The rudder angle meter can reflect the rudder angle of the propeller, and always control the ship to maintain the correct heading. The multi-angle display of the marine rudder angle meter includes a console. The console is provided with an inclined surface, and the inclined surface is inlaid with Compass type rudder angle meter and digital type rudder angle meter, the upper side of the console is provided with a turntable type rudder angle meter, the precision of the turntable type rudder angle meter is greater than that of the compass type rudder angle meter, and the interior of the console There is a support plate, a large gear is arranged in the middle of the support plate, and three pinions are arranged around the large gear. The large gear and the pinion are meshed and connected.
Principle: Marine rudder is a flat plate or wing structure with a small aspect ratio (that is, the ratio of rudder height to rudder width). When the rudder rotates, the force acting on the rudder blade can be decomposed into rudder resistance and rudder lift. The rudder resistance is along the direction of fluid flow (that is, the direction of the ship's sailing), and the rudder lift is perpendicular to the fluid flow. The rudder lift will generate a rudder turning moment relative to the midship, making the ship steer.

The original meaning of the rudder: the device used to control the course of the stern. When the word "rudder" is mentioned alone, the default generally refers to the rudder, such as the rudder (rudder). With the development and progress of science and technology, "rudder (a device that controls the direction of a car when driving)" and "rudder (a rudder attached to the end of the aircraft made by applying the principle of yaw motion), or movable Auxiliary wings, used to control its horizontal movement during flight)."
