Ship propelled through front resistance elimination and rear pressure increase

Abstract

The invention discloses a ship propelled through front resistance elimination and rear pressure increase. The ship comprises a ship body, rudder blades and a propeller and is characterized in that a water flow channel communicated with the front end and rear end of the ship body and capable of making water flow pass from the position under the ship body is arranged under the ship body, a water inlet sump and a water outlet sump are formed in the front end and the rear end of the ship body, two ends of the water flow channel are communicated with the water inlet sump and the water outlet sump respectively, and the propeller is arranged in the water inlet sump or the water outlet sump. The shape resistance and wave-making resistance exerted to the ship body can be decreased by swallowing coming water from the front end of the ship body through rotation of the propeller in the running process, the swallowed water is discharged from the tail of the ship so as to propel the ship body to advance, and an energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a propulsion ship with front resistance elimination and rear pressure increase. Background technique [0002] A boat is a means of transportation that can be parked and run on water, which can bring convenience for travel, play or water operations. [0003] The existing ships have the following deficiencies: [0004] 1. Due to the water discharge at the front of the hull when moving forward, the shape resistance and wave-making resistance on the hull are relatively large, resulting in high energy consumption; [0005] 2. The rudder blades are located behind the hull, but the hull is long, the radius of the turning track is large, and the maneuverability is poor; [0006] 3. When the ships travel in tandem, the front end of each hull will generate resistance. Contents of the invention [0007] Aiming at the deficiencies of the prior art, the present invention discloses a...
