Background
The air inlet device is used for sucking air and has the functions of stabilizing flow, stabilizing pressure, removing water, removing salt and silencing. Compressor (compressor): gas turbine engines utilize blades that rotate at high speeds to do work on the air to increase the air pressure. The front end part of the blade of the compressor impeller is bent and called as a guide wheel, and the guide wheel plays a role of guiding gas into the working impeller without impact so as to reduce the impact loss of gas flow. The compressor wheel of a small supercharger typically integrates a stator wheel with a working wheel. The outlet of the impeller of the compressor is provided with a diffuser, so that the kinetic energy obtained by the gas in the impeller is converted into pressure as much as possible. Diffusers are classified into vane type and slit type. The shell of the compressor is provided with an air flow inlet and an air flow outlet. The inlet is generally arranged axially, and the flow passage is slightly reduced in diameter so as to reduce air intake resistance. The outlet is typically designed as a volute with a circumferentially diverging flow path, where the high velocity gas stream continues to diffuse, increasing the overall efficiency of the supercharger. The compressor is driven by a turbine, and the main performance parameters of the compressor are as follows: rotational speed, flow, air flow, pressure ratio, efficiency, etc. However, most air intake devices operate with relatively high noise.
