Description

technical field [0001] The application belongs to the field of aero-engine design, and in particular relates to a flow path design method of a compressor bleed air module. Background technique [0002] The task of flow path design of the compressor bleed air module is to obtain an effective flow path of the compressor bleed air module for the given design indicators such as the position of the compressor bleed air structure and the amount of compressor bleed air under the constraints of the structural size. The quality of the flow path design of the bleed air module of the compressor directly affects the bleed air volume and pressure loss of the compressor, and even affects the performance of the compressor. The flow path design and evaluation of the bleed air module of the compressor are indispensable in the forward design process of the compressor link. [0003] The design process of the bleed air module is closely related to engineering, and the aerodynamics and structur...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the newly designed air-bleed module of the compressor is required to be similar in size, structure, and volume of air-bleed to the original air-bleed module. Due to its limitations, it brings corresponding technical risks, and problems are often discovered only in the experimental stage, which affects the industrial development cycle and leads to increased development costs

In addition, the traditional method is difficult to carry out the forward design of the flow path of the new form of bleed air module, and it is difficult to meet the design needs of high-performance compressors
