Basic Information

The Raptor engine is a full-flow staged combustion cycle engine developed by SpaceX. It uses liquid methane (CH4) as fuel and liquid oxygen (LOX) as oxidizer also known as METHALOX. 

• TWR:  1:200
• Chamber pressure 300 bar
• Thrust: 880–2,210 kN sl, 8200 kN vac
• Nozzle ratio: 40
• Mixture ratio: 3.55 (78% O2, 22% CH4)
• Specific impulse: 382s vac, 334s sl​

[These numbers might change as the engine is currently being developed and improved]
