The invention relates to an annular combustion chamber (10) for a turbine engine, comprising a chamber bottom (22), a plurality of air and fuel injection systems peripherally distributed about an axis (34) of the combustion chamber and mounted on the bottom of the chamber (22), and an air collector (100) which is associated with each injection system, said air collector comprising at least one wall (96, 98) mounted on the bottom of the chamber (22) and projecting upwardly in order to obstruct a peripheral air flow about the axis (34) of the combustion chamber. Said chamber also comprises an air inlet (88) formed at the upstream end of the air collector (100) and radially open towards the outside in relation to an axis (44) of the injection system.
Chambre annulaire de combustion (10) destinée à équiper une turbomachine, comprenant un fond de chambre (22), une pluralité de systèmes d'injection d'air et de carburant répartis circonf érentiellement autour d'un axe (34) de la chambre de combustion et montés sur le fond de chambre (22), et, associé à chaque système d'injection, un collecteur d'air (100) qui comprend au moins une paroi (96, 98) montée sur le fond de chambre (22) et se projetant vers l'amont pour former obstacle à un écoulement circonf érentiel d' air autour de l'axe (34) de la chambre de combustion, ainsi qu'une ouverture d'admission d'air (88) formée à l'extrémité amont du collecteur d'air (100) et ouverte radialement vers l'extérieur par rapport à un axe (44) du système d'injection.
