minus-squarethreelonmusketeerslinkfedilinkEnglish3•6 days 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.
minus-square@SkybreakerEngineerlinkEnglish3•5 days agoFuel type, specific impulse, thrust, power consumption, engine mass and volume…
minus-square@[email protected]linkfedilink3•edit-25 days agoI would argue that fuel consumption would be quite important, same with power usage. Edit: and also exhaust mass. If it’s 1g of mass exhausted then it’s a moot point.
