Abstract[English]
The present invention refers to a bubble generation assembly (100) mounted on a bow (106) of a vessel (102) to generate a bubble layer along a hull (116) of the vessel (102) to reduce hydrodynamic drag. The assembly (100) includes a base plate (104) and a central fin (108) extending orthogonally from the base plate (104) along a central line (110) of the vessel (102). Further, the assembly (100) includes a plurality of secondary fins (112) extending orthogonally from the base plate (104) and oriented angularly to the central fin on either side of the central fin (108). Fluid striking the central fin (108) and the plurality of secondary fins (112) when the vessel (102) moves, generates bubbles in the fluid.[French]
La présente invention concerne un ensemble de production de bulles (100) monté sur une proue (106) d'un navire (102) pour générer une couche de bulles le long d'une coque (116) du navire (102) pour réduire la traînée hydrodynamique. L'ensemble (100) comprend une plaque de base (104) et une ailette centrale (108) s'étendant orthogonalement depuis la plaque de base (104) le long d'une ligne centrale (110) du navire (102). En outre, l'ensemble (100) comporte une pluralité d'ailettes secondaires (112) s'étendant perpendiculairement depuis la plaque de base (104) et orientées angulairement vers l'ailette centrale de part et d'autre de l'ailette centrale (108). Du fluide frappe l'ailette centrale (108) et la pluralité d'ailettes secondaires (112) lorsque le navire (102) se déplace, ce qui génère des bulles dans le fluide.
