IAF pilots can fly Tejas on Dec. 27


IAF pilots can fly Tejas on Dec. 27

Combat pilots o of the Indian Air Force (IAF) can look forward to flying the "Made in India" fighter Tejas on December 27.

The indigenous Light Combat Aircraft (LCA) will get the critical thumbs up sign in terms of safety and reliability or "initial operational clearance" (IOC) from experts. This approval will lead to the induction of the fighter into the IAF's fleet, marking a major milestone for the Indian defence industry, Mr P.S. Subramanyam, Director, Aeronautical Development Agency (ADA), the man spearheading the pro

gramme, told this newspaper. The IAF has ordered for 40 of these combat jets (two squadrons) which will be deployed at the air force base in Sulur, Tamil Nadu.

In addition to initial operational clearance of the Air Force version, the programme will witness another high point: with maiden flight of Naval version of Tejas in December 2010.

Mr Subramanyam said: "The campaign of certification is on and all organisations involved in the programme are working to complete the process by the targeted date. Once the certification is over, it will go to the user, and that will be major milestone for the programme."

India Sets Dec. 27 Deadline For Tejas IOC | AVIATION WEEK
..................................

The LCA chief said that an additional 20 Tejas aircraft are on the way, bringing the total to 40. The first 40 will be MK-1s, while the next 86 will be Mk-2s, with a new powerplant. The Indian navy is projected to receive 56 of the aircraft, while 16 trainers also will be delivered.

Sources say the limited series production vehicle (LSP-5) is expected to fly very soon, with the LSP-6 (an experimental platform), LSP-7 and LSP-8 following suit.

"The engine ground run for LSP-5 is over, and we may conduct the first flight after sorting out some last-minute teething issues," a source said.

Indian LCA Undergoing Sea Trials

India's Tejas Light Combat Aircraft is currently undergoing sea trials at NAS Hansa, at Dabolim in Goa.

This is part of Tejas's out-of-station flight-test plan, with pilots from the Bengaluru-based National flight Test Center performing high angle-of-attack (AOA) maneuvers.

A source tells AVIATION WEEK that Tejas will undergo parameter identification (PID) and sea-level flutter vibration tests, with an all-external stores (bombs, fuel tanks, missiles) configuration.

"The PID is done [with] latest software version of the digital flight control computer being developed by the Aeronautical Development Establishment," the source says. "There are many system integration checks and weapon modes to be tested. We need to check some more sea-level performance points in high-AOA mode."

The Tejas took part in earlier trials at NAS Hansa, during which it fired a missile, and will undergo extensive weapon testing next month. A large contingent of engineers, scientists, pilots and ground crew are in Goa for the trials, which will continue until next week.

Five Tejas aircraft from the flight line are expected to participate in the sea trials.

"Radar assessment at sea level for air-to-air and air-to-sea mode will also be tested," the source says. "The Tejas will be flown at different altitudes and Mach numbers, while the flutter test will be done with various external configurations."

The trials are critical for the Tejas program, which is moving toward completing all pre-initial operational clearance requirements.

Eurojet pips GE in LCA engine bid

Ajai Shukla / New Delhi September 20, 2010, 23:35 IST

Europe has an edge over the US in the tightly-fought contest to sell India a next-generation engine for the homegrown Tejas light combat aircraft (LCA). Informed sources have told Business Standard that when the bids were opened last week, European consortium Eurojet bid $666 million for 99 EJ200 engines, against US rival General Electric, which quoted $822 million.

Both engines had been earlier adjudged technically suitable to power the Tejas Mark-II. Therefore, according to the ministry of defence's procurement rules, the vendor offering the lower price is to be handed the contract.

But the champagne corks aren't popping yet at Eurojet. Both engine-makers have been asked for certain clarifications by Wednesday, and senior Eurojet executives are worried that Washington could pressure New Delhi to opt for the US engine in the interregnum.
At stake here is far more than a few hundred million dollars. Industry experts say India's choice of engine for the Tejas would significantly shape the choice of a medium multi-role combat aircraft (MMRCA), an $11-billion contract for which the Indian Air Force is evaluating six fighters. Of these, the Eurofighter has twin EJ-200 engines, while GE F-414 engines power the US-built F/A-18 and Sweden's Gripen NG fighters.

