Modeling simulation method for temporary impulse type wind tunnel system

The invention discloses a modeling simulation method for a temporary impulse type wind tunnel system. The modeling simulation method is mainly used for carrying out simulation analysis on basic components and parameters of a temporary impulse type wind tunnel. The main hypothesis of the modeling simulation method is a one-dimensional uniform flow hypothesis, and under the hypothesis, modeling of the whole wind tunnel system is mainly divided into three parts: 1) modeling of an ejector and a spray pipe; 2) airflow modeling of other parts, and analysis in a 'pressure cavity-valve-pressure cavity' triple mode; and 3) valve modeling and control simulation. The main hypothesis and the triple analysis mode of the method can be used for other types of wind tunnels, but cannot be used for hypersonic speed combustion wind tunnels. MATLAB/Simulink software is adopted for simulation, and degradation and fault simulation of the wind tunnel system can be achieved by adjusting relevant parameters of the model. 本发明公开了一种面向暂冲
