Charge design methods affect the ballistic performance of the engine. In order to improve the charge utilization rate, UG NX and MATLAB software were used for modeling and programming of the calculation, and the function relationship diagram of the combustion surface, the residual drug rate and the design parameters during the combustion process of the drug column was obtained, and finally the example analysis was carried out. The results showed that when
