<p>A blade (2) for a device for generating energy from a fluid, comprising a driving surface (3) inside which a fluid is intended to flow in order to rotate the blade (2) about a rotational axis X0 which defines with axes Y0, Z0 an orthogonal reference frame X0, Y0, Z0, said blade being bounded by a leading edge (4) and a trailing edge (5), narrowing between the leading edge (4) and the trailing edge (5), running along a neutral fibre (10), where the projection of the neutral fibre (10) onto the plane X0, Y0 has a first curvature, the plane X0, Y0 being defined so as to contain the neutral fibre (10) at the leading edge (4). Application in particular to wind generators.</p> |
