Abstract

The invention discloses a low resistance air cushion craft. The low resistance air cushion craft comprises a craft body and a buoyancy device installed at the periphery of the craft body, the periphery of the craft body is provided with borders, the border is provided with a mounting hole, the mounting hole is connected to the buoyancy device, the buoyancy device comprises a connecting rod, a buoy and an air cushion, the air cushion is connected to the buoy, the buoy is connected to the connecting rod, the connecting rod is located at the mounting hole, is connected to the border through a bolt, and is provided with a spring, the spring is connected to the border and the buoy, the connecting rod is provided with a pin hole, the pin hole is connected to the border through a dowel, and the buoy comprises a plastic hollow buoy or a foam buoy. The low resistance air cushion craft is simple in structure and convenient to use, through the use of the air cushion and the buoy, the resistance between the craft body and the water surface is reduced, and thus power output is lowered; moreover, the craft is safe in use, has a recreation function and is suitable for an aquatic recreational place.

Description

technical field

[0001] The invention relates to the technical field of boats, in particular to a low-resistance hovercraft. Background technique

[0002] Objects moving in water are more resisted by water than in air, because the density of water is about 800 times that of air, so the resistance of objects moving in water is about 800 times that of moving in air. The reason why a ship cannot run fast in the water is the resistance of the water. When the ship runs fast, the resistance of the water also increases sharply. The water resistance hinders the speed of the ship. According to experiments, the speed of the ship has three parts: One is the frictional force, which is produced by the friction between the surface of the hull and the water flow. The larger the area of ​​the hull in contact with water, the greater the frictional resistance. The second is wave-making resistance, which is formed by waves arising from the ship's navigation in the water; the third is eddy curr...
