摘　　要：采用有限体积法求解定常可压缩流的质量加权平均N-S方程和Standard-Allmaras湍流模型,对超巨型地效飞行器全机水面巡航状态进行气动特性计算分析。通过研究端板厚度、主翼安装角、巡航高度、飞行迎角等因素对气动特性的影响为超巨型地效飞行器的气动布局设计提供依据。在综合考虑升阻比和海况的影响下,确定超巨型地效飞行器的最佳巡航高度为5~30 m,最佳巡航迎角为2°左右。It uses the finite volume method to solve the Naiver-Stokes equation of steady compressible flow and numerically investigating the wing-in-ground(WIG)craft under cruise.It takes the thickness of endplate,the incidence angle of main wing,the flight altitude and the angle of attack as variables to calculate and analyze the aerodynamic characteristics of the whole super-giant WIG aircraft and to provide the information for the whole layout design.Considering the influence of lift-to-drag ratio and sea condition,the best cruise altitude is around 5~30 meters and the optimal cruise angle of attack is about 2°.
