Abstract : An actuator mechanism for operating the shutter door of a torpedo tube includes two hydraulic cylinders connected in series and a plurality of interconnected links pivotally connected between the inner hull and the shutter door. In operation, the combined movement of the hydraulic cylinders rotates an elongated torque arm and a transfer link about a rotatable shaft. As the transfer link rotates it moves the end of the link inwardly away from the outer hull. As the transfer link further rotates away from the outer hull, it draws the connector link and the shutter door inwardly. The added throw of the two cylinders cooperate with the longer torque arm to provide an increased moment, and hence greater opening force on the shutter door.
