Abstract

The invention discloses an engine mobile cover and an engine reverse thrust device, relates to the technical field of aero-engines, and solves the technical problems of complex structure and inconvenience for maintenance in the prior art. The engine mobile cover comprises a mobile cover body part, a reset mechanism and at least one blocking door, wherein a blocking surface is arranged on one side surface of the blocking door; the blocking door is movably connected with the mobile cover body part, and can rotate around the movable connection position to an opening position and a closing position relative to the mobile cover body part; and the reset mechanism is arranged between one side surface, opposite the blocking surface, of the blocking door and the mobile cover body part, and can apply enough reset force to the blocking door to rotate the blocking door from the opening position to the closing position. The engine reverse thrust device comprises a core engine hood, a blade grid component, a blade grid support ring, a driving mechanism and the engine mobile cover provided by the invention. According to the invention, the structure of the engine reverse thrust device is simplified and optimized.

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 ...
