ABSTRACT:
A thrust reverser assembly is disclosed for a wing mounted gas turbine engine exhaust nozzle having a fixed outlet for discharging exhaust gases over a surface of the wing. The assembly in accordance with a preferred embodiment includes a deflector having forward and aft ends, and first and second sides joined together by a base. The deflector is positionable in a stowed position around the exhaust nozzle so that the aft end is disposed forward of the nozzle outlet for allowing substantially unobstructed discharge of exhaust gases therefrom, and in a deployed position for changing direction of exhaust gases for thrust reversal. Two pairs of first and second bellcranks are positioned adjacent to respective ones of the deflector sides and means are provided for rotating the bellcranks for moving the deflector between the stowed and deployed positions. The bellcranks control the angular orientation of the deflector so that the deflector aft end is disposed against the wing surface and the base extends outwardly from the wing surface for deflecting exhaust gases upwardly and out the deflector forward end when the deflector is in the deployed position.
