Abstract: A comprehensive operational characterization of a representative, liquid hydrogen (LH2) aircraft engine pump, a key enabler for future hydrogen aviation, is presented in this work. The implications of leakage flows are ...

Abstract: Gear pumps are largely employed in aero-engine fuel systems to provide the combustor with fuel at adequate pressure and flowrate. The radial load applied on the gears, as a consequence of the pump pressure rise, is entirely ...
