India’s defense agency DRDO successfully tested a hypersonic scramjet combustor engine for over 1,200 seconds (around 20 minutes) in Hyderabad. This was a major improvement over an earlier 700-second test conducted in January 2026. �<br />Interesting Engineering +1<br />The test is important because scramjet engines are used for hypersonic cruise missiles that can travel faster than Mach 5 while remaining maneuverable, making them difficult for current air-defense systems to intercept. �<br />Interesting Engineering +1<br />The engine uses “active cooling” technology to survive the extreme heat generated at hypersonic speeds. DRDO scientists also developed:<br />A special flame-stabilization system to keep combustion stable at ultra-high speeds<br />Advanced ceramic thermal barrier coatings that can withstand temperatures beyond steel’s melting point<br />An indigenous liquid hydrocarbon fuel that improves cooling and ignition performance �<br />Interesting Engineering +1<br />Officials said the successful ground test strengthens India’s hypersonic cruise missile program and pushes the country further into advanced aerospace and next-generation military technology. �<br />The Times of India +1Here are some <br />India Successfully Tests Hypersonic Missile Engine for 20 Minutes<br />DRDO’s New Hypersonic Engine Breakthrough Explained<br />India Moves Closer to Mach 5 Hypersonic Missiles<br />India’s Hypersonic Scramjet Engine Passes Major Test<br />Inside India’s Advanced Hypersonic Missile Technology<br />DRDO Achieves Big Milestone in Hypersonic Weapons Program<br />India Tests Powerful Hypersonic Missile Engine at Extreme Speeds<br />New Indian Hypersonic Engine Could Change Modern Warfare<br />How India’s Scramjet Engine Survived Extreme Heat<br />India Enters New Era of Hypersonic Missile Development
