In a thrust reverser for an aircraft propulsion unit, the thrust reverser includes an internal fixed structure, a mobile cowl and blocking flaps. The thrust reverser also includes a first actuation mechanism that is configured to move the mobile cowl between a closing position and an opening position so as to cause the blocking flaps to move respectively between a retracted position and a deployed position, thus causing the thrust reverser to pass respectively between a full-thrust configuration and a thrust-reversal configuration. The thrust reverser also includes a second actuation mechanism that is configured to move the blocking flaps between the retracted position and a partially deployed position when the mobile cowl is in the closing position, so as to cause the thrust reverser to pass respectively between the full-thrust configuration and a reduced-thrust configuration.

The invention relates to an assembly for a turbomachine extending along an axis (X) and comprising: &#x2014;a ferrule () designed to define a fan duct () of a gas stream of the turbomachine, &#x2014;a fan casing () radially surrounding the ferrule () and defining with the ferrule () the fan duct (), &#x2014;a rectifier () comprising a plurality of vanes () comprising a first vane () and a second vane () adjacent to the first vane (), the vanes defining between them a converging flow channel () designed to direct and accelerate the stream by means of an inlet section () included in a plane non-perpendicular to the axis of the turbomachine and an outlet section included in a plane () perpendicular to the axis (X) of the turbomachine, the first vane () and the second vane () each having an unducted downstream portion which forms a trailing edge.
