Orbital Liquid Oxygen Pump, Phase I

This proposed work will develop a pump, which is based on two novel and unique design features. The first feature is a lobed pumping mechanism which operates with orbital motion. The second feature is the novel manner in which the orbital motion is generated. This pump has monolithic construction, is intrinsically sealed, and mechanically balanced. Power is provided to the pumping mechanism by electromagnetic drives, which are incorporated into the pump mechanism forming a compact, integrated unit. The unique features and simplicity of this design promises to provide a pump, which is compact, has low mass, and has quiet, safe, and reliable operation. This pump will be ideal for the long-term, space-based applications. Its development will focus on cryogenic fluids pumping including liquid oxygen. More »
