Abstract: A method for manufacturing a turbomachine vane made of composite material, the method including forming, by three-dimensional or multilayer weaving, a fiber blank separated across its thickness into first, second and third parts in two non-interlinked areas present at the longitudinal ends of the fiber blank, the first part located between the second and third parts to which it is connected by weaving outside non-interlinked areas, forming, from the fiber blank, a preform of the vane to be produced, by unfolding and shaping, at each longitudinal end and on either side of the first part, the segments of the second part and the segments of the third part not interlinked with the first part to form preform parts for a platform of the vane, the segments of the first part not interlinked with the segments of the second and third parts extending along the longitudinal axis, and densifying the preform.

Abstract: An outlet guide vane for a fan of a turbomachine is provided. The outlet guide vane includes a blade made of composite material and having a radial inner end, a first metal fastener portion fastened to the radial inner end, a first platform extending transversely with respect to the blade in the vicinity of the radial inner end. The first metal fastener portion is to be mounted on and fastened to an upstream flange and to a downstream flange of a hub. The first platform is monolithic with the first metal fastener portion or with the blade. A rectifier wheel and a turbomachine including the outlet guide vane are also provided.

Abstract: The invention describes an outlet guide vane (1) for a fan (2) of a turbomachine, comprising: a blade (10) made of composite material and having a radial inner end (101), a first metal fastener portion (11) fastened to the radial inner end (101), at least a first platform (13) extending transversely with respect to the blade (10) in the vicinity of its radial inner end (101), the first metal fastener portion (11) being configured to be mounted on and fastened to an upstream flange (62) and to a downstream flange (63) of a hub (6), the first platform (13) being monolithic with the first metal fastener portion (11) or with the blade (10). The invention also relates to a rectifier wheel (3) and to a turbomachine comprising such an outlet guide vane (1).
