SUBMARINE IN WHICH DIRECTION IS CONTROLLED USING BUOYANCY

WIPO Patent Application WO/2015/102421

A1

The present invention relates to a submarine in which direction is controlled using buoyancy. Air bags are formed at the front and rear of the submarine and the front and rear air bags are separated or connected. In the case where the air bags are separated, a compressed-air tank is formed, the air in the air bags is sucked and compressed by an air compressor of the compressed-air tank, and the air is emitted by the opening and closing of a valve; or in the case where the front and rear air bags are connected, the air is sent to the front or the rear by an air pump, thereby allowing the up and down direction of the submarine to be controlled due to a difference in buoyancy between the front and the rear of the submarine body. With regard to the change in the left and right direction, elastic air bags are formed on the left and right of the submarine and the left and right air bags are separated or connected. In the case where the air bags are separated, air is inserted or removed by means of the air compressor of the compressed-air tank; or in the case where the air bags are connected, the air is sent to the left and the right by the air pump, thereby allowing the direction to be more easily controlled due to a difference in buoyancy between the left and the right of the submarine body when the change in the left and right direction of the submarine is controlled by left and right direction control wings.
