HAL Tejas | Updates, News & Discussions

[Abingdonboy]

Some fine days, i'll share couple of pics with you; then you'll yourself come to know where I saw it. Don't want to talk about it here.

I look foreword to that day then

Those hangers are located in Old Airport , Bangalore.

They're adjacent to the runway. But the area belongs to HAL, not the airport. The opposite side of the runway, incidentally, belongs to Centre for Air-Borne Systems(CABS), the DRDO lab responsible for our AEW&C systems.

SP-1 and SP-2 delivery by the end of this month?

LCA Navy Will Long Remain Work in Progress



A Shore Based Test Facility (SBTF) for simulating STOBAR (Ski-jump Take-Off, But Arrested Recover) operations from the deck of an aircraft carrier has been operational for a while in Goa and is due to be formally commissioned later this month. The SBTF is already being used to train Navy pilots for INS Vikramaditya operations. In future it will be used to develop and certify LCA Navy before the aircraft's induction into the Navy on board Indian Aircraft Carrier (IAC) INS Vikrant, which is currently under construction at Cochin.

DRDO was to demonstrate LCA Navy's deck operation capability at SBTF, Goa by mid 2014, but that is not likely to happen. Progress in developing LCA Navy - which first flew in on April 27, 2012 - was first stymied by problems with its redesigned and strengthened undercarriage. We can now expect more delay on account of a need to tweak the LCA's Flight Control Software (FCS) to facilitate deck operations.

The LCA-Navy FCS was reportedly developed with assistance from National Aerospace Laboratory (NAL) and validated by the US Navy. However, Aeronautical Development Establishment (ADE), Bengalure, has recently sought assistance to incorporate new features in OFP (Operation Flight Program) Software for LEVCON Air Data Computer (LADC), along with updates in the existing algorithms based on flight test results.

LCA Navy uses Levcons, active aerodynamic surfaces on the wing root leading edges, to control boundary layer flow and increase lift during low speeds. (LCA Tejas does not feature Levcons.)

LADC is part of Digital Fly by Wire FCS. The Quadruplex LADC would provide control logic and commands for the LEVCON actuation system, compute the control laws and mode logics for ski-jump, Auto throttle modes, Arrest hook systems etc. The computer also derives the necessary air data parameter required for the Flight Control System.

(After being augmented, LADC software would need more tweaks based on actual data generated in test flight.)

LCA Navy will feature hands-off take-off using ski-jump to ensure smooth transition to stable flight, and hands-off landing using steady AOA, autothrottle approach, flareless touchdown, and arrester hook engagement. During take-off and landing the pilot will be required to only give steering inputs to stay on the center line.

Thum! Kaun Aata Hai?: LCA Navy Will Long Remain Work in Progress

Will NLCA go through the same procedures like IOC,FOC like LCA?? @kurup

It will have to , every fighter does.

Ok what is the target year for IOC1???

These seem like a lot of pretty advanced features - Do other carrier fighters like FA-18E/F, Mig29K have these capabilities?

What systems are you talking about? FBW? FADEC? Arrestor hooks? Yes all naval fighters will have this these days....


I'm not sure about the auto/hands-free take off though, this sounds pretty unique and advanced (for ski-jump fighter a/c), I know the MIG-29K and SU-33 doesn't feature this and there are very few other advanced STOBAR configured fighters out there. As far as CATOBAR fighters go this is pretty common (as the catapult does most of the work and you will see when a Hornet or Rafale is launched off their ACCs the pilots have their hands on the sides of the cockpit-not on the controls).

Will India Export the Tejas ?

Nobody will buy.
But there is a possibility for Tejasmk2

@proud_indian Where does it talk about the time??

Yes, I meant the various"auto" features.

And I don't think even the CATOBAR jets have hands-off landing capability. IN seems to be going the IAF way - looking for Gen 5+ features in a Gen 4 light fighter. They should get a first version out in operation, and then upgrade incrementally.

Came across this video on Tejas on youtube most probably in Mandarin.Chinese members could u please throw some light as to what is being discussed??
