@SciGuySpace Tank didn’t burst, but leaked at 7.6 bar. This is a good result & supports idea of 304L stainless being better than 301. We’re developing our own alloy to take this even further. Leak before burst is highly desirable. — PolitiTweet.org

@Peter_J_Beck @torybruno @Starlinksat223 @Erdayastronaut Yeah. Merlin, using a single pintle injector with cold, liquid propellant, needs a longer chamber than Raptor, which uses a large number of coaxial injectors, despite Merlin being less than half thrust. Propellant enters Raptor chamber as hot gas that’s already mixed. — PolitiTweet.org

@Mad_Maelstrom @Peter_J_Beck @torybruno @Starlinksat223 @Erdayastronaut Throttling is done by adjusting flow to the ox and fuel preburners. The lower limit of thrust is ox & fuel turbopump injector preburner “stiffness”, essentially when do the preburner elements start flaming out. — PolitiTweet.org
