根据文献[3]、[4]提供的细长旋成体大迎角侧向载荷工程估算方法,本文综合了它的内容,进行了推导和分析,编制了计算软件,提供了算例和实验验证。本文指出,侧向载荷的估算结果,在量级和变化趋势上符合实验数据,有时甚至可以达到相当接近的程度。因而读方法可以用于工程设计中。 According to [3], [4], a method of lateral load estimation of slender body at high angle of attack is presented. The content of this article is summarized, the deduction and analysis are made, the calculation software is provided, examples and experiments are provided . This paper points out that the estimation of lateral loads is consistent with the experimental data in terms of magnitude and trend of change and can sometimes be reasonably close. The reading method can therefore be used in engineering design.
