THRUST REVERSER WITH BLOCKER DOOR FOLDING LINKAGE
20200400098 · 2020-12-24 ·

An assembly is provided for an aircraft propulsion system. This assembly includes a fixed structure, a translating structure, a blocker door and a folding linkage. The translating structure is configured to move between a stowed position and a deployed position. The blocker door is pivotally attached to the translating structure at a first pivot joint. The folding linkage links the blocker door to the fixed structure. The folding linkage includes a member pivotally attached to the blocker door at a second pivot joint that is radially outboard of a skin of the blocker door when the translating structure is in the stowed position. The second pivot joint is radially outboard of the first pivot joint when the translating structure is in the stowed position.

THRUST REVERSER CASCADE AND METHOD OF MANUFACTURE
20200392923 · 2020-12-17 ·

A thrust reverser cascade of an aircraft engine comprises a frame and a vane overmolded onto the frame. The frame and the vane each comprise reinforcement fibers in a thermoplastic matrix. A method is disclosed for manufacturing the thrust reverser cascade or another part comprising an aerodynamic surface configured to interact with a flow of fluid. The method comprises providing a first portion of the part and overmolding a second portion of the part onto the first portion where the second portion includes the aerodynamic surface.

Hidden linkage for a translating cowl thrust reverser

A system and method for an improved thrust reverser is provided. The provided thrust reverser employs hidden linkage assemblies to decrease drag in the engine exhaust flow and increase turbine engine performance. The hidden linkage assemblies are placed in a space between the blocker door and the transcowl, thereby not affecting the engine exhaust flow.

Composite translating cowl assembly for a thrust reverser system

An improved translating cowl (transcowl) assembly for a thrust reverser system for a turbine engine is provided. The transcowl assembly comprises an outer skin comprised of a first composite material and an inner skin comprised of a second composite material. The inner skin is configured to couple circumferentially within the outer skin and creates a flow path for engine exhaust flow. The inner skin comprises a contoured depression configured to provide clearance for movement of a blocker door. A metallic bracket is disposed between the inner skin and outer skin.

MEMBRANE THRUST INVERTER FOR AN AIRCRAFT PROPULSION UNIT

An improved thrust reverser for an aircraft propulsion assembly includes redirection of the air flow for performing the thrust reversal by one or more closure membranes, i.e. by thin and flexible structures deployed across the propulsion assembly. The improved thrust reverser includes at least one closure membrane arranged to deflect at least one portion of the air flow in the direction of the evacuation structure when the thrust reverser is in the reverse jet position and an intermediate structure movable in rotation relative to the fixed structure.

Variable area nozzle assembly and method for operating same
11867136 · 2024-01-09 · ·

A variable area nozzle assembly for a gas turbine engine includes a fixed structure including a first fixed ring and a second fixed ring. The second fixed ring is spaced axially aft from the first fixed ring to define a first portion of an ejector passage therebetween. A nozzle defines an inner radial exhaust flow path surface. The nozzle includes a forward ejector door and an aft ejector door. The forward ejector door and the aft ejector door define a first surface portion of the inner radial exhaust flow path surface. Each of the forward ejector door and the aft ejector door are pivotable between respective closed positions and respective open positions. A translating ejector sleeve is mounted within the fixed structure and configured to axially translate within the fixed structure between a first axial position and a second axial position.
