US 10,851,734 B2 · Thrust reverser assembly

Abstract

A thrust reverser assembly for high-bypass turbofan engine. The thrust reverser assembly includes a translating cowl mounted to a nacelle of an engine. The thrust reverser assembly includes blocker doors axially guided adjacent first ends thereof by a fixed structure and pivotally and slidably connected along lengths thereof to an inner wall of the translating cowl so that translation of the translating cowl in the aft direction causes the blocker door to move from a stowed position to a deployed position. The thrust reverser assembly includes a stop disposed on the core engine or on the blocker door, receiving the load from the high pressure airflow, otherwise borne by an actuation system when deploying the translating cowl and blocker door.

Dependent claims

A gas turbine engine, comprising:

a core engine;
a nacelle surrounding at least a portion of the core engine;
a bypass duct defined by and between the nacelle and the core engine and defining a fore-to-aft air flow conduit;
a cascade element located within the nacelle;
a blocker door movable between a stowed position, where the blocker door closes the cascade element to the air flow conduit, and a deployed position, where the blocker door opens the cascade element to the air flow conduit and a longitudinal end of the blocker door extends into the air flow conduit to deflect air through the cascade element;
an actuator mechanically coupled between the blocker door and the nacelle and configured to selectively move the blocker door between the stowed position and the deployed position;
and
a stop located on the core engine at a position where the longitudinal end of the blocker door abuts the stop in the deployed position, wherein any aerodynamic loading on the blacker door is shared through the actuator and the stop, and the stop protrudes into the bypass duct when the blocker door is in the stowed position.
