Variable-pitch vane made of composite material for an unducted fan of an aircraft

Abstract

A variable-pitch vane made of a composite material for an unducted fan of an aircraft, the vane including a fibrous reinforcement formed as a single piece of three-dimensional fabric including an airfoil portion and a root portion forming a retaining bulb and intended to be connected to a variable-pitch mechanism, the three-dimensional weaving being carried out continuously between the root portion and the airfoil portion, the fibrous reinforcement defining an internal shaping cavity formed by a separation extending inside the root portion and the blade portion, where-in a matrix densifies the fibrous reinforcement and reinforcing met-al shells are arranged around the root portion.
