    摘要: Three vectoring ring support and actuation apparatuses are disposed in an equi-angular manner circumferentially about the engine casing. Each of the vectoring ring support and actuation apparatuses includes a vectoring ring means to transfer side loads from the vectoring ring to the engine casing, a vectoring ring translation means for allowing the ring to be translated, and a support pivoting means and ring gimballing means to allow the vectoring ring attitude adjustments by a set of linear actuators. The vectoring ring support apparatus transfers side loads acting on a vectoring ring and generated by a gas turbine engine thrust vectoring nozzle to a relatively stationary portion of the engine and allows tilting of the vectoring ring to vector the thrust of the nozzle. Each linear actuator is connected by a slider bar to the vectoring ring, a first actuator joint connects the linear actuator to a forward end of the slider bar, and an aft actuator joint connects an aft end of the slider bar to the vectoring ring. The aft actuator joint preferably is a ball joint having three rotational degrees of freedom and the forward actuator joint is preferably a clevis joint.

    摘要: An aircraft gas turbine axisymmetric vectoring nozzle has an interface ring centered about a nozzle, a vectoring ring disposed radially inwardly of and apart from the interface ring, and a bearing radially disposed between the vectoring ring and the interface ring. The bearing may be a sliding bearing having a sliding interface between the vectoring ring and the interface ring and the sliding interface is spherical. The bearing may be constructed of sliding bearing segments having sliding interfaces between the vectoring ring and the interface ring and the sliding interfaces are spherical. Each of the bearing segments includes an outer sliding element attached to the interface ring, an inner sliding element attached to the vectoring ring, and spherically curved outer and inner sliding surfaces on the outer and inner sliding elements respectively wherein the spherically curved outer and inner sliding surfaces define the sliding interfaces between the vectoring ring and the interface ring.

    摘要: A flap and seal positioning apparatus for centering adjacent longitudinally extending seals and flaps in the divergent section of an aircraft gas turbine engine axisymmetric vectoring nozzle and for equidistantly spacing the flaps during vectoring. The positioning apparatus provides a plurality of pivotably interlinked levers, preferably linked by universal joints, rotatably mounted on and about centering posts extending radially outward from the backs of the divergent flaps and seals. In one embodiment the flap levers have separate arms that are rotatably linked by a double hinge joint at their common centering post such that the arms rotate freely about an axis parallel to the divergent flap. Another embodiment provides the seal lever with a means to translate freely along its axis of rotation coincident with the centering post upon which it is mounted and has a two part centering post with an inner piston that slides within an outer cylinder.

    摘要: A vectoring ring support and actuation apparatus is provided for transferring the side loads acting on a vectoring ring and generated by a gas turbine engine thrust vectoring nozzle to a relatively stationary portion of the engine and tilting the vectoring ring to vector the thrust of the nozzle. The apparatus includes an axially pivotable first link pivotably mounted on a relatively stationary first portion of the engine, an axially pivotable second link pivotably supported by and connected to the first link, and a vectoring ring connected to an aft end of the second link. An actuator is operably mounted between a relatively stationary second portion of the engine (spaced axially apart from the stationary first portion of the engine) and the second link to axially pivot the first link with respect. Preferably a first joint links the actuator to the second link and has at least first and second rotational degrees of freedom with corresponding first and second perpendicular axes of rotation. A second joint may be used to pivotably connect the second link to the first link and has one rotational degree of freedom and a third axis of rotation co-linear with one of the first and second perpendicular axes of rotation. The first joint is preferably a ball joint having three rotational degrees of freedom.
