DRDO successfully flight tested Hypersonic Technology Demonstration Vehicle

Hyderabad: Defence Research & Development Organisation (DRDO) has successfully demonstrated the Hypersonic air-breathing scramjet technology with the flight test of Hypersonic Technology Demonstration Vehicle (HSTDV) from Dr. APJ Abdul Kalam Launch Complex at Wheeler Island, off the Odisha Coast, on Monday.

On this successful demonstration, the country enters into the Hypersonic regime paving way for advanced Hypersonic Vehicles.

The Hypersonic cruise vehicle was launched at 1103 hours, using a proven solid rocket motor, which took it to an altitude of 30 km, where the aerodynamic heat shields were separated at hypersonic Mach number, an official release said.

The cruise vehicle separated from the launch vehicle and the air intake opened as planned.
The hypersonic combustion sustained and the cruise vehicle continued on its desired flight path at a velocity of six times the speed of sound nearly 2 km/s for more than 20s.

The critical events like fuel injection and auto ignition of scramjet demonstrated technological maturity.
The scramjet engine performed in a text book manner and the parameters of launch and cruise vehicle, including the scramjet engine was monitored by multiple tracking radars, electro-optical systems and Telemetry Stations.
The scramjet engine worked at high dynamic pressure and at very high temperature.

A Ship was also deployed in the Bay of Bengal to monitor the performance during the cruise phase of hypersonic vehicles.

All the performance parameters have indicated a resounding success of the mission, the release said.
With this successful demonstration, many critical technologies such as aerodynamic configuration for Hypersonic manoeuvers, use of scramjet propulsion for ignition and sustained combustion at hypersonic flow, thermo-structural characterisation of high temperature materials and separation mechanism at hypersonic velocities.
In a statement, Union Defence Minister Rajnath Singh, congratulated DRDO scientists for achieving this milestone.

Department of Defence (R&D) Secretary and DRDO Chairman, Dr G. Satheesh Reddy also congratulated all the scientists and support staff for their contributions in proving highly complex air-breathing hypersonic technology.
