摘　　要：地效翼布局和翼型选择在很大程度上决定地效翼艇的性能和效能,对地效翼艇的设计至关重要。文章根据地效翼布局和翼型的特点,采用基于升力面理论的镜像法计算三维组合地效翼和简单地效翼在地效区和超出地效区的纵向气动特性参数,分析布局型式和外形参数对地效翼气动特性的影响。得到的组合翼在地效区内外比简单地效翼具有更好的升阻特性的结果,表明组合翼布局适合于掠海高飞型地效翼艇,研究也为地效翼布局型式、外形参数选择以及吹风模型制作提供了依据。The layout and airfoil play an important role in WIG craft design for their great effect on the performance and effectiveness. Taking into account of the characteristics of the airfoils and configuration layouts of the wings of WIG craft, the longitudinal aerodynamic characteristics in and out of ground effect of combined and simple wings were calculated based on the lifting-surface solution and the ground effect was simulated with a mirror image wing, and the effect of the layout and geometric parameters on the longitudinal aerodynamic characteristics of wings of WIG craft was analyzed. The results show that the lift and drag characteristics of combined wings are better than simple wings both in and out of ground effect, and that the combined wings are fit for sea-skimming and high-flying WIG craft. The study also provides the basis for the selection of layout and geometric parameters of wings and the wind tunnel models for WIG craft.
