Study on Design of Shape and Hydrodynamic Layout for Ultra-low-speed AUV

College of Marine Engineering, Northwestern Polytechnical University, Xi′an 710072, China

摘要: 超低速自主式水下航行器(AUV)是AUV技术研究的新领域。如何在超低速(<0.5 kn)情况下获得良好的航行稳定性能是超低速航行器技术研究的主要内容之一。针对超低速小型AUV的水下布放与回收的特点, 提出了一种基于回转体外形的超低速小型航行器外形及流体动力布局设计方案, 着重解决AUV在超低速航行的高稳定性要求, 经过理论估算和FLUENT软件仿真验证, 仿真结果满足设计要求, 对深入研究低速高稳定性小型水下航行器具有重要的参考价值。

Abstract: An axisymmetric body based scheme of shape and hydrodynamic layout for an ultra-low-speed autonomous underwater vehicle (AUV) is presented to obtain high stability at low speed (<0.5kn) according to the characteristics of its underwater laying and recovery. Theoretical calculation and simulation with the software FLUENT verify that the scheme may be taken as a reference in the study of ultra-low-speed AUV.
