摘要:
基于某弹对延期件的延期时间要求的精度高,设计了一种高精度延期件。通过火帽选型、延期药剂的确定,以及优化设计延期体与连接体结构,在延期体壳体输出端实体部分挖出一个圆圈,将连接体大、小两端位置颠倒,并增大小端外径至36 mm,同时增大连接体内径为18 mm,从而增大了连接体空腔容积,使连接体与延期体组合后的消爆空间增大,延期药在燃烧过程中形成的预热空腔容积增大,为延期药燃烧提供较为一致的燃烧空间,使延期药燃烧产生的压力对燃速的影响更加均匀、稳定,增加延期药剂燃烧的稳定性,达到提高延期精度的要求。试验结果表明:该设计满足高精度延期时间(6.6±0.8)s的要求,可为今后的高精度延期件的优化设计提供参考。
Abstract:
A delay element with high precision was designed for a bullet to meet with its new requirement. The cap was selected and the delay composition was determined. Delay element and connecting structure were optimized. A circle was dug out at the entity parts of output delay body shell to reverse connection on both ends of the body size position. Increasing outer diameter of the small end to 36 mm and inner diameter of connection body to 18 mm increases the connector cavity volume, and thus enlarges the explosive space connecting with delayed body. Volume of preheating cavity formed in combustion process of delay composition increased providing a consistent combustion space. Thus, influence of combustion pressure on burning rate was more stable. It could meet the accuracy requirement of the delay element. Test results show that the delay time is in the range of (6.6±0.8) s. It could be used as reference for the optimization of delay element with high precision.
