Indian Startup Tests Indigenous Rotating Detonation Engine for Defence Use
Delhi-based startup D-Propulse has successfully tested an indigenous rotating detonation engine (RDE) at a DRDO facility in Hyderabad, achieving Technology Readiness Level 5. The RDE uses rapid supersonic explosions to generate more thrust with less fuel compared to conventional engines, potentially offering a cheaper, more efficient propulsion system. Experts highlight that developing such technology could enhance India's strategic autonomy by reducing reliance on foreign engine suppliers for maintenance and upgrades. Globally, similar RDE technology remains in testing phases without operational deployment.
