Performance evaluation of LE-7 high-pressure pumps

Performance evaluation of LE-7 high-pressure pumps

The hydrodynamic performance of the high-pressure cryogenic propellant feed pumps of an LOX/LH2 engine, LE-7, is evaluated thermodynamically. The LOX pump is shown to have an efficiency of about 80 percent at the designed flow rate; the efficiency of the LH2 pump is estimated at 75 percent. Details...

Zusammenfassung:The hydrodynamic performance of the high-pressure cryogenic propellant feed pumps of an LOX/LH2 engine, LE-7, is evaluated thermodynamically. The LOX pump is shown to have an efficiency of about 80 percent at the designed flow rate; the efficiency of the LH2 pump is estimated at 75 percent. Details of the test procedure and the design parameters of the pumps are presented. (AIAA)
