Abstract

The invention discloses an engine movable cover and an engine thrust reverser, and relates to the technical field of aeroengines. The technical problem of complex structure and inconvenient maintenance in the prior art is solved. The movable hood of the engine includes a movable hood body, a reset mechanism and at least one choke door. One side of the choke door is provided with a choke surface. Rotate to the open position and the retracted position relative to the main body of the moving cover; the reset mechanism is arranged between the side of the choke door away from the choke surface and the main body of the moving cover, and the reset mechanism can exert sufficient force on the choke door to make the flow choke The return force for the door to rotate from the open position to the stowed position. The engine thrust reverser includes a core machine cover, a blade cascade assembly, a blade cascade support ring, a driving mechanism and the engine moving cover provided by the invention. The invention is used to simplify and optimize the structure of the engine thrust reverser.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to an engine movable cover and an engine thrust reverser provided with the engine movable cover. Background technique [0002] The engine thrust reverser is a device used to change the direction of the engine fan airflow to generate reverse thrust. When the aircraft lands normally, it can shorten the landing run distance of the aircraft on dry and slippery runways. [0003] In high bypass ratio turbofan engines, cold flow thrust reversers are usually used. The cold air flow reverse thrust device is a device that makes the low-temperature air flow that has not passed through the combustion chamber change its direction and sprays out to the side and front by mechanical baffle deflection or other methods, thereby generating backward reverse thrust for the engine or aircraft. . At present, relatively mature cold airflow thrust reversers are mainly divided into baffle door thrust ...
