Abstract : The solution is presented of an idealized problem involving the towing of a hydrofoilstrut system in a still fluid. The system consists of a hydrofoil of finite mass connected to the towing vehicle (towpoint) by a rigid strut of constant crosssection and uniform mass distribution, the hydrofoil being attached to the strut end in such a way that it always operates at a fixed lift coefficient. The towpoint moves in a circular path with constant speed and both strut and foil are restricted to the plane of the towpoint's motion. The hydrodynamic force assumed to act on the strut is that commonly used for flexible cables; i.e., a running normal load proportional to the square of the normal component of local velocity. Thus, fluid tangential (friction) forces are neglected as well as those reactions (virtual mass effects) associated with perfect fluids. In addition to the absence of gravity, the other simplifying assumption used is the neglect of hydrofoil drag. (Author)
