Title
(EN) RADIALLY MOUNTED AIR BLAST FUEL INJECTOR
(FR) INJECTEUR RADIAL DE CARBURANT, A ENTRAINEMENT D'AIR
Abstract
(EN)
A fuel nozzle (18) for a gas turbine engine comprises a nozzle stem (55), a nozzle tip assembly (60) and a nozzle sheath (50). A plurality of inlets (82) allow air to flow into the interior (90) of the sheath (50); fuel is flowed into the nozzle (18) through a fuel passage (135) in fluid communication with a fuel manifold. The fuel enters a fuel channel (140) defined by the stem (55) and tip assembly (60), and then passes into a fuel gallery (185) through a plurality of metering holes (190). Fuel swirls out of the tip assembly (60), where it is caught between, and squeezed by, first and second streams of air passing out of radially spaced apart air passages (145) and (220).
(FR)
Injecteur (18) de turbine à gaz comportant une tige (55), une tête (60) et une gaine (60). La gaine (50) est percée de plusieurs orifices admettant l'air à l'intérieur (82). Le carburant est admis dans la tuyère (18) par un passage (135) communiquant avec le collecteur de carburant. Il passe ensuite dans un canal (140) constitué par la tige (55) et la tête (60), puis traverse une galerie (185) pourvue de plusieurs orifices calibrés (190). Le carburant sort en tourbillonnant de la tête (60) et est pris et brassé entre les deux courants d'air provenant respectivement des passages (145) et (146) espacés radialement.
