姿态自适应水下高速拖曳水翼装置
摘要：
一种姿态自适应水下高速拖曳水翼装置，属于水下拖曳技术领域领域。该装置包括斜拉翼和水平翼部分，整体呈U形状，布置左右对称。斜拉导流翼套在斜拉翼管上，可自由转动，有利于减少装置整体的阻力以及避免涡激振动，保证装置的安全性与稳定性。水平导流翼套在水平翼管上。定深翼的攻角大小由角度微调螺母调节。船舶有速度时，定深翼产生向下升力，使得拖曳装置保持在一定水深，且左右对称的布置保证了水平翼能够自动调整姿态，以保持水平状态。该装置结构简单，操作方便，安全可靠，实用性强，适用于船舶高速下拖曳水翼的使用。
摘要（英）：

An attitude-adaptive hydrofoil apparatus, including: strut-braced wing assemblies, a horizontal wing assembly, connection plates, and attack angle adjusting plates. The strut-braced wing assemblies each include a bearing, at least one inclined tube, at least one inclined flow-guiding wing, and at least one stop dog. The horizontal wing assembly includes a horizontal tube, at least one horizontal flow-guiding wing, and at least one depth-locating wing. The attack angle adjusting plates each include an angle adjusting end plate having a hole. The strut-braced wing assemblies are symmetrically disposed at two sides of the horizontal wing assembly. The bearing is fixed on a vessel body by welding. The at least one inclined flow-guiding wing is sleeved on the at least one inclined tube, and is limited by the at least one stop dog. The attack angle adjusting plates are disposed at two ends of the horizontal tube, respectively.
