Recently, India-based defence start-up D-Propulse announced that it had successfully demonstrated a rotating detonation engine at a Defence Research & Development Organisation facility in Hyderabad.

About Rotating Detonation Engine 

  • It is a type of propulsion system that differs from conventional gas turbines and ramjets in the way it uses fuel. 
  • Usually, engines use deflagration, which is a subsonic, steady way of burning fuel through a flame. 
  • On the contrary, an RDE uses detonation, wherein the fuel burns faster as rapid supersonic explosions rotate through the chamber of the engine. 
  • This rapid detonation produces more thrust for the same amount of fuel.  
  • This volume savings can be used to increase fuel and/or payload volume, providing potential range, speed, and affordability benefits compared to rockets, ramjets, and gas-turbines. 
  • These mechanically simple RDEs have no moving parts, making them less complex than gas turbine engines and therefore potentially lower cost and simpler to manufacture.
