A thrust reverser assembly may comprise a cascade of vanes and a sleeve configured to translate relative to the cascade of vanes. The sleeve may include an inner sleeve portion, an outer sleeve portion, and a pressure sleeve portion. The pressure sleeve portion may be located radially inward of the outer sleeve portion and may extend forward from the inner sleeve portion. A blocker door may be hingedly coupled to the pressure sleeve portion. A drag link may be pivotably coupled to the blocker door. A forward end of the drag link may be configured to deploy radially inward in response to aft translation of the sleeve.

In some embodiments, apparatuses are provided herein useful to sealing a gap between a movable flap and stationary structure, such as a gap between a gas turbine engine nozzle flap and sidewall. An apparatus for sealing such a gap may be a plunger seal which may include a plurality of plunger segments connected together using at least one flexure. When positioned in the gap, the flexures within the plunger segments pivot allowing rotation of each of the plurality of plunger segments about their respective pivot point, such that the plunger assembly seals and contours against the movable surface.

An assembly is provided for an aircraft propulsion system. This assembly includes a cowl door movable between a closed position and an open position. The cowl door includes a structural panel and a mount. The structural panel includes an inner skin, an outer skin and a cellular core. The cellular core is connected to and arranged between the inner skin and the outer skin. The mount includes a base and a coupler. The base is connected to and arranged between the inner skin and the outer skin. The coupler projects out from the base.

In some embodiments, apparatuses are provided herein useful to sealing a gap between a movable flap and a stationary structure, such as a gap between a gas turbine engine nozzle flap and a corresponding sidewall. An apparatus for sealing such a gap may be a dynamic skirted leaf seal which may include a flap arm and a wall arm opposite the flap arm. A distal end portion of the flap arm may comprise a first skirt and the distal end portion of the wall arm may comprise a second skirt that engages the first skirt. When positioned in a gap between the movable flap and the stationary structure, the skirted leaf seal may exert a force to urge the flap arm towards the flap and to urge the wall arm towards the structure to seal the gap.

A diaphragm latch may comprise a housing, a diaphragm disposed in the housing, a pin coupled to the diaphragm, an opening in the housing, and a pin aperture disposed in the first side, wherein the pin extends from the pin aperture. The diaphragm may be configured to move in response to a pressure being communicated through the opening, and the pin may be configured to at least one of extend or retract from the pin aperture in response to the diaphragm moving. The diaphragm latch may passively couple an inner fixed structure (IFS) to an intermediate case (IMC) during an overpressure event.

An assembly for an aircraft turbojet engine is described. The assembly includes a central gas-exhaust element and a connecting flange interposed between, upstream, a metallic outlet of a turbojet engine and, downstream, the central element. The connecting flange consists of an annular part and flexible lugs having axially: a first end where the lug is connected to the annular part, and a second free end, projecting radially outwards from the first end and towards which the lug is fixed with the central element.
