Hypersonic respiratory jet technology was successfully tested by DRDO

Hypersonic respiratory jet technology was successfully demonstrated by the Defense Research and Development Organization (DRDO) on Monday with a Flight Test of the Hypersonic Technology Demonstration Vehicle (HSTDV), which will lead in the future to the development of hypersonic missiles and cruise vehicles.

“This is a great technological advance in the country. These tests pave the way for the development of more critical hypersonic technologies, materials and vehicles. This places India in a select club of nations that have demonstrated this technology, ”

said DRDO President G. Satheesh Reddy.
  • A test of the technology demonstrator was carried out in June 2019. “With this success, all critical technologies are now set to move on to the next phase,” Defense Minister Rajnath Singh said on Twitter.
  • The HSTDV took off at 11:03 a.m. Monday from the Dr. APJ Abdul Kalam launch complex on Wheeler Island off the coast of Odisha.

“The hypersonic cruise vehicle was launched using a proven solid rocket motor, which took it to an altitude of 30 km, where the aerodynamic heat shields separated at hypersonic speed,”

the DRDO said in a press release.
  • The hypersonic technology demonstration vehicle takes off[ the cruise vehicle separated from the launcher and the air intake opened as expected.

“Hypersonic combustion was maintained and the cruise vehicle continued on its desired flight path at six times the speed of sound, or nearly 2 km / s for more than 20 seconds,”

DRDO Said

“Important breakthrough”

  • With the technology, cruise missiles could now travel at hypersonic speeds.
  • The Scramjet engine is a breakthrough. Air enters the engine at supersonic speed and exits at hypersonic speeds.
  • The vehicle reaches a certain altitude, then cruises and also reaches very high temperatures, up to 1000-2000 degrees Celsius, upon re-entry.
  • After the anti satellite test, this is the biggest achievement recently.
  • Critical events such as the fuel injection and self-ignition of the scramjet demonstrated technological maturity.
  • The scramjet engine worked classically. It operated at high dynamic pressure and very high temperature.
  • DRDO, with this mission, has demonstrated capabilities for a very complex technology that will serve as a cornerstone for next-generation hypersonic vehicles in partnership with the industry.

Monitoring

  • The parameters of the launch and cruise vehicles, including the jet engine, were monitored by various tracking radars, electro-optical systems, and telemetry stations.
  • A vessel has also been dispatched to the Bay of Bengal to monitor the performance during the cruise phase of the hypersonic vehicle.
  • With this successful demonstration, many critical technologies such as the aerodynamic configuration of hypersonic maneuvers, the use of scramjet propulsion for ignition and sustained combustion with hypersonic flow, the thermostructural characterization of high temperature materials and the separation mechanism, at hypersonic speeds they have been validated, the DRDO told.
