摘　　要：该文将经典的普朗特升力理论推广至近海面掠飞的地效翼升力问题,包括升力线和升力面理论。以往的研究通常将海面简化为固壁进行研究,该文着重研究自由表面效应对地效翼升力的影响,考虑掠海地效翼和自由表面相互作用。仿照无限空间的普朗特理论,建立了考虑自由表面条件的升力线和升力面理论;考察了地效翼的升力和阻力、机翼升斜角、机翼端板和串列翼等因素的影响。In present article, the classical Prandtl lifting theory is generalized to wing-in-ground effect （WIG） in proximity to the sea surface, including lifting line theory and lifting surface theory. In the previous research, the sea surface is simplified as a planar ground. For this reason, the present study is focused on WIG considering the interaction between the foil and the sea surface. Similar to the Prandtl lifting theory in free space, the lifting line theory and lifting surface theory in the presence of a free surface are extended to investigate the influences of the dihedral angle, winglets and tandem arrangement on the lift and drag forces. The present study can be used as a technical support in the design process.
