为了研究水下无人航行器(unmanned underwater vehicle,UUV)的外形因素对阻力性能的影响,利用计算流体力学方法对不同航行器外形展开阻力预报及分析.对于水下高速UUV而言,优异的阻力性能对UUV的航速和续航能力的提升都是至关重要的.针对某高速UUV的减阻需求,首先结合SUBOFF标准模型进行了阻力特性数值预报,与试验数据对比验证了预报方法的适用性;在此基础上,模仿鲨鱼和海豚的外形特征设计了 2 种UUV水动力外形构型,针对 2 种外形构型分别预报了带有不同附体构型的阻力特性,得到了一种相比SUBOFF艇形具有明显减阻效果的UUV水动力外形.研究对低阻型高速UUV的外形设计具有一定的参考价值.
Research on biomimetic shape design and drag numerical prediction of high-speed UUV
In order to study the influence of the shape factor of unmanned underwater vehicle(UUV)on the drag performance,the computational fluid dynamics method was used to predict and analyze the drag of different vehicle shapes.For high-speed UUV,excellent drag performance is crucial for both speed and endurance of UUV.Aiming at the drag reduction requirements for a high-speed UUV,the numerical prediction of the drag characteristics was first carried out based on the SUBOFF standard model,and the applicability of the prediction method was verified by comparing with the test data.Based on this,two UUV hydrodynamic shapes with design features resembling sharks and dolphins were created,and the drag characteristics with different attachment configurations were predicted for each shape.Compared with the SUBOFF hull form,one UUV hydrodynamic shape was found to have a significantly reduced drag,providing valuable references for the design of low-drag,high-speed UUV.
