A thrust reverser for reversing a thrust of a turbofan engine of an aircraft. The reverser includes a pivot door, a cascade component, and an actuation system. The door is moveable between lowered and raised positions in which a side outlet is, respectively, covered and uncovered. The cascade includes turning vanes, and is moveable between forward and rearward positions in which the cascade is positioned, respectively, not over and over the side outlet. The actuation system deploys the reverser by simultaneously moving the door to the raised position and moving the cascade to the rearward position over the side outlet, and stows the reverser by simultaneously moving the cascade to the forward position and moving the door to the lowered position. When the door is raised and the cascade is over the side outlet, airflow through the side outlet is directed at least partially forward to provide reverse thrust.

A thrust reverser includes: a thrust-reversing element movable between a stowed position and a deployed position; at least one hydraulic actuator operably coupled to move the thrust-reversing element between the stowed and deployed positions; at least one hydraulic primary lock configured to transition, in response to a first activation pressure, between an engaged state, where movement of the thrust-reversing element is inhibited, and a released state, where movement of the thrust-reversing element is uninhibited; and a directional control unit fluidly coupled to the hydraulic actuator and the hydraulic primary lock, the directional control unit configured to transition from a first stage to a second stage in response to a second activation pressure that is greater than the first activation pressure, and where a transition from the first stage to the second stage by the directional control unit causes the hydraulic actuator to move the thrust-reversing element to the deployed position.

A pivot thrust reverser includes a first tandem pivot door subassembly comprising an inner panel and an outer panel. The inner panel and outer panel are connected by a first sliding rail. A second tandem pivot door subassembly is included comprising an inner panel and an outer panel. The inner panel and outer panel are connected by a second sliding rail.

One embodiment includes a pivot thrust reverser. The pivot thrust reverser includes a first tandem pivot door subassembly comprising an inner panel and an outer panel. The inner panel and the outer panel are connected so as to rotate simultaneously about respective pivot axes that are each positionally fixed axes relative to the gas turbine engine assembly. A second tandem pivot door subassembly is included, spaced from the first tandem pivot door subassembly and comprising an inner panel and an outer panel. The inner panel and the outer panel are connected so as to rotate simultaneously about respective pivot axes that are each positionally fixed axes relative to the gas turbine engine assembly.

One embodiment includes a pivot thrust reverser comprising a first tandem pivot door subassembly comprising an inner panel and outer panel connected. A second tandem pivot door subassembly is included comprising an inner panel and outer panel connected. Also included are a first actuator located on a first side of an attachment location to pivot the first tandem pivot door subassembly, a second actuator located on a second side of the attachment location to pivot the second tandem pivot door subassembly, and a third actuator located substantially radially opposite the attachment location to pivot both the first tandem pivot door subassembly and the second tandem pivot door subassembly. The first tandem pivot door is configured to be pivoted from stowed to deployed by the first actuator and the third actuator, and the second tandem pivot door is configured to be pivoted from stowed to deployed by the second actuator and the third actuator.

A cascade assembly of a nacelle for a turbofan engine includes a one-piece cascade fixed to a translating sleeve constructed and arranged to move between forward and aft positions along a centerline. A hook device of the cascade assembly includes a first catch fixed to a stationary structure and a second catch fixed to the one-piece cascade. The first catch is adapted to mate with the second catch for translating load when the cascade assembly is in a deployed state and the translating sleeve is in the aft position.
