HAL Tejas | Updates, News & Discussions

[duhastmish]

That's the best sign of good news i heard in ages coming from D.R.D.O, I would love to see my bird flying in skies. go LCA. its not just a machine but so many Indian hopes are hanging on it.
Still the greatest day for Indian defense will be the day we will fly L.C.A with our own AESA And kaveri fitted. I hope the day is not too far away.

ADA plans to develop medium combat aircraft with IAF

ADA plans to develop medium combat aircraft with IAF

Bangalore, Feb 03: Aeronautical Development Agency, a Defence Research & Development Organisation (DRDO) lab, plans to design and develop a medium combat aircraft with "stealth features" in partnership with Indian Air Force, an ADA official said on Tuesday.

"We are working with (Indian) Air Force as to what their requirement is", ADA Director P S Subramanyam told PTI here.

"They (IAF) are also coming forward to evolve the specifications of medium combat aircraft...what we call next generation fighter aircraft," Subramanyam said.

He said it would be in the 20-tonne category, twin-engine aircraft, likely to be powered by the Kaveri-Snecma engine. "It will have stealth features," he said.

"It's going to be a joint activity (between ADA and IAF) from beginning", Subramanyam said, adding "it's good that even Air Force is also feeling that we should take up this programme".

Meanwhile, he also said the Light Combat Aircraft Tejas has started flying with weapons, and integration of radars would be completed by next month.

"Once I do that, more or less system development activity (of LCA-Tejas) is completed", he added.

domain-b.com : EADS to join LCA programme; agreement in next three months

EADS to join LCA programme; agreement in next three months news
03 February 2009

New Delhi: In an attempt to speed up some aspects of the LCA programme, India is likely to offer European consortium EADS a $20 million contract to provide technical help in the flight trials of the indigenous Light Combat Aircraft (LCA) programme. Even as reports in the media suggest that the deal may be signed during the forthcoming AeroIndia 2009 air show, commencing 11 February at Yelahanka, Bangalore. DRDO sources suggested very likely the deal could be inked sometime over the next three months.

Technical and commercial bids for the deal had been invited from EADS, Saab of Sweden, Dassault of France, Boeing and Lockheed Martin of the United States, and MiG Corp. of Russia.

Through the deal DRDO's Aeronautical Development Agency expects the shortlisted company, in this case EADS, to help speed the LCA's flight testing through its initial operational clearance (IOC) and final operational clearance (FOC) phases.

The areas of cooperation could include flight envelope expansion; testing for high angle of attack; aero database validation; external stores carriage with emphasis on stores separation; wake modeling and penetration flight tests; and refinements to existing simulation models.

The LCA programme is currently entering the weapons integration stage and the first lot of aircraft are expected to be inducted into the Indian Air Force (IAF) by 2010. The IAF has ordered 20 of these aircraft in the initial phase.

DRDO expects to achieve initial operational clearance with the help of a indigenously developed multimode radar integrated with a weapons suite. It is estimated that FOC could take three years, and an additional 1,500 hours of flight testing, to achieve.

The LCA is a single-seat, single-engine, supersonic multirole air superiority fighter jet of the fourth generation.

With international engines, DRDO fast-tracks LCA project
4 Feb 2009, 0043 hrs IST, TNN

Bangalore : All doubts raised over LCA being a key fighter aircraft for India owing to delay in the Kaveri engine can be put to rest.
The LCA will fly - and fly on international engines initially. DRDO has decided that Kaveri engine will not be a hindering factor in India showing off the lightest jet fighter.

M Natarajan, scientific adviser to defence minister A K Antony, has publicly spelt out DRDO's determination to fly the LCA in time for the IAF, even if on international engines in the first few squadrons.

At an Aero India press conference on Tuesday, ADA director P S Subramanyam, said: "I am confident that DRDO will keep to the December 2010 initial operational clearance (IOC) plan. We have started weapons testing on the LCA, and soon the aircraft will fly with the hi-tech MMR radar."

"We can do a few things with the Kaveri engine and fly the LCA no doubt. But that's not the point. There are new specifications and it will take time to meet those. Most of the work with existing specifications is over, but we're working on more complex aspects.

"Meanwhile, we understand the IAF has tight induction bands and we will get the LCA into those bands. The first two squadrons will fly on GE engines and the next four will fly on any international engine that qualifies our new request for proposals.

