Abstract
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 α such that 0°<α≤90°.
