The compressor wall surface treatment device comprises an annular compressor box, an annular porous composite metal plate and an annular rectification plate, wherein the annular porous composite metal plate is formed by piling multiple porous composite metal plate layers, the annular compressor box is provided with an annular back cavity, the annular porous composite metal plate is disposed in the annular back cavity, and the annular rectification plate is buried in the annular porous composite metal plate.

Description

technical field [0001] The invention belongs to the technical field of turbines, and in particular relates to a compressor wall surface treatment device with functions of expanding stability and eliminating noise, which can reduce the internal noise of the compressor while widening the stable operation range of the axial flow compressor. Background technique [0002] As one of the key components of the air-breathing propulsion system, the compressor is widely used in the compression systems of aero-engines, air-breathing cruise missiles, and energy and chemical industries. However, researchers are faced with various unsteady flow stability issues in the design work of modern high-load axial flow compressors. In recent years, with the continuous increase of the workload, it is more likely to cause the problem of insufficient stable working margin of the compressor within the working range, so the compressor stability expansion technology is very important. At the same time, ...
