    • An annular trapped vortex cavity assembly segment comprising includes a cavity forward wall, a cavity aft wall, and a cavity radially outer wall therebetween defining a cavity segment therein. A cavity opening extends between the forward and aft walls at a radially inner end of the assembly segment. Radially spaced apart pluralities of air injection first and second holes extend through the forward and aft walls respectively. The segment may include first and second expansion joint features at distal first and second ends respectively of the segment. The segment may include a forward subcomponent including the cavity forward wall attached to an aft subcomponent including the cavity aft wall. The forward and aft subcomponents include forward and aft portions of the cavity radially outer wall respectively. A ring of the segments may be circumferentially disposed about an axis to form an annular segmented vortex cavity assembly.
    • 环形捕获的涡流空腔组件段包括空腔前壁,空腔后壁和在其间形成空腔段的空腔径向外壁。 空腔开口在组装段的径向内端处在前壁和后壁之间延伸。 径向间隔开的多个空气喷射第一和第二孔分别延伸穿过前壁和后壁。 该段可以包括分段的远端第一和第二端处的第一和第二膨胀接头特征。 该段可以包括前向子部件,其包括附接到包括腔后壁的尾部子部件的空腔前壁。 前后副部件分别包括空腔径向外壁的前部和后部。 环的环可以围绕轴线周向设置以形成环形分段的涡流腔组件。
