Hmmm... Chinese J10 has Al31 which delivers 12500 Kgms thrust. F35 has an engine that delivers 181 KN thrust..
Going by the logic sought to be shown here India will never be allowed to design and manufacture engines on its own. That seems to be motto of the vendor agents here. This thread opens with close down GTRE first for that is the seed that gives the ability to grow..
If your arguments are correct that increased thrust is the minimum for an aircraft to win combat, why did we choose the Mirage 2000 which has far lower thrust than F16 and why the Mirage 2000 is considered to be equal to the F16. An aircraft only needs optimum engine power to get in to combat.. At the moment the current Kaveri engine is more than adequate for a fighter that will base its efficient killing power on BVR missiles. True in CAS and A2G roles thrust is extremely important but we are not building the Tejas in hundreds and plan to build few squadrons of basic variant.
If indeed the max thrust is what is needed the solution is simple. Take the 117S engine and use it on the LCA MK2 version, You have the engine ready now..
Alternatively make LCA Mk2 a twin engine cousin of Tejas and use Two Kaveri engines. As GTRE reports the thrust now is 81 KN and put two engines and you get more than what we need.
You can also use he current Kaveri engine even assuming the earlier figure of 65KN to re-engine the Jaguars, Some bit of modifications will be needed but remember Jaguar is a stable airframe and remains the backbone of our strike forces. Jaguar has a known problem with poor thrust and yet it remains our main strike fighter for more than 3 decades now. No complaints are made here about that and the applicability of Kaveri to a modified kind of Super Jaguar which can also extensively use the Tejas Avionics is not even dreamt. If this were to be china it would have already been flying in squadrons.
A combat capable AJT in the 20 tons category can also be built using Kaveri. It will be cheap but will have the range and fire power. We need not think about small AJTs alone to train. Fire Power, range, ability to deliver good amounts of bombs if needed in combat will all come in plenty and if we add proper radars it can also do BVR and WVR missiles and can easily supplement the regular combat aircraft apart from being a trainer.
Kaveri can also be used to build a UCAV based on the LCRA built years back. That was a good LOW Rcs design and can be modified to make a low observable UCAV.
We now have the engine and we need to improve it and it is a continuing process. What has been achieved and what is available can be used to a lot of uses if only IAF is able to think, dream and perform.
Unfortunately the only incidents in fighter design where IAF has contributed is the unsuccessful HF 24 project and the sucessful SU30MKI project but the later is only a significant modifications of the existing aircraft and not IAF contribution was basically in user requirement. With the exception of integration and possible project conception and management what is IAF role here is not clear.
Simply thinking that only western engines alone would deliver and Kaveri must be killed GTRE must be closed are the kind of things we hear in a forum supposed to promote Indian Defense.
I'm sure would receive that Tejas is too small an airframe and he 117S engine is too big etc but cannot we extend the size of the airframe.. It will only increase out capabilities.
Only in India we have people who want to write against nation building. Paki sites though not credible on tech and info certainly do not have this self destructive attitude..
