Abstract[English]
A low-noise rotor for centrifugal/axial fans, vertical wind turbines and hydromachines is disclosed. The rotor comprises at least two blades fixed around a central shaft (1) by fastening elements (4). Each blade incorporates a first helical plate formed from a concave -convex (2) rotation surface and a second helical plate formed from a convex-concave (3) rotation surface. The convex-concave (3) plates of the blades, the radii of rotation of the points of the surfaces of which in the planes perpendicular to the axis of rotation of the rotor are larger than the radii of rotation of the points of the surfaces of the concave -convex (2) plates, are placed more distant from the rotor's axis of rotation than the concave -convex (2) plates, which reduces turbulence, noise and vibration while improving flow efficiency.[French]
L'invention concerne un rotor à faible bruit destiné à des ventilateurs centrifuges/axiaux, des éoliennes verticales et des machines hydrauliques. Le rotor comprend au moins deux pales fixées autour d'un arbre central (1) par des éléments de fixation (4). Chaque pale comprend une première plaque hélicoïdale formée à partir d'une surface de rotation concave-convexe (2) et une seconde plaque hélicoïdale formée à partir d'une surface de rotation convexe-concave (3). Les plaques convexes-concaves (3) des pales, dont les rayons de rotation des points des surfaces dans les plans perpendiculaires à l'axe de rotation du rotor sont supérieurs aux rayons de rotation des points des surfaces des plaques concaves-convexes (2), sont plus éloignées de l'axe de rotation du rotor que les plaques concaves-convexes (2), ce qui réduit les turbulences, le bruit et les vibrations tout en améliorant l'efficacité du flux.
