Abstract

The invention discloses a production method of a diffuser used in aerodynamic experiments and belongs to the technical field of design and production of high temperature and hypersonic velocity aerodynamic experiment equipment. The production method can effectively improve product quality and has fast assembly speed. The production method includes: processing flange parts with inner cylinder positioning steps and outer cylinder positioning steps on flange blanks, drilling positioning holes in outer cylinder blanks, making inner cylinder parts and outer cylinder parts through rolling, and assembling the inner cylinder parts and the outer cylinder parts on the basis of the inner cylinder positioning steps and the outer cylinder positioning steps. In addition, the thickness of cavities between the inner cylinder parts and the outer cylinder parts is controlled through a positioning short pipe so the purposes of improving product quality and assembling speed can be achieved.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a manufacturing method of a diffuser for aerodynamic testing, and belongs to the technical field of design and manufacturing of high-temperature, hypersonic aerodynamic testing equipment. Background technique [0002] The diffusion and depressurization section is an indispensable special device in the complete set of high-temperature and hypersonic aerodynamic tests. It is located behind the test section and mainly performs the role of diffusion and decompression and deceleration of the high-pressure and high-speed airflow after the test. Its structure is a double-layer pressure-bearing structure, and the interlayer cavity is a channel for circulating cooling water. The purpose is to take away the heat transmitted from the inner shell and ensure that the temperature rise of the inner shell is within a certain range, thereby ensuring the performance of the diffuser section. Safe and relia...
