Abstract

Conventional ammunition easily deviates from the intended target. Its hit probability is reduced by such disturbance factors as fabrication errors, initial muzzle disturbance, initial velocity probable error, and stochastic wind effect. The effect of the above interference factors can be reduced by improving the shooting dispersion, ammunition, and gun or rocket engine structure. However, such improvements may fail to meet the operational requirements for modern warfare. Ballistic correction technique is a proposed trajectory control technique for precision strike with effective damage. Taking a 57mm calibre projectile as research object, trajectory correction projectile with different aerodynamic layouts were designed. The aerodynamic characteristic, static stability, exterior ballistic characteristic and firing density of each projectile has been studied through research method of theoretical analysis and numerical calculation. These findings are considered instrumental in the trajectory correction technology research and engineering application.
弹道修正弹的弹道和气动特性仿真
常规弹药很容易偏离预定目标。考虑了制造误差、初始炮口扰动、初始速度概率误差和随机风效应等干扰因素,降低了其命中概率。上述干扰因素的影响可以通过改善射击弥散、弹药和火炮或火箭发动机结构来减小。然而,这种改进可能无法满足现代战争的作战要求。弹道修正技术是一种针对有效杀伤精确打击而提出的弹道控制技术。以某57mm口径弹丸为研究对象,设计了不同气动布局的弹道修正弹。采用理论分析和数值计算相结合的研究方法,对各弹的气动特性、静稳定性、外弹道特性和发射密度进行了研究。这些发现对弹道修正技术的研究和工程应用具有重要意义。
