Abstract

Injecteur de combustible pour chambre de combustion d'un moteur à turbine à gaz comprenant une pointe de coupelle de tourbillonnement le long d'un axe ; et un adaptateur hélicoïdal le long de l'axe et dans la pointe de coupelle de tourbillonnement. Un procédé d'acheminement d'un gaz combustible et d'un liquide dans un injecteur de combustible jusque dans un moteur à turbine à gaz consiste à acheminer un écoulement de combustible primaire dans un insert hélicoïdal ; et à acheminer un écoulement de combustible secondaire autour de l'insert hélicoïdal.
