Definitions

  • the invention relates to a rudder for ships according to the preamble of claim 1.
  • the so-called Costa bulb or propulsion bulb serves to form, as an extension of the propeller axis in the region of the rudder blade, a curvature which is pear-shaped or zeppelin-shaped and constitutes a flow body.
  • This flow body has the purpose that the overall profile of the hub is extended so far that only a small turbulence of the outflowing water is formed.
  • Such a Costa pear is for example through the pamphlets DE 198 44 353 A1 .
  • the effect of the Costa bulb is based on its bulbous shape, with which it stands out from the rudder or rudder blade, so that there is a favorable flow guidance.
  • the Costa bulb is thus laterally opposite the rudder blade and is in the event of a shock or impact or pressure in the immediate danger area before the actual rudder blade would be at risk.
  • the object of the invention is to provide a rudder blade for ships, which is less prone to damage or destruction despite favorable flow control against external influences due to shock, impact or pressure and the flow body destroyed by the action of pressure or impact independently.
  • the flow body, the rudder blade viewed in the vertical direction, divides into two areas (A, B), wherein the two areas are identical or not identical in profile.
  • the longitudinal center lines of the areas of the rudder blade do not coincide with the center lines of the flow body and form an angle ⁇ .
  • the flow body has predetermined breaking points, which lead to the destruction of the flow body with increased force, impact, shock or pressure. It is also advantageous if the predetermined breaking points are designed as predetermined breaking lines. It is also expedient if the predetermined breaking lines are oriented in the longitudinal and / or transverse direction of the flow body. But it is also advantageous if the predetermined breaking lines are distributed like a net over the flow body.
  • the predetermined breaking points or predetermined breaking lines are designed as material weakenings, material reductions and / or score lines.
  • the flow body consists of metal or a non-metallic material or a metal-non-metal mixture.
  • the flow body consists of a carbon-fiber composite material.
  • the material comprises embedded carbon fibers, graphite fibers and / or glass fibers.
  • the flow body consists of plastic or plastics.
  • the flow body consists of POM plastic, such as polyoxymethylene, polyformaldehyde or polyacetates.
  • the flow body consists of two individual shell-shaped to the flow body complementary longitudinal bodies in the region of their longitudinal edges on predetermined breaking lines on the outer wall surfaces of the rudder blade are held, wherein the propeller facing edge regions of the two shell-shaped longitudinal body are connected via predetermined breaking lines with a spherical cap-like component which is fixed or detachably connected to the rudder blade.
  • Fig. 1 shows the tail 11 of a ship 10 with a drive propeller 12 and a rudder 13, the rudder blade 15 is provided with a pear-shaped or zeppelin-shaped flow body 20, which is preferably designed as a hollow body and which can be integrated in both the rudder blade 15 and may consist of two or more components 21, 22 which are fixed to the outer wall surfaces 15 a, 15 b of the rudder blade 15.
  • the flow body 20 may also be formed as a solid body.
  • a curvature is formed in the region of the rudder blade 1, which forms the flow body 20, also called propulsion bulb or Costa bulb.
  • the flow body 20 is designed so that it is itself destructive to pressure, impact or impact.
  • the wall 25 of the flow body 20 consists of individual wall sections 30, which are connected to one another via predetermined breaking lines 40 in the form of material weakenings or score lines (FIG. 6).
  • the predetermined breaking lines are formed running in the longitudinal direction and / or transversely to the longitudinal direction of the flow body 20 in the wall 25 of the flow body 20, wherein the Rupture lines 40 may also be irregular.
  • the predetermined breaking lines 40 can also be distributed in a network over the flow body 20.
  • frangible lines 40 are formed and mounted so that in the outer wall surface of the flow body 20 no bumps, depressions, grooves o. The like. Emerge and so the smooth outer wall surface is maintained.
  • the flow body 20 itself is destroyed or self-dissolves in the event of impact, impact or pressure. Thus, no excessive force is transmitted to the rudder blade itself, so that leading to a significant damage or destruction impairment of the rudder blade can be avoided.
  • Fig. 2 shows the view of a rudder blade 15 with a flow body 20, which is composed of three individual parts 50, 51, 55.
