HSTDV Cruise Vehicle.
DRDO can develop a hypersonic missile with scramjet engine in next five years, which will have the capacity to travel at more than two kilometres per second.
The HSTDV performed on all parametres, including combustion chamber pressure, air intake and control guidance.
At 11.03 am, the Agni missile booster took the hypersonic vehicle to height of 30 km after which the latter separated. Thereafter, the vehicle’s air intake opened and that led to successfully firing of the test scramjet engine. The combustion lasted for more than 20 seconds with the vehicle achieving a speed of Mach 6. The vehicle performed successfully on all the pre-determined parametres including the ability to handle combustion temperatures of over 2500 degrees Celsius as well as air speed.
HSTDV is an unmanned scramjet demonstration aircraft for hypersonic speed flight. Besides its utility for long-range cruise missiles of the future, the technology has multiple civilian applications also. It can be used for launching satellites at low cost.
Only US, Russia and China had tested similar kind of technology.
