Abstract
An electric propulsion system of an aircraft includes an electrical generator and a cooling device of the electrical generator. It further includes at least one thermoacoustic engine and a heat transfer circuit configured to transport heat dissipated by the electrical generator to the thermoacoustic engine. The cooling device of the electrical generator is at least partially powered by energy from the thermoacoustic engine.
Claims12
An electric propulsion system of an aircraft comprising:
- an electrical generator configured to dissipate heat during its operation,
- a cooling device of the electrical generator,
- the cooling device coupled to a turbine,
- at least one thermoacoustic engine, and
- a heat transfer circuit configured to transport the heat dissipated by the electrical generator to the thermoacoustic engine via a circulated heat transfer fluid, the heat transfer circuit comprising:
- a go duct configured to transfer the heat transfer fluid from the electrical generator to the thermoacoustic engine, and
- a return duct configured to return the heat transfer fluid from the thermoacoustic engine to the electrical generator, and
- wherein the turbine is at least partially rotated by energy from the thermoacoustic engine to at least partially drive the cooling device.
