Analysis of Hydrodynamic Characteristics of UUVs with Cross-fin/X-rudder Layout

摘要:

无人水下航行器（Unmanned Underwater Vehicles，UUV）的鳍舵布局形式是 UUV 总体设计过程中的重要组成部分，直接决定着 UUV 的航行性能。研究了一种十字型鳍 X 型舵布局下 UUV 的流体动力特性， 建立了 UUV 流体动力计算流程，包括几何建模、网格划分和流体动力仿真的基本方法，分析了十字型鳍 X 型舵布局 UUV 本体的流体动力特性。研究结果表明：十字型鳍 X 字型舵布局 UUV 的平衡攻角和平衡舵角均满足设计要求，是一种有效的操纵面布局形式。

Abstract:

The fin-rudder layout of unmanned underwater vehicles（UUVs）is an important part of UUV overall design，which directly determines the navigation performance of the UUV. The fluid dynamic characteristics of UUVs with cross-fin/X-rudder layout are studied in this paper. The UUV hydrodynamic calculation flow is established，including the basic methods of geometric modeling，grid division and hydrodynamic simulation. The hydrodynamic properties of the UUV with cross-fin/X-rudder layout are analyzed. The research results show that the equilibrium angle of attack and equilibrium rudder angle of the UUV meet the design requirements，and it is an effective layout for surface control.
