Abstract:
1. A thrust reverser system for a gas turbine engine comprising: a duct including a cowling movable between an open position and a closed position by a door actuator in a direction transverse to a centerline of the gas turbine engine; a thrust reverser supported within the cowling and movable between an axial closed position, an axial intermediate position and an axial open position, wherein a portion of the thrust reverser engages a radially outboard portion of the duct when the thrust reverser is in the axially closed position; an input powering a thrust reverser actuator for moving the thrust reverser to the axial intermediate position; a controller commanding movement of the thrust reverser actuator and the door actuator, wherein the thrust reverser actuator is actuateable to move the thrust reverser from the axial closed position to the axial intermediate position such that the cowling is free to move responsive to the door actuator to the open position; and a user interface accessible outside of an aircraft including the gas turbine engine, the user interface for operating the controller to move the thrust reverser from the axial closed position to the axial intermediate position, wherein the cowling is movable to the open position when the thrust reverser is in the axial intermediate position and the user interface is further configured to operate the controller to activate the door actuator to move the cowling to the open position when the thrust reverser is in the axial intermediate position.
