Title
(EN) UNDERWATER PROPELLER DEVICE WITH PULSED JETS
(FR) DISPOSITIF DE PROPULSION SOUS-MARIN POURVU DE JETS PULSÉS
Abstract
(EN) The present invention refers to a device, which is autonomous or which can be associated with another structure, for propulsion in a liquid environment, which can be used in many fields, from underwater exploration to checking on and maintaining equipment to mini-invasive surgery. More precisely, the invention relates to an underwater propeller device comprising: a bladder body (1) completely made of a soft material, developing along and around a central longitudinal axis (X), defining an internal chamber (2) between a dorsal wall (11, 22) and a ventral wall (21); in said bladder body (1), an inlet opening (3) and an outlet opening (4) of a liquid in and out of said chamber (2), arranged at a longitudinal end of the body; and drive means (5, 91) for driving a contraction of said bladder, arranged on said dorsal wall and comprising a mechanical connection with said ventral (21) to cyclically attract the ventral wall to the dorsal wall, thereby causing a pulsed ejection of a propeller jet from said chamber through said outlet opening (4).
(FR) La présente invention concerne un dispositif, qui est autonome ou qui peut être associé à une autre structure, permettant une propulsion dans un environnement liquide, qui peut être utilisé dans de nombreux domaines, de l'exploration sous-marine à la vérification et à la maintenance du matériel, en passant par la chirurgie mini-invasive. Plus précisément, l'invention concerne un dispositif de propulsion sous-marin comprenant : un corps de vessie (1) complètement fait d'un matériau souple, se développant le long et autour d'un axe longitudinal central (X), définissant une chambre interne (2) entre une paroi dorsale (11, 22) et une paroi ventrale (21) ; dans ledit corps de vessie (1), une ouverture d'entrée (3) et une ouverture de sortie (4) d'un liquide dans et hors de ladite chambre (2), situées à une extrémité longitudinale du corps ; et des moyens d'entraînement (5, 91) pour entraîner une contraction de ladite vessie, situés sur ladite paroi dorsale et comprenant une liaison mécanique avec ladite paroi ventrale (21) pour attirer de manière cyclique la paroi ventrale vers la paroi dorsale, ce qui permet de provoquer une éjection pulsée d'un jet de propulsion à partir de ladite chambre à travers ladite ouverture de sortie (4).
