Context

Recently, India conducted a successful first test flight of the indigenously developed Hypersonic Technology Demonstrator Vehicle (HSTDV). The only other countries that possess this technology are the USA, Russia and China.

About

More on news

  • The vehicle was test launched using the Agni 1 missile platform.
  • In the test, a missile with the technology demonstrator vehicle mounted on it is launched.
  • This test marked a landmark achievement in airborne ballistics and reusable rockets.
  • A successful test could boost the development of a hypersonic cruise missile, the Brahmos II, which is currently under development with Scramjet technology.

Features of HSTDV

  • India’s HSTDV was test-fired by the Defence Research and Development Organisation (DRDO) from the Integrated Test Range (ITR).
  • HSTDV is an unmanned scramjet demonstration vehicle that can cruise up to a speed of mach 6 (or six times the speed of sound) and rise up to an altitude of 32 km in 20 seconds
  • It has a range of uses, including missiles of the future, and energy-efficient, low cost and reusable satellite-launch vehicle.
  • The HSTDV cruise vehicle is mounted on a solid rocket motor, which will take it to a required altitude, and once it attains certain mach numbers for speed, the cruise vehicle will be ejected out of the launch vehicle.
  • The scramjet engine gets ignited automatically later. Besides its utility for long-range cruise missiles of the future, the dual-use technology will have multiple civilian applications too.
  • The key areas of technological emphasis in this project include hypersonic propulsion, wind transmission with minimal drag loss, enhancing aerodynamics, and refining the scramjet engine.
  • Various electro-optical tracking sensors, telemetry stations and radars tracked the vehicle through its course.

Significance

  • It can be used to launch satellites at low cost & will help add to India’s ballistic missile defence capabilities. This test puts India in an elite club of nations definitely
  • Security-wise, a hypersonic cruise missile can be key in taking out hostile airborne attacks, giving the Air Force an edge in terms of launching offenses of their own.
  • It is also a technological feat that can be incorporated into other areas such as sweeping surveillance tasks, all the while being energy efficient in operation.

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.
