A cascade-type thrust reverser includes a fixed structure on which a rear frame supporting cascades of vanes is mounted, a mobile structure having an outer wall, an inner wall formed in part by an acoustic panel, a partition connecting the outer wall to the acoustic panel, and actuators interposed between the fixed structure and the mobile structure. The actuators extend through orifices formed in the rear frame and the partition. In particular, the rear frame radially interferes with the acoustic panel when the mobile structure is in a direct-jet position.

A mobile cowl for a cascade-type thrust reverser includes an interior wall having an anterior zone, a movably mounted shutter and a link rod of which one end is connected to the shutter to actuate the shutter from one position to other. One of the positions may be a direct-jet position in which the shutter is situated facing the anterior zone, and other position may be a reverse-jet position in which the shutter is situated away from the anterior zone. The interior wall has, in the anterior zone, a part able to allow the link rod end to move beyond a normal position in the event of abnormal movements of the link rod end, without wrecking the interior wall.

A thrust reverser for a turbojet engine is disclosed in which the thrust erser baffles have one or more deflectors to direct the cold gas flow over an inner surface of the baffles to ensure that the inner surface remains out of contact with the hot gas flow. The deflectors are movably mounted on the baffles such that, when the baffles are in their forward thrust positions, the deflectors are retracted so as to be generally flush with the inner surface of the baffle so as not to interfere with the forward thrust flow of gases. The deflectors may be automatically deployed to their extended positions when the baffles are moved to their reverse thrust positions.
