A turbopump includes an impeller () that is rotatable about an axis (A). A discharge collector () is located radially outward of the impeller. A passage () fluidly connects the impeller to the discharge collector. The passage is curved.

Turbopump with axially curved vane

A turbopump includes a slinger that has a first section and a second section. The first and second sections are disposed substantially radially in a fluid circuit. The second section is downstream of, and radially inward of, the first section. A housing is located downstream and adjacent to the first section of the slinger and radially outward of the second section of the slinger.

Stepped slinger

A turbopump machine includes a housing, a shaft rotatably supported in the housing on a set of bearings, an axial pump coupled with the shaft, a circumferential discharge volute fluidly coupled with the axial pump, and a turbine coupled with the shaft. The turbine includes a blade row disposed in an axial turbine flowpath that has an axial turbine flowpath discharge that is fluidly coupled with the circumferential discharge volute. A cooling passage is disposed between the housing and the shaft about the set of bearings. The cooling passage has a cooling passage discharge that is fluidly coupled with the circumferential discharge volute. The cooling passage discharge is adjacent the axial turbine flowpath discharge. A seal isolates the cooling passage discharge from the axial turbine flowpath discharge.
