ADA Tejas (LCA) News and Discussions

[vijay jagannathan]

The LSP-4 flight video [posted on the ADA website is good quality I must say. some very good close up shots. the Delta wings of Tejas are frighteningly thin and fragile and seem to be fluttering in the wind (though it may be my imagination). Wow!!! I mean how do these contibute to the aerodynamics? would it be able to withstand the terrific G forces without being ripped off??

Those wings are made of carbon composite material suffice to say how it will withstand repeated 9g pull and 3g push.

India will need help from the US to Develop the IAC-2. If, it wants it to be equipped with Catapults and much of the associated hardware.....In short expect to see much more of US assistance with the IAC-2 Design in the near future.

Otherwise, the IAC-2 will be decades off. (unless it keeps the Ski Jump)

Why is it that you make it look like that India has to be dependent on the US for everything it plans to do ?? Nobody expected us to build an AC and a nuke sub of our own, but we did that, and proved the critics wrong !! So did China ! Did you forget that the French also operate the CATOBAR equipped Charles De Gaulle and they can also help us with CATOBAR technology for our AC, especially since they already have been one of our prime suppliers of defence hardware for the past 2 decades also that the British are contemplating having CATOBAR capability, they can share the same knowledge with us ??

Actually, if Rafale is selected, the French would help us in IAC-2 CATOBAR design, in much the same way Russian goskov influenced IAC-1 design, same goes for Britain and we may buy f-35 in the latter case. No American help would be desperately required, but if they offer to supply Catapult with the installation consultancy, we may not say know, since in any case they would need to supply the crucial parts to construct the catapult, even if Britain of France helped.

India building its own catapults is a long way off, We would prefer jumping to EMALS, cos catapults are at the end of their growth cycle anyway and the only country that manufactures it is going to shut it down soon, after 2015.

 

[icecoolben]

Only US manufactures catapults, but consultancy to fix them can be obtained elsewhere

IN THE WIKIPEDIA REFERENCE SECTION OF THE hal tEJAS THERE IS A TECHNICAL PAPER ON THE AoA testing of tejas. its a PDF. can some one retrieve it cause I cannot.

Flight Of LCA Tejas LSP-4 Fighter Jet

 

[prateikf]

we alway's keep haering about trial's, flights and orders. But when on earth would would the LCA be inducted into the IAF in large number's and finally become a frontline fighter as it was supposed to have become atleast a decade ago?

 

[Rahul Singh]

Wait for six more month and you will see first 8 LCA in IAF colors.

BTW are you saying that ADA should cut short test cycle and fast track induction with a huge compromise on safety? Or are you saying that ADA should fast track test flight if not cut shot and risk loosing test aircraft?

ADA and LCA fans are well aware that ADA doesn't enjoys luxury of loosing prototype like SAAB in Gripen program and know that even a small accident can lead to salvation of whole project because of obvious nature of Indian media and critics.

Mate, i think link is dead or content is offline, i also failed many times. I guess, i have downloaded that file and have written in one CD let me find( even Google search fails finding my stuffs in my room sometimes). I'll try and upload ASAP.

 

[vijay jagannathan]

cheers rahul bhai. by the way i am based in qatar. met a mirage 2000 trainee pilot from Qatar air force. he promised to sneak me in. keeping my fingers crossed.

 

[vijay jagannathan]

wanna make some general obs: Tejas looks good in some angles. too many rivets on the body. is this for testing phase only? appears to take its time for take off. is it mandatory to deploy the chute for every landing or is it being done cause its testing phase?
P.S asks suneet is this ur first time mate and suneet says no Sir I did the PV1 flight. :emot15: Boy this ADA team is something. Tells a whole lot about familairity across the drawing board.

 

[Rahul Singh]

If you are talking about silver colored rivets on wings then yes they are for testing period only, precisely ground testing during vibration tests. BTW any uncertified jet have some rivets, attachments and extra load which are attracted to make aircraft fit to fly into unknown. When design comes to point where they know everything about their baby, they start ripping off all nappies and etc.

