摘要： A fuel injector for a gas turbine engine may include a pilot assembly extending along a longitudinal axis. The pilot assembly may be configured to direct a pilot fuel-air mixture to a combustor of the gas turbine engine. The fuel injector may also include a rich catalyst module circumferentially disposed about the pilot assembly. The catalyst module may be configured to simultaneously direct a stream of compressed air and a stream of first fuel-air mixture therethrough without intermixing. The fuel injector may also include a post mix zone disposed downstream of the catalyst module. The post mix zone may be configured to mix the compressed air and the first fuel air mixture to create a main fuel-air mixture. The fuel injector may further include an air swirler disposed downstream of the post mix zone. The air swirler may be configured to direct the main fuel-air mixture to the combustor without intermixing with the pilot fuel-air mixture.
摘要翻译：用于燃气涡轮发动机的燃料喷射器可以包括沿纵向轴线延伸的导向组件。导向组件可以被配置成将先导燃料 - 空气混合物引导到燃气涡轮发动机的燃烧器。燃料喷射器还可以包括围绕导向组件周向设置的富催化剂模块。催化剂模块可以被配置成同时引导压缩空气流和第一燃料 - 空气混合物流而不混合。燃料喷射器还可以包括设置在催化剂模块下游的后混合区域。后混合区可以被配置为混合压缩空气和第一燃料空气混合物以产生主要的燃料 - 空气混合物。燃料喷射器还可以包括设置在后混合区域下游的空气旋流器。空气旋流器可以被配置成将主燃料 - 空气混合物引导到燃烧器，而不与先导燃料 - 空气混合物混合。
