四孔发射药的静态和动态燃烧性能研究
Static and Dynamic Combustion Performance of 4-Perforated Gun Propellants
摘要
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 closed-bomb is used to test the static combustion performance ,and 5 .8 mm testing guns are used to test the dynamic combustion per-formance .The results show that ,without deterring ,the progressivity of 4-perforated gun propellant is better than that of ob-late ball and 1-perforated gun propellants .The muzzle velocity of oblate ball and 1-perforated gun propellants are 17m/s and 40 m/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 and 1-perforated gun propellants .关键词
