摘要： A barrier structure (302) blocks exit of spring clip fragments (317) that may break off from a spring clip assembly disposed between a gas turbine engine combustor (300) and a transition piece component (360). The barrier structure (302) may additionally comprise an aspect (326) effective to restrict a spring clip's (310, 311) radially inward compression, thereby reducing or eliminating damage to the spring clip (310, 311) during shipping and handling. The barrier structure (302) additionally may comprise an aspect (330) to restrict access by a human hand to the free ends (318) of the spring clips (310, 311). This aspect (330) reduces or eliminates the undesired lifting of the compressor by grabbing the spring clips (310, 311) during combustor transport, installation or removal. Accordingly, barrier structure embodiments are provided that reduce stress on spring clips, and that prevent the exit of spring clips from a containment space partly formed by the barrier structure.
摘要翻译：阻挡结构（302）阻止可能从设置在燃气涡轮发动机燃烧器（300）和过渡件部件（360）之间的弹簧夹组件脱离的弹簧夹片（317）的出口。阻挡结构（302）可以另外包括有效地限制弹簧夹（310,311）径向向内压缩的方面（326），从而减少或消除在运输和处理期间弹簧夹（310,311）的损坏。阻挡结构（302）还可以包括限制人手接近弹簧夹（310,311）的自由端（318）的方面（330）。该方面（330）通过在燃烧器运输，安装或拆卸期间抓住弹簧夹（310,311）来减少或消除压缩机的不期望的提升。因此，提供了减小弹簧夹子上的应力并且防止弹簧夹从由阻挡结构部分形成的容纳空间的出口的阻挡结构实施例。

摘要： A fuel/air mixing apparatus, such as a main swirler assembly (400) comprising a sleeve (410), provides for additional air entry around the perimeter of a bore (440) through which passes a fuel/air mixture. The additional air reduces or eliminates flashback during operation of a gas turbine comprising the assembly (400). In some embodiments, a plurality of gaps (464) exists between spaced apart tabs (462) along a downstream end (460) of the sleeve (410). During gas turbine operation, air flows through both a flashback annulus (411) and the gaps (464). In other embodiments, a plurality of holes are placed upstream and in line with the tabs (1004) to supplement the air flow through gaps (1006). In yet other embodiments, rows (1102) of holes (1104) are provided to supplement the airflow. Downstream ends (460,1218) may interface with a downstream-oriented lip (460) or with an upstream-oriented lip (1224). The interfacing may comprise a fit effective to damp vibration and to increase the natural frequency.
摘要翻译：诸如包括套筒（410）的主旋流器组件（400）的燃料/空气混合设备提供围绕通过燃料/空气混合物的孔（440）的周边的附加空气进入。在包括组件（400）的燃气涡轮机的操作期间，附加空气减少或消除了回火。在一些实施例中，沿着套筒（410）的下游端（460）的间隔开的突片（462）之间存在多个间隙（464）。在燃气轮机操作期间，空气流过回流环（411）和间隙（464）。在其他实施例中，多个孔被放置在上游并且与突片（1004）成一直线，以补充通过间隙（1006）的空气流。在其它实施例中，提供孔（1104）的孔（1104）以补充气流。下游端（460,1218）可以与下游定向的唇缘（460）或与上游取向唇缘（1224）相接触。接口可以包括有效地阻尼振动并增加固有频率的配合。
