Want to know how @SpaceX's Raptor engine works? Confused about what the full flow staged combustion cycle is? Why are they using methane? How's the Raptor compare to other rocket engines? My deep rundown on the Raptor is finally up! Great engine @elonmusk youtu.be/LbH1ZDImaI8

Great video. Couple notes: Raptor designed for subcooled CH4/O2, so propellant density & thrust increase up to ~8%, as needed for mission. 380 Isp & up to 50% thrust/weight improvement over time. Merlin thrust/weight doubled from V1, but Raptor is closer to optimum.
