The invention provides a design method of a vertical take-off and landing aircraft and the vertical take-off and landing aircraft, and the design method comprises the steps: obtaining the vertical tail capacity of a vertical tail according to the number of tail fins and geometric parameters of the tail fins; according to the number of the tail fins, the geometrical parameters of the tail fins and the vertical fin capacity, a three-dimensional model of the tail fin layout scheme is constructed; hydrodynamic pretreatment is carried out on the three-dimensional model, and a change curve of a yaw moment coefficient of the three-dimensional model along with a sideslip angle under the tail fin layout scheme is obtained; according to the slope of the change curve, judging whether the geometric parameters conform to a design value; if the design value is met, tail fin layout design is completed; if not, readjusting the geometrical parameters of the tail fin and the corresponding three-dimensional model until the slope of the change curve meets the design value; according to the vertical take-off and landing aircraft designed through the design method, the technical problem that under the condition that the empennage is swept forward, the dynamic stability modal flight quality of the aircraft in the transverse direction is low can be solved.
本发明提供一种垂直起降飞行器的设计方法及垂直起降飞行器,该设计方法包括:根据尾鳍数量和尾鳍的几何参数,获取垂直尾翼的垂尾容量;根据尾鳍数量、尾鳍的几何参数及垂尾容量,构建尾鳍布局方案的三维模型;将三维模型进行流体动力学前处理,并获取尾鳍布局方案下三维模型的偏航力矩系数随侧滑角的变化曲线;根据变化曲线的斜率,判断几何参数是否符合设计值;若符合设计值,则完成尾鳍布局设计;若不符合,则重新调整尾鳍的几何参数及对应的三维模型,直至变化曲线的斜率满足设计值;通过该设计方法设计的垂直起降飞行器,可以改善在尾翼前掠的情况下,飞行器横航向的动稳定性模态飞行品质较低的技术问题。
