Abstract
An aeroengine exhaust cone is arranged to extend from upstream to downstream along a longitudinal axis. The cone comprises a structural core of composite material made up of an axisymmetric part having an upstream endpiece at its upstream end and a downstream endpiece at its downstream end. The core provides structural strength to the cone. The cone has an acoustic attenuation system made of composite material and fastened on the structural core.
