  • Integrated thrust reverser actuation system
    Patent number: 10161356
    Abstract: A turbofan engine having a turbine engine, a nacelle surrounding a portion of the turbine engine, and a thrust reverser. The thrust reverser comprises a movable control surface movable to and from a reversing position and a thrust reverser actuation system having at least one actuator operably coupled to the movable control surface to move the movable control surface into and out of the reversing position. A guide comprising a rail and a bogie having at least one rotatable bearing surface coupled to the rail for relative translational movement between the rail and bogie connects the turbine engine to the movable control surface such that operation of the at least one actuator moves the movable control surface by translation movement between the rail and the bogie.

  • INTEGRATED THRUST REVERSER ACTUATION SYSTEM
    Publication number: 20170342941
    Abstract: A turbofan engine assembly having a turbine engine and a nacelle that surrounds at least a portion of the turbine engine to define an annular bypass duct that defines a forward-to-aft bypass air flow path. The turbofan engine assembly further comprises a fixed portion and a movable portion which is movable in a direction along the bypass air flow path to an opened position that defines a thrust reversing outlet through which at least a portion of the bypass air flow may be directed. At least one actuator moves the movable portion to the opened position.
