摘  要：为进一步提高海洋拖曳系统的定深性能，以满足部分拖曳系统的高拖曳速度、大工作深度的需求，针对常规海洋拖曳体存在的控制机构复杂、体积大、定深特性较差等问题，提出一种结构简单、体积小、定深特性好的双三角翼型拖曳体设计思想，并在拖曳水池完成这一新型拖曳体定深特性的水动力实验研究。结果表明：调整次缆长度比例关系、改变水翼张角等方式可以改变拖曳体的定深性能，且相对而言，调整次缆长度比例关系对于拖曳体定深特性的影响更为明显。实验结论不仅证明了双三角翼型拖曳体良好的定深特性，并可为双三角翼型拖曳体结构优化以及控制方法设计等提供重要依据。

Abstract: In order to satisfy the high towing speed and deep-working requirements of some underwater towed systems， a new design scheme of towed vehicle with double triangle wings was proposed to solve problems such as the control structure of underwater towed vehicle is complicated， volume is large and the characteristic of depressive depth is bad normally. The experiment on the characteristic of depressive of this towed vehicle was operated in the towed bank. The experimental results show that the measures changing the length of secondary towed cable and angle of wing influence the lift-drag ratio of towed vehicle. In comparison， the influence of changing the towed cable ratio is more obvious. The conclusions show the favorable depressor characteristic of towed vehicle with double triangle wings. Moreover， it can be used to optimize the structure of towed vehicle and design the control method.
