| 摘要 |
The invention relates to a turbine comprising self-orientating blades. The invention consists of a support base (1), a main rotation axle (2) which is disposed perpendicular to the direction of incidence of the fluid and which rotates in relation to the base and a plurality of secondary axles (4-4') which are disposed at the intersection between at least one first axial plane of the main rotation axle (2) and a plurality of second planes which are perpendicular to the main rotation axle (2). According to the invention, each secondary axle (4-4') is divided into two axle shafts which are equipped with at least one blade (5-6, 5'-6') having a surface that is essentially perpendicular to the direction of incidence of the fluid. Moreover, the blade (5-5') of one of the axle shafts is moved 90° in relation to the blade (6-6') of the other axle shaft. The distance separating the second axial planes from the main rotation axle (2) is smaller than the width of the blades (5-6, 5'-6') and the secondary axles (4-4') rotate freely in relation to the main rotation axle (2).
