Rotodynamic fluid transfer and energy extraction device with shaftless rotational coupling and constraint as used in rocket propulsion systems

Abstract

Turbopump assemblies and pump turbine assemblies utilized in rocket propulsion systems or other systems are disclosed. The turbopump assembly may include a rotor with at least one integral pump impeller and at least one integral turbine impeller, a housing containing the rotor, and first and second bearings supporting the rotor. The first and second bearings are supported by the housing. The rotor is disposed between the first and second bearings such that the at least one integral pump impeller and the at least one integral turbine impeller are supported between the first and second bearings. At least one integral pump impeller and at least one integral turbine impeller are provided between all bearings supporting the pump and turbine in the housing.
