| 摘要 |
The invention relates to a rotor (1) comprising blades (2, 3) rotating about an axis of rotation (X), each blade being configured such as to transmit to the axis of rotation, during one rotation of the rotor about the axis of rotation, when exposed to the flow of a fluid, a driving torque driving the rotation of the rotor and a load torque which tends to oppose the rotation of the rotor, alternately, each blade comprising in a region of an outer longitudinal edge of the blade a flexible portion (21, 31) configured such as to retract towards the inside of the rotor when the blade transmits the load torque to the axis of rotation of the rotor, and to move into an extended position towards the outside of the rotor, during the half-rotation of the rotor according to a maximum retraction position, when the blade transmits the driving torque to the axis of rotation of the rotor, the flexible portion being driven only when exposed to the flow of the fluid. |
