Definitions

  • the invention relates to a rudder arrangement for ships at higher speeds with a cavitation-reducing, twisted, in particular full-swarm wind according to the preamble of claim 1.
  • Ship rudders such as full-rudder or balance rudder, with or without hinged fin are known in various embodiments. Also known are ship's rudder with a twisted rudder blade, which consists of two superimposed rudder blade sections, the propeller facing nose strips are offset laterally such that one leading edge to port and the other nose strip is offset to starboard.
  • a rudder arrangement of the generic type is known from EP 1 857 358 A2 or the DE 20 2004 021 500 known.
  • the GB 332,082 also discloses a ship's rudder with a twisted rudder blade, its profiled areas facing the propeller, namely the nose-ledges, facing starboard and to port side are, the nose strips are formed pointed tapered.
  • the cross-sectional profiles of the two rudder blade sections are designed so that the port side and starboard side side wall surfaces of the two rudder blade sections between the end strips to the laterally bent nose strips völbungslos straight indeed, so that the side wall surfaces have no outwardly curved areas with different radii of curvature.
  • the profile design of the rudder blade is such that the two cross-sectional areas of the two superimposed rudder blade sections are the same size and extend over the entire height of the rudder blade. Sharp-edged notches are formed by the tapered leading edge strips, which are exposed to cavitation and destruction. With the profile design of this rudder an improvement of the propulsion is to be achieved.
  • the generated on the rudder blade in the lower region, generated by the very high flow velocities Propellerabstrom forces are collected and the rudder blade are balanced, without causing damage to the bearings for the rudder stock.
  • the rudder arrangement according to the invention is designed in the manner that the cross-sectional surface portions of the upper rudder blade portion and the lower rudder blade portion in the region between the end bar and the largest profile thickness of the rudder blade have a length which is at least 1 1/2 times the length of the cross-sectional surface portions of the upper rudder blade portion and the lower rudder blade portion between the largest profile thickness of the Rudder blade and the leading edge correspond that the upper rudder blade portion port side and the lower rudder blade portion each extend a flat arcuate and extending from the nose strips towards the end strip side wall portion having a length extending over the length of the side wall portions of the nose strips to the largest profile thickness plus a length which corresponds at least to 1 ⁇ 3 the length, wherein adjoining the flat arcuate side wall portion of the rectilinear side wall portion which terminates in the end bar, and that the upper rudder blade portion starboard side and the lower rudder blade portion each port a strongly curved, arcuate and extending
  • the lower rudder blade section is given a narrow profile by the inventive design of the twisted rudder blade as Vollschweberuder with its low profile thickness and the storage of the rudder stock in the region of the largest profile thickness in the upper rudder blade section of the rudder blade, so that despite the high speeds of balancing the rudder blade, even if this has the largest dimensions, is possible, which can only be achieved by the functional interaction of twisted rudder blade with the rudder blade bearing, but this can not be achieved with other rudder blade configurations and rudder stock bearings on the rudder blade impacting.
  • a rudder assembly ie a system of two components is created, namely a twisted rudder blade and a functionally cooperating with this, specially mounted rudder stock.
  • This rudder arrangement is the surprisingly found technical solution to build large and largest full-swede blades.

Only a slim rudder profile, so a low profile thickness, even allows the construction of energy efficient rudder blades, because the thicker a rudder profile, the more resistance it generates in the accelerated flow of the propeller water.
  • Another advantage of the rudder arrangement of the combination of the twisted rudder blade with the bearing of the rudder stock is the use of higher quality materials.

  • Such difficult mechanical constructions can hardly be twisted at the front edge, since the fixed rudder horn and the rotating rudder blade are not so freely formable.
  • the rudder blade internal forces and moments occurring in such Halbschwebetudern are much larger than Vollschweberudern with the storage of the rudder stock according to the invention.
  • a significant twisting of the propeller-facing front edge of the rudder blade would mean significant constructive uneconomic measures, namely with correspondingly thicker profiles.

  • the rudder stock also with a forging as a hub, is connected to the rudder near the hydrodynamic center, whereby only a small load is achieved by bending moments. Overlapping vibrations can be excluded by this design.
  • this has the profile according to the invention, which is divided into an upper and lower half, the leading edge or leading edges are vertwistet at certain angles.
  • the propellor wake flow and the angle of this to the midship line dictates how many degrees the profile leading edge is twisted.
  • the propeller vortex flow flows better along the rudder blade, and there are no pressure peaks on the tread surface of the rudder blade, which favor cavitation.
  • the improved flow around the rudder results in significant fuel savings and improved maneuverability.
