The profile has a curvature along a blade longitudinal axis that has an aerodynamic profile that can be varied as a function of blade radius. The curvature variation is produced by elastically deforming the rear edge of the rotor. Alternatively, other mechanisms may be used, such as rear edge flaps or elastic deformation of selected profile areas. The curvature variation is preferably coupled to the overall rotation or an inclination mechanism.
