WebLiquified Natural Gas (LNG) is one of the most promising propellant for near future space transportation rocket engine because of its low cost and fewer handling concerns. However, for LNG propellant, erosion of engine material by sulfur (sulfur attack) and coking by LNG pyrolysis are significant problems in a regenerative cooling passage. In this … 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.
