H02K 1/28

US Classification:

29598, 29607, 31015612, 31015622

Abstract:

A method for manufacturing a rotor assembly. The method includes providing a stub shaft having a first part and a second part, providing a magnet between the first part and the second part, and compressing the magnet between the first part and the second part using a connecting device. The method also includes drilling a hole through the first part and the magnet, cooling an inner shaft, and inserting the inner shaft into the hole.

Abstract:

A compressor ported shroud takes compressed air from the shroud of the compressor before it is completely compressed and delivers it to foil bearings. The compressed air has a lower pressure and temperature than compressed outlet air. The lower temperature of the air means that less air needs to be bled off from the compressor to cool the foil bearings. This increases the overall system efficiency due to the reduced mass flow requirements of the lower temperature air. By taking the air at a lower pressure, less work is lost compressing the bearing cooling air.

International Classification:

F01D 5/08

US Classification:

415 1, 415180

Abstract:

A turbomachine having gas cooled bearings may include an axially-oriented, cooling-gas passageway interconnecting first and second bearing chambers. The passageway may include grooves formed at an interface between an aerodynamic component of the turbomachine (e.g., a wheel or impeller) and a portion of a shaft assembly of the turbomachine.
