    摘要： The subject matter of this specification can be embodied in, among other things, an engine assembly includes a nacelle configured to at least partially surround an engine, and a thrust reverser coupled to the nacelle, the thrust reverser having a thrust-reversing element movable relative to the nacelle between a stowed position and a deployed position, a hydraulic actuator operably coupled to move the thrust-reversing element between the stowed position and the deployed position, and a fluid control system configured to operate the hydraulic actuator, the fluid control system having an electrohydraulic servo valve operable to selectively route fluid between a pressurized fluid source, the hydraulic actuator, and a fluid return reservoir, and a bypass fluid line providing fluid communication between the hydraulic actuator and the fluid return reservoir independent of the electrohydraulic servo valve.

    摘要： A multiphase fuel injector has an injector body with a fuel inlet at a first end and a fuel outlet at a second end opposite the first end. A primary circuit disposed proximate the fuel inlet extends into a central portion of the injector body. The primary circuit is configured to receive a first flow of pressurized fuel from the fuel inlet that discharges into a spin chamber in the injector body downstream from the fuel inlet. The primary circuit is configured to impart a swirling action to the first flow of pressurized fuel. A secondary circuit is located in the injector body radially outward from the primary circuit. The secondary circuit is configured to receive a second flow of pressurized fuel from the fuel inlet that discharges into the fuel outlet. The secondary circuit is configured to impart a swirling action to the second flow of pressurized fuel.

    摘要： The subject matter of this specification can be embodied in, among other things, a torque motor monitoring system that includes a first observer module configured to receive a first collection of operational information about a torque motor when the torque motor is operating normally, and determine a duty offset ratio value based on the first collection of operational information, a second observer module configured to receive a second collection of operational information about a torque motor, determine a MOSFET gate duty ratio value based on the second collection of operational information and the duty offset ratio value, and determine a motor current value, and a fault detection module configured to identify a fault in the torque motor based on the MOSFET gate duty ratio value, the motor current value, and a predetermined fault determination threshold value.

    摘要： The subject matter of this specification can be embodied in, among other things, a linear actuator lock apparatus having a housing having an inner surface defining an axial cavity having a first housing portion where the axial cavity has a first lateral size, a second housing portion having a second, larger lateral size, and a face from the first housing portion to the second housing portion, a lock assembly having a lock carrier configured for movement within the cavity between a first position and a position, and a lock finger affixed to and extending away from the lock carrier, where the second finger end is configured to contact the face when extended and fit within the first housing portion when retracted, and a sleeve configured to move between a position in which the lock finger is permitted to extend and a position configured to contact and retract the lock finger.
