<p>The blade (1) has a longitudinal member (10) i.e. longitudinal compartment, for taking up forces associated a socket pin (3). The longitudinal member comprises a centrifugal force recovery unit (20) of a part of a casing (30). The recovery unit comprises two chambers (21, 22), where each chamber is traversed by the pin. Each chamber comprises a retention belt (23) extending along a closed span of the blade. The belt is provided with unidirectional fibers wound around the pin. The casing is provided with inclined fibers having an angle with respect to the unidirectional fibers.</p> |
