Abstract:

An investigation is made to determine desirable sizes and longitudinal locations of foils to provide vertical plane stability for a 2000-ton Hydrofoil Small Waterplane Area Ship HYSWAS. After determination of the foil size and locations, the motion of the ship in regular head waves is computed and the probable range of the rate of foil deflections for the control of heave and pitch motion is examined. Within the scope of this analysis, it is found that a proper selection of size and location of foils will provide the vertical-plane stability up to 50 knots and that the required foil deflection rates are considered to be practical.
