A rotor blade (1) having a warping angle (α) variable in a predefined manner from its base to its end is described, the said blade being formed by means of joining together a nose piece (2) and a tail piece (3) designed to form, when joined together, a given aerodynamic profile with cross sections having predefined shapes, in which the said tail piece (3) is hollow and has substantially a shape terminating in an open "V", the free ends (3m, 3n) of the sides of which are designed to be joined to the end part (2t) of the said nose piece (2).
