Description
technical field [0001] The invention relates to the technical field of structural design and application of a flow test equipment control system, and in particular provides a control system for an aeroengine central cone flow test equipment and a method for using the same. Background technique [0002] The central cone flow tester is mainly used to test the flow distribution of 10 spray points on the central cone of the engine. In the past, the central cone flow detection equipment used the method of manually reading the indication of the measuring cup for detection, which caused large errors due to human factors and low efficiency. With PLC as the core controller, the computer collects the magnetic sensor data to eliminate human reading errors and improve efficiency. [0003] People urgently hope to obtain a control system of aeroengine central cone flow test equipment and its application method with excellent technical effect. Contents of the invention [0004] The obj...
