摘要： A gas turbine combustor assembly includes a fuel injector, a dome stator around the fuel injector, and a dome sleeve coupled to the dome stator. The dome sleeve defines an air inlet opening with the dome stator, and is carried to move with respect to the dome stator to change a flow area of the air inlet opening. The dome sleeve also defines a nozzle sloping downstream from the air inlet opening toward an outlet of the combustor assembly. The sloping nozzle defines an annular pinch gap adjacent an outlet of the fuel injector, and is coupled to move with the dome sleeve to change a flow area through the pinch gap.

摘要翻译： 燃气轮机燃烧器组件包括燃料喷射器，围绕燃料喷射器的圆顶定子以及联接到圆顶定子的圆顶套筒。 圆顶套筒限定了具有圆顶定子的空气入口开口，并被承载为相对于圆顶定子移动以改变进气口的流动面积。 圆顶套筒还限定了一个从空气入口开口朝向燃烧器组件的出口倾斜的喷嘴。 倾斜喷嘴限定与燃料喷射器的出口相邻的环形夹紧间隙，并且联接成与圆顶套筒一起移动以改变通过夹紧间隙的流动面积。
