Abstract
An assembly for the rear of a bypass turbomachine () comprises a primary nozzle () comprising a trailing edge defining a primary flow path portion and a secondary nozzle () defining a secondary flow path portion, defined about a longitudinal axis (X), said secondary nozzle being configured to eject a mixture of the flows coming from a secondary flow path (Vs) and from a primary flow path (Vp) of the turbomachine (), the secondary nozzle being of convergent-divergent shape with a throat () corresponding to a minimum cross section of the nozzle (), the secondary nozzle () comprising, at the throat (), a periodic succession of lobes () which are situated along the internal circumference of the secondary nozzle (). The assembly also comprises a lobed mixer () at the downstream end of the primary nozzle (), this having an alternation of hot lobes () extending inside the secondary flow path and of cold lobes () extending inside the primary flow path. The lobes of the nozzle () which are concave (), which is to say radially towards the outside, and respectively which are convex (), which is to say radically towards the inside, if the longitudinal offset is disregarded, radically face the respectively hot lobes () and cold lobes () of the mixer ().
