Fly-by-wire engine power control system

摘要

According to one embodiment, a method of managing pilot and copilot control of engine power in an aircraft includes receiving, from a first pilot input device, a first signal representative of a pilot selection of an increase power position or a decrease power position and receiving, from a second pilot input device, a second signal representative of a pilot selection of an increase power position or a decrease power position. One of the first signal and the second signal is prioritized. An aircraft engine is then instructed to change power output based on the prioritized signal.

主权项

1. A rotorcraft, comprising:
a body; a power train coupled to the body and comprising an engine and a drive shaft coupled to the engine; a main rotor system coupled to the power train, the main rotor system comprising at least one main rotor blade; a pilot input device disposed within the body and comprising:
an engine power throttle adjustable among a neutral position, an increase position, and a decrease position, the pilot input device configured to transmit a first signal in response to a pilot selection of the increase position and transmit a second signal in response to a pilot selection of the decrease position;a shaft coupling the engine power throttle to the body of the rotorcraft; anda transmission wire disposed within the shaft and configured to electrically communicate signals from the engine power throttle to an engine control unit; and the engine control unit in electrical communication with the engine power throttle and operable to:
instruct the engine to increase power output in response to receipt of the first signal via the transmission wire; andinstruct the engine to decrease power output in response to receipt of the second signal via the transmission wire.
