Definitions

  • the present invention relates to rudders in general: stabilization rudders for surface ships, steering rudders, and diving rudders for submarines. In all cases, these are fins which can be oriented from the ship by means of a drill bit.
  • the rudders are made entirely of metal. They comprise a mechanically welded framework on which the hydrodynamic envelope is mounted, obtained by welding sheets previously formed in the hot state.
  • the interface with the drill bit is a massive part produced by molding, the surfaces of which are machined.
  • the steel drill bit is forged and then machined.
  • the patent GA A 2231853 is limited to the description of a method of manufacturing rudders whose principle is based on the molding and the assembly of two halves of rudders, each half resulting from the molding of a half-fin and a half-wick, this in order to obtain a one-piece wick rudder and fin.
  • This molding manufacturing process which also has the disadvantage of being difficult to implement, also gives a wick rigidly linked to the fin, therefore not removable.
  • An object of the invention is to overcome these drawbacks, that is to reduce the mass of such rudders substantially and to make their manufacture less workable by eliminating hot forming, by the use of composite materials.
  • Another important object of the invention is the almost exclusive use of composite materials for the production of these rudders, both at the fin and the wick and at the connection interface between the two, in particular to avoid metal-composite structural associations which are never without drawbacks.
  • the solution provided consists in providing in the structure of the fin a box for receiving the lower part of the wick, their sections being polygonal, for example hexagonal, to ensure between them a rotation lock.
  • Said receiving box of the lower part of the wick is joined by all of at least one of its lateral faces to the rest of the structure of the fin. It is advantageously made of glass-resin composite.
  • the structure of the fin comprises an assembly of separate boxes of which said box receives the lower part of the wick.
  • the filament winding technique is carried out by association of the filament winding technique and the draping technique.
  • the first makes it possible to give an oblique orientation of the reinforcing fibers - for example at + 45 ° and at -45 ° - relative to the longitudinal axis of the wick, and the second an orientation at 0 °.
  • They are preferably carbon fibers.
  • the rudders In addition to the drill bit and the fin, the rudders have a spur, which is subjected to significant shear forces. Therefore, it is advantageously produced in the general form of a full cylinder made up of rods of pultruded glass-resin composite, compacted and bonded with resin.
  • a steering rudder is shown in place on a ship of which only the bottom F and the butt C appear very schematically. It is a rudder of the type with compensation for the fact that at the bottom of the fin 1 part of it is on the other side of the axis of rotation XX relative to its main part. Fin 1 is suspended and articulated by through a wick 2 and a spur 3, both focused on XX.
  • rudder namely fin 1, wick 2 and spur 3
  • the only metal parts are two connecting inserts allowing conventional fixing methods and rings attached to the drill bit 2 at the P bearings.
  • the wick is connected to the fin via a hub. It is generally engaged in the hub by conical fitting, the latter being welded to the frame of the fin. This connection system is simple and does not lead to any particular technical difficulties.
  • the solution found consists of a tubular box 4 secured to the rest of the structure of the fin 1, of polygonal section, and preferably hexagonal as in the drawing, FIG. 3, admitting the lower part of the drill bit 2 of corresponding section. Locking in rotation is therefore ensured by the shape of the sections, and perfect by adding a setting resin in 5.
  • a metal ring 6, Figs. 2 and 3 is glued to the inside of the box 4, and an end piece 7 at the lower end of the wick 2, the end piece 7 and the ring 6 being secured to each other by keying.
  • the box 4 is advantageously made of glass-resin composite. As can be seen in Fig. 1, it extends clearly beyond the lower end of the wick 2, in fact up to the appendix Ca of the butt C in which the diverter pivots 3. To allow the establishment of the latter at the mounting the rudder on the ship, the box 4 has a side hatch 8, and is open at its lower end, therefore having in fact a tubular shape.
  • the fact of extending the box 4 as much as possible has the advantage of having an area which is all the more important for its junction with the rest of the structure of the fin 1. In a preferred embodiment, this junction is made by gluing over the entire extent of a lateral face of the box 4. In a rudder of different shape such as a stabilizing rudder in particular, where the box 4 occupies an intermediate position in the structure of the fin, there is well heard from two opposite lateral faces of the box 4 for the junction with the rest of said structure.
  • the wick 2 has also been the subject of special research, as to the problem of its resistance as a function of the torques and the very large bending forces to which it is subjected, and as to the best way to achieve it.
  • a hollow wick 2 obtained by combining two techniques for using composite materials: filament winding and draping, and using a mandrel whose section evolves. gradually, in an intermediate zone, from the circular shape to the polygonal shape.
  • filament winding and draping the choice was made on carbon fibers, which are cheaper than more efficient aramid or boron fibers, oriented obliquely, for example at + and -45 ° by filament winding, and longitudinally at 0 °. by draping, the winding and draping operations are preferably alternated.
  • the drill bit 2 is finalized by bonding the end piece 7 in its lower end and rings 9 for rotation in the bearings P.
  • the spur 3 is essentially, but highly stressed in shear, which has led to design it in the form of a solid cylinder, with fibers oriented longitudinally.
  • a simple and economical way to manufacture it consists of compacting rods or rods in glass-pultruded resin composite, in a resin with high mechanical characteristics. An envelope is then produced by draping to obtain its final shape.
  • the spur 3 engages in a cylindrical cavity 10 formed in the body of the fin 1, FIG. 4.
  • a metal connection is provided to fix it to the fin, that is to say an end piece 11 glued to its lower end, keyed into a ring 12 inserted in the body of the fin 1.
  • This connection is visible in Figs. 4, 5.
  • the ring 12 has been given a square external shape in order to obtain good immobilization in the body of the fin 1 which may be syntactic foam in this area.
  • the fin 1 may essentially consist of an envelope made of sandwich type materials with a honeycomb core, or else of a machined honeycomb block covered with a composite envelope. glass-resin, or two half-shells that have just been bonded to a network of monolithic stiffeners, the filling material being syntactic foam, or even an assembly of glass-resin composite parts with also syntactic foam filling.
  • the fin 1 comprises, in addition to the box 4 serving for the connection with the wick 2, a plurality of boxes glued together, and the whole of which has a shape close to its final shape.
  • These boxes are arranged in such a way that the glue interfaces are stressed in shear.
  • These are advantageously machined foam blocks covered with a glass-resin composite envelope.
  • the foam used is for example a high density foam based on polyvinyl chloride.
  • the rudder comprises two superimposed upper boxes 13 and 14, glued by one of their sides to the assembly of a side face of the box 4 receiving the wick 2, FIG. 7, an intermediate box 15 glued under the box 14 and three juxtaposed lower boxes 16 to 18, two of which, 16 and 17, are glued by their upper face below the intermediate box 15.
  • the number and the arrangement of the boxes are determined based on the shape of the fin and how it is stressed.
  • the assembled boxes are then introduced into a mold where they are coated with a foam identified in 19, advantageously syntactic foam, covered with an envelope 20 of glass-resin composite.
  • This design of the fin 1 makes it possible to obtain excellent continuity in the structure and has the other advantage of using only simple and well mastered manufacturing techniques.
  • the invention which has just been described is directly applicable to the production of stabilizing rudders.
  • rudders for submarines it requires a simple adaptation when the choice of materials for the fin - more especially the foams - according to their characteristics of resistance to pressure.
  • the invention is of great interest in that it provides a very substantial weight gain, since it is greater than 70%, compared to current metal versions.
  • the gain is also real from the point of view of manufacturing cost, and especially from the point of view of maintenance, due to the virtual disappearance of metal parts, and consequently the risks of corrosion.
