Title
(EN) FLOW STRAIGHTENER UNIT COMPRISING A CENTRING AND ATTACHMENT PLATE
(FR) ENSEMBLE DE REDRESSEUR DE FLUX COMPRENANT UNE PLATINE DE CENTRAGE ET DE FIXATION
Abstract
(EN)
The invention concerns a flow straightener unit (1) for a fan module of a turbomachine, the straightener unit (1) comprising a plurality of blades (2) distributed about an axis of rotation, each blade (2) is made of a composite material and comprises an aerofoil (21) and a root (22) intended to be assembled on a hub (4) of the turbomachine. The unit (1) comprises a centring and attachment plate (3) of the blade (2) on the turbomachine intended to be attached to the hub (4) at a determined azimuthal position and to the root (22) of the blade (2), the plate (3) is designed to be screwed to the hub (4) by screws (51a) that are longitudinal with respect to the axis of rotation of the unit (1) and screwed to the root (22) of the blade (2) by screws (52) that are radial with respect to the axis of rotation of the unit (1).
