CA 2335929

The invention concerns a device in the form of a spiral cylindrical cavity, mobile or fixed, capable of being adapted to the tip of all carrier profiles, in particular to aeroplanes and gliders or craft requiring lifting capacity in its displacement, for reducing induced drag, increasing thrust and reaching in flight or lift, low speed levels with wide angles of incidence and high speed levels in cruising degree. The invention enables to use for similar performances or for initial performances weaker traction systems for longer and faster flights using less fuel and/or using larger loads. Moreover, said device enables to considerably and artificially increase a wing extension while preserving the same profile and the initial aerodynamics of an aeroplane in flight or of a levitating craft using lifting capacity up to subsonic speed.

La présente invention concerne un dispositif en forme de qualité cylindrique en spirale, mobile ou pas, pouvant s'adapter à l'extrémité de tous profils porteurs, en particulier aux avions et aux planeurs ou pour appareils demandant une portance accrue dans son déplacement, permettant de réduire la traînée induite, d'augmenter la poussée et d'atteindre en vol ou en sustentation, de basses vitesses aux grands angles d'incidence et de grandes vitesses en palier croisière. Le résultat de cette invention permet d'utiliser, aux mêmes performances ou aux performances initiales, de plus faibles motorisations, de faire des trajets plus longs et plus vite tout en consommant moins de carburant et, ou d'utiliser des charges plus importantes. En outre, ce dispositif permet d'augmenter considérablement et artificiellement l'allongement d'une aile tout en conservant son même profil et l'aérodynamique initiale d'un avion en vol ou d'un appareil en sustentation utilisant la portance jusqu'à la vitesse subsonique.
