Context:

DRDO test fires Hypersonic Technology Demonstrator Vehicle

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.

 

Uses:

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.

 

Significance:

The only other countries that possess this technology are the US, Russia and China.

 

Sample Question:

Hypersonic Technology Demonstrator Vehicle is

  1. an unmanned scramjet demonstration aircraft
  2. allows supersonic combustion
  3. can cruise up to six times the speed of the sound
