The Defence Research and Development Organisation (DRDO) has recently conducted the maiden test of an indigenously developed Hypersonic Technology Demonstrator Vehicle (HSTDV) .
About the test
In the test, a missile with the technology demonstrator vehicle mounted on it is launched and the vehicle is released only after the missile reaches a certain altitude and velocity.
Objective of HSTDV project
Through the HSTDV project the idea is to demonstrate the performance of a scram-jet engine at an altitude of 15 km to 20 km.
Under this project, DRDO is developing a hypersonic vehicle that will be powered by a scram-jet engine. This is dual-use technology, which when developed, will have multiple civilian applications. It can be used for launching satellites at low cost. It will also be available for long-range cruise missiles of the future.
In scram-jet technology, combustion of fuel takes place in a chamber in the missile at supersonic speeds. This is different from a ram jet system where the system collects the air it needs from the atmosphere during the flight at subsonic speeds and the propellants burn in the combustion chamber.
