弹头尾翼不同布局的气动特性分析

为了分析不同尾翼对作用在弹头上的空气动力的差异,分析弹头的机动能力,利用理论分析、实验数据和仿真计算,进行了弹头尾翼十字型和叉型布局的气动特性研究。通过建立弹头气动参数模型、分析空气动力试验数据,及对静稳定裕度、舵面控制效率及气动耦合的讨论和仿真,得到了二者气动差异的相关结论。

Analysis of Aerodynamic Characteristics of Difference Configuration Vane on Tactical Missile Warhead

In order to analyze the dynamical difference of dissimilarity's air in the warhead due to different tail wing layout form,this paper analyzes the mobile ability of warhead,by use of theories analysis,experiment data and imitative calculation.The results of difference configuration vane's aerodynamic characteristics are discussed.The results of analysis and simulation show that the static stability margin,control surface efficiency and coupling interactions of pitch,roll and yaw are different.And it gets both related conclusion of the dynamical difference.
