- 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
