Aircraft propulsion assembly equipped with a thrust-reversing device comprising at least one inflatable barrier, and aircraft comprising at least one such propulsion assembly

An aircraft propulsion assembly comprising:

• a powering system,
• a nacelle surrounding the powering system,
• an annular duct, between the powering system and the nacelle in which, in operation, a flow of air circulates from upstream to downstream,
• a thrust-reversing device comprising at least one lateral aperture, passing through the nacelle and configured to be in an open state or a closed state, and
• at least one inflatable barrier configured to be in a folded down position in which the at least one barrier does not protrude into the annular duct and a deployed position in which the at least one inflatable barrier extends across the annular duct to deflect at least a part of the flow of air circulating in the annular duct toward the at least one lateral aperture, the at least one inflatable barrier having a first edge secured to the nacelle and a second edge at a distance from the first edge and configured to be in contact with the powering system in deployed position;
• wherein the at least one inflatable barrier is configured to be in a deflated state, in the folded down position, in which the at least one inflatable barrier is flexible, and an inflated state, in a deployed position, in which the at least one barrier is substantially rigid or semi-rigid, and
• wherein the thrust-reversing device comprises at least one supply system configured to supply the at least one inflatable barrier with a fluid,
• wherein the nacelle comprises a front part and a rear part that is movable between an upstream position in which the rear part is in contact with the front part and a downstream position in which the rear part is spaced apart from the front part, the lateral aperture being situated between the front and rear parts, and
• wherein the rear part comprises at least one housing that is open toward the front part and configured to at least partially house the at least one barrier in the deflated state,
• wherein the thrust-reversing device comprises at least one passage making it possible to connect the at least one housing and the annular duct when the rear part is in the upstream position and, for each of the at least one passage, at least one hatch that is movable between a closed position in which the at least one hatch shuts the at least one passage and an open position in which the at least one hatch frees the at least one passage.

• wherein the thrust-reversing device comprises at least one supply system configured to supply the at least one inflatable barrier with a fluid,
• wherein the at least one inflatable barrier comprises at least one orifice passing through the at least one inflatable barrier and configured such that, when the at least one inflatable barrier is in the inflated state, a zone of the annular duct situated upstream of the at least one inflatable barrier is therewith connected with a zone of the annular duct situated downstream of the at least inflatable barrier.