Says Air Vice Marshall (Retd) Kapil Kak of the Centre for Air Power Studies, the IAF's official think tank, "It is as clear as daylight. Selecting the EJ200 for the Tejas would boost the Eurofighter's prospects in the MMRCA contest."

"Its engines, which form about 15-20 per cent of the cost of a modern fighter, would be already manufactured in India for the Tejas. For the same reason, rejecting the GE F-414 would diminish the chances of the two fighters that fly with that engine," he added.

In its tender for the Tejas engine, the defence ministry has specified that only ten engines could be built abroad. All subsequent engines must be built in India, with the vendor transferring technology for their manufacture. If the EJ200 were built in India for the Tejas, Eurofighter would benefit from a fully amortised engine line and also be entitled to offset credits for the 'made-in-India' Eurofighter EJ200 engines. This would lower the price of the Eurofighter — a huge advantage for an aircraft regarded as high performance, but expensive. Logistically, too, the IAF would prefer an MMRCA with engines that were already in its inventory.

Selection of the GE F-414 engine, on the other hand, would provide all these advantages to the vendors of the F/A-18 and the Gripen NG fighters. This is a key reason why Eurojet and GE have conducted their Tejas engine campaign so competitively.

Furthermore, the order for 99 engines for the Tejas Mark-II is just a foot in the door to the Indian market. Given that each fighter goes through two to three engines during its operational lifetime, the four to five planned squadrons (84-105 fighters) of the Tejas Mark-II would actually need 200-300 new engines. The 126 MMRCAs could use several hundred more.

Business Standard had earlier reported on the European aerospace industry's plan to enhance its presence in India's military programmes through Eurofighter and the MMRCA contest. The first move by EADS was to provide consultancy to accelerate flight-testing of the Tejas; now comes the second move: bidding aggressively to win the Tejas engine contract.

Defence ministry sources have expressed surprise that Eurojet bid 20 per cent cheaper than rival General Electric, which is widely regarded as a cost-effective manufacturer. In fact, conversations with EADS executives reveal that this is a well-considered business strategy.

Sources in the Aeronautical Development Agency confirm that both GE and Eurojet engines fully met the technical requirements to power the Tejas Mark-II. The EJ200 — which IAF favours — is the more modern, lighter and flexible engine with greater potential for growth. The GE F-414 is heavier, but provides a little more power.

Eurojet is a consortium between Avio (Italy), ITP (Spain), MTU Aero Engines (Germany) and Rolls-Royce (UK), which was set up to develop the EJ200 engine for the Eurofighter. It is headquartered in Hallbergmoos, Germany.

Powering LCA Mk-2: GE F-414 vs EJ-200; talks shift to Delhi; decision soon:emot158:

Tarmak007 -- An Indian Defence blog with a difference: Powering LCA Mk-2: GE F-414 vs EJ-200; talks shift to Delhi; decision soon

After months of extended analysis, comparison studies, and calculations, the hunt for a suitable engine for Tejas Mk-II seems to have reached the final phase. The contenders -- GE F-414 and EJ-200 -- are equally confident that they would make it to India's Tejas.
MoD sources confirm that the negotiations have now shifted to Delhi (from Bangalore) and there are couple of issues need to be sorted out. All top officials associated with the project have now reached Delhi on Sunday night and the next two days might be crucial. The Tejas is currently undergoing sea-trials in Goa.
A section of Indian media have been reporting for the last one month that EJ-200 is/will be the likely choice, but MoD sources refuse to say anything official yet. "We are continuing the talks from today," an official said.
Stay tuned for the latest.

Let me remind all here, who think LCA is a dog-fighter..
LCA was deigned based on Mirage-2000, Back in days IAF demand was a supersonic interceptor with BVR..
Mirage 2000 was a good long range interceptor during 80s and Mig-29 was a dog-fighter..
therefore the deign of LCA of today is good also it gives more than just being a interceptor..
though i do agree abt its low powered engines...

