INTEGRATED THRUST REVERSER ACTUATION SYSTEM

摘要

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.

1. A turbofan engine comprising:
a turbine engine; a nacelle surrounding at least a portion of the turbine engine and defining an annular bypass duct between the nacelle and the turbine engine and extending through the turbofan engine to define a generally forward-to-aft bypass air flow path; a thrust reverser having at least one movable control surface, movable to and from a reversing position, where at least a portion of the bypass air flow is at least partially reversed; a thrust reverser actuation system having at least one actuator operably couple to the at least one moveable control surface to move the at least one moveable control surface into and out of the reversing position; and 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; wherein one of the rail and bogie is mounted to the turbine engine and the other of the rail and bogie is mounted 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.
