Rotating Detonation Rocket Engine (RDRE)

  • YouTube: How NASA Reinvented the Rocket Engine | Real Engineering
    • A flame front travel through the fuel mixture in the engine's combustion chamber
      • Deflagration: the flame front travels slower than the speed of sound (current rocket engines)
      • Detonation: the flame front travels faster than the speed of sound
    • Rotating detonation: the flame front rotates around the circumference of the chamber without pulses
    • Pros/Cons: Higher efficiency and higher thrust, but still unstable and hard to simulate the chaotic flow
    • CRCop-42 Copper: alloy that can cope with the high fluctuation of temperature and pressure, and can be 3D printed
    • Aero spike nozzle can improve the engine's efficiency over a range of altitude, i.e., a range of atmospheric pressure
