本文叙述了再入体弹着点散布的两个重要因素:截锥体边界层的转捩和凹陷鼻尖上的气流分离。文中对这两种现象产生的横向力增量和这些力对散布的影响进行了分析计算,并给出了减小由此造成散布的再入体的设计方法。
This paper describes two important factors of reentry bomb blasting: the transition of frustum boundary layer and the separation of gas flow at the tip of the depression. In this paper, the increment of lateral force caused by these two phenomena and the influence of these forces on the dispersion are analyzed and calculated, and the design method for reducing the re-entry resulting from the dispersion is given.
