摘要
为了获得最优的GPS天线线型,以某AUV为母型,采用ICEM-CFD、Fluent等CFD软件,结合RANS方法和SSTκ-ω模型对搭载不同线型GPS天线的AUV进行数值计算。研究结果表明,对GPS天线设计后掠角可以有效降低天线的阻力,从而降低AUV受到的整体阻力。具有一定后掠角和尾端曲线的GPS天线有利于改善AUV尾部伴流特性,减小桨盘面伴流速度的不均匀度。
In order to obtain the optimal form of GPS antenna, numerical calculation on AUVs which carry different kinds of GPS antennas is conducted using RANS method and SST κ-ω turbulence mode based on a mini-AUV. The results of research show that GPS antenna with top rake can reduce the resistance and the total resistance of AUV efficiently. GPS antenna which has top rake and curve in the end has a positive influence on the flow performance of tail. It also can reduce the unevenness of flow speed in the propeller disk.
