An aeroengine test system for simulating cloud environment

Abstract

The invention discloses an aero-engine test system for simulating a cloud environment, which relates to the field of aero-engines and includes an ice-making mechanism, a conveying mechanism, an experimental mechanism and a return mechanism. The ice-making mechanism includes a water tank, a water suction channel, an elastic membrane, a pumping plate and The ice-making module, the bottom plate of the water tank is provided with a number of penetrating water suction channels, and the engine flight experiment is carried out by simulating the cloud environment to detect the quality problems of the aircraft engine in the cloud environment, and by covering each small ice cube with a film Prevent the condensation of ice cubes during the conveying process, reduce variables, and use two sets of ice-making mechanisms and conveying mechanisms interleaved, and the return mechanism to filter the film and circulate ice water, so that the ice spray station can continuously spray ice water mixed with ice cubes , when atomized through the air nozzle, it is more in line with the realistic cloud environment.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to an aero-engine test system for simulating cloud environment. Background technique [0002] Before the aero-engine is put into the test, tests such as water swallowing test and ice swallowing test are required. The purpose is to simulate how much the aircraft engine will be affected when it encounters a cloud environment during flight, which is a necessary quality inspection. Among them, the ice swallowing test is similar to a collision test. When an airplane flies in the clouds, it will encounter hail. When the hail enters the engine, it will collide and rub against the high-speed rotating blades inside the engine, which may cause deformation and rupture of the blades and impellers inside the engine. affect engine performance. [0003] Because the ice swallowing experiment simulates natural extreme environments such as hailstones or clouds that suspend a large number of ice particle...

AI Technical Summary

Problems solved by technology

Therefore, it is more common for small ice cubes to coagulate with each other to form large ice cubes. This defect is difficult to solve under the current technical conditions.

[0006] At the same time, the real cloud environment is not instantaneous. The aircraft may need to stay in the cloud for a long time, or repeatedly enter and exit the cloud, while the conventional ice swallowing experiment is a one-time, short-lived experiment.

Therefore, it cannot simulate the scene of the aircraft flying in the cloud environment very well.
