The invention provides a high-lift hydrofoil suitable for large-depth forced sinking of an underwater towed body and the underwater towed body, and is characterized in that the high-lift hydrofoil comprises a middle rectangular wing, two side wings, a transition part and a fusion type small wing; two side wings extend from the two sides of the middle rectangular wing, and the sides, away from the middle rectangular wing, of the two side wings are connected with the fusion type winglet through transition parts; the whole hydrofoil is triangular, the middle rectangular wing is rectangular, the side wings on the two sides contract towards the tail edge of the hydrofoil, and the contraction positions of the side wings on the two sides are connected with the fusion type winglet. The underwater towed body has a higher lift coefficient (the maximum lift coefficient is increased by 85% compared with that of a common rectangular hydrofoil), a smaller wing surface area is designed on the premise of providing the same forced sinking force, and the design size of the underwater towed body can be effectively reduced.
本发明提供了一种适用于水下拖体大深度迫沉的高升力水翼及水下拖体,其特征在于,包括:中部矩形翼、两边侧翼、过渡部分以及融合式小翼;所述中部矩形翼的两侧延伸出两边侧翼,所述两边侧翼远离所述中部矩形翼的一侧通过过渡部分连接所述融合式小翼;水翼整体呈三角形,所述中部矩形翼为矩形,所述两边侧翼朝向水翼的尾缘收缩,所述两边侧翼的收缩处连接所述融合式小翼。本申请具有更高的升力系数(与常用矩形水翼相比最大升力系数提高了85%),在提供相同迫沉力的前提下设计更小的翼面面积,可以有效地减小水下拖体的设计尺寸。
