Alex,
If the chamber pressure of Raptor is 300bar / ~30MPa / ~4500psi, wouldn't that
imply a much higher high-side pressure for the oxygen and the fuel component
that goes into the preburner? I don't know what sort of multiple of chamber
pressure is typical for the pump outlet pressure on FFORSC engines, but I had
usually heard 2-3x, which would imply something closer to 60-90 bar
(9000-14000psi). Could someone who actually knows turbopumps chime in?
Raptor's chamber pressure is 20-30% higher than most of the RD-170 family
engines.
