Space Exploration Hydrogen Boost Pump

Concepts NREC proposes an electrically driven, boost pump, with an integrated motor to deliver liquid hydrogen saturated at 20 psia, at an increase in pressure of between 25 and 45 psid, and a flow rate of at least 0.6 kg/s. The target life will be 7500 hours with 3000 start/stop cycles. The boost pump can be used in conjunction with a high-pressure ratio pump for a variety of space exploration missions of interest to NASA. Because of differences in density, the hydrogen boost pump can be used for other fluids, such as LOX and methane, and satisfy are good portion of the flow and pressure rise needs for these propellants in launch and in-space applications. The pump will be designed with the intent to operate with other fluids to maximize its usefulness. The hydrogen pump development will enable more rapid development of other motor driven aerospace pumps for a variety of propellants and purposes for lower long term development costs.
