Advanced Technology Vehicle (ATV), a sounding rocket (research rocket) with a solid booster carrying advanced scramjet engines, was successfully flight-tested.
This first experimental mission of Indian Space Research Organisation is aimed at the realisation of an Air Breathing Propulsion System which uses hydrogen as fuel and oxygen from the atmosphere air as the oxidiser.
With this, the ISRO had successfully demonstrated its capabilities in critical technologies like ignition of air breathing engines at supersonic speed, air intake mechanism and fuel injection systems.
Technological challenges handled by ISRO scientists during the development of the scramjet engine include the design and development of hypersonic engine air intake, the supersonic combustor, proper thermal management and ground testing of the engines.
With this, India became the fourth country to demonstrate the flight testing of a scramjet engines. This mission is a milestone for ISRO’s future space transportation system.
