X型尾翼布局对无人机静稳定性的影响

Study on the Impact of X-Tail on Static Stability for an UAV

针对某型无人机所采用的X型尾翼布局,利用求解三维Euler方程的数值计算方法,得到了不同尾翼夹角和安装角状态下的全机纵向及横航向力矩值,并以此分析和研究了X型尾翼的夹角和安装角对无人机纵向及横航向静稳定性的影响。在此基础上,根据飞机的静稳定性要求,确定了该型无人机的尾翼夹角及安装角。

In this paper, aimed at the X-tail of an UAV, the aerodynamic momental performance of an UAV on different states of the X-tail is calculated by using the method of solving three dimensions Euler equations. The influence of X-tail＇ s intersectant angle and incidence on UAV＇ s static stability is analyzed and studied. Based on the request of UAV＇ s static stability, the intersectant angle and incidence of the X-tail is determined.
