中文摘要：

将水下滑翔器和水下自航行器两者功能集合于一身，提出了一种新概念混合驱动水下滑翔器．采用计算流体力学方法对混合驱动水下滑翔器滑翔状态下机翼对滑翔经济性和稳定性的影响进行了数值模拟研究，正交试验表明，其滑翔经济性受机翼弦长影响最为显著；滑翔器的稳定性受机翼的后掠角影响最为显著；对4个具体模型在0°～20°攻角的进一步的数值模拟表明，机翼的位置主要影响滑翔稳定性，对滑翔经济性影响较小．滑翔器在6°左右攻角航行时，具有最大的升阻比．研究为混合驱动水下滑翔器的设计提供了理论指导和参考．

英文摘要：

A novel hybrid-driven underwater glider （HUG） combining the advantages of underwater glider and autonomous underwater vehicle （AUV） has been proposed in this paper. Numerical simulation has been conducted to investigate the impact of the wings on the glide efficiency and stability of HUG in glide mode using computational fluid dynamics （CFD） .The orthogonal experiment shows that glide efficiency is most significantly influenced by the chord length while stability of the vehicle is most remarkably affected by the sweep angle. Further numerical calculations based on four specific models with the attack angle in the range of 0° --20° indicate that location of the wings mainly affects glide stability yet has little influence on glide efficiency. When the vehicle glides at about 6° attack angle it has the maximum ratio of lift to drag. The study provides theoretical guidance and reference for HUG design.
