Abstract: A structure comprising a nacelle or a thrust reverser, the structure comprising a stationary part and a movable part, the structure comprising: a first guide provided on or in the stationary part of the structure or the movable part of the structure; a first electrical connector attached to the stationary part of the structure: a second electrical connector attached to the movable part of the structure; and a carriage movable along the first guide: wherein the carriage comprises a closed loop electrical cable mounted in or on a carriage body such that the closed loop cable can rotate, wherein the first electrical connector is electrically connected to the closed loop electrical cable and the closed loop electrical cable is electrically connected to the second electrical connector, thereby providing an electrical connection from the stationary part of the structure to the movable part of the structure.

Abstract: An acoustic treatment panel intended to be disposed on at least one wall of an aircraft propulsion unit in contact with a fluidic flow, the panel including a first, acoustically reflective skin, a second, acoustically porous skin intended to be in contact with the fluidic flow, and a honeycomb structure extending between the first skin and the second skin and having a plurality of cavities. The panel includes at least one acoustically transparent reinforcing wall passing through a plurality of cavities of the honeycomb structure and extending from the second skin to the first skin, forming a non-orthogonal angle with the first and second skins.
