采用CFD技术对鸭翼布局和常规布局飞机进行气动特性估算。利用计算机辅助软件对缩比飞机模型进行流体计算,通过对计算数据的处理,获得两种布局飞机在升力系数、阻力系数、升阻比、俯仰力矩等多个方面的典型气动特征参数,再对这些特征参数进行比对,最终得出两种布局飞机在气动方面的优缺点。 The CFD technology is used to estimate the aerodynamic characteristics of the duck wing and the conventional layout aircraft. By using computer-aided software to calculate the fluid of reduced-ratio airplane model, the typical aerodynamic characteristic parameters of two kinds of layout aircraft in terms of lift coefficient, drag coefficient, lift-drag ratio and pitching moment are obtained by processing the calculation data. These characteristic parameters are compared and finally the aerodynamic advantages and disadvantages of the two layout aircraft are obtained.
