ABSTRACT:
Vane members are movably mounted on the hulls of watercraft to serve steering and stabilization functions. Several embodiments are provided, some of which rotate between extended and shielded positions, others of which fold to vary the angle at which they extend from their associated hull, and still others of which both rotate and fold to facilitate storage alongside planar hull portions. Both shaft and surface bearing vane mounting systems are described. In preferred practice, the vanes are used on hydrofoil-carrying semi-displacement ships, and the provision of stowably mounted hydrofoils, planing surfaces, and wave form generators on such ships is also provided. Such vane members are also provided on vehicles operable in a fluid medium, such as torpedos operable completely submerged in water, and aerial vehicles such as missiles and aircraft of both the rotary wing and fixed wing types, to similarly serve steering and stabilization functions.
