Problems solved by technology

[0005] The dimensioning of the guide head can also lead to increased forces and loads on the rudder blade, so that the rudder blade must have an increased cross-section for reasons of stability and accordingly the guide head must also be appropriately oversized, This in turn increases the flow resistance of highly loaded rudders in an undesired manner

Embodiment Construction

[0018] A schematic diagram of the basic structure of the high-load rudder 100 is clearly shown by FIGS. 1 and 2 . This highly loaded rudder 100 has a rudder blade 10 which is fixedly connected to a rudder stock 11 . The rudder stock 11 is rotatably mounted in a rudder barrel 12 or in a rudder bearing hollow post. Wherein the rudder stock tube 12 is fixedly connected with the hull 13 . The rudder blade 10 is actuated in a known manner by a steering gear not shown here for the sake of simplicity.

[0019] In addition, a guide head 14 is provided which is fixedly connected to the hull 13, the lower edge 15 or a lower surface of which, viewed in the vertical direction, extends downwards so far that this lower edge 15 extends as far as a drive propeller of the boat with a diameter D 17 in the propeller wake 16 .

[0020] And the rudder bearing 18 in the rudder tube of a following of the rudder stock 11 carries out reinforced design, as the reinforcing part 19 shown here.

Abstract

It is proposed in order to create a high load balanced rudder ( 100 ) with a rudder blade ( 10 ), whereby the rudder blade ( 10 ) is rotatable over a rudder post ( 11 ) and the rudder post ( 11 ) is placed in a rudder port ( 12 ) and the rudder port ( 12 ) is supported over a fixed leading head ( 14 ) on a hull ( 13 ) of the ship which has a reduced flow resistance that a lower edge ( 15 ) of the leading head ( 14 ) is placed in a diameter area of a driving propeller ( 17 ) and a lower rudder port bearing ( 18 ) is configured reinforced ( 19 ).

Description

technical field [0001] The invention relates to a highly loaded rudder (Hochlast-Schweberuder) for ships with a rudder blade, wherein the rudder blade is rotatable via a rudder stock and the rudder stock is arranged in a rudder barrel, the The rudder stock is supported on the hull by a fixed steering head. Background technique [0002] Use the rudder to steer the boat in the desired direction. In this regard, semi-slung rudders, partial slack rudders and full slack rudders are well known to shipbuilding professional technicians or naval architects. In this case, the rudder blade is fixedly connected to a rudder stock, which protrudes into the interior of the hull and is rotated in a known manner with the aid of a steering gear in order to give the rudder blade a desired adjustment angle relative to the hull. The rudder blade is therefore usually arranged under the hull in such a way that it is struck by the propeller wake of the propeller in order to drive the hull. [00...
