Negotiations for Tejas aircraft engines soon​

​

​

​

The Aeronautical Development Agency (ADA) is set to start commercial negotiations with aircraft engine makers Eurojet Turbo GmbH and General Electric Aviation for 99 aircraft engines for the Light Combat Aircraft (LCA) Tejas.

The two engine manufacturers had been shortlisted after expressions of interest for an alternate engine for the LCA were issued last year. Eurojet, a European consortium, is offering its EJ200 engine, which powers the Eurofighter Typhoon fighter plane while the American firm has put in bids for its GE F414 engine used in the Boeing F/A-18 E/F Superhornet. The new engine will power the Mark II variant of the Tejas, which currently runs on F-404 engines made by GE.

“Soon, we should be starting commercial negotiations, probably in a couple of weeks,” said PS Subramanyam, director, ADA. “The technical evaluation is over. I think both of them (companies) are good candidates.” The Tejas aircraft ,with its current engine and configuration, is expected to be inducted into the Indian Air Force (IAF) from March next year with state-run military plane maker Hindustan Aeronautics Ltd supplying 20 planes initially. The proposal for a second batch of 20 planes has been cleared by the defence ministry and negotiations are on, Subramanyam said.

The IAF has indicated the need for five squadrons of the Mark-II, which will feature the alternate, more powerful engine and upgraded electronics. “Wherever there is obsolescence setting in, in terms of advancement of electronics, we are going for state-of-the-art electronics in the Mark-II,” said Subramanyam. Even as the process of procurement of engines is on, ADA has begun two tracks of design based on the shortlisted engines so as to not lose time, he added. Meanwhile, a proposal by the Defence Research and Development Organisation (DRDO) to co-develop the indigenous Kaveri engine with French engine house Snecma, is under consideration.

An upgraded and more powerful Kaveri engine is being seen initially as a replacement engine for the first batch of Tejas aircraft, Subramanyam added.

“Every aircraft in its lifetime needs two replacements. Some of those engines are already looking for that. By the time Kaveri gets developed and demonstrated, those engines can start coming as replacement engines for the first 20, 40 (aircraft),” he said. “There is full scope of what their profile is. It is very clear in our mind. The Kaveri engine profile for the next 30 years has a very strong dovetailing into the LCA programme,” he added.

Eurojet offers dual-use engine for LCA​

Eager to join hands with the Defence Research and Development Organisation (DRDO) and its associates in the development of India's Light Combat Aircraft ‘Tejas-Mark II,' the Eurojet consortium is offering its engine that could be tweaked to work on its naval version.

“We are offering two variants of the EJ200, bidding for the India's LCA Mark-II which can be altered through a software change to suit the requirements for the naval version of the LCA,” Eurojet Vice-President Sales Paul Hermann told a group of journalists here.

The Aeronautical Defence Agency (ADA), the nodal agency for the design and development of the LCA under the overall supervision of the DRDO, had sought a proposal from the EJ200 and the American GE414 engine. The order will be initially for 99 engines with 10 of these in ready-to-use condition. There is an option for additional 49 engines order.

Eurojet Chief Engineer Wolfgang Sterr said there were over 1,500 EJ200 engines for the 700-plus Eurofighter Typhoon aircraft under contract to six nations. He said the engine was suitable for the LCA and could be used for the naval variant that the ADA was working on.

The Eurofighter is in the race for the 126 Medium Multi-Role Combat Aircraft that the IAF is acquiring.

The naval version requirement of greater thrust for take-off from an aircraft carrier can be met without altering the hardware of the engine. With a switch of software the EJ200 can be used for the naval variant and vice-versa.

While the company preferred not to make any direct comment on the price tag, EJ Sales Director Adrian Johnson, said it would be competitive in many aspects through low life cycle costs, transfer of technology and offering partnership to India for future development and enhancement of the engine and its systems.

The officials said, “If the Eurojet makes the grade, the organisation could also share its expertise in India's quest to develop indigenous Kaveri engine. We have experienced the challenge India is facing, At Rolls-Royce, it took us 100 years to get where we are…,”Mr. Johnson said.

The Eurojet consortium includes Rolls-Royce (England), MTU (German), ITP (Spain) and Avio (Italy).

Naval LCA to roll out on July 6​

The first Naval Light Combat Aircraft is scheduled to roll out from HAL ARDC design hangar here on July 6.

The LCA (Navy) is the first indigenous effort to build a complete air element for the Indian Navy. The aircraft is fitted with the GE-F-404-IN20 engine and is specifically designed for ski jump take off and arrested landing, with high landing loads compared to its Air Force counterpart. By initiating this venture and fostering it, the country has shown great confidence in the competence of its scientists and engineers, an official release here said. Chief of Naval Staff Admiral Nirmal Verma will be the chief guest at the function that is expected to be attended by senior officials of PSUs, private industries and institutions which have supported the programme during its development phase.

Checking phase

The event ‘roll-out' is a significant milestone when the aircraft is brought out of the building hangar (where the aircraft is actually assembled part by part), declaring that it is ready to undergo the phase of systems integration tests leading to ground runs, taxi trials and flights. “The main aim of LCA (Navy) NP1 and its Fighter Counterpart (NP2) is to prove itself with its technologies incorporated as a formidable platform, and to be a suitable replacement to the aging fleet of Sea Harriers at a later date in a derivative MK2 configuration, with a higher thrust engine and optimised mass.

This aircraft, with considerable technology and punch for years to come, is being designed to operate from the future indigenous aircraft carriers the Navy plans to acquire,” the release added

The formal sanction by the Government for the programme was accorded in 2003. The first stage of development includes design and fabrication of one trainer and one fighter, NP1 and NP2 respectively, along with a Shore Based Test Facility (SBTF) at Goa, to simulate carrier take off and arrested landing. One of its kind

The LCA (Navy) is the only carrier borne aircraft in the light category, and there are no other aircraft worldwide, the release said. The aircraft will be operating with a wide variety of operational role equipment, such as the BVR missile, anti-ship missiles, conventional bombs, air defence guns, CCM's and drop tanks.

A Humble questions to all Senior members-- will MK-II have AESA or, DRDO developed MMR radar..because in some other forum a very senior member is saying AESA will only come in MK-III , while other is saying it will be AESA on MK-II.

sry i'm not a senior member member but still answering ur ques ........

tejas mk2 will be carrying an aesa radar that will be a jv between drdo and a international company(which has not been chosen yet) that has exp in making aesa radar.....

and also currently there no tejas mk3 in sight !!!

will MK-II have AESA or, DRDO developed MMR

so actually it will be a mix of both ie drdo (jv) developed aesa.....

LRDE is working On Miniaturization of AESA radar for LCA tejas, as per the Latest News on LCA radars, There is an Active AESA radar program going on for the LCA mk2....

 

[sameersay20007]

please tell me the difference in pesa radar and aesa radar

 

[flanker143]

please tell me the difference in pesa radar and aesa radar

Google it buddy , u will get better and detailed info........ also this is a lca thread !!!

plz don mind it .....

There is, but reports mentioned, that IAF rejected it, because it is not good enough. That's actually not even surprising if we keep in mind how MMR, or DRDO AWACS development are going on. So teaming up with an experienced partner is the right decision, but it came way too late!

please tell me the difference in pesa radar and aesa radar

This should help too:

Be fair mate, he is new and you asked a lot of questions in different threads too right?
