Double-duct turbine engine device

Abstract

The invention discloses a double-duct turbine engine device. The double-duct turbine engine device is used for washing an outer duct of a double-duct turbine engine and comprises a base, a top frame and a movable frame located between the base and the top frame. Guiding rods are slidably mounted on the periphery of the movable frame, the upper ends of the guiding rods are fixedly connected with the top frame, and the lower ends of the guiding rods are fixedly connected with the base. A first sliding groove with a leftward opening is formed in the movable frame, and a first sliding frame is slidably mounted in the first sliding groove. A rotating cavity with a leftward opening is formed in the first sliding frame, and a rotating block is mounted in the rotating cavity in a rotating fit mode. Fixing sleeves are fixedly mounted on the left end face of the rotating block in a vertically symmetrical mode. Rectangular grooves which communicate in the left-right direction are formed in the fixing sleeves. Sliding strips are slidably mounted in the rectangular grooves. Vertically-symmetrical reeds are fixedly mounted on the left end faces of the sliding strips, and flexible cleaning blocksare fixedly mounted at the ends, away from the sliding strips, of the reeds.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a double-duct turbine engine device. Background technique [0002] The full name of the turbofan engine is the turbofan engine (Turbofan), which is a kind of aircraft engine, developed from the turbojet engine (Turbojet). Compared with the turbojet, the main feature is that the first-stage compressor has a large area and is used as an air propeller (fan) to push part of the inhaled air back through the periphery of the jet engine. The part through which the air of the core part of the engine passes is called the inner duct, and the outer part of the core engine where only the fan air passes is called the outer duct, and the cleanliness of the inner wall of the outer duct determines the noise level during jetting to a certain extent. Therefore, The inner wall of the outer duct is often cleaned, and the traditional cleaning method is to manually insert the cleaning cloth into the ...

Problems solved by technology

The part through which the air of the core part of the engine passes is called the inner duct, and the outer part of the core engine where only the fan air passes is called the outer duct, and the cleanliness of the inner wall of the outer duct determines the noise level during jetting to a certain extent. Therefore, The inner wall of the outer duct is often cleaned, and the traditional cleaning method is to manually insert the cleaning cloth into the outer duct for operation, but this operation method has certain safety hazards, and the cleaning effect is poor and inefficient.