Brake chute is not mandatory but applied to stop jet in shortest possible distance say > 600 m. Every Russian origin jets carry them. BTW LCA can stop on mile long runway using wheel brakes and airframe drag like most of the western fighters.

P.S asks suneet is this ur first time mate and suneet says no Sir I did the PV1 flight. :emot15: Boy this ADA team is something. Tells a whole lot about familairity across the drawing board.

Where did you got this? ............I know that was not Suneet Krishna's first flight in LCA. Not sure which one but he has featured in one DD documentary on LCA. BTW chairman's duty is such that he may not be able remember things like this. One thing that can't be forgotten that Suneet returned after very long time and may have flown very less number of sorties. Also keeping track of who had and who will is ASTE 's responsibility while ADA's responsibility is only to ask for one pilot when they are ready for next test flight.

Buddy, any new invention is tested 1000s of times before coming into general use. You see LCA is a new jet taking 1000s of test flight but during MRCA, the jets already tested and manufactured earlier are tested again by IAF many times to assure that it does not compromise with the safety of its personnels, it works smoothly with our requirements and also they had to see that the money with which the GOI is supporting this project doesnt go waste in purchasing any kind of crap.

What is difference between NLCA & LCA?

Sorry, India is playing catch up and it can't do everything at once. The truth is India has "no" experience in developing Catapults nor Arresting Gear. So, to do so on her own it would take decades and Hundreds if not Billions of Dollars to do so! As for France and the Charles de Gaulle. It's Catapults are American Made and Designed! (plus many other systems)

In short if India has any hope of fielding a Conventional Aircraft Carrier (IAC-2) with Catapults anytime in the next 15 years. It will need the help of the US. Sorry, if you don't like it......it's just the reality of the situation.

BTW India has and is receiving a great deal of help from Russia to develop its Nuclear Submarine Technology.

Really, much of the reason for the MMRCA Contest. Is to gain exposure to more Advance Military Technology. In order to help India to develop it's own Defense Industry.

Clearly, India is making good progress. Yet, it takes time.............

Tejas Pv-1 waits for Kaveri Integration

In a busy Hangar in Hal complex a lone Tejas Pv-1 in the corner of the Hanger waits for Integration with the Kaveri engine , mating should have taken place a decade ago but delays in kaveri engine by GTRE only delayed the whole event , this also shows how off track whole Kaveri engine Project really is .

PV-1 has been pulled out of the current rigorous Tejas Test program since it no longer has all the new avionics equipments and its subsystems , nor does it has weapons integrated to carry out weapons testing ,but it will not join the fate of TD-1 and TD-2 where both have been dismantled and usable parts already been removed from the aircraft and waits it last resting place neither in a museum or a IAF Base .

Efforts are on to integrate Kaveri engine to its airframe , PV-1 is the only aircraft which was designed keeping Kaveri engine in mind , but it flew with American Ge engine , it still needs a lot of rework on its fuel lines and also on plumping systems ,so does LRU in the aircraft, Tejas LSP aircrafts have gone lot of changes recently to match LSP , PV-1 will also require number of changes to its mission computer and software .

Sources close to www.lca-tejas.org have told us that PV-1 up gradation and rework may delay the whole integration of Kaveri engine , HAL engineers are also working on possibility of integrating it with Tejas LSP-1 which is a newer airframe and has better equipment on-board then Pv-1 .

Which aircraft will take the honor will be decided soon and Kaveri engine will fly on board a Tejas Air frame by early 2011 or some time later in the year

Let's wait for Kaveri till it becomes operational, I do not understand why we give dates we cannot meet, instead give a date that will be not missed.

 

[luckyy]

isn't tejas with a under powered kaveri engine is good enough to be used as a AJT , comparable to Hawks we are buying...
