Topic: DRDO test fires Hypersonic Technology Demonstrator Vehicle
Topic in Syllabus: Security Issues
India on 12 June conducted a successful first test flight of the indigenously developed Hypersonic Technology Demonstrator Vehicle (HSTDV) from a base off the Odisha coast.
It has a range of uses, including missiles of the future, and energy-efficient, low cost and reusable satellite-launch vehicle.
What is HSTDV?
- Hypersonic Technology Demonstrator Vehicle in short it is known as HSTDV. It is an unmanned scramjet demonstration aircraft.
- It is designed to cruise at Mach 6 speed with scramjet engine up to an altitude of 32.5 kilometres in 20 seconds.
• HSTDV is dual-use technology thus with a scramjet engine, HSTDV can cruise at Mach 6 speed and can have multiple civilian applications.
• It can be used for launching satellites at low cost and can also be available for long-range cruise missiles of future.
• The design for airframe attachment with the engine was completed in the year 2004.
About Scram-Jet technology
In scram-jet technology, fuel combustion takes place in a chamber in missile at supersonic speeds while in a ram jet system, the system collects air it needs from atmosphere during flight at subsonic speeds and propellants burn in combustion chamber.
The only other countries that possess this technology are the US, Russia and China.
Hypersonic Technology Demonstrator Vehicle is
- an unmanned scramjet demonstration aircraft
- allows supersonic combustion
- can cruise up to six times the speed of the sound
