The blade (12) has a platform (14) for fixing of a rotor (4), and two aerodynamic surfaces that are arranged opposite to each other and extending from the platform according to a principal direction of the blade. The platform includes a portion forming a surface for delimitation of fluid stream and for bypassing the aerodynamic surfaces. Another portion is located under the former portion. The latter portion is able to cooperate with an interior face of a wall (18) of the rotor located around an opening of the rotor for its fixing. |
