二体水下拖曳系统的试验研究

介绍了一种将传感器测量法应用于船模试验水池中进行水下拖曳系统模型试验的方法，并借助这一方法探讨了二体水下拖曳系统的水动力性能。试验结果表明：将传感器测量法应用于船模试验水池中进行水下拖曳系统的试验可以取得令人满意的效果，它为水下拖曳系统模型试验提供了一种理想的手段；二体水下拖曳是一种使水下拖体在波浪环境下作业时保持稳定的简便、经济的水下拖曳方式，它能有效地减少拖曳点对水下拖体的波频扰动，保证水下拖体在恶劣的海洋环境下拖曳时的姿态稳定，是一种值得发展的水下拖曳系统。

An Experimental Study of a Two-Part Underwater Towed System

An experimental technique for testing the underwater towed system in a model ship towing tank with sensor measurements is proposed and the hydrodynamic behaviours of a two_part underwater towed system with such a technique are demonstrated. The experimental results shows that optimal results of an underwater towed system test conducted in a model ship towing tank can be achieved with the technique. The method provides an ideal means for laboratory experiments on an underwater towed system. The two_part towing is an easy and cost_effect way to maintain an underwater towed vehicle stable in waves. It can decouple surface towing point motions from the towed vehicle and ensure the vehicle stable under severe ocean environments. This is a new type of underwater towed system which deserves further development.
