Abstract
The invention relates to thrust reversers with doors for a jet engine. The upstream edge of the reverser doors is equipped with a deflecting structure consisting of a rigid frame (10, 12, 13) fixed to the door and delimiting a space (14) capped by a stiffener (15). In the space (14) are housed vanes (16) with aerodynamic profile in the form of a wing which is inclined by an angle a with respect to the plane of the frame (10, 12, 13) in order to orient laterally the flow of the gases which is diverted by the reverser. This arrangement makes it possible to reduce, or even to prevent, re-ingestion by the engine of the diverted gases, or interference of the latter with the wing structure of the aircraft.
