Abstract:
A blade (20) of a rotor (5), the blade (20) having a suction side (21) and a pressure side (22) extending transversely from a leading edge (23) towards a trailing edge (24) and extending spanwise from a root section (31) towards a free end section (41). The blade (40) comprises, going from the root section (31) towards said free end section (41): a root zone (30); followed by rounded zone (35); said rounded zone (35) presenting rounded pressure and suction sides (22″, 21″) departing from said main plane (P1) in a direction (Z) parallel to the axis of rotation (AXROT) of said blade.
