Abstract
An aerospace hybrid powertrain system includes an engine, a power shaft, and an electric machine having the power shaft therein or passing therethrough. The aerospace hybrid powertrain system further includes a fan, impeller, or blower connected to the power shaft and configured to direct air toward components of at least one of the engine or the electric machine. The fan, impeller, or blower may further be configured to direct air toward cooling elements such as heat exchangers or finned heat sinks arranged to cool the components of at least one of the piston combustion engine or the electric machine.
Claims28
An aerospace hybrid powertrain system comprising:
- a power shaft;
- an engine configured to output mechanical power via rotation of the power shaft;
- an electric machine having the power shaft therein or passing therethrough, wherein the electric machine is configured to generate electrical power based on the rotation of the power shaft, wherein the electrical power is output to a propulsion device of an aircraft;
- and
- a fan, impeller, or blower connected to the power shaft and configured to direct air toward:
- at least one component associated with the engine;
- and
- at least one component associated with the electric machine.
