I don’t expect to see this thing fly into space any time soon. They don’t seem to be serious about it, as indicated by this:
“The RLV-TD will act as a flying test bed to evaluate various technologies like hypersonic flight, autonomous landing, powered cruise flight and hypersonic flight using air breathing propulsion. First in the series of demonstration trials is the hypersonic flight experiment (HEX),” it said.
“Powered cruise flight”? Of what value is that to getting into space (other than giving you azimuth and longitude flexibility)? Unless you can refuel it in flight, it will kill your performance.
I’ll repeat the three rules of aerospace vehicle design:
1) If you want to cruise, use an airbreather.
2) If you want to turn, use a wing.
3) If you want to accelerate, use a rocket.
In order to get to orbit, you have to accelerate.
[Update a few minutes later]
You’ll know that the Indians are serious about building reusable orbital vehicles when they start working on reusable suborbital vehicles.
