Abstract
(EN)
The present invention relates to a turbine (2) for location in a fluid flow. Aspects of the present invention aim to overcome the problems associated with complex marine turbines and provide a simple, robust and economic design. The blades (22) may be located downstream of the turbine body and means (8, 10, 18) are provided to enable relative rotational movement between the support (4) and the turbine such that the turbine aligns with the fluid flow and at least one bearing (28) is configured to be in contact with the fluid. There may also be a generator (34, 36) for a marine turbine comprising a rotor (34) arrangement and stator arrangement (36) wherein the generator is flooded with fluid in which the marine turbine is immersed. Additionally or alternatively, the rotor and/or the stator is provided with a matrix, layer and/or coating to provide a fluid sealing function. There may also be provided an axial load bearing assembly including a braking means (40) arranged to control rotation of the shaft.

La présente invention concerne une turbine pour l'emplacement d'un écoulement de fluide. Selon certains aspects, la présente invention a pour but de résoudre les problèmes associés aux turbines marines complexes et offre une conception simple, robuste et économique. Les ailettes peuvent être situées en aval du corps de la turbine et des moyens sont prévus pour assurer un mouvement de rotation relatif entre le support et la turbine de telle sorte que la turbine s'aligne sur l'écoulement du fluide, et qu'au moins un palier soit configuré pour être en contact avec le fluide. Des moyens de raccordement électriques peuvent également être prévus qui comprennent un premier élément de raccordement en vue de sa rotation avec la turbine et un second élément de raccordement prévu pour ne pas entrer en rotation, et être relié au câble vers un emplacement éloigné. Un support peut également être prévu pour être relié de manière fixe à la terre dans un écoulement de fluide, ledit support comprenant un organe allongé doté d'une extrémité supérieure et d'une extrémité inférieure, la partie du support adjacente à l'extrémité supérieure présentant une superficie de section transversale réduite en direction de l'extrémité inférieure. Un générateur peut également être prévu pour une turbine marine, et peut comprendre un rotor et un stator, le générateur étant rempli de fluide dans lequel la turbine marine est immergée. En outre, ou selon une variante, le rotor et/ou le stator sont pourvus d'une matrice, d'une couche et/ou d'un revêtement pour assurer une fonction d'étanchéité de fluide. Un ensemble palier de charges axiales peut aussi être utilisé et comprendre un moyen de freinage permettant de commander la rotation de l'axe.
