Re: Tejas Mk.1 & Mk.1A: News & Discussions: 23 February 2019

Quite ironic that most people who talk of RCS have not seen scaler/vector Network Analyzer in their life. I once was building my own anachoic chamber with special stuff absorbing surface, and calibrating it for required system accuracy, it gave deep quantitative insight to RF reflections in a near ...

Re: Tejas Mk.1 & Mk.1A: News & Discussions: 23 February 2019

Just to point out, now we can imagine, what it exactly meant when its said that the canard configuration had only marginal benefits over the double delta wing, which is a simpler and hence obvious choice. A pure delta with canard would end up in much smaller wing area, albeit at higher slope of C_L...

Karan, Why care? If there is an ASAT test, there would be debris. Actually, head on collision creates the lowest chances of debris to reach higher apogee orbits. But, hitting the satellite on the way down would create the most atmosphere intersecting debris (if I am not wrong). Most debris from the...
