Problems solved by technology

[0003] The profile of the existing marine rudder is mainly a symmetrical airfoil. In the steering state, the flow velocity and pressure distribution on the upstream and downstream surfaces near the trailing edge of the rudder blade are almost equal, which is not conducive to the generation of pressure difference and the rudder efficiency is low.

Abstract

The invention discloses a spoiler rudder for coordinated control of a ship, which comprises a rudder blade, a first spoiler plate and a second spoiler plate; the first spoiler plate and the second spoiler plate are hinged on different rudder surfaces; There is a drive system, the first drive system is used to drive the first spoiler to rotate, so that the trailing edge of the first spoiler is close to or away from the trailing edge of the rudder blade, and the second drive system is used to drive the second spoiler to rotate, Move the trailing edge of the second spoiler closer to or away from the trailing edge of the rudder blade. The invention discloses a cooperatively controlled marine spoiler rudder, in which spoilers are respectively arranged on the two rudder surfaces at the tail of the rudder, and the spoiler is rotated by a drive system, and the corresponding spoiler is opened as required when steering the rudder , to obtain higher rudder efficiency, when going straight or reversing, close the two spoilers at the same time to form a streamlined rudder shape, reduce the resistance of the rudder, and improve the performance of going straight or reversing.

Description

technical field [0001] The invention relates to the field of marine rudders, in particular to a coordinated control marine spoiler rudder. Background technique [0002] As a device for controlling the course of a ship, the main function of the rudder is to ensure the maneuverability of the ship, and it is currently the most widely used steering device. The rudder is composed of a steering gear and a rudder blade. The rudder blade is a rotatable board with a streamlined section located behind the ship, and the hydrodynamic force is generated by the rudder blade. When the rudder blade has a certain rudder angle, because the symmetry of the water flow relative to the rudder blade is destroyed, a pressure difference is formed between the upstream and downstream surfaces of the rudder blade, and a lateral force and a rotational moment around the center of gravity of the ship are generated by the pressure difference. When the hull is deflected relative to the water flow, the hydr...
