摘要： Methods and systems for nacelle door electromechanical actuation may include a power distribution unit comprising a motor and differential gears; and a plurality of electromechanical actuators, each coupled to an output of a corresponding one of the differential gears. Each of the electromechanical actuators may include a configurable brake and a mechanical output, where the power distribution unit may provide mechanical torque to one of the electromechanical actuators via the motor and the differential gears based on configuration of the configurable brakes in each of the electromechanical actuators. At least one of the configurable brakes may be an electrically configurable brake. At least one of the configurable brakes may be a mechanically configurable brake. The differential gears may include two or more differential gears for receiving an input torque and supplying an output torque to one of a plurality of outputs of the differential gears.

摘要： An actuator converts linear motion into rotational motion. The actuator includes a power piston having a longitudinal axis. The power piston is configured to move back and forth along the longitudinal axis. A slider bearing is disposed within a cross-bore opening in the power piston. The cross-bore opening has a slider bearing axis orthogonal to the longitudinal axis. The slider bearing is configured to move back and forth within the cross-bore opening. An output shaft has a central axis orthogonal to both the longitudinal and the slider bearing axes. The output shaft includes an eccentric shaft pin inserted through a slot in the power piston and disposed within a cavity of the slider bearing. The eccentric shaft pin is offset from the central axis of the output shaft. The reciprocating movement of the power piston causes the slider bearing to move back and forth rotating the output shaft.

摘要： The present disclosure describes a propeller control unit (100) for controlling the blade pitch of a propeller. The unit includes an electrohydraulic servo valve (106) ("EHSV") and is connected to a propeller actuator (102) that adjusts the blade pitch of a propeller. The EHSV (106) operates to allow pressurized fluid to flow from a pressurized fluid source to the actuator (102) to adjust the blade pitch of the propeller in a flight pitch range and a ground pitch range, to allow pressurized fluid to flow from the source to the actuator (102) to adjust the blade pitch of the propeller in a flight pitch range but not a ground pitch range, and to block the flow of pressurized fluid from the source to the actuator and drain pressurized fluid from the actuator (102) to prevent adjustment of the blade pitch of the propeller in the flight pitch range or the ground pitch range.

摘要： A torch igniter (200) includes an auxiliary fuel injector (204); an ignition source (206); and an igniter body (202) carrying the auxiliary fuel injector and the ignition source. The igniter body (202) includes an auxiliary combustion chamber (210) having a side wall extending axially from a first end wall to a second end wall, the side wall defining an interior cavity between the first and second end walls. The igniter body (202) further includes a premixing cup (244) residing within the interior cavity including a cylindrical wall radially surrounding the auxiliary fuel injector and an auxiliary air inlet, the cylindrical wall of the premixing cup protruding axially outward relative to the first end wall of the auxiliary combustion chamber through a portion of the interior cavity to delineate a premixing zone radially inward of the cylindrical wall and a recirculation zone radially outward of the cylindrical wall.

摘要： A self-releasing lock mechanism is provided and is configured to lock a driveshaft that is in mechanical communication with a rotor to mechanical ground via a flange in a motor housing. The self-releasing lock mechanism includes a ground lock housing having a locking arrangement configured to selectively engage a second end of the rotor. Locking pins extend from the ground lock housing and are configured to pass through the flange region of the motor housing. A locking plate includes the driveshaft and locking sites that are adapted to selectively receive the locking pins. A biasing member is disposed between the ground lock housing and the flange region to bias the ground lock housing away from the flange region. The locking arrangement engages the second end of the rotor to overcome the bias from the biasing member when the locking pins are received in locking sites.
