Abstract
Aspects of the disclosure generally relate to an aircraft propulsion system for an aircraft. The aircraft propulsion system can include at least an electric power source, an electric machine, a voltage regulator, and at least one propeller. The voltage regulator regulates the electrical power provided to the electric machine from the electrical power source. The electric power source is capable of providing an AC or DC electrical output and can include a combustion engine with a generator or an electrical storage device.
Claims20
An aircraft propulsion system for an aircraft, comprising:
- a propeller;
- an electric machine configured to operably rotate the propeller;
- an electrical power source having a power output and configured to provide electrical power to the electric machine;
- and
- a voltage regulator configured to regulate the electrical power at the power output by controlling the voltage provided to the electric machine as a function of ambient air pressure in at least one portion of the aircraft.
A method of operating an electric distribution system having an electrical conductor supplying electricity to an electric machine rotationally driving a propeller in an aircraft, the method comprising:
- sensing ambient air pressure of the electrical conductor;
- and
- controlling the voltage at the electrical conductor based on the sensed ambient air pressure.
