Abstract
An electric power system of a moving object includes a gas turbine engine including a compressor and a rotating electric machine connected to the gas turbine engine, a first bleed air flow path configured to introduce bleed air obtained by taking out a part of air compressed by the compressor into the rotating electric machine, and a second bleed air flow path configured to guide the bleed air introduced into the rotating electric machine to a component requiring cooling of the turbine engine.
Claims12
An electric power system comprising:
- a gas turbine engine including a compressor and a component requiring cooling;
- a rotating electric machine connected to the gas turbine engine;
- a first bleed air flow path configured to introduce bleed air obtained by taking out a part of air compressed by the compressor into the rotating electric machine;
- a second bleed air flow path configured to guide the bleed air introduced into the rotating electric machine to the component requiring cooling;
- an exhaust passage to which exhaust gas from the gas turbine engine is discharged;
- a bleed air lead-out flow path configured to allow the bleed air guided to the component requiring cooling to flow toward the exhaust passage;
- a radiator for taking heat from a cooling medium for cooling the rotating electric machine;
- a cooling air flow path configured to allow cooling air having cooled the radiator to flow toward the exhaust passage;
- and
- a mixing section in which the bleed air and the cooling air are mixed with each other,
- wherein mixed air obtained by mixing the bleed air and the cooling air is introduced into the exhaust passage from the mixing section.
