Abstract
A thrust reverser comprised of two pivoting doors for engines mounted on an aircraft rear fuselage. For thrust reversal, the two pivoting doors are rotated into the mixed flow by two actuators, one actuator per door. On the extremities of each pivoting door, efflux flow turning devices are installed. These devices are removable boxes comprised of deflectors that can be oriented to turn the flow. Two boxes are required for each pivoting door.
Claims3
A thrust reverser for a turbo-fan engine with mixed hot and cold airflow, said thrust reverser being mounted on the aft fuselage of an aircraft, the thrust reverser comprising:
- thrust reversing pivoting doors, installed forward of an aft ring exit nozzle structure, and movable from a stowed position in which they complete a fan duct fairing of the engine and do not interfere with said airflow to a deployed position in which they block the mixed airflow and direct it in a forward direction, according to a reverse thrust efflux pattern;
- a pivoting door actuator attached to the center of each pivoting door for moving the door from said stowed position to said deployed position;
- deflector box assemblies, on each door forward extremity, mounted perpendicularly to the door, in order to direct said reverse thrust efflux pattern away from the aircraft fuselage and tail surfaces, each deflector box assembly comprising:
- a box frame without front and back plates,
- a plurality of deflectors that pivot within the box frame and that can be oriented to a desired angle in order to control the efflux flow pattern.
