ADA Tejas (LCA) News and Discussions

[enlightened1]

great find E1.

i have always beleived LCA mark 2, considering its potential, will turn out into a very capable multi role fighter in the light - medium category. with a higher thrust engine up in its belly it will be capable of more payload. being delta wing has a natural high lift and with bigger wings will only accentuate it besides adding more hard points.

my gut is that it will eventually replace the mirages and possibly mig 29's as and when they retire.

time is still there so it is worth the effort.

Initially, Tejas will be used as an interceptor, which means that while the SU-30s & Mig-29s are providing fighter escort for the Mirages, Jaguars & Mig-27s in enemy territory or to the Phalcons & the tankers in India, Tejas will stay at home to welcome the bandits. Now that list includes F-16s, J-10s & J-11s...so you can expect the Mark 2 to be quite a piece of work. I don't think the IAF will settle for anything less...& yes it will eventually take over from the M2K & the Fulcrums both of which are scheduled to undergo life extending upgrades.

Not Abandoned N-Tejas yet

Already posted this in naval mrca but still...

Recently Indian Navy issued Request for information (RFI) for the purchase of undisclosed numbers of Multi role Fighter which it wants to purchase for its Second Indigenous Aircraft carrier which will be built in India and will join Indian Navy by 2018. In December Mig-29K started arriving in India in semi -knocked down condition which was purchased for INS Vikramaditya, reports suggests that Indian Navy may order more Mig-29K for First Indigenous Aircraft carrier also .But recent development of purchase of second line of New Naval Fighter jet has been blamed in largely blamed by many sections of media on delays faced by the countries Indigenous Naval Tejas Project. Highly placed source based in Goa’s Naval Air Wing has confirmed (lca-tejas.org) that Indian Navy has not abandoned Naval Variant of Tejas yet and are actually very much interested in the project its self, they has been confirmation that Navy is interested in getting N-Tejas with High powered engines which Air force wants for Tejas MK-II rather then the Currently powered engines of GE. Indian Navy wants to maintain around 150 Naval Fighter aircrafts by 2020 for Carrier and Land Based operations, Navy is no hurry in Procurement of Naval Tejas since India’s first Indigenous Aircraft carrier will be operational only by 2014 at best and Navy want best of the Tejas Project .Navy also will be building a Carrier type deck close to Naval Base INS Hansa where Carrier takeoff and landing will be simulated for Training of Future pilots of Indian Navy , First Prototype of NP-1 a Naval Tejas will make to air by end of 2010 and will also be based in INS Hansa for carrying out all necessary test to get clearance for Carrier operations , NP-1 will have design similarities with recently test flown PV-5 which is a Air force Trainer variant .

Mission that you have describe above for LCA has become obsolete the moment IAF gave its impression of having all the upcoming fighter jets in IAF to have a multi role capability. It depends upon in which theatre you are fighting a war and if conflict erupt in the locality were Tejas squadran has deployed then IAF will not wait for MKI and all other Mirage to arrive and deal with contigency at hand. Tejas has been conceived keeping in mind somewhere around having a mission capability of Mirage-2000 in the IAF in which Tejas will have to optimize its strength to do precision attack.

If point defence was the case then we may have hundreds of Mig-29s serving in various squadrans of IAF.

I said initially...of course all this will change once the M-MRCAs are inducted in significant numbers.

There is nothing anything intially mate, IAF is very strict in all this mission planning and they need aircraft which has ability to do the multirole mission planning right from the day one. I don't think arrival of MRCA has nothing to do with LCA for its mission role.

I never doubted the LCA's multirole capability...I'm talking about the first squadon to be based in the south..would you expect them to go on strike missions in Pakistan or doing CAPs near FOBs? Meanwhile the number of aircrafts continues to decrease.

Anywhere you base LCA, but primary use will the same which was first conceived during its inception. Even during 1965 and 1971 wars, many Canaberra's were sitting in the southwest, Eastern theatre, but call of the duty at war made them to get mobilize towards forward bases near the border. And yes Aerial refulling has made distance illogical in modern battlefield.

Technology to aid missile-satellite link

Asked about the progress in the naval version of the light combat aircraft, Saraswat said the first flight of naval LCA was expected in 2011.

Along with imported MiG 29 K, the naval LCA is expected to be the mainstay aircraft on board the Indian Aircraft Carrier, under construction in Cochin shipyard. But though the IAC is likely to join the navy by 2014-15, it’s not certain if the DRDO would be able to deliver the naval LCA in time.

