Re: Advanced Medium Combat Aircraft: News & Discussion - 30 August 2019

Re: Advanced Medium Combat Aircraft: News & Discussion - 30 August 2019

The nomenclature by itself has little meaning and its definition keeps changing. The proposed LCA Mk2 with a single F414 is being called a Medium Weight Fighter now. And looking at its projected Payload and Internal fuel values that seems correct since the M2k is also considered a Medium category a...

Re: Advanced Medium Combat Aircraft: News & Discussion - 30 August 2019

No single requirement parameter can be looked at in isolation. A larger engine would push the size towards a heavy fighter. That is obviously not an option unless the IAF commits to a significant change in direction. It would certainly be easier to design a high supercruiser with some of the larger ...

Re: Advanced Medium Combat Aircraft: News & Discussion - 30 August 2019

It also depends on whether the projected empty weight and MTOW specs can be met. The KF-X has relatively ambitious specs of only ~12 tonnes empty and 25 tonnes MTOW with 2 F-414's. That is not a bad T:W ratio if they can achieve it. In fact it would be much better than that of the F-35A. Of course ...

Should be 80K feet. I believe F22 are capable of operating at 100K ft, so a AMCA capable of 80K ft would be a good achievement.

Where did the 120Kn number come from? The article from TOI linked on the previous page refers to an indegenous 110 kN class engine. That is totally doable within the design constraints of the F-414 so that design changes on the MWF and the AMCA are minimal.
