Problems solved by technology

The gas flow supersonic wind tunnel system has many links, and the high-temperature and high-pressure test environment generated is extremely harsh. The coordination and timing control requirements of various components are extremely strict. A slight error may cause the equipment to burn out and affect the success of the test.
The traditional wind tunnel system lacks a unified management mechanism, and the functions of each component are relatively independent, which cannot achieve high-demand timing control and coordination

Description

technical field [0001] The invention relates to a wind tunnel operation control system based on a distributed architecture, which is used to control various parts of the gas flow thermal wind tunnel test system to realize thermal assessment of spacecraft heat-resistant structural parts, and belongs to the technical field of aerospace ground heat-insulation tests . Background technique [0002] The gas flow test is a key link in the ground assessment of the heat protection system. It has the characteristics of high energy density, high total temperature, and harsh thermal environment. It is an irreplaceable test method for thermal assessment of heat protection materials and structures. However, the assessment of large-scale heat-resistant structural test pieces needs to be carried out on the basis of the gas flow supersonic wind tunnel, which is different from the conventional room temperature aerodynamic test wind tunnel. The expansion and acceleration of the nozzle generat...
