| 摘 要： | 采用基于S-A一方程湍流模型的雷诺平均法求解N-S方程,研究了盒式机翼布局前后翼几何参数对气动特性的影响规律,为盒式布局飞机气动设计提供参考。结果显示:随着前后翼垂直距离的增大,盒翼升力和升阻比均增大;增大前后翼的纵向距离,盒翼升力增加;盒翼气动性能对两翼纵向距离的敏感程度不及对两翼的垂直距离。

| Abstract: | To study the effects of geometric parameters on the aerodynamic characteristics of a box-wing body,The Reynolds-Averaged Navier-Stokes equations based on the S-A turbulence model are solved.And then,the law of design parameters is discussed.The computational results show that the lift and lift drag ratio of the box-wing body gets larger as the vertical distance between the rear wing and front wing increasing.The lift becomes larger as the longitudinal distance of the two wings gets longer.The aerodynamic characteristics of the box-wing configuration are more sensitive to the vertical distance than the longitudinal distance. |
