Abstract:

The power requirements for control of a hydrofoil ship in a random sea are examined using control systems designed through minimization of a cost function consisting of a linear combination of heave acceleration and control power. Four hydrofoil configurations are compared using ship parameters representative of the USS PLAINVIEW, a 300 ton U. S. Navy hydrofoil ship in which ship pitch dynamics have been neglected. It is found that a configuration consisting of a pivoted foil with a trailing edge tab for incidence angle control consumes the least power for a given ship response followed by a configuration consisting of a fixed foil with a trailing edge flap.
