An aircraft nacelle includes a first conduit for an air inlet and a second conduit for an engine, arranged end to end and connected by an annular flange, attached to the air inlet, and an annular flange, attached to the engine. The annular flanges are connected by a plurality of passage holes in the annular flanges and arranged in line with each other. Rods are housed in the passage holes. For at least one rod, the passage hole of one of the annular flanges has a diameter greater than the diameter of the rod allowing the rod to move in case of deformation of one of the two conduits. An angle profile is inserted between the rod and a cylindrical portion adjacent to the annular flange and is connected to the adjacent cylindrical portion through the intermediary of at least one mechanism for absorbing eventual deformations in radial direction.

Fastening device particularly suitable for the fastening between an air intake and an engine of an aircraft nacelle

An acoustic treatment panel that is connected to an air intake of an aircraft nacelle, includes at least one acoustically resistive structure () and a reflective layer (), between which are located&#x2014;in a direction that is essentially perpendicular to the longitudinal direction of the nacelle&#x2014;bands () of alveolar cells spaced in such a way as to allow the passage of hot air provided for a frost treatment, characterized in that it includes pipes () for hot air that are each delimited by at least one partition that extends from the acoustically resistive layer () up to the reflective layer () in such a way as to insulate the bands () of cells in the longitudinal direction.

Acoustic processing panel, more particularly adapted for an air intake in an aircraft nacelle

Disclosed is an aircraft turbine engine. The turbine engine includes an air intake having a tubular internal wall and a fan enclosed by a tubular fan casing, and the rear end of the said air intake internal wall and the front end of the fan casing are joined together by at least one fastener. The air intake internal wall, the fan casing, or both, are comprised of a resin/fiber composite. The rear end of the air intake internal wall and the front end of the fan casing are uniform, and have no projections that join the internal wall and casing together.
