1. A thrust reverser for an aircraft propulsion assembly, said thrust reverser comprising:
a fixed structure; and
a door movable between:
a closed position wherein the door delimits with the fixed structure a flow conduit, the flow conduit comprising an ejection outlet delimited at least partly by a rear end of the fixed structure, the door in the closed position being configured to be able to guide a fluid flowing in the conduit to the ejection outlet in order to generate a thrust, and
an open position wherein the door releases a reversal opening so as to be able to evacuate from the flow conduit a portion of said fluid, via said reversal opening, and redirect a first portion of the fluid thus evacuated to a front end of the fixed structure in order to generate counter-thrust, the opening of the door forming a lateral opening extending between the fixed structure and a lateral end of the door,
wherein said thrust reverser comprises only on one side of a first median longitudinal plane of the thrust reverser, one of the door and the fixed structure, or each of the door and the fixed structure, comprises a deflector configured to be able to redirect a second portion of the fluid forward of the fixed structure, said second portion of the fluid exiting the flow conduit along a trajectory oriented towards said lateral opening,
wherein the deflector comprises one or more channels for redirecting said second portion of the fluid,
wherein the deflector extends radially between an inlet of said one or more channels on an internal surface of the door and an outlet of said one or more channels on an external surface of the door, at least when the door is closed,
wherein the internal surface of the door defines the flow conduit when the door is in the closed position, and the external surface of the thrust door is an external surface of the reverser in the closed position, and
wherein the deflector is configured so that the inlet of the one of more channels is closed off by the fixed structure when the door is closed.
