Title
(DE) ROTOR MIT HORIZONTALER ACHSE UND BOOT MIT DIESEM ROTOR
(EN) HORIZONTAL AXIS ROTOR AND BOAT EQUIPPED WITH SAID ROTOR
(FR) ROTOR À AXE HORIZONTAL ET BATEAU COMPRENANT LEDIT ROTOR
Abstract
(EN) It is an object of the present invention to provide a horizontal shaft rotor with low power and high rotation efficiency by achieving that a high-speed flow according to the Coanda effect caused by rotating the blade rather than pushing out the fluid with the blade flows to the back face direction and propulsive force is obtained as a reaction. A horizontal shaft rotor comprising a lift-type blade, wherein, in the lift-type blade 1, a front face 3D in a flow receiving direction is a large arcuate bulging face in a string direction, a rear face 3E in a discharge direction is made smaller than the bulge of the front face 3D, so that, when the blade rotates, a high speed flow passing along the string direction of the front face from the rear edge portion 3G to the back face 3E direction generates propulsive force.
(FR) La présente invention vise à fournir un rotor à axe horizontal dans lequel, plutôt qu'un fluide soit poussé par des pales, un écoulement à grande vitesse associé à un effet Coandă résultant de la rotation des pales s'écoule vers la face arrière et une force de propulsion est obtenue comme action contraire, de telle sorte que le rotor à axe horizontal a une grande efficacité de rotation à une faible puissance. Une pale de type à portance (1) est configurée de telle sorte que la face avant (3D) dans la direction de réception d'écoulement est une face bombée ayant la forme d'un grand arc dans la direction de corde, et que la face arrière (3E) dans la direction de libération d'écoulement est plus petite que le renflement de la face (3D), de telle sorte qu'un écoulement à grande vitesse passant depuis la partie de bord de fuite (3G) dans la direction de face arrière (3E) le long de la direction de corde de la face avant durant la rotation agit comme force de propulsion.