  • the parts 50, 51 form the sides of the flow body 20 on the sides of the rudder blade 15 and the part 55 forms the front, d. H. the propeller 12 facing substantially approximately hemispherical conclusion.
  • the arrows X, X1, X2 indicate that the parts 50, 51, 55 are disassembled from the rudder blade 15 in these directions.
  • the parts 50, 51, 55 of the flow body 20 are designed shell-shaped and preferably do not form solid bodies, but in the assembled state only a hollow body which is attached to the rudder blade 15.
  • the flow body 20 consists of two individual shell-shaped, complementary to the flow body longitudinal bodies 50, 51 which are held in the region of their longitudinal edges 50a, 51a via predetermined breaking lines 40 on the outer wall surfaces 15a, 15b of the rudder blade 15, wherein the propeller 12 facing edge portions 50a , 51 b of the two bowl-shaped Longitudinal body 50, 51 are connected via predetermined breaking lines 40 with a spherical cap-like component which is fixed or detachably connected to the rudder blade 15 ( Figures 2 and 3).
  • the rudder blade 15 is not a homogeneous component but is formed from an upper region A and from a lower region B.
  • the upper portion A has at least on its front side a curvature or orientation which is more bent or oriented to the left and the lower part B has at least one curvature or orientation which is more bent or oriented to the right.
  • this difference can be recognized by the fact that the two front areas are formed like tongues which do not coincide with each other, but are approximately Y-shaped apart.
  • the longitudinal center lines LM1 of the two areas A and B are not congruent and parallel, but have an angle ⁇ between each other. Also, the longitudinal center lines LM1 of the regions A and B are not located on the center line ML of the flow body 20.
  • the regions A and B may be different so that the longitudinal centerlines LM1 pierce the leading edge at LM1 and thus lie outside the center line ML of the flow body 20.
  • the upper region A may be identical to the lower region B, so that either the deviation of the longitudinal center line LM1 to the center line ML of the flow body 20 is equal and at zero angle or zero can.
  • FIGS. 8 and 9 each show a view of the rudder blade 15 from below or from above. Clearly visible is the angle ⁇ between each the longitudinal center line LM1 of the rudder blade 15 and the center line ML of the flow body 20.
  • Fig. 4 shows a rudder blade 15 with a flow body 20 in a side view from the left rear.
  • the areas A and B can be seen here. In the rear area, the areas A and B are identical, whereas they are designed differently in the front area (see also Fig. 2).
  • Fig. 5 shows the rudder blade 15 in a rear view and Fig. 7 is a front view. In each case, the flow body 20 can be clearly seen.
  • Fig. 6 shows the rudder blade 15 according to the invention with the flow body 20, wherein the flow body for better own destruction in a force, shock or pressure has predetermined breaking points.
  • the predetermined breaking points are advantageously provided as predetermined breaking lines 40, which are distributed over the surface of the flow body. These are advantageously oriented in the longitudinal and / or transverse direction of the flow body 20. It is particularly advantageous if the predetermined breaking points are formed by material reduction or by notching, ie by score lines.
  • the predetermined breaking lines 40 are distributed like a net over the surface of the flow body 20.
  • the rudder blade 15 has a cross-sectional area 16, the longitudinal center line LM1 is offset at an angle ⁇ to the center line ML of the flow body 20, so that the nose bar 70 of the rudder blade 15 facing the drive propeller 12 outside the center line ML of Flow body 20 comes to rest.
  • the flow body 20 is advantageously made of metal. In another embodiment, however, it may also be formed from a non-metallic material, such as a carbon-fiber composite, preferably with embedded carbon fibers, graphite fibers and / or glass fibers. Also, a metal-non-metal mixture may be predetermined.
  • a non-metallic material such as a carbon-fiber composite, preferably with embedded carbon fibers, graphite fibers and / or glass fibers.
  • a metal-non-metal mixture may be predetermined.
  • the flow body 20 may also be made of plastic or plastics.
  • POM plastics can be used, such as polyoxymethylene, polyformaldehyde or polyacetates. These substances typically have a high lubricity, which is advantageous for the friction in the water.
