In a nozzle reverser assembly for a gas turbine engine, a swinging vane pack reverser is provided in place of the prior art array of cascade vanes in reverser ports of such engines. The present invention includes a door flap that is hinged on the aft side of a reverser port, which door flap has sidewalls attached thereto that extend into such port. The reverser assembly of the invention also includes a vane pack that is hinged at the forward end of such reverser port and has a roller attached its aft end, which roller engages a track within the door flap for sliding engagement therewith. Forward of the vane pack hinge, a boundary layer trip fence is hinged to the engine housing. In operation, air flow directed into the reverser cavity, e.g. by a convergent flap, is guided further by the above door flap and its sidewalls. The flow then passes through the longitudinally disposed vanes of the vane pack, which pack extends across the reverser port and between the door flap and trip fence, which in their open position, extend forward at acute angles with such engine, to define an external reverser channel therefor. The boundary layer trip fence prevents the gas exiting the reverser from traveling up the air frame boundary layer while the vane pack provides for lateral vectoring to prevent reverser gas flow from impinging on aircraft control surfaces. Thus, reverser flow can be directed from an engine at desired pitch and splay angles and at reduced flow blockage through such vanes.

A reverser assembly for a nozzle of a gas turbine engine which has internal reverser flaps comprising, a reverser opening on at least one side of the nozzel, a forward door and a rearward door mounted over said opening having spaced-apart pivot points, which doors pivot toward each other into closed position and which pivot away from each other into an open position, projecting from the side of said engine to direct reverser gas flow away from said engine at a desired pitch angle in a fore and aft direction, a swinging vane pack pivotably mounted at one end proximate said forward door, between said pivot points, to said engine, said vane pack being mounted in sliding engagement at the other end thereof with said aft door so as to be swingably mounted across the reverser exhaust opening, which vane pack has a plurality of spaced vanes which can be oriented to splay reverser gas away from aircraft components in a laterally vectoring direction relative to said engine so as to provide multi-directional reverser flow control for said engine.
