NON-OSCILLATING SEMI-DIVING TYPE WATER SURFACE SAILING SHIP

摘要

PURPOSE:To suppress vertical oscillation by using a strut body structure as a body structure formed so that the connecting strength between a lower hull and an upper hull can be maintained, and disposing this body structure in the mid-ship part of the lower hull to reduce the changing quantity of ship body floating force by waves in the bow and stern. CONSTITUTION:A lower hull 1 is connected to an upper hull 2 through a strut 3, and a movable transverse rudder 4 for suppressing vertical and transverse oscillation and a vertical rudder 5 for converting the forward direction of the ship are provided in the lower hull 1. In this case, a strut body structure 3 having a small water line area which makes reserve buoyancy extremely small is disposed in the mid-ship part of the lower hull 1, and an extended swollen construction 7 provided with a part or all of a device of big driving force is formed in the mid-ship part of the lower hull 1 to suppress vertical oscillation. According to this constitution, oscillation can be eliminated.
