An experimental study on hydrodynamic characteristics of Gliding-Hydrofoil Craft

The Gliding-Hydrofoil Craft (GHC) has been recently proposed by the authors from JUST, which is partially similar to a planing craft but has a hydrofoil installed in the front part of the ship. To study its hydrodynamic characteristics, model tests are carried out in a towing tank, and the total resistance, trim angle and wetted area of the craft in the cases with different Froude numbers are measured. This paper presents analysis on the experimental data and discusses the effects of the submerged depth and initial attack angle of the hydrofoil.
