfers will happen.

One example could be Waship Admiral Gorvachov. The cost is doubled but actually India is paying Russia for some other technology transfers which happened in parallel like Nuclear Submarine or some other things.

I may dislike Congress but I do Praise them for preventing India from becomming a global untouchable like Israel.

Thumbs down Re: Light combat aircraft ' Tejas ' to get foreign engine.

What a shame. We have been making hell lot of publicity to the world that we are developing an "indigenous fighter jet", and here we go end up as duds.
Time to liquidate these proven loosers called , DRDO and crap. Probably we start to engage our own private firms to develop them. Till our pvt. sector is strong enough to produce defense equipment , we should buy them from countries like US,Russia

Re: Light combat aircraft ' Tejas ' to get foreign engine.

Its an insult that engineers have written the above comments. sala how the hell do u guys think that with a funding of 500 Mil one can develop an engine with world class capabilities from scratch?????

Jaguar when it was brought to till date runs on an underpowered engine and no one bothers to discuss about that. But then if some indigenous one is underpowered then every one runs for its blood.

Its not just the govt that has to be blamed, after the marut fiasco when the first Indian Designed (tough designed by a german engineer) and built fighter was completed, GOI did not follow up with the follow on plane why??? not only that the engine that was designed for the plane was capable of going supersonic on dry thrust(so no usage of back burner, which is called cruising technology and which is an integral part of building a stealth plane), to which the chief of air force commented that it was an technology of no use, I am sure that ex air chief would be kicking himself in his balls for saying that sentence.

Maruts engine was capable of supercruise ......wow.....I didn't know that.......Thats a technology only the f22 has.

For those who dont understand ,normally a plane can go to supersonic speed by firing the afterburners of the engine it has.

That is , the engines throw a flame behind while accelerating.

However ,the flame can be easily detected on enemy radar and render the aircraft vulnerable to detection.

supercruise is the ability of the engine to go supersonic without firing the afterburner ......a difficult technology to master.

if afterburner is not fired while accelerating to supersonic speed , then no flame comes out from behind and hence the aircraft cannot be detected on enemy radar.

of course , a lot of other things go into making a stealth aircraft.....that is a aircraft undetectable on radar.

for example the aircrafts passive detection systems have to be powerful , as the aircraft cannot use its own radar.the moment it switches on its own radar , the radar emissons are picked up by enemy radar.

the aircrafts body also has to be so smoothly curved at every place where an angle has to be there so that the enemy radar waves do not bounce and go back to the enemy radar .

plus the aircraft has to have radar absorbent paint.

But I didn't know about the Marut having a supercruise capable engine.........

Yes ,the HF 24 Marut fighter cancellation being a stupid mistake by the air force........Yeah I know about that.......

That is something GTRE and DMRL should have told policy-makers when they were approached for this project

This is what everyone says..DRDO takes too much in itz platter which it cannot eat leave alone digest!!!

thats what i have been trying to say GOVT willing accepts Jaguar with under performing engines but then when it comes to Kaveri , DRDO is made to go through Hell. That too after paying 10 times more money for Jaguar engines than kaveri!!!!!!!!!!!!!!
