Patent number: 11852083Abstract: An electronic controller for an engine and a propeller, a control system and related methods are described herein. The control system comprises the controller having a first channel and a second channel independent from and redundant to the first channel. Each channel comprises a control processor configured to receive first engine and propeller parameters and to output, based on the first engine and propeller parameters, at least one engine control command and at least one propeller control command. Each channel also comprises a protection processor configured to receive second engine and propeller parameters and to output, based on the second engine and propeller parameters, at least one engine protection command and at least one propeller protection command. The control system comprises sensors for measuring the parameters of the engine and/or the propeller and effectors configured to control the engine and the propeller.Type: GrantFiled: June 30, 2022Date of Patent: December 26, 2023Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Jasraj Chahal, Brant Duke, Carmine Lisio, Jim R. Jarvo, Giancarlo Zingaro

Patent number: 10899433Abstract: A system and method for feathering an aircraft propeller are provided. A first feather solenoid and a second feather solenoid each comprising at least one solenoid coil and a solenoid valve coupled to the actuator and to the at least one solenoid coil are provided. At least one controller is configured to selectively energize and de-energize the at least one solenoid coil. The solenoid valve of the first feather solenoid is configured to be activated when the at least one solenoid coil of the first feather solenoid is energized and the solenoid valve of the second feather solenoid is configured to be activated when the at least one solenoid coil of the second feather solenoid is de-energized. The solenoid valve is configured to, when activated, modulate the supply of hydraulic fluid to an actuator for adjusting a blade pitch of the propeller towards a feather position.Type: GrantFiled: July 10, 2018Date of Patent: January 26, 2021Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Jasraj Chahal, Carmine Lisio, Jim R.
