Abstract
Systems and methods associated with electrical systems of aircraft are disclosed. A method disclosed herein comprises generating electricity using an electric generator operatively coupled to an engine of the aircraft, supplying the electricity generated using the electric generator to a baseline power bus; generating electricity using an electric starter generator operatively coupled to the engine; and supplying the electricity generated using the electric starter generator to a supplemental power bus independent from the baseline power bus.
Claims28
An electrical system for a specialized aircraft, the system comprising:
- an electric generator operatively coupled to an engine of the aircraft;
- a baseline power bus configured to distribute electricity to one or more baseline electric loads, the electric generator supplying electricity to the baseline power bus when the electric generator is driven by the engine;
- an electric starter generator operatively coupled to the engine, the electric starter generator being configured to operate as a motor to start the engine and to operate as a generator when driven by the engine;
- and
- a supplemental power bus configured to distribute electricity to one or more supplemental electric loads different from the one or more baseline electric loads, the supplemental power bus being independent from the baseline power bus, the electric starter generator supplying electricity to the supplemental power bus when the electric starter generator is driven by the engine.
A method of operating an electrical system of a specialized aircraft, the method comprising:
- generating electricity using an electric generator operatively coupled to an engine of the aircraft;
- supplying the electricity generated using the electric generator to a baseline power bus;
- generating electricity using an electric starter generator operatively coupled to the engine;
- and
- supplying the electricity generated using the electric starter generator to a supplemental power bus independent from the baseline power bus.
A method for increasing an electric generating capacity of an aircraft comprising an engine, an air-powered starter for starting the engine and an electric generator configured to be driven by the engine and supply electricity to a first power bus, the method comprising:
- uncoupling the air-powered starter from the engine;
- operatively coupling an electric starter generator to the engine for starting the engine;
- adding a second power bus to the aircraft, the second power bus being independent from the first power bus;
- and
- configuring the electric starter generator to be driven by the engine and supply electricity to the second power bus.
