India tested a hypersonic rocket engine, allowing to reduce the cost of space flight 10 times. The tests took place at the cosmodrome in the research center of Satish Dhawan, located on the island of Sriharikota on the East of the country. New propulsion system worked for about five seconds, confirming the expected performance.
Hypersonic ramjet engine (SCRAMJET) will dramatically reduce the weight of the propulsion system and the entire rocket and make rocket flights cheaper. Currently, the conclusion in the space of one kilogram of payload costs about $20 thousand, the new engine will reduce the price by almost 10 times.
