Research on Forecast Ammunition Ballistic Property with Powder Property

摘要

Nowadays, the shoot way is usually adopted when examining ballistic property of ammunition. The special test rang and installation been demanded when using this way. For enhancing the utilization of the chemical checker, the research on forecast ammunition ballistic property with powder property is progressed.Author deems that the change of ballistic property of ammunition depends on the change of powder property, if not dud or prolonging firing during the shooting. Take the ball cartridge for example f the relation between ballistic property and powder property is formulated:(ΔV_0)/(V_0)((ΔP_m)/(P_m))=f(DPA,ETV,ITV,)Where DPA is diphenylamine content (%), ETV is external volatile content (%), ITV is internal volatile content (%).
