摘要该引信配用于大多数型航空炸弹，具有隔爆机构、冗余保险、延期解除保险、触发发火的功能。为了给通用航空炸弹引信设计提供指导，分析了国外的典型航空炸弹引信，并进行了归纳和总结：为了保证其结构的正确性，通过理论计算对引信外壳、螺纹、本体等薄弱部位和弹簧进行了强度校核；为了保证勤务处理安全，通过理论计算对弹进行了1.5m跌落钢板校核，结果表明能满足安全落高；为了保证解除保险可靠性，通过理论对钢条保险机构、离心子保险机构进行了性能分析，结果表明其都能可靠得解除保险；为了保证设计尺寸的正确性和合理可靠装配，对引信各零部件的尺寸进行了尺寸链计算。引信的安全性符合GJB373A-1997《引信安全性设计准则》和GJB537A-1998《引信环境与性能试验方法》的相关要求。69430

Title              Design of General Aviation  Bomb Triggered Fuze                     

Abstract

The fuze is applicable to most kinds of aviation bomb, with flame-proof institution, redundant safety device, delay arming device, and the function of triggering fire. For the purpose of providing guidance for general aviation bomb fuze design, this article analysed the typical aviation bomb fuze of abroad and concluded the summaries. In order to guarantee the correctness of the structure, doing intension check to the weak part: fuze case, thread, ontology and spring by theoretical calculation. In order to guarantee the service processing safety, doing 1.5m dropping steel plate by theoretical calculation and the result shows it meets the safe falling height. In order to guarantee the arming reliability, doing performance analysis to Lanyard insurance and rotor safety by theoretical calculation, the result shows both can remove safety reliably. In order to guarantee the correctness of size design and reasonable reliable assembly, doing size-chain calculation to fuze parts' size. Fuze Specifications and functions can be achieved.
