I would love to know how they prevented flow separation when they fired a vacuum optimized engine at sea level! Normally the pressure at the end of a vacuum nozzle is so low that the ambient air pressure will separate the flame from the nozzle and destroy the engine! @elonmusk

@Erdayastronaut Raptor has a very high chamber pressure, which in turn allows for a large expansion ratio nozzle without flow separation at sea level
@Erdayastronaut Currently at ~270 bar, but working on upgrades to get it over 300 bar
@elonmusk @Erdayastronaut What is going to happen to 2016 and 2017 teslas with fsd ? Will they get beta? Members are working on high safety scores.
@Erdayastronaut Got to 321 bar before RUD, but cause may be due to oxygen inlet pressure too low, rather than engine issues
@elonmusk @Erdayastronaut That's NUTZO-Awesome!
@elonmusk @All_That_Ash601 @Erdayastronaut I need upgrades, Elon
@elonmusk @Erdayastronaut i’ve had 100 for 2 days. more rollouts coming?
@elonmusk @Erdayastronaut I don’t know what all that means, but it’s all in good hands. SpaceX!!!! Also, looking forward to FSD Beta 10.3 tomorrow. Let’s go!!
@elonmusk @Erdayastronaut 300 bar would be the highest ever made right?
