Well, that's why a national effort for the indigenous Turbo fan engine is a must. Good thing our GTRE guys are confident that, they have solved the puzzle to build the turbo fan engine, and they are still waiting for the Supersonic test bed MIG-29 of IAF. Atleast for the organisation like GTRE, national test beds like Subsonic and supersonic test bed and a dedicated airport is needed to test the turbofan, and various LRU's.
1. MK-2 is nothing but the Naval version of LCA Tejas MK-1.
2. Higher thrust from F414 is needed for the carrier operation, because LCA won't be able to airborne with substantial load from the ski jump deck of the carrier.
3. Lca Tejas, whether MK-1 or MK-2 air intake was designed around the Kaveri Specs aka hiegher airintake pressure but it was never redesigned rather patched by the ADA by opening few intake ports to reduce the pressure, and in case of MK-2 increasing the Airinlet opening few cm. When we are talking about the airintake nozzle, that includes the whole nozzle including the Y duct, and not the external opening what you see in the picture.
4. Kaveri was delinked from the LCA project only but the development continues. Kaveri is only the proof of technology, the real engine will now be build on the technology build or developed with the Kaveri, and should be ready (reliable enough) for the mass production around 2024-25.
5. Problem with the Naval LCA is that being a single engine, the LCA didn't have the keel below, which strengthen the stucture, and needed to strengthen to take the load, pressure of the controlled crash landing during the carrier operation.
6. M88 (Snerma) and Dassault makes sense because, India have a secret project called AURA, the must needed part of the 5th Generation Air Warfare, and French have there own Nueron. No OEM responded for the RFI issued by the ADA for the development of the stealth USAV project, and it could be worked out with the french, in the deal of the Rafale.
I am totally fine with US engines..
My only concern was our indigenous fighter shouldn't be at the risk of sanctions .
Purpose of indigenous fighter would be lost, if it gets grounded because of sanctions.
