Lift propeller ship

Abstract

The invention discloses a lift propeller ship and relates to a novel ship. The invention discloses the novel ship, which has the principle that by utilizing the special fluid mechanical properties of propellers on an interface between two fluids (water and air), the bottom part of the ship is provided with a set of vertical lift propellers (2); the ship (1) is lifted out of a water surface by lift generated when the vertical lift propellers (2) work, so that the ship (1) is always in the state of floating on the water surface, thereby, the resistance when the ship sails is greatly reduced. In order to eliminate the influences generated by waves, the vertical lift propellers (2) are connected through a hydraulic system, and the pressure of each propeller is evenly distributed. The ship forwarding power is provided by a propulsive fan (3) arranged at the stern part of the ship, and in order to improve the propulsive efficiency, a water curtain pressurization device (4) is arranged at the rear of the propulsive fan (3). As the block coefficient of the ship body approaches to 1, the draft of the ship is very shallow when the ship is anchored, and the draft requirement on an anchoring dock is reduced.

Description

[technical field] [0001] The invention relates to a new type of ship, especially a shallow draft ship. [Background technique] [0002] Existing ship type, with regard to ship's floating state mode, has displacement type, hydrofoil type, air cushion type, also does not have the lift type that propeller is vertically provided with and the ship is raised. [Content of the invention] [0003] The purpose of the present invention is to provide a new type of ship, which has zero draft when sailing and floats on the water. [0004] In order to achieve the above object, the lift propeller ship of the present invention uses the special hydrodynamic properties of the propeller on the interface between two fluids (water, air), and sets a group of vertical lift propellers at the bottom of the ship. 2. [0005] When at anchor, the ship's floating mode is still displacement, see figure 1 . When sailing, the vertical lift propeller 2 starts to work, and the lift produced lifts the shi...
