The Defence Research and Development Organisation (DRDO) on September 7 successfully flight tested a Hypersonic Technology Demonstrator Vehicle (HSTDV).
It is an unmanned scramjet vehicle with the ability to travel at six times the speed of sound.
Test Site - Dr A P J Abdul Kalam Launch Complex at Wheeler Island, off the coast of Odisha.
The HSTDV tests the indigenously developed hypersonic air-breathing scramjet technology.
The scramjets are a variant of air breathing jet engines and have the ability to handle airflows of speeds much higher than the speed of sound.
Hypersonic speeds are five times (or more) higher than the speed of sound.
