India tests hypersonic technology demonstrator with scramjet engine for 20 seconds
"The advantage of the Indian Supersonic Combustion RAMJET (SCRAMJET) engine is the use of hydrocarbon fuel which is cheap compared to cryogenic fuel used by Israel and Russia. Our engine can be switched off, started and used just like a jet engine instead of a rocket engine type approach. This engine is more sophisticated than a jet engine.

Before a commercial flight, this technology will see a military use" added Dr Prahlada.
