A great thing rocket lab has done is demonstrate the feasibility of electric fuel pumps which dramatically simplify rocket engine design. Raptor is a breakthrough work of art obviously but the Rutherford engine lowers the barrier to entry for at least beginning the propulsion conversation.
- adolph 6y agoThe idea of electric fuel pumps is certainly interesting and I guess it works for Rocket Lab, but the idea of tossing out batteries as you gain altitude [0] just feels wrong. Maybe batteries are an intermediate step to decoupling the fuel pump from the turbo part, like the M-B F1 tech [1]? 0. https://space.stackexchange.com/questions/24570/what-was-ejected-from-rocketlabs-electron-launch-vehicle-at-t625-during-stage https://space.stackexchange.com/questions/24570/what-was-eje... 1. https://www.thedrive.com/news/34152/how-mercedes-amg-will-use-electric-turbos-from-f1-to-kill-lag-in-road-cars https://www.thedrive.com/news/34152/how-mercedes-amg-will-us...
