Abstract
For a rotary electric machine housing, a cooling jacket and compressed air flow passages are formed on an outer circumferential side of the cooling jacket. On an outer side wall of the rotary electric machine housing, a terminal casing is formed and electric terminal portions are accommodated in the terminal casing. Air bleed ports are formed in a shroud case of a gas turbine engine. Compressed air that is compressed by a compressor wheel flows into the air bleed ports. The compressed air that has passed through the air bleed ports flows through air bleed passages formed in an engine housing and the compressed air flow passages. Then, the compressed air reaches the terminal casing.
Claims8
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,
- the combined power system further comprising a terminal casing disposed on an outer side wall of the rotary electric machine housing and in which electric terminal portions are accommodated, the electric terminal portions being configured to transmit and receive electrical power between the rotary electric machine and an external device,
- wherein an air bleed port is formed in a shroud case that surrounds the compressor wheel, and compressed air that is compressed by the compressor wheel flows into the air bleed port,
- an air bleed passage is formed in the engine housing, and the compressed air that has passed through the air bleed port flows through the air bleed passage,
- a cooling jacket is provided for the rotary electric machine housing, a compressed air flow passage is formed on an outer circumferential side of the cooling jacket, and the compressed air that has flowed through the air bleed passage flows through the compressed air flow passage, and
- the terminal casing is disposed on a downstream side of the compressed air flow passage.
