摘要
飞行品质受横航向静稳定性导数影响显著。求解满足飞行品质要求的飞机横航向静稳定性导数的可行域,是选择垂尾面积和机翼上反角的基础。针对常规简化方法求解静稳定性导数可行域误差较大的问题,利用约束模式搜索方法求解静稳定性导数可行域。仿真计算说明,该方法相比常规简化方法精度更高,可以获得更为满意的可行域,有利于垂尾面积和机翼上反角的选择。
Flight quality is influenced obviously by lateral-directional static stability derivative.Solving the feasible region which satisfies flight quality requirements is used as a basis for choosing vertical fin and dihedral angle.To solve the problem of large calculation error of static stability derivative caused by traditional simplify method,using restraint pattern search method to solve lateral-directional static stability derivative.Simulation and calculation prove that this method is more accurate than traditional method,which can get more satisfactory feasible region and is benefit to the selection of vertical fin and dihedral angle.
