An aircraft nacelle including an automatically-operated locking device for limiting deformations of the cowl. This automatically-operated locking device includes at least one locking post connected to the cowl, at least one latch able to move between a first position corresponding to a locked state in which the latch prevents the locking post from becoming distanced from a fixed structure and a second position corresponding to an unlocked state in which the latch allows the locking post to become distanced from the fixed structure, at least one return system configured to hold the latch in its second position corresponding to the unlocked state, the cowl holding the latch in its first position when the cowl is in the closed position and allowing the latch to pivot toward its second position when the cowl is in the open position.

An acoustic absorption structure comprising a plurality of resonators. Each resonator comprises a first chamber which has a first mouthpiece delimited by an edge pressed against an inner surface of a porous zone of a skin so that the first chamber and the skin delimit a first cavity, a second chamber, in which is positioned the first chamber, which delimits, with the first chamber, a second cavity, at least one acoustic orifice passing through the first chamber, at least one drainage orifice passing through the first chamber and at least one drainage hole passing the second chamber, each drainage orifice and each drainage hole being configured to limit an accumulation of fluid in the resonator. Also, an aircraft propulsive assembly or an aircraft comprising the acoustic absorption structure are provided.

A nacelle comprising a fixed structure with a fixed cowl and a duct, a mobile assembly with a chassis forming a frame and a mobile cowl, the chassis being mobile, relative to the fixed structure, in translation between an advanced position and a retracted position to open an opening through the frame between the duct and the outside. The mobile assembly comprises at least one threaded rod parallel to the direction of displacement and fixed to the chassis through the frame. The fixed structure comprises an outer, an inner, and at least one intermediate box fixed to the inner box and to the outer box. For each threaded rod, the fixed structure comprises a motorized ball nut which meshes with the threaded rod, and an actuator which turns the ball nut and is fixed to at least one box from among the outer, the inner, or the intermediate box.
