Re: Indian Missiles News and Discussions - May 2017

They are preferred for being more smoke less. For ISRO/DRDO the focus is on having composite motor casings and parts. DRDO is also dabbling with NEPE based propellants.

Can anyone (Indranil perhaps with your sources?) confirm if the Tejas' ejection seat is reclined? If so, at what angle? Gripen seat recline is 28 degrees and F-16 is 30 degrees. Supposedly helps in increasing G load tolerance for the pilot. It's reclined. Have forgotten the amount. Can find out. Bu...

I don't know what is exactly happening but ADE has floated tenders to build nacelles and housing structures for Austro engines on Rustom 2. May be as back up plan in case the desi powerplant fails to deliver performance. If yes, then very prudent.

We are behind the curve on that. The TFTA SC engines use more clean burning fuel than kerosene. Leaves less soot on the engines. Where are you going to source such fuel from? They run on methane.

The original plan was 5 tons to GTO. Essentially, make the lower SC400 stage of HLV reusable. But, I will go back to my usual Rona dhona. Why not have a smaller version with a single SCE200 engine? Even if they achieve 1% mass fraction, with the C27 used as the upper stage, you will get a launcher w...
