The first experimental mission of a sub-scale Scramjet engine, towards the realization of an Air Breathing Propulsion System, was successfully conducted on August 28, 2016 (at 0600 hrs IST) from Satish Dhawan Space Centre, Sriharikota.

Various flight events, namely, burn out of booster rocket stage, ignition of second stage solid rocket, functioning of Scramjet engines, followed by burn out of the second stage took place exactly as planned. With this experimental flight, critical technologies such as ignition of air breathing engines at supersonic speed, holding the flame at supersonic speed, air intake mechanism and fuel injection systems have been successfully demonstrated.

The total cost incurred towards carrying out the first experimental mission of the Scramjet engine is Rupees 8 Crores.

The Scramjet engine used in the first experimental mission is a scaled-down version to demonstrate proof-of-concept.

Scramjet engine technology is a complex technology which is yet to be fully proven worldwide. A series of technology demonstration tests are required before inducting the engine with required thrust into future launch vehicles.

The technology will be useful only during the atmospheric phase of the flight of launch vehicle and will benefit in bringing down the cost of access to space, by reducing the need of carrying the oxidizer along with the fuel.

Reusable Launch Vehicle
(Source: Indian Department of Space; issued Dec 07, 2016)
ISRO has successfully carried out the first experimental mission of Reusable Launch Vehicle – Technology Demonstrator (RLV-TD), on May 23, 2016 from Satish Dhawan Space Centre, Sriharikota. In this mission, critical technologies such as autonomous navigation, guidance & control and reusable thermal protection system have been successfully demonstrated.

The Development of Reusable Launch Vehicle is a technical challenge and it involves the development of many cutting-edge technologies. Presently, it is in the preliminary stage of total developmental process. A series of technology demonstration missions would be required before it is made operational.
