Problems solved by technology

Since the engine needs to be running during cleaning, the design of the nozzle is short, and the penetration channel is relatively shallow. For the inner part of the channel, a limited number of spray angles are used to clean the blades, so the cleaning is not sufficient

Abstract

The invention relates to the technical field of aircraft engine casing design, and particularly provides an aircraft engine strength bearing casing with a washing function. The aircraft engine strength bearing casing is provided with a plurality of stator blades. The multiple stator blades are located on the front side of a rotor blade, the stator blades are internally provided with cavities, and the exteriors of the stator blades are connected with a washing device through flanges. The washing device communicates with the cavities, the tail edge of each stator blade is provided with a plurality of cleaning fluid outlets in the radial direction, the cleaning fluid outlets communicate with the corresponding cavities, the cleaning fluid outlets penetrate the corresponding stator blades, and washing of the rotor blade is achieved by rotating the rotor blade and spraying cleaning fluid towards the rotor blade from the cleaning fluid outlets.

Description

technical field [0001] The invention relates to the technical field of aircraft case design, in particular to a load-bearing case of an aircraft engine with a cleaning function. Background technique [0002] After the engine is used for a period of time, foreign matter in the air such as oil dirt will be deposited on the blade surface, which will thicken the blade profile and reduce the engine efficiency. [0003] In order to avoid the situation of the engine returning to clean the blades caused by this, a cleaning equipment installation device is installed at the engine inlet. After the engine has been used for a period of time, the cleaning device is installed. Clean the rotor blades according to the test program, remove the foreign matter deposited on the blade surface, and then remove the cleaning nozzle from the engine after cleaning, and block the hole on the casing with a plug. Since the engine needs to be running during cleaning, the design of the nozzle is relative...
