Problems solved by technology

But such auxiliary systems only contribute to maneuver prediction taking into account the current maneuvering characteristics of the ship and the surrounding environment taking into account (external) disturbances to support maneuvering and should provide decision support to the crew to control the ship
Monitoring of the mechanical integrity of the rudder is not proposed in this auxiliary system

Embodiment Construction

[0038] figure 1 A rudder 2 is shown with a rudder blade 22 which is connected to the hull 1 via a rudder stock 21 and is rotatable about an axis of rotation D for adjusting the rudder 2 along which axis of rotation the rudder stock 21 extends. On the hull 1 is provided a cylindrical tube-shaped casing 20 protruding vertically downward from the hull 1 , which extends into a groove inside the rudder blade 22 in which the rudder stock 21 is housed. The interior of the blade and—in a known manner—serve to place the rudder blade 22 on the hull 1 .

[0039] exist figure 1 In the embodiment shown in , the fin 220 is hinged on the rear edge of the rudder blade 22 (viewed in the forward direction of the ship) in a pivotable manner about the second axis of rotation D2 and is arranged via a fin bearing 225 on the On the rudder blade 22. The fin 220 is connected to the trunk 20 via a coupling device 226, so that when the rudder blade 22 rotates, the fin 220 is automatically tilted rela...

Abstract

The invention relates to a rudder for a ship having a rudder blade which can be arranged rotatably on the hull of a ship about an axis of rotation and a rudder stock for applying a torque to the rudder blade . Here, the rudder monitoring device (3) is provided with at least one sensor ( 33) and at least one arithmetic unit (31) arranged on the rudder blade (22) connected to at least one sensor (33) for evaluating and / or transmitting the measurement signal received by the at least one sensor (33) . In this way, a rudder is provided for the ship, by means of which the readiness and readiness of the rudder can be monitored in a simple manner during operation of the ship and under any desired circumstances, that is to say also for example on high seas. its mechanical integrity.

Description

technical field [0001] The invention relates to a rudder for a ship, which has a rudder blade arranged on the hull in a rotatable manner about an axis of rotation, and a rudder stock for applying a torque to the on the rudder blade. Background technique [0002] A rudder of the type usually provided on the stern of a ship and used to control and steer the ship has a rudder blade which can be arranged rotatably on the hull about an axis of rotation; and for applying torque to the rudder blade on the rudder stock. In this case, the rudder stock serves to connect the rudder blade to the hull and is rotatable in order to rotate the rudder blade about the axis of rotation and adjust the rudder in this way. [0003] The rudder of a ship is subjected to high loads during operation, that is to say while the ship is running, which stress the rudder blades and the rudder stock as well as the bearings and linkages in the form of lateral rudder forces, longitudinal rudder forces and v...
