Background

As a device for controlling the ship course, the rudder mainly has the function of ensuring the ship maneuverability and is the most widely used manipulating device at present. The rudder consists of a steering device and a rudder blade, wherein the rudder blade is a rotatable plate with a streamline section and positioned behind the ship, and hydrodynamic force is generated by the rudder blade. When the rudder blade has a certain rudder angle, the symmetry of water flow relative to the rudder blade is broken, a pressure difference is formed between the incident flow surface and the back flow surface of the rudder blade, a transverse force and a turning moment around the gravity center of the ship are generated by the pressure difference, the ship body is further deflected relative to the water flow, and the hydrodynamic performance of the rudder blade has obvious influence on the maneuverability of the ship.

The existing marine rudder section is mainly of a symmetrical wing type, the water flow velocity and the pressure distribution of the incident flow surface and the back flow surface near the tail edge of the rudder blade are approximately equal in the steering state, the generation of pressure difference is not facilitated, and the steering effect is low.
