| 摘要: |
| 为提高翼身融合水下滑翔机的操纵性及稳定性，将后缘舵融入其外形设计，并进行了CFD数值仿真，给出了其升力、阻力、升阻比等水动力参数随攻角、舵角的变化规律及相关云图。相比于传统水下滑翔机，翼身融合水下滑翔机不仅装载能力高，其最大升阻比更是前者的3倍，具有更高的能源利用效率。同时，通过增设后缘舵，提升了翼身融合水下滑翔机的机动能力，且相较于可变翼水下滑翔机，相同大舵角下升阻比提升30%以上。最后通过对数值结果和云图的分析，阐述了翼身融合水下滑翔机与传统鱼雷及AUV，舵和本体间相互影响程度上的区别。 |

| Abstract: |
| In order to improve the maneuverability and stability of the Blended Wing Body (BWB) underwater glider, the trailing edge rudder is integrated into its shape design in this paper. Through the numerical simulation of CFD, the variation laws of the hydraulic parameters such as lift, drag, lift-to-drag ratio with the angle of attack and rudder angle are given. Compared with the traditional underwater glider, the BWB underwater glider not only has high loading capacity, but also has a maximum lift-to-drag ratio three times that of the former, resulting in higher energy efficiency. At the same time, by adding trailing edge rudders, the maneuverability of the BWB underwater glider is improved, and the lift-to-drag ratio under the same large rudder angle is increased by more than 30% compared with the variable-wing underwater glider. Finally, through the analysis of the numerical results and the cloud image, the difference interaction extent between the rudder and the body of the BWB underwater glider and the traditional torpedo or AUV is illustrated. |
