ADA Tejas (LCA) News and Discussions

[DefenceIndia]

Indian Defence Information

"We can adapt the LCA into becoming an advanced UCAV (unmanned combat aerial vehicle), not immediately, perhaps 10 years down the road."
-DRDO chief M Natarajan

He also says, "As a corollary to these developments, we can think of a twin-engined LCA of the 18-20 ton category, gradually developing a spectrum of products... We can think positively of the LCA replacing MiG-21s, then we can think of a futuristic MCA to replace certain number of squadrons of medium multirole combat aircraft, but with more advanced technologies."

Very first of its kind i guess.....

'Lockheed-Martin's Failure To Respond Has Affected Our Programme Schedule': LCA (Navy

Top officials associated with the Light Combat Aircraft naval variant (LCA-Navy) have confirmed to LiveFist that Lockheed-Martin's inability to obtain US State Department clearances to consult with the programme have introduced a "significant delay component" into the schedule of the first aircraft roll-out. In the next few days, ADE is likely to officially hire the services of EADS, which lost the original bid in 2009. When contacted about the development, Lockheed-Martin's India spokesperson John W Giese said, "Lockeed-Martin continues to work with the US government to support the Light Combat Aircraft program." Am still awaiting an EADS comment.

The LCA-Navy desperately needs the services of a technological consultant to tweak the platform's landing gear and arrestor hook design configuration and conduct an urgent audit of the work done so far -- in addition to helping solve some critical airframe weight issues.

"There are some issues which need to be dealt with before we can progress. We are at an advanced stage of discussions with EADS and are hoping to stick to our timeline as much as possible," an official said. As reported earlier on LiveFist, the LCA-Navy's first prototype looks forward to a roll out in two months time, followed by three months of rigorous ground tests for confidence. Time is now absolutely critical, and the ADE has set the latter half of December as a window for a possible first flight.

Why not Dassult or even MIG but EADS(with no carrier-born fighter in kitty) is notoriously confusing and even more gets added to it when ADA says they want some one to help tweak 'Landing Gear' and 'Tail Hook'.

I had talk with a Naval engineer deputed to ADA for N-LCA at this DEFXPO and he told me this "Tail Hook is new to us so we want an experience firm to look and say ok or if needed help". When asked further he said "tail hook is something which lands or touches deck prior to main landing gear and we want someone experienced to make us sure that hook will remain in deployed position after touching the deck" he adds "If Tail Hook get pushed up beyond desired angle then it will miss all three arresting wires"

[AJSINGH]

IAF Air Chief Marshall openly said that " I am not happy with LCA for the last 20 years "

 

[AJSINGH]

what are the specs of the Tejas MK-II ? in terms of engine thrust , avionics fit and sensors and will Mk-II fit IAF needs ?

Old news. Latest updates: AF HQ found MK-1 far more capable than Mig-21 Bis and have placed addition order for 20 MK-1 Tejas or one more squadron of Tejas MK-1...

what are the specs of the Tejas MK-II ? in terms of engine thrust , avionics fit and sensors and will Mk-II fit IAF needs ?

I had posted it on old LCA thread. If you get to you will see........

I am mentioning few i can recall
a. AESA with terrain mapping.
b. Inbuilt comprehensive EW package.
c. LO features.
d. Two way data link.

Only time can tell whether LCA is capable or not, only after the IOC and some use by pilots can the capabilities of any a/c be gauged so i guess until then we just have to wait and see

 

[AJSINGH]

i just want to see Tejas in active combat duty replacing the legendary Mig21 for point defense and are we developing ASEA radar on our own or is their any other collaborator ?

This logic is not true. You have to remember that LCA is India's own fighter and every second of its flight had IAF pilots at controls. Statistically speaking IAF is having plus 800 hours experience on LCA and this by no means inadequate time and also enough to know about most of its flying characteristics. Allow me to go so far to say that IAF knows about LCA's capability more than its designers. So for IAF IOC is nothing more than just a milestone...

What i meant to say was you can test a a/c for 1000hrs but nothing can test a a/c in real combat situation all the testing and results shown has been impressive but that is only in an prearranged environment please don't mistake the LCA is a good achivement and in any standerds it is equal to many a/c if not better but still let us remember even proven platforms like F-22 raptors,MiG-29,SU-30MKI had problems even after tests until it flies in IAF colours in its borders it is hard to tell its capabilites and morover till now it has only been flown by a hand full of experienced test pilots only the IAF needs simulators,and training jets to train its pilots

You can still check their capabilities in air force exercises. You don't have to go to war or fly at the border to know the capabilities of a fighter. Of course all fighters will have some technical/mechanical glitches as they fly and these can be alleviated over the years.

Tejas LSP-4 completes its successful maiden flight at HAL airport

Tejas LSP-4 maiden 40-minute flight successful; Grp Capt Suneet Krishna goes supersonic at first attempt

IOC WITHIN SIGHT! Final IAF configuration LCA LSP-4 maiden 40-minute flight successful; Grp Capt Suneet Krishna goes supersonic at first attempt; MMR, new avionics software, ECS, RWR all onboard

Tejas LSP-4 completes its successful maiden flight (above) at HAL airport in Bangalore on June 2. The flight lasted for 40 minutes. Gpr Capt Suneet Krishna piloted the aircraft. "This is fully equipped with IOC standards," says a thrilled ADA boss P.S. "More aircraft will join the fleet," says HAL chief Ashok Nayak. "We shall and we will," says Team NFTC.
The aircraft flew at an altitude of 11 km, went supersonic and touched 1.1 Mach speed with Test Director Gp Capt D. Chakravorty, guiding the pilot from the telemetry facility of NFTC. A chase aircraft was flown by the Chief Test Pilot of NFTC Gp Capt RR Tyagi with Wg Cdr Prabhu as the Test Director. The test flight was supervised by Air Cmde Rohit Varma, the Project Director (Flight Test) at NFTC. The flight was also witnessed by Cmde BS Prahar, NM who is the ACNS (Air) at Naval HQ. The Indian Navy has a considerable stake in the programme, as they look to replace their Sea Harrier fleet, which is due to be phased out in due course.

so here it goes great news indeed for LCA

 

[Rahul Singh]

After LSP-3's first flight, when it was reported that LSP-4 will follow in a month and half i had little to believe but now i can say ADA has finally grown up to a level as far as LCA is concerned to meet schedules.

Kudos to ADA and DRDO....
