  • MACHINE WITH PARAMAGNETIC SHELL AND MAGNET
    Publication number: 20230261535
    Abstract: A machine includes a stator and a rotor that is rotatable with respect to the stator. The rotor includes a shaft that has a paramagnetic shell. The shell defines a cavity therein, and there is a magnet disposed in the cavity. The magnet is of complementary shape to the cavity such that the magnet and paramagnetic shell are rotationally interlocked.

  • Turbopump with axially curved vane
    Patent number: 11268515
    Abstract: A turbopump includes an impeller (22) that is rotatable about an axis (A). A discharge collector (28) is located radially outward of the impeller. A passage (30) fluidly connects the impeller to the discharge collector. The passage is curved.

  • Stepped slinger
    Patent number: 10907645
    Abstract: 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.

  • Turbopump machine with isolated cooling passage discharge
    Patent number: 10443438
    Abstract: 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.
