  • the power requirements are minimized in the invention by providing the pivoting or sliding arrangement so that the thrust wing centre of pressure can be maintained close to the main axis.

Abstract

L'invention concerne un ensemble de voile comprenant au moins une aile de poussée (1) rigide montée en rotation libre autour d'un axe vertical (8). L'ensemble comprend des moyens (11) de rotation ou de translation d'au moins une partie de l'aile de poussée de façon à régler la position du centre instantané de pression (9) de l'aile de poussée par rapport à l'axe vertical. L'aile de pousée est équilibrée par une aube auxiliaire (7) dans la direction du vent, pouvant pivoter librement dans la direction du vent de son centre de pression, l'angle d'attaque de l'aube auxiliaire étant réglé par la position d'un aileron aérodynamique (15) secondaire placé sous le vent par rapport à l'aube auxiliaire.

Claims (9)

  1. Dispositif de voilure comprenant au moins une aile de poussée (1) montée sur un axe vertical (4) et réglée par un volet auxiliaire (7) monté en amont de l'aile de poussée, caractérisé en ce que l'aile de poussée peut tourner librement autour de l'axe vertical, en ce que le dispositif comprend des moyens (11) servant à déplacer l'aile de poussée pour établir une distance prédéterminée entre le centre de pression instantané de l'aile de poussée et son axe de rotation vertical et en ce que le volet auxiliaire est réglé à son tour par un volet de commande secondaire (15) monté en aval du volet auxiliaire dans les limites d'un cercle de rotation défini par l'aile de poussée et par le volet auxiliaire.
  2. Dispositif de voilure selon la revendication 1, dans lequel, au niveau de sa base, l'aile de poussée est articulée pour pivoter autour d'un axe (10) à peu près horizontal pour permettre de faire pivoter le bord d'attaque de l'aile de poussée vers l'avant.
  3. Dispositif de voilure selon une quelconque des revendications précédentes, dans lequel l'aile de poussée peut pivoter vers l'avant jusqu'à une position couchée.
  4. Dispositif de voilure selon une quelconque des revendications précédentes, comprenant en outre une masse d'équilibrage équipée de moyens pour la repousser vers l'aval lorsque l'aile de poussée est déplacée vers l'amont.
  5. Dispositif de voilure selon la revendication 1 ou la revendication 4, dans lequel le volet secondaire est monté sur une poutre s'étendant en aval du volet auxiliaire.
  6. Dispositif de voilure selon la revendication 1 ou la revendication 4, dans lequel le volet secondaire est monté au bord de fuite du volet auxiliaire.
  7. Dispositif de voilure selon la revendication 1 ou la revendication 6, dans lequel le volet secondaire est monté sur une poutre qui s'étend en aval du volet auxiliaire.
  8. Dispositif de voilure selon la revendication 1 ou la revendication 6, dans lequel le volet secondaire est monté au bord de fuite du volet auxiliaire.
  9. Engin marin comprenant un dispositif de voilure selon une quelconque des revendications précédentes.
