基于约束模型试验的无人帆船速度预报

小型无人帆船在海洋观测领域具有广泛应用前景，而速度极曲线图是无人帆船设计和应用的重要基础。针对一条小型无人帆船的风帆选型问题，采用约束模型试验方法建立了4自由度动力学方程，并借助静态速度预报程序VPP获得了完整的速度极曲线图。基于不同方案的速度极曲线对比，实现了风帆选型的设计目标。为小型无人帆船的速度预报提供了适用的技术手段，对小型无人帆船的设计评估和设计优化具有重要借鉴意义。

Velocity Prediction of Unmanned Sailboat Based On the Captive Model Test

Small unmanned sailboat is playing an increasingly important role in marine data monitoring. The velocity polar diagram is the basis for design and manipulation of any unmanned sailboat. For consideration of two different sail wings, the captive model tests were employed to establish the 4-DOF dynamic equations, and static Velocity Prediction Program was developed to obtain the velocity polar diagrams. The better sail wing is selected based on the comparison of two different diagrams. The research is valuable for design evaluation and optimization of any small unmanned sailboat.
