作为水下航行体操纵性水动力系数之一,线性速度系数的准确预报对操纵性设计具有重要意义。通过与水平面平面运动机构模型试验的线性速度系数数据对比,建立了线性速度系数的数值计算方法。在此基础上研究模型试验中安装模型用的支杆对Suboff模型线性速度系数的影响,对比分析了有无支杆状态下水下航行体表面压力及流线分布特性。
As one of the maneuvering hydrodynamic coefficient, accurately predicting linear velocity coefficient has great significance in maneuverability design. Comparing with experimental data based on horizontal planar motion mechanism test, a numerical method for linear velocity coefficient prediction is presented. Then the influence of sting on linear velocity coefficient is analyzed, which is installed on the SUBOFF model. The performance influence of the sting on the pressure and streamline on the hull surface is conducted.
