The F1 is a bigger (!!) version of the same engine. It's got the same crucial features:

1. turbo-pumps

2. the nozzle is cooled and the fuel warmed by making the nozzle out of tubes through which the fuel passed

3. holes drilled in the tubes so fuel leaked into the combustion chamber to provide boundary layer cooling

I think the pogo-ing was solved the same way, too - putting baffles in in various places.



By that logic essentially all cryogenic engines are “the same”.


In a similar vein, all modern jet engines can trace their core features back to the Ohain engine (not the Whittle engine).
