Re: Tejas Mk.1 & Mk.1A News & Discussions: 09 February 2018

There are very good reasons to keep some of them metallic. It is not because of a technical challenge. Ofcourse, I understand, like areas around the engine, where heat is an issue. Having said that, hunger to find a way of doing it better is what drives innovation. Like the composite created by NAL...

Re: Indian Missiles News & Discussions - May 2017

Looks are deceptive. Astra, NGARM and QRSAM are very different missiles. NGARM has a dual pulse motor which Astra Mk2 is likely to inherit. But currently Astra Mk1 has a single pulse motor. QRSAM is completely different. It is heavier than the above two and shares next to nothing with them. It requi...

LCA already has a huuge draggy wing. Rather than adding canard, perhaps it would be better to adopt AMCA wing design or layout. (without internal bay off course) Are huge wings draggy??? You are either trolling, or have zero knowledge of basic aerodynamics. In either case, you should not have poste...

Tejas is a on a good path now. If Mk2 is not ready by the time Mk1A production completes, the kind of incremental changes that you guys are suggesting can be incorporated as Mk1B.
