WAVE PROPULSOR AUTOMATIC CONTROL DEVICE Russian patent published in 2002 - IPC

FIELD: utilization of sea wave energy for ship's motion. SUBSTANCE: control wing 1 is connected with controllable wing 2 by means of kinematic linkage including wheels 6 and 7 of equal diameter interconnected by means of flexible coupling and mounted on stocks 3 and 4. Turn of wheel 6 on stock 3 is limited by circular stop. Wheel 7 is rigidly fitted on stock 4. Controllable wing 2 is held in position when its chord is parallel to axis of housing 5 by means of springs 11. Control wing 1 follows up rake angle and turns controllable wing 2 when angle limited by circular stop has been attained. EFFECT: operation of controllable wing 2 at optimal angle of attack. 2 cl, 3 dwg
