<p>The blade (1) has a fitting (2) for fastening to a hub, and an aerodynamic element (10) comprising a main spar (20) extending span-wise from an attachment zone to a distal zone. A centrifugal force transmission element (40) has a bushing (31), and the fitting has an annular recess (200) defining recesses (201, 202) separated by top and bottom separators (211, 212) obstructing the annular recess. Rings (71, 72) are reversibly arranged in the recesses and fastened to the separators. One of the rings has a fastener pin (73) passing by the bushing. The fitting is co-operated with another ring.</p> |
