India's Defence Research and Development Organisation (DRDO) in a first, has successfully test-fired an indigenously developed Hypersonic Technology Demonstrator Vehicle (HSTDV) on 13th June 2019.
The Hypersonic Technology Demonstrator Vehicle (HSTDV) test was conducted from launch pad number-4 of Integrated Test Range (ITR) at Abdul Kalam Island off Odisha Coast.
The Hypersonic Technology Demonstrator Vehicle (HSTDV) is an unmanned scramjet demonstration aircraft. It is designed to cruise at Mach 6 speed with scramjet engine.
The Hypersonic Technology Demonstrator Vehicle (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 the future.
In 2008, DRDO stated that through HSTDV project idea was to demonstrate the performance of a scram-jet engine at an altitude of 15 km to 20 km, is on. Thus under this project, DRDO developed a hypersonic vehicle that will be powered by a scramjet engine.
In scram-jet technology, fuel combustion takes place in a chamber in missile at supersonic speeds.
