ABSTRACT:
A packing member for restraining the root of a fan blade in a socket of a rotor disk takes the form of a curvilinear plate comprising a metallic sub-structure having recessed portions and a semi-rigid elastomeric material molded into and filling the recessed portions. The member has a substantially metallic central area extending as far as the side edge of the member on the same side as the extrados face of the blade, the metallic central area having a machined profile set back relative to the profile of the socket so as to permit the root of the blade to rock in response to a violent impact on the blade. The packing member has upstream and downstream end areas which are entirely metallic, and the two side edges of the member upstream and downstream of the central area are defined by the elastomeric material. Between the two elastomeric side edges, both upstream and downstream of the metallic central area, the member has a metallic lower part and an upper part formed by the elastomeric material.
