Abstract

L'invention concerne une chambre de combustion pour moteur à turbine à gaz dont l'injecteur 28 comporte une double alimentation en carburant par deux tubes concentriques 30 et 32 dans lesquels le carburant est mélangé à de l'air mis en tourbillon par des aubes tourbillonnaires 36 et 38, l'arrivée de carburant aux deux tubes se faisant, en proportions variables selon le régime du moteur, par deux rampes séparées d'injection 40 et 42 sous la commande d'un régulateur de carburant soumis à un paramètre du moteur, et les deux tubes s'évasant à leur extrémité aval débouchant dans la chambre de combustion 16 pour y créer des tourbillons toroïdaux 100 et 200 de sens et de vitesse appropriés à une nébulisation optimale. Le dispositif permet de réduire la formation de fumées et de gaz nocifs quel que soit le régime du moteur et s'applique à tous les types de chambres de combustion: tubulaires, annulaires ou tubannulaires.