If you change the engine the whole frame will have to be changed.. As far as I know, can be f 414 fitted on this platform but Euro jet 200 will need some some modifications...

Its the other way round. GE engine fitting will need more modifications to LCA while Eurojet fitting will need very minor modifications.

 

[Yusuf]

the dia of the 414 is bigger than the EJ.. os if at all any engine warrants a change in LCA design, its going to be the 414.

But with Obama coming over, never know what will happen. They are yet to find a BIG impact thing for the visit.

Diameter of both F404 and F414 is 889 mm and EJ200 is 737mm. So LCA do not need any structural changes for F414 and EJ200 might need some.

But with the advantages EJ200 have over F414, MoD should choose EJ200.

there was no surprise indeed , but the fect of the matter is that in every Govt-to-Govt deals india paying more to US ....

 

[Rama]

US can never be trusted with the LCA project as they have tried to shut it down few times.The fact that they supplied India with F404 engine does not mean that they were in favor of the project. 2 years ago they prevented Boing from offering consultancy on a LSA testing program. And before this, they refuse to allow other American companies to verify the fly by wire controls laws to validate the flight control system. Purchase of American F414 engine would cripple India in the time of crisis. I do not see America standing by India in any conflicts that may be imposed on India by its neighbor. Let American prove its worthiness on non-critical defense technology before India should entrust them with either the LCA project or more importantly the pending purchase of multi role combat aircraft.Trust has to be earn and until they do so, be careful.

BUZZ: Eurojet Throttles Up For Tejas?

There's a lot of buzz over the Tejas Mk-II engine competition, with a flurry of reports suggesting that the Eurojet EJ200 is positioned to win the deal, and not close competitor General Electric with its F-414-400. The connection between the Tejas Mk-2 engine and the MMRCA is inevitable, so first, let's get a couple of things out of the way as far as the Mk-2 question is concerned. Both the F-414 and EJ200 were equally compliant with the qualitative requirements of the Indian Air Force. Second, despite what either of the companies has said, there's a good deal of modification that both engines will require for integration with the Tejas -- both engines are dimensionally different too, with one short and stubby and the other longer and more slender.

Both engine makers promise that they can modify their engines for the Tejas and complete certification in two years or less from the time of contract signing. For example, when I visited Eurojet headquarters near Munich in January, the company's managing director Hartmut Tenter said, "There will be some changes to the mounting assembly, a different hydraulic pump and an additional generator pack. In addition, engine interfaces might' need changes depending on how the LCA is configured. But we are confident of having a fully certified engine ready in less than two years."

Both engine houses have been known to claim that the Tejas airframe will require no airframe changes for the new engine. Untrue. The Indian Air Force and HAL have both confirmed that the selection of either of the two engines will mean minor -- but not negligible -- changes to intake architecture, aft fuselage and engine interface structures on the Tejas airframe. How long that will take is a good question.

According to sources, GE's pitch -- technology and offsets aside -- has been underscored by the experience of the F-404, variants of which currently power the Tejas Mk-1. The company has also thought of the F-414 for the Tejas well before it was officially decided that a new engine would power the Mk-2. Eurojet, on the other hand, has pitched the EJ200 with the very tempting notion of a dedicated EJ200 global production line in India, along with true qualitative technology transfer, that will include single crystal technology to HAL and GTRE.

But none of this may actually matter now, since both engines have performed well and met all or at least most requirements, and have an approximately equal level of compliance.

recall just prior to deciding the future of arjun tanks based on comparative trails between arjun and t90, it was ajai shukla who was making all the leaks and how good arjun had performed (though then i had written him off) which was an attempt to scuttle any move by the IA to not order any further arjuns, this one sounds just the same to make sure the americans dont get a chance to sabotage this one and these last minute clarifications dont sound too encouraging to me, hope ajai like last time has out smarted the MoD.
