India joins the big league, Atmanirbhar Bharat soars

New Delhi: India has successfully flight tested hypersonic technology that will pave the way towards development of missiles travelling at six times the speed of sound.

With this successful demonstration, the country enters an elite club to become a member of the hypersonic regime. This is a step towards manufacture of advanced Hypersonic Vehicles. India became the fourth country after the United States, Russia and China to get this technology.

The Defence Research and Development Organisation successfully demonstrated the Hypersonic air-breathing scramjet technology with the flight test of Hypersonic Technology Demonstration Vehicle (HSTDV) at 11:03 am on Monday from the APJ Abdul Kalam Launch Complex at Wheeler Island, off the coast of Odisha. Defence Minister Rajnath Singh has appreciated the DRDO for achieving this milestone.

"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 were separated at hypersonic Mach number," said the DRDO in a statement.

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. Critical functions such as fuel injection and auto ignition of scramjet have demonstrated technological maturity.

The scramjet engine performed in a textbook manner. The parameters of launch and cruise vehicle, including scramjet engine, were monitored by multiple tracking radars, electro-optical systems and Telemetry Stations.

A ship was also deployed in the Bay of Bengal to monitor the performance during the cruise phase of hypersonic vehicle. All the performance parameters have indicated a resounding success of the mission. 

What it means?

♦    HSTDV can cruise at a speed of Mach 6 (six times the speed of sound) and an altitude of 32.5 kilometres in 20 seconds

♦    India joins an elite group US, Russia and China possessing the technology.

♦    HSTDV operates on a scramjet engine, as against the ramjet engine which is used on most missiles.

♦    Hypersonic cruise vehicle was launched using a proven rocket motor

♦    HSDTV has a range of uses, including missiles of the future, and energy-efficient, low cost and reusable satellite-launch vehicles
