为获得带升力风扇飞翼布局飞机因开口对机翼气动特性的影响规律,对平飞状态下开口机翼的气动特性进行三维气动仿真,分析升力系数、阻力系数和力矩系数随来流速度和迎角变化的特性。结果表明:随着来流速度增大,阻力和力矩呈上升趋势;来流速度一定时,随着迎角加大,升力系数增大,阻力系数先减小后增大;随着迎角增大,力矩系数先减小后增大再减小,且一直产生低头力矩。
In order to obtain the aerodynamic characteristics of airfoil with lift fan flying wing due to the opening, a three-dimensional aerodynamic simulation of the aerodynamic characteristics of the open wing under leveled flight was carried out. The lift coefficient, drag coefficient and moment coefficient were analyzed with the flow rate and Angle of attack characteristics. The results show that the resistance and moment increase with the increase of the incoming velocity. When the incoming velocity is constant, with the increase of the angle of attack, the lift coefficient increases and the drag coefficient first decreases and then increases. Large, moment coefficient decreases first and then increases and then decreases, and has been producing bow torque.
