摘　　要：介绍了变燃速发射药的原理和实现方法,内层采用高燃速发射药,外层为低燃速发射药,从而达到变燃速的目的;分析了双层结构变燃速发射药的密闭爆发器燃烧性能及30mm火炮内弹道试验结果。与高分子包覆单基发射药相比,双层结构变燃速发射药具有较好的燃烧渐增特性和明显的低温度系数效果。The principle and realizable approach of variable-burning rate propellant, the burning rate of inner layer is higher than that of the outer layer are introduced. The combustion character of two layered variable-burning rate propellant in closed bomb test is analyzed and the interior ballistic performance on 30mm gun is construced. Contrast with single base gun propellant with polymer coating layer, the two-layered variable-burning rate propellant has good properties of progressive combustion and low temperature coefficient.
