Abstract
(EN)
Improved fuel atomization for turbine engines operating at low fuel flows and at high altitudes is accomplished in an engine (10) having an annular combustor (12) by utilizing fuel injectors (18) provided with fuel supply tubes (24) disposed within air tubes (20) wherein the fuel supply tubes (24) each have an exit orifice (26) internally of the corresponding air tube (20) and upstream of an exit orifice (22) thereof with a fuel impingement surface (28) being provided within the air tube (20) in confronting relation to the exit orifice (26) of the fuel supply tube (24) to produce a conical fuel film (36) subjected to pressurized air to enhance fuel atomization.
(FR)
On obtient une meilleure atomisation du carburant pour des moteurs à turbine fonctionnant à des écoulements de carburant faibles et à des altitudes élevées, dans un moteur (10) comportant un brûleur annulaire à deux étages de gazéification (12), par l'utilisation d'injecteurs de carburant (18) dotés de tubes (24) d'alimentation en carburant disposés à l'intérieur de tubes d'air (20), dans lesquels lesdits tubes d'alimentation en carburant (24) comportent chacun un orifice de sortie (26) situé à l'intérieur du tube d'air correspondant (20) et dotés en amont d'un orifice de sortie (22) de ce dernier, d'une surface d'incidence de carburant (28) disposée à l'intérieur dudit tube d'air (20) et située en face de l'orifice de sortie (26) dudit tube d'alimentation en carburant (24), afin de produire un film de carburant conique (36) soumis à de l'air pressurisé afin d'augmenter l'atomisation du carburant.
