Hypersonic cruise missiles belong to a class of weapons that can travel more than Mach 5, or five times the speed of sound (over 6,100 km/h). These are powered by an air-breathing engine.
The Defence Research and Development Organisation (DRDO) achieved a major milestone on Friday as it conducted scramjet combustor ground testing for more than 1,000 seconds. The Defence Research & Development Laboratory (DRDL), a Hyderabad-based laboratory of the DRDO, has developed a long-duration supersonic combustion ramjet or scramjet-powered hypersonic technology.
In a statement, the defence ministry said that the DRDL conducted the “long-duration active cooled scramjet subscale combustor ground testing for more than 1,000 seconds at the newly built state-of-the-art Scramjet Connect Test Facility at Hyderabad.”
The statement further stated that with the “successful test, the system will soon be ready for full-scale flightworthy combustor testing”.
The ground test is a continuation of the earlier test reported for 120 seconds in January. The successful ground test had marked a “crucial milestone in developing next-generation hypersonic missiles”, the ministry had said.
The latest test implies India’s significant stride in developing hypersonic cruise missiles, which belong to a class of weapons that can travel more than Mach 5, or five times the speed of sound (over 6,100 km/h), for a long duration and are powered by an air-breathing engine.
In its statement issued on Friday, the ministry stressed that the air-breathing propulsion systems, having supersonic combustion, play a critical role in long-duration cruise conditions.
“This test validates the design of the long-duration scramjet combustor as well as the test facility. It is an outcome of an integrated effort put in by the DRDO labs along with industry and academia and paves a strong base for the nation’s Hypersonic Cruise Missile Development Programme,” it added.
Defence Minister Rajnath Singh complimented the DRDO, industry partners and academia for the “remarkable achievement”
