摘要
研究了发射药的燃烧残渣特性及残渣对内、外弹道的影响。提出将枪药燃烧残渣分为附着性残渣、漂浮性残渣和沉降性残渣,有害燃烧残渣主要是漂浮性残渣和附着性残渣。为探索充氮氧弹法用于测试附着性燃烧残渣方法的可行性,进行了8种发射药样品的烟室法、充氮氧弹法和TG残渣测试。结果表明,充氮氧弹法测试可区分不同枪用发射药燃烧附着性残渣的大小,漂浮性残渣用烟室法测定;不同发射药的残渣生成量差异很大,附着性残渣较大时,其漂浮性残渣也较大。
Characteristics of gun propellant combustion remains and their negative effects on interior and exterior ballistics have been studied, suggesting that gun propellant combustion remains can be sorted into three categories, one adhesive remains, one floating remains and another sinkable remains, and the front two remains are mostly harmful. Nitrogen-bomb test, a new method, is used to determine the amount of adhesive remains and evaluate the feasibility of the method. Fume-box tests, nitrogen-bomb tests and TG tests of some different gun propellants are conducted and results obtained show that nitrogen-bomb test can clearly show the difference of adhesive remains of different gun propellants. Floating remains are measured by Fume-box test. Tests reveal that different gun propellant has dramatically different adhesive remains, more adhesive remains usually accompany with more floating remains.
