Abstract

Mélangeur dont les améliorations quant à la poussée ne sont pas annihilées par une augmentation de poids et de la trainée. Il comprend une enveloppe 47 destinée à capter une partie de l'écoulement de dérivation équivalente à un taux de dilution sensiblement égal à 2 et un mélangeur multilobe 48 disposé à l'intérieur de cette enveloppe pour mélanger la partie de l'écoulement de dérivation captée, à l'écoulement de gaz chauds. Application aux turbo-réacteurs dilués.
