Numerical Simulation of Interior Ballistics of Surface-to-Air Missile's Vertical Ejection Device Based on MATLAB

In order to better simulate the vertical ejection process of a certain type of surface-to-air missile, this article establishes a certain type of surface-to-air missile ejection device high-pressure indoor ballistic equation, low-pressure indoor ballistic equation, missile motion equation and pressure relief hole exhaust equation, and use MATLAB software to program. The pressure curves of the high and low pressure chambers with time, the gunpowder combustion curve and the missile movement curve are obtained. Comparing the data simulation results with the research results of other scholars, the results show that the algorithm can better reflect the change trend of each key parameter in the missile ejection process, and the obtained data can be used as the experimental basis for missile launch dynamics simulation.
