Description

technical field [0001] The invention belongs to the technical field of air flow of aviation gas turbines, and in particular relates to a flow table system for debugging the air flow of gas turbines. Background technique [0002] In the aeroengine system, the core machine is the main core unit, which consists of three parts: compressor, combustion chamber and turbine. The air compressed by the compressor enters the combustor and the turbine and is divided into multiple flow paths, including air for cooling and air for combustion or work. The air volume used by each part is distributed by some designed holes, channels, etc. The accuracy of air flow distribution affects the efficiency and cooling safety of the gas turbine. During the design and test of the combustor and turbine, some important components such as the main swirler, turbine guide vane, and flame tube need to be adjusted for air flow to confirm whether the air flow through the manufactured holes or channels meets ...
