DRDO Conducts Active Cooled Scramjet Subscale Combustor Ground Testing For Over 1,000 Seconds News24 –

The Defence Research Development Organisation (DRDO) has achieved a significant milestone in the field of Hypersonic Weapon Technology. The DRDO said in a statement that Hyderabad’s Defence Research Development Laboratory (DRDL) has conducted long duration Active Cooled Scramjet Subscale Combustor ground testing for more than 1000 seconds duration at the newly built state of art Scramjet Connect Test Facility (SCPT) on April 25. 

The ground test conducted is in continuation of an earlier test reported for 120 seconds in January 2025. With today’s successful test, the system will be soon ready for full scale flight worthy combustor testing.

The DRDO further added, “Hypersonic Cruise Missile (HCM) is class of weapons that can travel more than five times speed of sound (> 6100 Kmph) for long duration and is powered by Air breathing engine. Air breathing propulsion systems having supersonic combustion plays critical role for long duration cruise conditions. This test validates the design of long duration scramjet combustor as well as test facility. It is an outcome of an integrated effort put by the DRDO labs along with industry and academia and paves a strong base for nation’s Hypersonic Cruise Missile Development Programme.”
