Title
(EN) VARIABLE SWIRL FUEL NOZZLE
(FR) GICLEUR D'INJECTEUR DE CARBURANT À TURBULENCE VARIABLE
Abstract
(EN)
A fuel injector providing a flow of fuel having a variable swirl and/or variable effective area is disclosed. The fuel injector may have a nozzle defining a mixing chamber having an outlet proximate a centerline of the mixing chamber, a first fuel line in fluid communication with the mixing chamber and a second fuel line in fluid communication with the mixing chamber. The first fuel line may terminate in a tangential fuel inlet positioned tangential to the centerline of the nozzle, while the second fuel line may terminate in a radial fuel inlet positioned radial to the centerline of the nozzle.
(FR)
L'invention concerne un injecteur de carburant assurant un écoulement de carburant à turbulence variable et/ou à surface effective variable. L'injecteur de carburant peut comprendre un gicleur définissant une chambre de mélange comportant une sortie située à proximité d'une ligne médiane de la chambre de mélange, un premier conduit de carburant en communication fluidique avec la chambre de mélange et un second conduit de carburant en communication fluidique avec la chambre de mélange. Le premier conduit de carburant peut se terminer au niveau d'une entrée de carburant tangentielle positionnée de manière tangentielle par rapport à la ligne médiane du gicleur, tandis que le second conduit de carburant peut se terminer au niveau d'une entrée de carburant radiale positionnée de manière radiale par rapport à la ligne médiane du gicleur.
