The argument for a HYPERSONIC missile testing ban
China and the United States recently conducted development tests of hypersonic missiles, designed to travel many times the speed of sound and reach targets thousands of miles away in an hour or less. Both tests failed, showing that hypersonic propulsion and flight—which involve extreme airspeeds, temperatures, pressures, and stresses, along with compact airframes and low weight—remain unproven technologies, even after decades of development. Solutions to the technological challenges of hypersonic flight may soon be within reach, using…
Tests underway for Hypersonic Technology Demonstrator Vehicle
A series of tests are underway for India’s first Hypersonic Technology Demonstrator Vehicle (HSTDV) and this will get a boost with the wind tunnel facility coming up here. Defence Research and Development Organisation (DRDO) is confident that HSTDV, which has already achieved 6.5 Mach, will achieve its aim of scramjet flight for 20 seconds. Mach is commonly used to represent the speed of an object when it is travelling close to or above the speed of sound. V.G. Sekaran, director general (missiles and strategic systems), DRDO, told repo…
