Abstract

Un appareil (200) pour la régulation active du débit de carburant dune pompe à carburant (202) vers un ensemble mélangeur (100) dune chambre de combustion (26) dune turbine à gaz, où lensemble mélangeur (100) comprend un mélangeur pilote (102) et un mélangeur principal (104). Le mélangeur pilote (102) comprend en outre un logement pilote annulaire (108) avec un intérieur creux, un injecteur de carburant principal (110) monté dans le logement pilote (108) et adapté pour distribuer des gouttelettes de carburant dans lintérieur creux du logement pilote (108), une pluralité de coupelles rotatives axiales (112, 114) positionnées en amont de linjecteur de carburant principal (110). Lappareil de régulation du débit de carburant (200) comprend en outre : au moins un capteur (218) pour détecter la pression dynamique dans la chambre de combustion (26); une buse à carburant (68); et un système (204) pour réguler le débit de carburant fourni par la buse à carburant (68) au travers des soupapes (184, 186, 188). La buse à carburant (68) comprend : un ruban dalimentation (178) avec une pluralité de circuits (180, 182, 183) pour fournir du carburant au mélangeur pilote (102) et au mélangeur principal (104); et une pluralité de soupapes (184, 186, 188) associées à la buse de carburant (68) et en communication fluide avec la bande dalimentation (178) de celle-ci. Le système de régulation (204) active les soupapes (184, 186, 188) conformément aux signaux (216) reçus du capteur de pression (218).
