The upper limit of the velocity of the explosions is stated as 5600 mph, which is 2500 m/s, and less than the 3000 m/s exhaust velocity on a Falcon 9 engine. Why is this useful?
- Gravityloss 4y agoThis speed of the detonation front has nothing to do with exhaust velocity. This is a replacement for the combustion chamber sort of. The throat and nozzle accelerates the propellants.
- hinkley 4y agoIf memory serves the Raptor 2 has a diminished ISP in order to improve peak thrust. They widened the throat in order to push more power through it.
- UltraViolence 4y agoRaptor also trades efficiency for durability. Methane is much cleaner burning than kerosene (RP-1) and leaves no soot inside the engine. Important if you want to reuse it!
