摘要：前掠翼与串置翼各自具有独特的气动和结构优势，螺旋桨滑流对其的气动影响作用需要分析研究。基于一种螺旋桨动力串置前掠翼布局模型，螺旋桨直径0.232 m，应用UG和ICEM CFD软件，划分大小流动区域并考虑壁面粘性附面层特点，构建三维模型的结构/非结构混合网格模型。应用FLUENT软件，对无螺旋桨时模型的低速纵向气动力进行数值模拟，在飞行马赫数0.3和5°攻角时模型升阻比获得最大为7。在最大升阻比状态下，考虑前置螺旋桨工作的影响，数值模拟螺旋桨滑流作用下模型的低速气动力特性，螺旋桨转速24638 r/min，发现旋转滑流对前后翼都有降低绕流逆压梯度作用，前翼和后翼压差载荷均有所增大，模型总体升力相应提高。

Abstract：The forward swept wing and the tandem wing have their unique aerodynamic and structural advantages, and the aerodynamic influence of the propeller slipstream needs to be analyzed. On the basis of a tandem forward swept wing model powered by propeller with a diameter of 0.232m, UG and ICEM CFD software are used to divide the flow area and discover the characteristics of the adhesive wall boundary layer to construct a 3D model and structure/unstructured hybrid mesh model. And then, the low-speed longitudinal aerodynamics of the model without propeller is numerically simulated though FLUENT software,. The maximal lift-to-drag ratio of the model is obtained at the flight of Mach 0.3 and angle of attack 5°. Under the condition of maximum lift-to-drag ratio, the low-speed aerodynamic characteristics of the model influenced by propeller slip flow are numerically simulated while the front propeller is working, and the rotation speed of the propeller is 24,638 r/min. It is found that the slipstream has the effect of reducing counter-pressure gradient of the flow around the front and the rear wings; the overall lift of the model increases with the increase of the differential pressure load on the front and the rear wings.
