ADA Tejas Mark-II/Medium Weight Fighter

[AMCA MK1]

The idrw article talks of the afterburner adding 29kN thrust. Is 50kN dry thrust + 29kN wet thrust enough? That is about 5% less thrust than F404.

I don't know what being 'entrusted' with afterburner development means. Is going to start from scratch because the GTRE design was a failure or is going to add the finishing touches to the design handed to it?

you're f404 produces less thrust in indian conditions. Infact the 84.5kn wet thrust is not rated number while kaveri's published numbers are.

To be a viable engine, acceptable weight, thrust and durability levels need to be achieved. When is that likely to happen?

God's plan

I don't know much about jet designing but it seems to me that certain parameters like air mass flow, weight,dry thrust and SFC are nearly similar in case of 'Hypothetical' Kaveri and GE 414.

So is it possible to tweak inlet designs or make them 'MODULAR' so that LCA af mk2 can accomodate both eninges??

Can EJ200 replace F404 in MK1 A?

Can EJ200 replace F404 in MK1 A?

What would be the point? F404 works; EJ200 works .Both come with political strings. All foreign engines have political strings. EJ200 would invoke a multi-year delay in IAF getting a good light fighter just when it was finally about to get one 30 years late. Does anyone seriously want LCA to be 35-40 years late instead of just 30 years late?

It was in initial contest & ahead on technical greetings but F404 was L1

I know that the EJ200 was one of the engines along with the F414 for MK2, but eventually, the F414 was chosen because it was cheaper. What I am saying is can we use EJ200 as a backup plan for the F404/F414 delay?
We all know the EJ200 is a better engine, so even if it costs a bit more, it's always best to have a backup engine.

Kaveri is made of nickel-steel alloys right while the others are missing of Al-Li and/or titanium. Ofcourse it's heavy.

We're not behind in engine tech. We're behind in material tech

We're behind in engine tech , material tech & mfg tech . The west will be featuring Adaptive / Variable Cycle Engines soon . The Kaveri was supposed to be a VCE. We don't hear much on that front now though it'd be flat rated.

Get the idea of a backup but it does not make sense to me. It would have made sense if F404 had been under development and might not have come good or might have been cancelled. That's not the case - it's a late supply problem.

I saw it reported 19th December on indiandefenceupdates that HAL has informed the Standing Committee on Defence that a licence deal for F414 will be signed in 3-4 months. Who is holding things up? Early in 2024 GE's CEO thought it would be signed before 2025.

They want to massage Trump's ego & hopefully turn it into a photo op - something Trump can gloat about. Alternatively there could be last minute glitches to be sorted out. Or it could well be a combination of both.
