description abstractDescription of Driving Event:
In the SSME, a small recirculation flow is maintained by flowing the propellant through a bleed valve located at the main fuel valve to an overboard dump line or pumped back into the LH2 inlet. Recirculation flow of LOX is maintained by flowing LOX through a bleed valve located a the fuel preburner oxidizer valve to an overboard dump system. These recirculation flows have successfully eliminated gas pockets in the LH2 and LOX systems.
