Engineering / Re: Interesting stuff about SpaceX Starship (hate the name)
« Last post by Nemesis on Today at 03:16:38 pm »One further observation I have. The exhaust streams from all 3 starship hops are very tightly collimated even the SN8 with 3 engines. I thought it unusual so watched videos of Falcons1 and 9, Electron (Rocket Labs), shuttle and Saturn 5 launches and those launches have a much more diffuse exhaust. Could this be part of the increased efficiency of Raptors? Wonder if it will apply to the vacuum engines
The recent (sub orbital) test by Blue Origin with 1 engine also had a more tightly collimated exhaust. Not as tight as the 1 and 3 engine Raptor hops done by Starship but much more so than the others I looked at.
