【Abstract】 In order to study the high-pressure combustion characteristics of combustible cartridge,the closed-loop explosive measuring-system was used to carry out the experiment of combustible cartridge material.The pressure-time curve of actual combustion process was obtained. On this basis,the theoretical model of high pressure combustion of combustible cartridge was established under the conditions of constant volume,and the numerical calculation was carried out. The combustion-performance parameters,burning-rate index and burning-rate coefficient of the combustible cartridge were obtained as well as the relation formula of burning-rate and pressure.The study results offer reference for improving the design of combustible cartridge for large-caliber module charge.更多还原
