Web1 jun. 2024 · So you would need to add additional engines to the third stage, CSM, or LM. RP-1 is one of the dirtiest-burning rocket fuels, and can leave deposits in the engine. This makes it extremely unreliable to restart an engine. In contrast, hydrolox and hypergolic engines burn cleanly, and in the case of Apollo were used for re-ignitable engines. Web19 feb. 2016 · And probably a basic inline engine. I probably won't make any of them particularly big (aka, no 5m radius monster hypergolics) as it seems unlikely hypergolics would be used when the added complexity of turbopumps etc becomes so much less cumbersome.
