Abstract

L'invention concerne une turbomachine comportant une chambre de combustion annulaire. Cette chambre comprend des parois annulaires 15, 16 s'étendant dans la direction de l'axe 13A de la chambre et formant un conduit annulaire de pré-mélange 33 ayant à une de ses extrémités axiales une entrée d'air annulaire 30 et ayant à son autre extrémité axiale une rangés annulaire de sorties 35, des parois 14A, 17A formant la zone principale de la chambre disposées en série avec le conduit et des parois formant deux zones pilotes annulaires situées respectivement radialement à l'intérieur et à l'extérieur dudit conduit.
