Krate M this is you are talking about https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&uact=8&ved=0CCwQFjAC&url=http://www.drdo.gov.in/drdo/drdojsp/downloadtndr.jsp?tenderName=6881&McrId=LRDE*Electronics%20&%20Radar%20Development%20Establishment&p=lrde_AirborneLiquidCirculationSystem_Specs_20.pdf&ei=RkpsVLDNN6eOmwWk64KwBw&usg=AFQjCNHFGilHDiwdHDs87aQqGErSOUXFmQ&sig2=orEfNwMPFBXLacVFHMM_mQ&bvm=bv.80120444,d.dGY

@ni8mare
Yup, that's the one. So only liquid circulation system is needed. See the specs and architecture is finalized.
2650 watts and other items. People here forget about the DRDO AEWC project, and the experience of DRDO in AESA radar. With Israel help if needed, we are going to do it.

yeah saw that it dissipates 2650W heats>>>means AESA unit is ready or going through testing......according to tender it will at least 1 year before it could be ready.....

Yup, the testing is on and now preparation for installing it in fighter plane have been started. This fits the timeline for aesa in LCA.

Its Back to basics for GTRE after Kaveri Engine is scrapped | idrw.org

GTRE just confirmed three engine projects
1) 20 kn for uav

2} 40 kn for umanned bomber

3) at planning stage 115 kn for future requirement

LCA Tejas LSP4 at Jaisalmer last month for more weapons release tests

Remember the presentation by Dr. VK Saraswat some years ago...about AMCA having ~100kN engines?

Definitely the new 115kN developments will be used on the AMCA ultimately...with adequate supercruising capability.

The Kaveri maybe scrapped but the knowledge gained in that project will be very useful
for future project.

I wouldn't get my hopes up. Making a contemporary jet engine is one of the hardest projects a nation can undertake.
Especially since the goal post is always moving.

When did China work on jet engines, any idea ?

Thier timelines should be a realistic target for our domestic engine project.

Looks like under chase paint of cars

Do we have any tejas with black colour ?

The Kaveri itself demonstrated a lot of tech - you know it was designed as a Variable Cycle Engine (VCE),
a very advanced design for it's time.

It sure takes a lot of time to develop a working turbofan but the experience gained in Kaveri helps.

The 2-seater trainer version of the Tejas (PV-6) in flight.

@SpArK in my opinion Indian air force should induct them this will encourage the design team and plus there daily use will give better look inside..nice snaps

Older DRDO specs showed the requirement of a 110kN engine for AMCA, so aiming a bit higher now seems to be appropriate "for the fighter projcet", but completelly nonsense, by the fact that they simply FAILED with Kaveri and rather basic 4th gen capabilities and requirements. There is nothing to gain from Kaveri for a NG engine, when you not even were able to develop a current engine in a reliable version and fit it to any application (not necessarily the LCA, but Mig 29K for example). So that BS that they claim about know how not wasted is just to fool the public and distract from their failures. Infact, if there was anything to gain for a NG engine, why not further develop Kaveri in the first place, instead of starting from scratch again and if they don't use the search for a possible AMCA engine directly for a joint development, they haven't learned anything from their mistakes!

Which again shows what nutcase are leading DRDO! Instead of realizing the limits of indigenous developments today and aiming for a realistic engine developments, with basic level of techs and performance, they always aim too high, because they want to brag about being world class. Same goes for LCA, why does it need NG displays, why does it need stealth shapings or other things they state infront of the media? We would had gained far more if it would offer the aimed performance goals and could had been inducted years ago, in a simple but achievable approach of the development. We still fail at the basics, radar and engine developments, just as aircraft design and our aim must be to improve these fields in a steady approach, not just jumping to the next one with even higher aims.

When we can't design a single aircraft without design issues or much overweight, how can we realistically say, we will be able to do a stealth design that is far less aerodynamic?
When we wasn't able to develop a current gen radar or engin with basic performance capabilities, how can we realistically say, we will be able to do it with NG performance and capabilities?

The excuses are always the same, it was an "ambituous" program, it was our first attempt..., but that doesn't make the nation more capable or less reliant on foreign imports.

Well there may be some persons in Indian defense establishment who don't want TEJAS full operational.in my opinion each time air force rejects it and calls for new modification, design team is in problem not air force is.
