【摘要】 为提高轻武器发射药燃烧渐增性和内弹道性能，采用四孔多孔发射药药型，开展了四孔发射药的静态和动态燃烧性能研究。采用密闭爆发器进行静态燃烧测试，在5.8mm弹道枪上进行了动态燃烧性能测试。结果表明，在未钝感的情况下，四孔发射药的燃烧渐增性优于球扁药和单孔发射药。对比四孔发射药，球扁发射药和单孔发射药的弹丸初速分别减小了17m/s和40m/s,烟雾透过率分别降低了18%和15%。静态和动态燃烧性能测试结果表明，四孔发射药比球扁发射药和单孔发射药有更好的燃烧渐增性和内弹道性能。更多还原

【Abstract】 To increase the burning progressivity and internal ballistic performance of small arms gun propellants,multi-hole gun propellants with 4-perforations are deployed,and the static&dynamic combustion performance are investigated.A closedbomb is used to test the static combustion performance,and 5.8mm testing guns are used to test the dynamic combustion performance.The results show that,without deterring,the progressivity of 4-perforated gun propellant is better than that of oblate ball and 1-perforated gun propellants.The muzzle velocity of oblate ball and 1-perforated gun propellants are 17m/s and40m/s lower than that of 4-perforated gun propellant,respectively.The light transmittance of oblate ball and 1-perforated gun propellants are 18%and 15%lower than that of 4-perforated gun propellant,respectively.The static and dynamic results show that 4-perforated gun propellants have better progressivity and internal ballistic performance than those of oblate ball and1-perforated gun propellants.更多还原
