    • A transition duct (300) for use in a turbine engine (10) is provided. The transition duct (300) includes a radially inner wall (304) and a radially outer wall (208) positioned about the radially inner wall (304) defining a flow passage (306) therebetween. The radially outer wall (208) extends and is contoured from an upstream end (310) to a downstream end (320) of the transition duct (300). As such, the slope of the radially outer wall (208) increases from the upstream end (310) to a predetermined axial location (308) and decreases from the predetermined axial location (308) to the downstream end (320). A turbine assembly comprising such a transition duct (300) between its high pressure turbine (18) and its low pressure turbine (20). A corresponding method of assembling a transition duct (300) for use in a turbine assembly.
    • 提供一种用于涡轮发动机(10)的过渡管道(300)。 过渡管道(300)包括径向内壁(304)和围绕径向内壁(304)定位在其间的流动通道(306)的径向外壁(208)。 径向外壁(208)从过渡管道(300)的上游端(310)延伸到下游端(320)。 这样,径向外壁(208)的斜面从上游端(310)增加到预定的轴向位置(308),并从预定的轴向位置(308)减小到下游端(320)。 一种涡轮组件,包括在其高压涡轮机(18)和其低压涡轮机(20)之间的这种过渡管道(300)。 组装用于涡轮组件的过渡管道(300)的相应方法。
