翼身融合式水下滑翔机作为一种新型的水下滑翔机，具有良好的水动力性能，针对其开展的研究也越来越广泛。为论证等容积下翼身融合式水下滑翔机对比传统水下滑翔机具有水动力性能上的优势，选取2种外形的水下滑翔机进行三维建模，控制其内部容积相等。采用CFD计算方法，在不同速度、不同攻角下对2种模型进行仿真模拟并对比分析两者的水动力性能。结果表明，容积相等条件下，翼身融合式水下滑翔机的水动力性能对比传统水下滑翔机，最大升阻比提升了2.3倍。
As a new type of underwater glider, the blended-wing-body underwater glider has excellent hydrodynamic performance, and its research is more and more extensive. In order to demonstrate that the blended-wing-body underwater glider has the advantage of hydrodynamic characteristics compared with the traditional underwater glider with equal volume, two kinds of underwater gliders are selected for three-dimensional modeling, and their internal volume is controlled to be equal. Computational fluid dynamics method is used to simulate the two models at different speeds and different angles of attack, and the hydrodynamic performance of the two models is compared and analyzed. The conclusion shows that under the condition of equal volume, the maximum lift-drag ratio of the blended-wing-body underwater glider is 2.3 times higher than that of the traditional underwater glider.
