The 2022 goal is nice.

I wish we set similar deadlines for the TSTO and reusable rockets.

Re: UAVs, Drones, Remote Surveillance Tech

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.

Re: Indian Space Programme Discussion - Sept 2016

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. Not very difficult to get or even generate. SRBs are here to stay. And yes they will become all composi...

Re: Indian Space Programme Discussion - Sept 2016

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...

Re: Indian Space Programme Discussion - Sept 2016

I know that the TSTO was desgined with clustered SCE200 in mind. But, I am really waiting for the day when our SSLV is a reusable TSTO. Lower stage is L40 packaged as RLV. And upper stage is recoverable CUS12 stage. What a beautiful day that would be. https://lh3.googleusercontent.com/-Mtt8bwz_YNg/W...

Rafale is a wonderful aircraft. Very refined over generations starting with the originally Mirage, that’s four generations at least. Having said that some of the capabilities being touted here, on news channels, by sources and now an AM (no less) are physics bending.
