Rudder Stabilization Energy Saving System

Abstract

The invention discloses a ship rudder stabilization and energy-saving system, and relates to the technical field of ships. Specifically, it is composed of a rudder stabilizing diverter unit, a rudder empennage 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 deflector stabilization unit includes a steering plate deflector and a horizontal shafting deflector; the rudder empennage stabilization unit includes a rhomboid empennage and a composite joint surface; the lower arc energy-saving unit of the rudder steering plate includes a lower arc The vertical height position of the line apex; the ladder line energy-saving unit on the rudder steering plate includes the vertical height position of the trapezoid and the trapezoidal waist; the rudder control energy-saving unit is the horizontal position of the lower arc and the apex position of the upper ladder platform, The torsion golden centerline formed by the line connecting two points. The invention reduces the vibration of the rudder, improves the stability of the rudder, reduces the flow resistance of the rudder and controls the torque, and enhances the precision, directivity, response speed and service life of the rudder.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a rudder stabilization energy-saving system. Background technique [0002] The ship relied on the high-speed continuous rotation of the propeller blades to paddle the water to bring horizontal main thrust, and the ship controlled the sailing direction by operating the deflection of the rudder. When the propeller is rowing, in addition to the horizontal thrust, harmful vortices with the propeller as the vortex are also derived. The vortex takes the center of the horizontal axis of the propeller as the center to the outward and far ends. The horizontal and vertical flow forces are not uniformly dispersed, and the vortex flow force follows the propeller. The rotation speed changes in real time. When the vortex flow 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...

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
