地面效应是机翼贴近表面运动时出现的一种使机翼气动特性发生显著变化的空气动力学现象,即升力增大、诱导阻力减小。地效飞行器正是利用这种效应实现掠海高速飞行的运载工具,具有高升阻比、高速安全等特点,已受到许多国家的重视。近年来,国内外研究者应用试验、理论和数值模拟方法对三维地效飞行器近水面气动特性进行了比较深入的研究。恽良等对“天鹅号”地效翼船进行了试验研究;洪亮等用标准k-epsilon湍流模型计算了XTW4地效翼船巡 The ground effect is an aerodynamic phenomenon that occurs when the wing approaches the surface and significantly changes the aerodynamic characteristics of the wing. That is, the lift force increases and the induced resistance decreases. Effectiveness of spacecraft is the use of this effect to achieve high-speed fly-by-sea flying vehicles, with high lift resistance, high-speed security and other characteristics, has been valued by many countries. In recent years, researchers at home and abroad have made a comparatively thorough research on the aerodynamic characteristics of the three-dimensional ground-effect vehicle near surface using the experimental, theoretical and numerical methods.恽 Liang and other “Swan” to the effectiveness of the wing of the pilot research; Hong Liang and other standard k-epsilon turbulence model calculated XTW4 to the effectiveness of the wing patrol
