ATTITUDE-ADAPTIVE HYDROFOIL APPARATUS FOR HIGH-SPEED UNDERWATER TOWING OPERATION

摘要

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.

1. A hydrofoil apparatus, comprising:
a) strut-braced wing assemblies, the strut-braced wing assemblies each comprising a bearing, at least one inclined tube, at least one inclined flow-guiding wing, and at least one stop dog; b) a horizontal wing assembly, the horizontal wing assembly comprising a horizontal tube, at least one horizontal flow-guiding wing, and at least one depth-locating wing; c) connection plates; and d) attack angle adjusting plates, the attack angle adjusting plates each comprising an angle adjusting end plate having a hole;wherein
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 at least one inclined tube comprises a first ear plate, and the era plate is connected to the bearing via an anchor shackle and an anchor swivel; a lower end of the at least one inclined tube is connected to the horizontal wing assembly via the connection plates and the attack angle adjusting plates; the at least one horizontal flow-guiding wing and at least one depth-locating wing are sleeved on the horizontal tube; the attack angle adjusting plates are disposed at two ends of the horizontal tube, respectively; an angle adjustment bolt is inserted into the hole of the angle adjusting end plate and is fixed by an angle adjustment nut; and in use, an attack angle of the at least one depth-locating wing is determined by the at least one inclined tube, the angle adjustment bolt, and the angle adjustment nut.
