小口径尾翼弹与尾裙弹的弹道特性分析

The Analysis of Ballistic Characteristics to Flare and Fin Stable Penetrators of Small Calibre

作为新一代的高超音速小口径杆式脱壳穿甲弹,其弹芯结构目前主要为尾翼式和尾裙式两种形式.显然不同的结构形式在飞行弹道上的弹道特性是不一样的,但在理论上弄清这种尾部结构上的差异(尾翼与尾裙)究竟对弹芯在飞行弹道上的空气动力特性、飞行稳定性特性、速度降特性等有多大影响,以及将二者在结构简易性、成本等多方面的综合因素对比分析,对帮助最终确定采用哪种尾部结构方案,是有一定参考意义的.该文主要根据查阅到的一些研究文献,结合理论分析与计算,对两弹的外弹道特性作了综合对比分析.

The fin-stable and flare stable structure,as main styles of long rod ar-mour-pierce discard penetrators,have different ballistic characteristics.The differ-ence includes aerodynamic performance,flight stability,reduction of velocity,sim-plicity and economy of two structural patterns.It is helpful to determine which pat-tern the designer should choose if above differences have been known.The paper,based on the theoretical analyses and calculations,makes a comparison of exteriorballistics for two kinds of penetrators two kinds of penetrators.
