Turbopumps spinning at tens of thousands of revolutions per second.
This is actually not true. These turbopumps are quite large and spin fairly slowly. The design RPM on the F-1 turbopump appears to have been 5500 RPM, for example. (That's not to say they aren't complicated, because they were using 55,000 horsepower to push the propellants into the engine.)
- elteto 6y agoNot all of them! The Merlin turbopump spins at a whopping 36k RPM! [0] https://en.m.wikipedia.org/wiki/SpaceX_Merlin#Turbopump https://en.m.wikipedia.org/wiki/SpaceX_Merlin#Turbopump
- twicetwice 6y agoYup, that's what I was thinking of... I learned most of what I know about rockets from /r/SpaceX and related places! :)
- lutorm 6y ago36,000 RPM is 600 RPS, which is still aways off from "tens of thousands".
- twicetwice 6y agoOops, you're totally right, I messed that up. Too late to edit the parent unfortunately. I think it's certainly still impressive, though!
