鉴于栅格翼相对于传统平板翼所体现的优越性，有必要研究其气动特性。栅格壁剖面形状作为一个重要的几何特征，采用数值模拟的方法，分别对不同的剖面形状进行气动分析。结果显示：剖面形状为菱形、四角形、六角形的栅格翼与矩形剖面的栅格翼相比能够很大程度的减小阻力，一定程度上增加升力，并且提高升阻比。流线型剖面的栅格翼中，菱形和四角形的栅格翼存在较好的气动性能。

superiority reflected in grid fins compared traditional flat wing, it is necessary to study their aerodynamic characteristics. The cross-section shape for grid important geometric parameter, numerical simulation method aerodynamic analysis of different cross-sectional shape. The results showrid fins with cross-sections as diamond, square, hexagonal can greatly reduce resistance compared with the rectan-gle bluff cross-section ones. At the same time, they also increase the lift and lift-drag ratio to some extent. Among the grid fins streamlined cross-section, dynamic performance.
