摘要
研究分析了细长旋成体弹身类型气动外形的大攻角范围气动特性。描述了大攻角范围的单独弹身流场特性;分析了运用横流比拟法进行大攻角气动特性工程估算的方法;并以 THAAD 拦截弹为例,计算、分析并总结了细长旋成弹体的大攻角非线性气动特性,提出了导弹总体设计中需要注意的大攻角非对称侧力和静不稳定性的问题。
The static aerodynamic characteristics for slender bodies at large angle of attack was analyzed.First,the fluid around single body was described.Then the method of prediction of aerodynamic characteristics at large angle of attack by using of the cross-flow theory was introduced.Finally,the nonlinear aerodynamic characteristics at large angle of attack for THAAD interceptor were calculated and analyzed.Additionally,two aerodynamics problems to which we should pay attention during missile system design were ...
