Abstract

The invention relates to a ship body structure deeply coupled with a water jet propulsion device, which belongs to the technical field of ship design. The ship body structure comprises a ship body anda water jet propulsion device, wherein a tunnel for mounting the water jet propulsion device is arranged at the bottom of the tail of the ship body; and the water jet propulsion device is arranged inthe tunnel. The axis of the tunnel is located below the waterline, and the water jet propulsion device is integrally embedded into the tunnel and connected with the transmission shaft. According to the ship structure, the water jet propulsion device and the ship body structure are integrated and coupled with water power, the problem that the propulsion efficiency of a water jet propulsion ship within the navigation speed range of 18-30 kn is low can be solved, integration of the ship body and a propeller from the structure to the water power performance is achieved, and further development ofthe ship structure and the propulsion technology is promoted. The water jet propulsion ship disclosed by the invention has excellent rapidity, maneuverability and cavitation resistance of the propeller within a relatively wide navigation speed range.

Description

technical field [0001] The invention relates to a ship hull configuration deeply coupled with a water jet propulsion device, and belongs to the technical field of ship design. Background technique [0002] At present, there are two types of water-jet propulsion ships. One is to place the propulsion device in the hull, and the pump body of the device is fixed on the stern plate. The propulsion pump is introduced, and the speed of this type of water jet propulsion ship is generally above 30kn. The other is that the water-jet propulsion device is suspended at the bottom of the ship, and the device and the hull are clearly defined. This type of propulsion device is called a water-jet propulsion combination, and is generally used for medium-low speed and heavy-duty ships with a speed of less than 18kn. At present, these two types of water-jet propulsion ships have low propulsion efficiency in the speed range of 18-30kn. Therefore, the technical field needs to solve the problem ...
