The invention relates to a straightening assembly () comprising two radially inner and outer coaxial shells () between which extend vanes () made of composite material, fixed to a first end portion on the radially inner shell and to a second end portion on the radially outer shell, characterized in that:

Turbine engine comprising a straightening assembly

The invention concerns a flow straightener unit () for a fan module of a turbomachine, the straightener unit () comprising a plurality of blades () distributed about an axis of rotation, each blade () is made of a composite material and comprises an aerofoil () and a root () intended to be assembled on a hub () of the turbomachine. The unit () comprises a centring and attachment plate () of the blade () on the turbomachine intended to be attached to the hub () at a determined azimuthal position and to the root () of the blade (), the plate () is designed to be screwed to the hub () by screws () that are longitudinal with respect to the axis of rotation of the unit () and screwed to the root () of the blade () by screws () that are radial with respect to the axis of rotation of the unit ().

Flow straightener unit comprising a centering and attachment plate

The invention relates to a straightening assembly for an air flow of a turbomachine, comprising two respectively coaxial radially inner and outer shrouds (), between which extend the vanes () made of composite material attached, at a first end portion () thereof, to the radially inner shroud and at a second end portion () thereof, to the radially outer shroud (), with the vanes () comprising a useful portion extending between the two end portions (). According to the invention, for each vane () in a plane perpendicular to the axis of the radially inner and outer shrouds (), a straight line passing through a junction between said first and second end portions () and the useful portion forms, with a radius of the radially inner shroud passing through the junction between said first end portion and the useful portion of said vane (), an angle &#x3b1; such that 0&#xb0;&#x3c;&#x3b1;&#x2264;90&#xb0;.

Air flow straightening assembly and turbomachine including such an assembly

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.
