@flcnhvy @Erdayastronaut @Cor_SPACE Just SX500 so far, but we use many superalloys developed by others, eg Inco 718+. If anyone has 718++, that would be helpful haha. Massive engineering work in the casting, printing & machining of Raptor — far more than in design of the engine itself!

@Erdayastronaut @Cor_SPACE There’s so much power going through this engine that it’s close to the limit of the known physics of materials in many places

@Carter__99 @Erdayastronaut @askingbubble385 @Cor_SPACE Yes

@Erdayastronaut @Cor_SPACE Well, hopefully closer to 300 bar over time. However, that the chamber/nozzle jacket has so many joints & dissimilar metals at such high pressure & temperature is what I find remarkable about it.

@flcnhvy @Erdayastronaut @Cor_SPACE No, we’ve been focusing on production (now on SN12). Only need 250 bar or even a bit less for Starship/Super Heavy. Anything above 250 is nice to have & we’ll get around to it, but not needed for flight.

@NCBirbhan @Erdayastronaut @Cor_SPACE Probably around 6 or 7pm

@Erdayastronaut @Cor_SPACE What blows my mind is that peak pressure in regen chamber & nozzle is *far* above combustion pressure at over 800 bar or ~12,000 psi

@BrendanCogbill7 About a week. Will include slight improvements, based on initial user feedback.

@justpaulinelol We look for rare corner case issues with a limited release US build, then expand internationally as we receive approval from regulatory authorities. So, soon, but hard to say exactly.
