The era of hypersonic technology

  On 7th September 2020, India's Defence Research and Development Organization (DRDO) demonstrated hypersonic air-breathing scramjet technology with the test of Hypersonic Technology Demonstration Vehicle from  Dr. APJ Abdul Kalam Launch Complex at Wheeler Island in Bay of Bengal.  The Press Information Bureau (PIB) of India in a press release said, " The hypersonic cruise vehicle was launched using a proven solid rocket motor, which took it to an altitude of 30 kilometres (km), where the aerodynamic heat shields were separated at hypersonic Mach number. 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 i.e., nearly 02 km/second for more than 20 seconds. The critical events like fuel injection and auto ignition of scramjet demonstrated technological maturity. The scramjet engine performed in a tex
