Abstract

Un système (1) de combustion à volume constant pour turbomachine comprenant une pluralité de chambres de combustion (2) réparties de manière annulaire autour d'un axe principal (θ ), lesdites chambres de combustion (2) comprenant des orifices d'admission (21) et des orifices d'échappement (22), le système (1) comprenant un sélecteur (3) mobile en rotation autour de l'axe principal (θ ) qui est configuré pour obturer et ouvrir sélectivement les orifices d'admission (21) et les orifices d'échappement (22) lors de la rotation dudit sélecteur (3), caractérisé en ce qu'au moins un canal d'injection de carburant (34) est formé dans ledit sélecteur (3) pour injecter sélectivement le carburant dans les chambres de combustion (2) lors de la rotation dudit sélecteur (3).A constant volume combustion system (1) for a turbomachine comprising a plurality of combustion chambers (2) distributed annularly around a main axis (θ), said combustion chambers (2) comprising intake orifices ( 21) and exhaust ports (22), the system (1) comprising a selector (3) movable in rotation around the main axis (θ) which is configured to selectively close and open the intake ports (21 ) and the exhaust ports (22) during rotation of said selector (3), characterized in that at least one fuel injection channel (34) is formed in said selector (3) for selectively injecting fuel in the combustion chambers (2) during the rotation of said selector (3).
