Abstract:

A control system for a supercavitating vehicle includes a set of winglets for rapid maneuverability and a segmented ring wing for fine stabilization control. The winglets and ring wing extend from an aft portion of the vehicle. The winglets are supported by a strut attached to the vehicle. The angle of attack of each winglet into the water adjacent the cavity is controlled by a winglet actuator. The winglet assembly may be extended into the water or retracted to be completely within the cavity by means of a spring-loaded actuated mount. The segmented ring wing is controlled by a ring actuator. The ring actuator may be used to control the angle of attack of the ring wing. Alternately, or in combination the flow over the ring wing may be neutralized by using the cavitator of the vehicle to globally enlarge the cavity and thus limit the flow.
