Rudder stabilizing and energy-saving system

Abstract

The invention discloses a rudder stabilizing and energy-saving system and relates to the technical field of ships. The system specifically comprises a rudder stabilizing flow guide body unit, a rudderempennage stabilizing unit, a rudder lower arc energy-saving unit, a rudder upper ladder line energy-saving unit and a rudder control energy-saving unit; the rudder flow guide body stabilizing unit comprises a direction plate flow guide body and a horizontal shafting flow guide body; the rudder empennage stabilizing unit comprises a rhombic empennage and a composite junction surface; the rudder lower arc energy-saving unit comprises a vertical height position of a lower arc vertex; the rudder upper ladder line energy-saving unit comprises a trapezoidal vertical height position and a trapezoidal waist; the rudder control energy-saving unit is a torsion gold center line formed by the connecting line of a lower arc horizontal position and an upper ladder terrace vertex position. With the system adopted, the jitter of a rudder is reduced, the stability of the rudder is improved, the flow resistance and control torsion of the rudder are reduced, the accuracy, directivity and reaction speedof the rudder are improved, and the service life of a shafting system is prolonged.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a rudder stabilization and energy-saving system. Background technique [0002] The ship relies on the high-speed continuous rotation of the propeller blades to paddle water, bringing horizontal main thrust, and the ship controls the direction of navigation by operating the deflection of the rudder. When the propeller paddles water, in addition to the horizontal thrust, a harmful vortex with the propeller as the center is also derived. The vortex is centered on the center of the horizontal axis of the propeller and goes outward and far away. The horizontal and vertical flow forces are not evenly dispersed. The speed changes in real time. When the vortex force acts on the side of the rudder steering plate and is blocked, the force on the side of the rudder steering plate is unbalanced, resulting in continuous shaking of the rudder steering plate up and down and left and right. The gr...

AI Technical Summary

Problems solved by technology

The decrease in the stability of the rudder increases the torque controlling the rudder and creates new water flow disturbances, the flow resistance of the rudder increases, the directional control accuracy, directivity, and response speed of the rudder decrease, and the rudder shaft system is vulnerable

At the same time, the greater the torque controlling the rudder and the greater the resistance of the rudder, the greater the energy loss and the shorter the service life of the rudder
