水下无人航行器外挂吊舱水动力试验及操纵性分析

在循环水槽开展了某带吊舱水下无人航行器的水动力试验,绘制出了航行器阻力曲线,得到了与操纵性相关的主要水动力系数,在此基础上对水下无人航行器的运动稳定性进行了分析,并与不带吊舱情况下的水下无人航行器操纵性进行了比较。试验结果可为水下无人航行器推进系统设计及运动控制与仿真提供依据。

Hydrodynamic experiment and maneuverability analysis of an unmanned underwater vehicle with an outside equipment cabin

The hydrodynamic experiment to the model of an unmanned underwater vehicle with an outside equipment cabin was done in circulating water channel. According to the results of the experiment, the re-sistance curve of the vehicle, and the main hydrodynamic coefficients were obtained. Utilizing the coeffi-cients, the stability of motion of the vehicle was analyzed and the maneuverability of this vehicle was com-pared with the vehicle without the cabin. To the underwater vehicle, results from the experiment could pro-vide the base of the propeller design and motion simulation and control.
