Title (EN) VORTEX GENERATOR AND APPLICATIONS THEREOF
(FR) GÉNÉRATEUR DE VORTEX ET UTILISATIONS DUDIT GÉNÉRATEUR DE VORTEX
Abstract:
(EN) The invention relates to a vortex generator (1) comprising a cylindrical housing (5) with a closed first end face and an open second end face; an impeller (2) with a plurality of blades (3) rotatably mounted within the cylindrical housing; drive means (4) for driving the impeller about a central axis of the cylindrical housing; whereby, in use, the rotating impeller generates a vortex with a reduced pressure core between each pair of adjacent blades so as to form a vortical attraction force that attracts the vortex generator towards a horizontal, sloping, vertical and/or inverted surface arranged adjacent the open second end face. The tip of each blade may be arranged a predetermined distance from the cylindrical housing so that, in use, the rotating impeller further generates a hypocycloidal flow with mini -vortices. The vortex generator may be used as part of a vehicle (18) to so as to attract the vehicle to a horizontal, sloping, vertical and/or inverted surface. The vehicle may further comprise means for moving the vehicle across the surface and preferably means for conducting an operation when located at a position on the surface.
(FR) L'invention concerne un générateur de vortex (1) comprenant un boîtier cylindrique (5) présentant une première face d'extrémité fermée et une seconde face d'extrémité ouverte, une roue (2) portant une pluralité de pales (3) montée rotative dans le boîtier cylindrique, et des moyens d'entraînement (4) qui entraînent la roue autour d'un axe central du boîtier cylindrique. En utilisation, la roue génère en tournant un vortex présentant un cœur à pression réduite entre chaque paire de pales adjacentes de manière à créer une force d'attraction tourbillonnaire qui attire le générateur de vortex vers une surface horizontale, inclinée, verticale et/ou inversée agencée adjacente à la seconde face d'extrémité ouverte. La pointe de chaque pale peut être agencée à une distance prédéterminée du boîtier cylindrique, de sorte qu'en utilisation, la roue génère par ailleurs en tournant un courant hypocycloïdal de mini-vortex. Le générateur de vortex peut être utilisé en tant qu'élément d'un véhicule (18) de manière à attirer le véhicule vers une surface horizontale, inclinée, verticale et/ou inversée. Le véhicule peut par ailleurs comprendre un moyen permettant de déplacer le véhicule sur toute la surface, et de préférence un moyen permettant d'effectuer une manœuvre lorsqu'il est placé en une position sur la surface.
