Coking rocket engine
WebWhile methalox will resolve the coking issue. I am very sceptical that SpaceX will see overall reduced costs with Starship as it has 6x the engines as a Falcon 9. IMO the rocket that has learned the most from Falcon 9 in its design is Rocket Lab’s Neutron. They looked at the weaknesses that Falcon 9 had and worked to resolve them. Web1) When heating the propellant, beware that it will be VERY hot. On top of it being hot, it may still be sticky and painful to get off. 2) I suggest using goggles for anything that you …
