Combined power system
An engine housing of a gas turbine engine includes a plurality of leg members. An air intake space is formed between the plurality of leg members. A shroud case supported by the engine housing is disposed in the air intake space. A rotary electric machine housing of a rotary electric machine system includes a rectifying member. The rectifying member includes a distal end facing toward the shroud case, and the distal end is inserted inside the shroud case.
1. A combined power system comprising:
a rotary electric machine system including a rotary electric machine, and a rotary electric machine housing in which a rotating shaft of the rotary electric machine is rotatably supported; and
a gas turbine engine including an output shaft configured to support a turbine wheel and a compressor wheel and rotate integrally with the rotating shaft, and an engine housing in which the turbine wheel and the compressor wheel are accommodated,
wherein the engine housing includes a plurality of leg members on one end thereof in an axial direction, the plurality of leg members are connected to one end of the rotary electric machine housing in an axial direction, and an air intake space is formed between the plurality of leg members,
the combined power system further comprises:
a rectifying member provided on the one end of the rotary electric machine housing in the axial direction, and disposed in the air intake space, the rectifying member being gradually reduced in diameter from the rotary electric machine toward the gas turbine engine; and
a shroud case supported by the engine housing and disposed in the air intake space, the shroud case facing toward the rectifying member, and
the rectifying member includes a distal end facing toward the shroud case, and the distal end is inserted inside the shroud case.
2. The combined power system according to claim 1 , wherein an outer wall of the rectifying member is a smooth surface.
3. The combined power system according to claim 1 , wherein one end of the output shaft in an axial direction is connected to one end of the rotating shaft in an axial direction, and a location where the rotating shaft and the output shaft are connected to each other is inside the rectifying member.
4. The combined power system according to claim 1 , wherein one end of the rotating shaft in an axial direction is inserted into one end of the compressor wheel in an axial direction, and the one end of the compressor wheel in the axial direction is inserted into the rectifying member.
