Abstract
A turboengine that reduces rear noise emissions has a thickness of a rear part of a sound-attenuating coating, which is borne internally by an external fan cowl, that is increased toward a front part of the sound-attenuating coating. An increased-thickness zone is connected to a pan of the coating, located in a critical area of a jet nozzle, by a surface having a curved profile.
