摘要
本文根据空气动力学的基本原理和有关实验分析,提出了一个底凹弹在超音速条件下侧壁开孔减小底阻的数学力学模型,本模型经初步计算结果与过去的实验结果基本相符,可作为探索底凹效应和底凹减阻工程计算的基础。
Based on the aerodynamic fundamentals and other expermental data, a mechanical model about a projectile with base cavity and side holes, which could reduce the base drag in supersonic speed, has been put forward in this paper. Since the comparision between calculations and experimental results is agreement well, the model could be taken as a basis to study the effect of base cavity and to make an engineering prediction.
