Elon Musk Explains SpaceX's Raptor Engine!Today we’re getting up close and personal with SpaceX’s Raptor 2 engine with Elon Musk. We get into all sorts of details on this engine including how exactly it’s been upgraded and simplified compared to Raptor 1.This video has a ton of fun details on some fairly technical stuff, so be sure and watch my "Why don’t rocket engines melt" video - - so you know what we’re talking about with some of the cooling techniques as well as my video on engine cycles - - so you understand how the Raptor’s full flow staged combustion cycle works and why it’s advantageous!00:00 - Intro00:50 - Conversation Starts02:00 - Raptor 1 vs Raptor 203:50 - Thrust and Chamber Pressure05:30 - Iteration Philosophy06:30 - Melting Engines and Cooling09:30 - Torch Igniters and Starting13:00 - Full Flow Advantages15:30 - Swirl Injectors16:40 - Thrust Vector Control20:30 - Simplifications24:50 - Removing Throat Film Cooling25:35 - Boost Pumps and Impellers30:35 - Inline Powerhead Discussion32:15 - Fluorine, Dual Cooling and Aerospikes35:00 - Chamber Pressure and Impulse40:00 - Outro
