高燃点发射药作为无壳弹装药的可行性分析

STUDY ON HIGH IGNITION TEMPERATURE PROPELLANT FOR CASELESS AMMUNITION

通过大量的实验研究 ,对高燃点发射药的配方、能量、耐热性能、燃烧性能、烧蚀性能以及弹道性能进行了分析 ,提出了高燃点发射药作为无壳弹装药的可行性意见 .由惰性粘结剂、增塑剂和 HMX组成的高燃点发射药能量略高于单基发射药 ,而爆温低于单基发射药 ;通过 HMX固体颗粒尺寸和形状的控制 ,可使燃速压力指数控制在 1 .1左右 ;高燃点发射药的耐热性能通过在 350℃下抗自燃模拟时间和爆发温度点试验 ,其结果明显优于单基发射药 ,烧蚀小于单基发射药 ;通过无壳弹装药弹道试验 ,其点火正常、燃烧完全、膛内没有留膛现象 .

This paper demonstrated the high ignition temperature propellant for caseless ammunition. Its properties of force, heat resistance, combustion and erosion as well as ballistics are investigated. It exhibited better characteristics compared with single base propellant. The high ignition temperature propellant would be the best candidate for future caseless ammunition.