"The Kaveri engine will take another five years given the new specifications. Engine development is not the easiest of things and no one is going to share technology on the platter.Meanwhile we will keep to IAF requirements," Subramanyam explained.

What this means is operations of the first six LCA squadrons are taken care of -- around 90 aircraft. To a large extent, the aircraft is indigenous and all that would be left would be the engine. The flight path of the LCA seems clear after the go-ahead for international engines.

LCA why you don't put the link with the news item?

link is here: With international engines, DRDO fast-tracks LCA project-Bangalore-Cities-The Times of India

So totally plan is for 6 squadrons even Air Chief has also indicated in this direction.

Good news indeed.

Awsome news, I cant wait to see our own bird fly over Indian sky. Might use foreign wings(engine) at frist but oh well.

 

[LCA]

As it look like MMR will finally get integrated with LCA, which mean its A2G problem get sorted out.

MMR is based on pulse-doppler technology.

some people think it is a outdated technology,may be true.

but this technology still in use in many aircraft

Here is the list of using pulse doppler radar:

F-16 A/B,which pakistan have.

F-16 Fighting Falcon - Wikipedia, the free encyclopedia

Typhoon.(Current version)

Euroradar CAPTOR - Wikipedia, the free encyclopedia

SaaB gripen(Current Version)

JAS 39 Gripen - Wikipedia, the free encyclopedia

Mig-29

Mikoyan MiG-29 - Wikipedia, the free encyclopedia

etc,etc

Details of MMR shall be cleared after test

 

[LCA]

specs looks good even batter than jf 17 but still think there should be some prob as IAF don't want to buy it.

hi buddy, i think you have the same problem,which aamir khan have in gajni.

Please read this may be you remember something.

[BATMAN]

BATMAN, I don't understand how you reached the conclusion that "airframe change" will be needed?

I don't think EADS has been invited to help in suggesting the required engine power?
Can you please, tell us the g levels of LCA?
How do you think angle of attack can be improved without making any alterations in airframe?

On the otherhand DRDO is claiming that they have met the given design parameters of IAF, than why is it a problem to induct LCA in its present form?

Can you post the parameters of LCA in its present form?

Hi buddy, LCA deficiencies are not limited to engine.
So please, don't try to mislead us by repitative post blaming the failure on delay of Kaveri.
Even if Kaveri would have been ready today it cannot be better than GE engine.
Problems are in overall design.

Awsome news, I cant wait to see our own bird fly over Indian sky. Might use foreign wings(engine) at frist but oh well.

EADS invitation was just a reality check.
FYI, foriegn element is not limited to engine alone!
Whole LCA is a product of foreign hand.

Swadeshi LCA has US engine, Israeli, Swedish avionics, Italian wings

India’s ‘indigenous’ LCA comes with an American engine, on wing panels imported from Italy and avionics, navigational aids and radars from France, Israel and Sweden.

‘‘An aircraft has three major components. An engine, airframe and avionics. The GE-F 404 engine is American, most avionics like radars, INGPS, electronic warfare equipment, radar altometre, the fly-by-wire system, ground-mapping system and other pilot-support system are all imported from Israel, France and Sweden. Even the airframe is not entirely Indian. The composite wings have been imported from Italy. What is creditable is the integration of such complex systems,’’ sources in the IAF said.

While Air Chief Marshal A Y Tipnis urged IAF not to swing from acute scepticism to euphoria after the first flight early last month, his predecessor Air Chief Marshal S K Sareen said that the indigenous components in the LCA were few. ‘‘Only 30 per cent of the airframe is Indian, the fly-by-wire control, avionics and engine are not ours,’’ he said. ‘‘So who are we fooling by saying that 70 per cent of the LCA is indigenous,’’ he asks, while crediting the scientists with effective system integration.

The Ministry of Defence (MoD) claims that almost 70 per cent of the aircraft, including the tyres, tubes, brakes, part of avionics and airframe are indigenous. British Aerospace were consultants to the development of LCA.

India-US Defense Technology Cooperation identifies three 'Mission Areas' (i) Aircraft Technology, (ii) Third generation anti-tank systems and (iii) Instrumentation of test sites and manpower training. Under Aircraft Technology, there has been a substantial amount of cooperation and technology transfer for the Light Combat Aircraft (LCA) which is a major area of activity. An India -US Technical Advisory Group (TAG) is in place for monitoring the Technology Transfer between the US and India on the LCA.
