Deep TOT on engine was a part of the sukhoi deal. Have we been able to use it to overcome our problems with Kaveri? Proof of the pudding lies in eating it sir. So far the pudding hasn’t turned out quiet as expected.
Is the Sukhoi Engine in the same Class as the Kaveri Engine? Is the Sukhoi-30 (AL-31FL) engine as technologically advanced as the Eurojet EJ200?
Let us have a look(as per wiki).
AL-31FL
Dry weight: 1570 kg
Maximum thrust: 122.58 kN with afterburner
Thrust to weight ratio: 7.14:1
EJ200
Dry weight: 989 kg
Maximum thrust: 89 kN with afterburner
Thrust to weight ratio: 9.175:1
Kaveri
Dry weight: 1,100 kg
Maximum thrust: 81.1 kN with afterburner
Thrust to weight ratio: 7.8:1
The Thrust to weight ratio proves that Kaveri's Thrust to Weight Ratio is better than AL-31FL. The Kaveri Engine has infact produced 83-85 KN in June 2010 with the Snecma Core. An engine with 85 KN thrust actually doesnot meet the current requirement. The current requirement is for a 90 + KN engine for Tejas MK-II.
Are you sure that what ever Kaveri has achieved in June, 2010 has been done by GTRE and that GTRE has not taken any input for achieving the same from the Deep TOT on Sukhoi Engine or from Snecma? How are you so sure?
Yes Sir, The proof of pudding is in eating but not in eating a half cooked pudding. The Kaveri is still in development. Ok, you can say, the pudding is taking too much time in getting cooked. I agree. This is the reason why I suggested in some of my earlier post that the Kaveri Project needs to accelerated with some measures like fast tracking and crashing the timelines.

They are merely reducing costs for themselves by sharing development cost and ensuring the production numbers. One can be rest assured, we will be confined to non-critical or non-cutting edge areas as far as stealth is concerned.
My argument was whatever the Russian are doing is for money and You seem to agree. I no where mentioned that the Russians are going transfer the full futuristic stealth technology to India for the FGFA.

There are no short cuts to success. With 21 years of exp. GTRE needs just a gentle push in the right area. Others are ready to give it now because they see the inevitable. They know we will be there in x number of years. They just want to make money by making it x - n number of years.
Yes, I fully agree with this and this is the point for my argument i.e. reduce the development time of an acceptable Kaveri Engine, by hook or by crook.
