minus-squarethreelonmusketeers@sh.itjust.workslinkfedilinkEnglisharrow-up0·4 months ago The only actual metric they quoted is exhaust speed? Not saying we shouldn’t be skeptical, but isn’t that the most important metric? A crazy-high exhaust velocity is how you get an engine with crazy-high specific impulse.
