DRDO’s DRDL has completed a long-duration test of an actively cooled full-scale scramjet combustor at Hyderabad, running for over 1,200 seconds. The result validates indigenous air-breathing propulsion, including an endothermic liquid hydrocarbon fuel and high-temperature thermal coatings capable of handling extreme heat loads—an essential step toward deployable hypersonic cruise missiles.
DRDO has reportedly achieved a major hypersonic technology breakthrough after completing a long-duration test of an actively cooled, full-scale scramjet combustor in Hyderabad. The trial ran for over 1200 seconds and used indigenous fuel and cooling technology, marking a significant step toward India’s hypersonic missile development programme.
