Abstract
Official abstract text for this publication.
A fuel injector for a gas turbine engine may include an injector housing having a central cavity configured to be fluidly coupled to a combustor of the turbine engine. The central cavity may also be configured to direct a first fuel into the combustor substantially unmixed with air. The fuel injector may also include an annular air discharge outlet circumferentially disposed about the downstream end of the central cavity. The air discharge outlet may be configured to discharge compressed air into the combustor circumferentially about the first fuel from the central cavity. The fuel injector may also include an annular fuel discharge outlet circumferentially disposed about the air discharge outlet at the downstream end. The fuel discharge outlet may be configured to discharge a second fuel into the combustor circumferentially about the compressed air from the air discharge outlet.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel injector for a gas turbine engine comprising: an injector housing including a central cavity extending along a longitudinal axis from an upstream end to a downstream end, the downstream end of the central cavity configured to be fluidly coupled to a combustor of the turbine engine, the central cavity also configured to direct a first fuel into the combustor substantially unmixed with air; an annular air discharge outlet circumferentially disposed ab…
