Definitions

  • Anti-roll stabilizers for ships with folding fins or not currently known are equipped with fins of which structure can be simple (single fin) or complex (curvature flaps hinged on a main fin simple).
  • the force perpendicular to the plane of the fin which produces the stabilizing effect is characterized by a coefficient commonly known as Cz.
  • the Cz coefficient varies according to fig. 2 depending on the inclination fin in the water streams.
  • the Zo part of the curve corresponds to the corresponding drop zone loss of lift.
  • the surface of the fin will be all the smaller as the Cz will be high.
  • the surfaces of the fins determine the weights and therefore stabilizer prices.
  • they determine what is called the loss of additional buoyancy, i.e. water volumes contained in the hull housings in which are folded the fins in good weather.
  • the flap is articulated on the main fin by all known mechanisms (pinions, connecting rods, etc.).
  • the Cz is improved but the installation is complex and expensive continuously articulate in seawater.
  • This articulation can in certain cases constitute a limit on the surface of the aileron, because the deformations of the aileron during operation due to bending may be incompatible with this joint.
  • resistance to the advancement is high and can present as the profile in "fish" a characteristic of abrupt withdrawal. A example of this type of profile is given in fig. 5.
  • the invention has the effect of increasing the Cz to a value substantially greater than that of a curved flap profile, while maintaining a simple structure and resistance to advancement less than or at most equal to that of a profile in "fish" or curvature flap and this whatever the average wingspan / rope ratio.
  • the stabilization device consists of a main fin with which is associated a or several pairs of fixed and medium camber flaps.
  • the profile of the fin presents a relatively flat drop characteristic which allows to easily absorb disturbances in the direction of the water streams due to the residual movement of the ship and at the orbital speed of the swell. Examples of this type of profile are given in figs. 6, 7, 9 and 10 which make appear shutters of known general shape.
  • main fin 1 (fig. 6) of known conventional symmetrical profile with which are associated one or more pairs of flaps 2 a and 2 b with fixed arched profiles relative to the main fin and located near the trailing edge F of the main fin, respectively on the lower side 1 a and upper side 1 b of the main fin, the camber of the flaps being opposite and symmetrical.
  • FIGS. 6 and 6a an example of a profile comprising a single pair of flaps 2 a , 2 b is described in FIGS. 6 and 6a.
  • the flaps 2 a and 2 b are arranged so that the tangents to the leading edge Ta and Tb at their mean profile Pa and Pb are parallel to the mean plane of the main fin, but other arrangements such as oblique tangents can be considered.
  • the camber Pa, Pb of the flaps, their distance Xv, Ya, Yb to the main fin and their Cv rope can be adjusted by depending on the speed characteristics of the profile in the ambient environment, of the average immersion of the profile in this environment and acceptable resistance to advancement or predictable.
  • the main fin and the flaps can also consist of known conventional profiles or not, symmetrical or not.
  • the shutters can be without medium camber.
  • the main fin 1 is equipped at its end (opposite side to the vessel N) with a plate 3 which limits the circulation of the ambient fluid between the lower surface 1 a and the upper surface 1 b .
  • the shutters 2 a and 2 b are connected fig. 7 to the main fin 1, on the one hand, by the plates 3 and 4 at the end of the main fin and, on the other hand, by spacers 5 a , 5 b , 5 c ... 5 f arranged on along profiles 1, 2 a and 2 b .
  • This connection can be made by any known means (welding, bolting, ).
  • the spacers 5 a , 5 b , 5 c .. may not exist.
  • An axis 6 keyed to the main wing 1 rotates the main fin 1 with his or her flaps 2 pairs and 2b and the plates 3 and 4. This assembly is equivalent to a single fin.
  • the wing with fixed shutters described can be used to all the steering and stabilization devices ship movements and generally for any surface and any foldable set or not and this whatever the ratio of wingspan to average chord of the fin. So the fin suitable for any passive system or assembly ( stabilization of rudder, drift, etc.) or active or semi-active and whether it is foldable or not.
