水下滑翔机常用于对海洋环境长时间、大范围的实时监测，需具备优良的水动力特性。论文主要研究滑翔机整机主体外形和机翼后掠角对水动力性能的影响，从阻力、功转换率及重心偏移量等多方面对水下滑翔机的性能进行评估，并从流动结构的角度探究原因。

Underwater gliders are commonly used in marine environment for long-term and large scope of real-time monitoring, which are required to have excellent hydrodynamic characteristics. This paper studies how the body shape and sweep back angle effect on the hydrodynamic performance of gliders. Performances of underwater glider with different body shapes and swept-back angles are evaluated, such as drag, power conversion ratio and barycenter's offset, and the reasons are analyzed with the help of flow state of the airfoil.
