变燃速发射药的原理与实现方法

根据身管武器内弹道特点，提出了变燃速发射药的概念，论述了基本原理和实现该原理的技术方法。采用内层为高燃速发射药，外层为低燃速发射药。达到变燃速的目的。实验证明，两层结构的变燃速发射药具有所希望的能量释放规律，表现出很好的渐增性燃烧。变燃速发射同时还具有高能量、普遍适应性、高安全性等特点。

Principle and Realizable Approach of Variable Burning Rate Propellant

According to the interior ballistic performance of guns, a concept of variable-burning rate propellant was put forward, the fundamental principle of this propellant was discussed and the technologic way to realize the principle was explained.In order to realize the variable-burning rate ,the propellant has two layers ,inner layer's burning rate is higher than the outer layer's. The results show that two-layered variable-burning rate propellant has wishful discharge rule and good properties of progressive combustion.The propellant has the advantages of high energy,universal applicability and high security.
