Modeling Analysis of Supersonic Free Jet Test System Based on Matlab/Simulink

In order to simulate the dynamic change process of the key index cabin pressure, the key physical process of supersonic free jet test system is modeled based on Matlab/Simulink, and the simulation results are compared with the test results. The curve variation law of the simulated cabin pressure of...

description	In order to simulate the dynamic change process of the key index cabin pressure, the key physical process of supersonic free jet test system is modeled based on Matlab/Simulink, and the simulation results are compared with the test results. The curve variation law of the simulated cabin pressure of the model is consistent with that of the test cabin pressure. The error between the simulated cabin pressure and the test cabin pressure in the stable section of the test state is within 1 kPa, and the simulated static pressure at the nozzle outlet and the test static pressure are also less than 1 kPa. At the same time, it also has the ability to simulate the start-up hysteresis phenomenon and the main line relationship between the cabin pressure after startup and the total pressure at the nozzle inlet. The comparative analysis results show that the Simulink modeling method can effectively simulate the dynamic change of cabin pressure of supersonic free jet test system.
