摘  要：為進一步提高海洋拖曳系統的定深性能，以滿足部分拖曳系統的高拖曳速度、大工作深度的需求，針對常規海洋拖曳體存在的控制機構復雜、體積大、定深特性較差等問題，提出一種結構簡單、體積小、定深特性好的雙三角翼型拖曳體設計思想，并在拖曳水池完成這一新型拖曳體定深特性的水動力實驗研究。結果表明：調整次纜長度比例關系、改變水翼張角等方式可以改變拖曳體的定深性能，且相對而言，調整次纜長度比例關系對于拖曳體定深特性的影響更為明顯。實驗結論不僅證明了雙三角翼型拖曳體良好的定深特性，并可為雙三角翼型拖曳體結構優化以及控制方法設計等提供重要依據。

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.
