Abstract

L'invention concerne un dispositif d'échappement multicanal de turbomachine, du type multicanal à entré annulaire, comprenant une enveloppe extérieure de forme générale symétrique par rapport à un axe et au moins une séparation interne définissant plusieurs canaux sensiblement concentriques pour l'écoulement du flux d'échappement, un revêtement absorbant capable d'absorber une partie de l'énergie acoustique générée par l'écoulement est prévu sur au moins une surface de la séparation interne et/ou sur une surface interne de l'enveloppe extérieure. L'épaisseur du revêtement absorbant est adaptée sur la longueur du dispositif d'échappement pour optimiser l'écoulement dans les différents canaux en maintenant la diffusion progressive et en évitant les décollements au voisinage des surfaces immobiles. Grâce à cette disposition, la signature acoustique de la turbomachine est grandement réduite puisqu'il devient possible de bénéficier de l'augmentation de surface traitée acoustiquement due à la présence des séparations internes.