Saraswat claimed that the recent successful flight of the LCA trainer version in Bangalore is an important step towards realising the naval LCA as the naval version will also have two pilots unlike the single pilot version for the air force.

The naval LCA, being assembled at the moment, will have ski-jump facility so that it will be launched from the decks of the carrier.

The top brass is seriously delaying the LCA project because of its engines. already its been decided to choose either of ej200 or ge 414.
ge 414 seems to be ideal choice since lca design is based on ge 404. choosing ej200 means changing design which results in more delays

assuming the lca and mmrca fighter have 2 different engines , i dont think its gonna be expensive it terms of maintenance and it will be surely affordable.

the top brass shud have chosen the best engine months back irrespective of the outcome of the mmrca to avoid delays in production and induction.

some good news:

Kill vehicle, a critical aspect: Saraswat

.
The engine had performed exceedingly well in high-altitude tests in Russia

You are telling it the other way. EJ200 does not require any significant structural change for current LCA whereas GE 404 is bigger than the existing frame can accommodate.

Eurojet Bolsters Engine Offer for India's LCA


By vivek raghuvanshi
Published: 4 Jan 2010 13:22


NEW DELHI - Eurojet of Germany has offered India aircraft engine technology to power India's homegrown Light Combat Aircraft (LCA) Mk2 version.

Indian Defence Ministry sources said the single crystal turbine blade technology, originally denied to Indian scientists, has been offered to India by Eurojet via the EJ200 engine. The EJ200 is competing with the General Electric GE 414 to power the LCA.


Last year, India's Aeronautical Development Agency, which is developing the LCA, floated a request for proposals to GE and Eurojet.

Meanwhile, EADS, whose Eurofighter aircraft is also competing for India's $10 billion program to purchase 126 Medium Multirole Combat Aircraft, has offered thrust-vectoring technology.

Indian Defence Ministry sources said the offer by Eurojet and EADS were received simultaneously last month.

An EADS executive claimed that equipping the twin-engine Typhoon's engines with thrust vectoring nozzles could reduce fuel burn on a typical mission by up to 5 percent while increasing available thrust in supersonic cruise by up to 7 percent.

I find it very difficult to believe that they actually want to impart with the single crystal blade tech.

 

[dineshchaturvedi]

When are we going to finalize on this?

 

[ppgj]

I find it very difficult to believe that they actually want to impart with the single crystal blade tech.

india is already working on this. must be close to mastering it. this is normal for west including US, that when india is close to mastering something - they offer the relevant tech. it has 2 aims -

1. stops india midway from mastery.
2. and they get the booty and ofc royalty.

two instances underline this.

one is american patriot offer to scuttle india's BMD.

another instance is when germans refused india special steel used in missiles. india mastered and developed it indigenously. when germans came back to offer drdo ticked them off infact by a counter offer to export the same to them!!

posting it again:

Shape Memory Alloys

Currently, the technology for the manufacture of Ni-Ti-Fe alloys and heat shrinkable sleeves are under transfer to Foundry & Forge Division of HAL, Bengaluru, where a plant dedicated to this purpose is being set up. When operational, this plant will be the only one in the country and amongst a few worldwide that manufacture shape memory alloys and heat shrinkable fasteners. Other components currently under development for application in LCA include heat shrinkable hydraulic coupling and thermally actuated valves.

 

[SATISH]

Well I guess Saraswat has cleared everything about Kaveri when he told that it is intended to to be used in the MCA. I think LCA using Kaveri is actually a test bed for the engine.

Satish, it was know from the very start that MCA will have two Kaveri engines, now that kaveri is taking very long time then expected, it is but natural that same should now be utilized for MCA, but i will rather like to see Kaveri with super cruise ability for MCA (call it Kaveri-II) if you want to make MCA true 5th Generation fighter.

Does anybody else finds it interesting that this eurojet offer comes just days after snecma announces complete tech transfer in case of kaveri.......

these europeans think they are too smart , offering us something we have already made a deal for...

obviously europeans are concerned. schema is helping us with kaveri engine problems along with tot . if the engine is ready soon we may not even need to buy the 99 engines contract of ge414 or ej200.

hence europeans offering us help. they are opportunistic , they could have offered to help us earlier.
