    • A fuel injector for a turbine engine may include a body member disposed about a longitudinal axis, and a barrel member located radially outwardly from the body member. The fuel injector may also include an annular passageway extending between the body member and the barrel member from a first end to a second end. The first end may be configured to be fluidly coupled to a compressor of the turbine engine and the second end may be configured to be fluidly coupled to a combustor of the turbine engine. The fuel injector may also include a perforated plate positioned proximate the first end of the passageway. The perforated plate may be configured to direct compressed air into the annular passageway with a first pressure drop. The fuel injector may also include at least one fuel discharge orifice positioned downstream of the perforated plate. The at least one fuel discharge orifice may be configured to discharge a fuel into the annular passageway with a second pressure drop. The second pressure drop may have a value between about the first pressure drop and about 1.75 times the first pressure drop.
    • 用于涡轮发动机的燃料喷射器可以包括围绕纵向轴线设置的主体部件和从主体部件径向向外定位的筒部件。 燃料喷射器还可以包括从第一端到第二端在主体构件和筒构件之间延伸的环形通道。 第一端可以被配置为流体地联接到涡轮发动机的压缩机,并且第二端可被配置为流体地联接到涡轮发动机的燃烧器。 燃料喷射器还可以包括邻近通道的第一端定位的多孔板。 多孔板可以构造成以第一压降将压缩空气引导到环形通道中。 燃料喷射器还可以包括位于多孔板下游的至少一个燃料排放孔。 至少一个燃料排放孔可以构造成以第二压降将燃料排放到环形通道中。 第二压降可以具有在大约第一压力下降与第一压力下降约1.75倍之间的值。

    • A fuel injector for a gas turbine engine is disclosed. The fuel injector includes an injector housing having a longitudinal axis. The injector housing includes one or more fuel galleries annularly disposed about the longitudinal axis, and a compressed air inlet. The fuel injector also includes a premix barrel having a proximal end and a distal end circumferentially disposed about the longitudinal axis. The premix barrel is fluidly coupled to the fuel galleries and the compressed air inlet at the proximal end and is configured to couple to a combustor of the gas turbine engine at the distal end. The fuel injector also includes a substantially cylindrical pilot assembly disposed radially inwards of the premix barrel having a first end and a second end. The second end is coupled to the injector housing and the first end is located proximate the distal end of the premix barrel. The fuel injector further includes a pilot liquid tube having a third end and a fourth end disposed radially inwards of the pilot assembly. The fourth end is removably coupled to the injector housing and the third end is located proximate the first end of the pilot assembly.
    • 公开了一种用于燃气涡轮发动机的燃料喷射器。 燃料喷射器包括具有纵向轴线的喷射器壳体。 喷射器壳体包括围绕纵向轴线环形设置的一个或多个燃料库,以及压缩空气入口。 燃料喷射器还包括预混合桶,其具有围绕纵向轴线周向设置的近端和远端。 预混合桶在近端处流体耦合到燃料库和压缩空气入口,并且构造成在远端处耦合到燃气涡轮发动机的燃烧器。 燃料喷射器还包括基本上圆柱形的先导组件,其设置在具有第一端和第二端的预混料筒的径向向内。 第二端联接到喷射器壳体,并且第一端位于预混合筒的远端附近。 燃料喷射器还包括具有设置在导向组件的径向内侧的第三端和第四端的先导液体管。 第四端部可拆卸地联接到喷射器壳体,并且第三端部位于导向组件的第一端附近。
