Abstract
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.
