Kaveri Engine

[Spitfire IX]

We now have a material knowledge and capability to make a Kaveri engine that can compete with f404 on equal terms(except lifespan, Kaveri will 5000+ hours, while f404 will be 6000+hours).
The problem is, f404 are already "On order" for tejas deal has been signed years ago.
And Kaveri with afterburner still hasn't been on tejas for testing.
But its having this capability and confidence that caused GTRE to request the government to provide a tejas to test the improve engine.

DRDO and GTRE to Integrate Dry Kaveri Engine Derivative into LCA-Tejas Trainer Aircraft – Indian Defence Research Wing

Though so far don't know if they will get it.

Interesting.

The governments of India over 20+ years have failed to invest in a flying testbed. Is such a tool a requirement to developing an engine? Since the Russian, American, British and French OEM's test their engines on flying testbeds why did India not feel it necessary to get itself one? It would not be stuck where it is now, would it?

But we are where we are. Where India has been since it started: ill equipped to develop a jet engine.

If dry Kaveri were certified, that could be used in Tejas, couldn't it, for testing purposes? Can you flight test an uncertified wet Kaveri in a single engined-aircraft?

Can't we replace ge f 404, when their life cycle of ends in future ?, a fighter jet goes through multiple engines in life.

Not really. You can repare the engine by replacing some used parts. Not impossible that at the end all the components have been replaced at least one time....

I'm talking about replacing ge404 IN20 with wet Kaveri after 6000 or more so life cycle of ge404 engine ends.

IAF will never agree to replace an engine with AB with another without.
I add that some FBW problems may occur because of a deep center of gravity change.
