  • each disc 2 is improved by making each skin 6, 7 with a stack of several folds 60, 70, each fold consisting of series of radiating sectors 61 (fig. 2) of angles for example substantially equal to 20 degrees.
  • Each radiating sector 61 is placed side by side with partial overlap of the neighboring area immediately adjacent during a "draping" operation after being at pre cut according to a specific template.
  • the different sectors are identically cut to keep the orientation of the also identical fibers.
  • a vacuum is then created under the plastic sheet so as to compaction of the part while eliminating air bubbles and the excess resin which is absorbed by a pumping cloth.
  • the entire stack then undergoes a conventional cycle of autoclave polymerization with several overpressure stages associated with temperature cycles adapted to the materials used artwork.
  • the stiffness of the wheel centrifugal ventilation can be improved by making each skin internal 6A, 6B decreasing in thickness in external radial direction towards the peripheral zone of each disc 2.
  • the skin external 7A, 7B may be of substantially constant thickness.
  • the internal skins 6A, 6B and external skins 7A, 7B can be of either constant or variable thickness. In this last case they can be for example of decreasing thickness radially, and this, either on the internal faces, or on the faces external, or even simultaneously on both sides.

  • the fret interior 21A on the contrary, preferably extends in a plane situated in front of the 2A disk extension plan.
  • the frets internal 21A, 21B and peripheral 20A and 20B are maintained in placed at least in part by the prepreg folds 60, 70 (Fig. 11 to 13) forming each internal and external skin, respectively 6A, 6B on the one hand and 7A, 7B on the other.
  • the inner hoop 21A is surrounded at least partially, for example at the level of its two lateral faces 22 and at its lower face 23, by the different folds 60, 70 of the inner skin 6A and the outer skin 7A.
  • Such a provision obviously has for advantage of ensuring better overall hold by improving the resistance to centrifugal forces and considerably limiting the shear due to centrifugal forces between the skins 6, 7 and the sandwich material 5.
  • FIGs 11, 12 and 13 illustrate in more detail the structure of the stack of folds 60, 70 constituting each skin 6, 7 as well as the how the frets 20 and 21 are held in place by said folds.

  • the peripheral hoop 20B is covered, at the less on its side faces by at least one and preferably several plies of prepregs 60, 70 respectively from the skins internal 6B and external 7B.
  • some plies of prepregs 60, and / or 70 can be folded over level of their terminal ends 61, 71 under the inner face of the peripheral hoop 20B.
  • a partial external reinforcement can be attached or glued against the outer face of the hoop device 20B.
  • FIG. 13 illustrates the production of the skins 6B, 7B at the level of the inner fret 21B.

  • Figure 7 the mold 46 and the counter mold 47 have been illustrated in the demolding position for show the dawn that has just been molded there.
  • the blades 3 will have a cross section substantially in H so as to facilitate the mounting of protections on the vacuum face or the face in pressure of the two faces of the core 3a of each blade 3.
  • the mounting protections may indeed be particularly appropriate when the ventilation wheel is intended to be used in conditions or particularly abrasive or aggressive processes for materials composing the vanes 3. Such conditions are met by example in mechanical vapor compression due to the presence of water particles in the vapor.
  • the blades 3 may be of constant width or not. In the latter case, the discs 2 will be of substantially frustoconical shape.
  • Figures 8 and 9 show how the blades 3 are provided with metal protections, preferably stainless steel.
