System for effectively increasing the stroke range of an actuator and deflection angle of a fluid hinge trim tab system for attitude control and stabilization of a watercraft

摘要

A system and method for effectively increasing the stroke range of an actuator and deflection angle of a fluid hinge trim tab system for attitude control and stabilization of a water craft includes at least one actuator (20), a scissor joint (25) made up of a rigid structural member (27) and hinge member (33), a scissor hinge mount (35), and an elongate substantially planar surface (32). The scissor joint (25) is connected to the scissor hinge mount (35) and the elongate substantially planar surface (32) at opposite ends. Extension of actuator ram (36) allows for rotation of the rigid structural member (27) which creates a rotational angle (48) and an angle of deflection (40) between the elongate substantially planar surface (32) and the hull (21) of the water craft, which effectively increases the stroke length of the actuator (20). The system also allows for retraction of the actuator (20).
