摘　　要：地效翼船的起降过程是水动力和气动力相互耦合作用的过程。文章对地效翼船起降过程的特点进行分析,提出了适用此种情况的运动方程,将起降过程的空间运动分解为孤立的纵向运动与横侧运动。使用小扰动线性化分析方法分别研究航向稳定性和纵向稳定性,并且考虑了风、浪对它们的影响。　In the taking off and landing process of WIG,the motion is hydrodynamic and aerodynamics coupling one. In this paper, the space motion equation of WIG for the analyses motion characteristic in taking off and landing process is introduced.The motion have decoupled into longitudinal one and lateral one. The course stability and longitudinal stability are studied respectively by small perturbation method. The effects of wind and wave are considered also.
