            HSTDV is a carrier vehicle built by DRDO for carrying the hypersonic & long-range cruise missile. Initiated in the decade of 2010, but it was cleared for testing in 2019 subsequently flight testing was conducted. On the 7th of September, 2020 the Scramjet engine was tested. HSTDV was mounted on a solid rocket motor and taken to a height of 30 km. After which it separated from the rocket and it's air intakes opened as per planned. HSTDV achieved a speed of 2km/sec (7200km/hr) approximately for over 20 sec. 

           Important Terms:-

                1. Hyper Sonic:- Typically, any vehicle traveling with the speed of 5-10 mach number is called Hyper Sonic vehicle. 5-10 mach number results in a speed of 6100-12400 km/h. 

                2. Scramjet Engine:- Supersonic Combustion ramjet engine. Typically, These engines compress air at supersonic speed & combustion takes place at the same speed. These engines are mounted on another delivery vehicle till it attains supersonic speed and required altitude.

            Concluding, India joined the elite club of the USA, Russia & China with hypersonic technology. China is the only country that has officially inducted hypersonic technology in its arsenal. Considering the elevated conditions at borders it is a morale booster for India. Other than military purposes this technology has civilian applications too like launching satellites at low cost. So, it's a dual-use technology. Many more tests are supposed to be done for making the technology perfect.

Note:- The availability of the confirmed information is not much, as it is a highly secretive mission. I have written this blog for getting little insights for the aspirants who will be facing written exams & interviews in the upcoming months. Where there is a possibility of a question on this test of HSTDV.
