文章简要阐述了动力气垫地效翼船的空气-流体动力设计特点和难点，及“天鹅”号地效翼船的试验研究。由于采取一系列措施，使艇在静垫升性、两栖性、耐波性与气动力配平和运动稳定性等方面，在船模与实船上均取得令人满意的结果。

The features and difficulties of the craft design as well as the experimental investigation of DACWIG (Dynamic Air Cushion Wing-in-ground Effect Craft) are described in this paper. Both model and full scale craft tests demonstrated that the static hovering characteristics, powering performance, seakeeping quality and aerodynamics balance as well as transverse and longitudinal stability of the craft were satisfied, due to taking a series measures in the craft design. So DACWIG has prospective future in both civilian and military use.
