摘　　要：针对地效飞行器纵向静稳定性这一重要技术问题,应用数值模拟的方法对鸭式布局地效飞行器的纵向静稳定性进行了研究。首先对传统布局与鸭式布局纵向静稳定性的特点进行了对比分析;然后,通过改变前置鸭翼展弦比分析其对纵向静稳定性的影响。研究结果对地效飞行器的气动布局设计和研究有一定的指导和参考价值。Longitudinal static stability is one of the major technical difficulties for a wing-in-ground effect （WIG） craft. The characteristics of longitudinal static stability for a canard type WIG craft were studied by numerical simulations. Firstly, comparisons were made between conventional airplane type and canard type on longitudinal static stability in ground effect. Then, effect of the canard wing was concerned with changing the aspect ratio. The present study provides theoretical basis for the design and research on configurations of WIG crafts.
