Abstract

L'invention concerne une chambre de combustion (202) de turbomachine comprenant une paroi interne (212), une paroi externe (214) entourant la paroi interne de façon à délimiter avec celle-ci un espace annulaire formant un foyer de combustion, une pluralité de systèmes d'injection de carburant (220) comportant des injecteurs pilote (220a) alternant circonférentiellement avec des injecteurs plein gaz (220b), et au moins une ouverture d'admission d'air débouchant dans le foyer de combustion à l'extrémité amont de celui-ci et selon une direction sensiblement longitudinale. La paroi externe (214) comporte une pluralité de cavités pilote (222) s'étendant entre les deux extrémités longitudinales de la paroi externe et radialement vers l'extérieur de celle-ci, les cavités pilote étant alimentées en air extérieur à la chambre de combustion selon une même direction sensiblement circonférentielle. Chaque injecteur pilote (220a) débouche radialement dans une cavité pilote et chaque injecteur plein gaz (220b) débouche radialement entre deux cavités pilotes adjacentes.
