摘要:
针对环切杆状发射药装药，设计了两种点传火方案进行试验验证:方案1#是中心传火管；方案2#是在中心传火管上端增加一个点火药包，以便加强弹丸底部装药的点火。通过100 mm火炮弹道试验负压差的分析，两种点传火方案均能满足点传火技术要求，方案2#负压差较方案1#负压差小，射击安全性提高。对点火延迟时间的分析发现，点火延迟时间越短，起始燃气生成速率越高，越易生成较大的压力波。
Abstract:
Two ignition methods were designed for curve-cut stick gun propellant charge. The first one was central core igniter, and the second was addition of an igniter bag on the top of the central core igniter to enhance the ignition of bottom propellant charge. Firing test results by 100 mm ballistic gun show that both of the two methods could meet the requirement of ignition. Negative pressure difference of the second ignition method is smaller than that of the first ignition method, and the security of fire is improved. It has been observed that the shorter the ignition delay time of propelling charge is, the larger the gas production rate of propelling charge will be and easier formation of a serious pressure wave in chamber.
