Abstract

L'invention propose un ensemble pour arrière corps de turbomachine à double-flux (10) ayant un axe longitudinal (X), comprenant : une tuyère secondaire (110) définie autour de l'axe longitudinal (X), ladite tuyère secondaire étant configurée pour éjecter un mélange des flux issus d'une veine secondaire (Vs) et d'une veine primaire (Vp) de la turbomachine (10), la tuyère secondaire étant de forme convergente-divergente avec un col (112) correspondant à une section minimale de la tuyère secondaire (110), un échangeur thermique avec fluide caloporteur disposée au moins sur une portion de la circonférence interne de la tuyère secondaire (110) longitudinalement en amont du col (112), l'échangeur thermique comprenant une pluralité d'ailettes orientées radialement vers l'intérieur de la tuyère.
