The Advanced Technology Vehicle (ATV), a sounding rocket (research rocket) with a solid booster carrying advanced scramjet engines, was successfully flight-tested from the launch pad of the Sathish Dhawan Space Centre, also known as Sriharikota Range (SHAR), at Sriharikota on Sunday.
Things to know about the Scramjet Engine
- India is the fourth country to demonstrate the testing of Scramjet engine
- The scramjet engine is used only during the atmospheric phase of the rocket’s flight.
- Scramjet engines will help bringing down launch cost by reducing the amount of oxidiser to be carried along with the fuel.
- Scramjet engines designed by ISRO uses hydrogen as fuel and the oxygen from the atmospheric air as the oxidiser.
- The test-flight is maiden short duration experimental test of ISRO’s scramjet engine with a hypersonic flight at Mach 6 (six times the speed of sound).
- Two scramjet engines were “hugging” the rocket on its sides and when the rocket reaches a height of 11 km the scramjet engines would start breathing air.
- The ATV rocket weighed 3,277 kg during lift-off.
