Canyousea | La Turbovoile®

  • rotors Flettner appliquant l’effet Magnus. Un phénomène physique décrit par le physicien Heinrich Gustav Magnus qui explique la trajectoire courbe — d’une balle de tennis liftée ou d’un ballon (bien tiré) lors d’un coup-franc au football — d’un objet en rotation.

    De quoi s’agit-il ? En tournant, l’objet en rotation (balle ou cylindre) va modifier par son frottement la vitesse du courant d’air qu’il traverse : d’un côté, l’air sera accéléré donc la pression va diminuer ; côté opposé, l’écoulement de l’air est freiné et la pression augmente. Résultat : une différence de pression qui crée une force variable selon la vitesse de rotation, et dirigée de la faible pression vers la haute.

  • la portance, créée par le passage d’une aile d’avion ou d’une voile de bateau dans un flux d’air. Mais, de la même manière qu’un rotor d’hélicoptère en rotation donne une portance forte à des pales de surface réduite, un mât cylindrique tournant délivre beaucoup plus de portance qu’un mât-aile même prolongé d’une voile. D’où l’idée des rotors Flettner.
