Abstract

The invention relates to an oscillating propeller (1) of a two-blade (10, 11) aerogenerator, said blades being symmetrically mounted in relation to the centre of a hub (12) of a rotor. The aerogenerator is fixed at the top of a supporting mast and the bottom of the mast is anchored to the ground. The hub (12) is mounted in such a way that it rotates with the driving axle (ω) of the aerogenerator and is fixed to the driving axle (ω) in an articulated manner by means of an articulation element (123) in order to drive an electric generator. The articulation element (123) of the articulation axle (Δ) perpendicular to the driving axle (ω) forms an angle (δ) with the normal (N) to the axis (γ) of the blades (10, 11). Intercalated elements are provided between the articulation element (123) and the hub (12) in circular openings (125) formed on the lateral surface of the hub (12) according to the articulation axle (Δ).
