Abstract
The invention relates to a thrust reversal system comprising: - at least one movable cowl (20), movable between a retracted position and a deployed position; - a set of air deflection devices (22); - at least one device (24) for closing the secondary flow stream (16a), movable between a retracted position corresponding to the retracted position of the movable cowl (20), in which the closing device is at least partially housed in a space (200) provided in the movable cowl (20), and a deployed position corresponding to the deployed position of the movable cowl (20), in which the closing device (24) is at least partially deployed in the secondary flow stream (16a), so as to deflect a majority portion of the secondary flow towards the air deflection devices (22); the thrust reversal system comprising at least one deployable membrane (22, 24), the deployable membrane (22, 24) comprising at least one reinforcement.
