LARGE HYDROFOIL SHIPS FEASIBILITY LEVEL CHARACTERISTICS

An analytical approach encompassing the preliminary feasibility level considerations necessary for determining the configuration definition, design and performance of hydrofoil platforms in the systems analysis context has been developed. The relationships among full load displacement, horsepower take-off margin, maximum speed capability, endurance, and range are examined for twenty-four configuration candidates (400-2000 tons) derived by varying powerplant shafthorsepower (30000-50000), foil loading (800-1200 psf), and propulsor (propeller-waterjet) parameters. The design criteria employed pertain to minimum take-off margin (25 percent maximum available horsepower) and maximum speed attainable (50 knots). The resulting performance characteristics are examined for constant speed operation and an alternating sprint/drift speed mode. The identified parametric inter-relationships and their sensitivities are systematically explored and summarized, enabling the designer/analyst to evaluate alternatives via the desired criterion.
