Abstract

A turbine engine assembly (86) includes a vane structure (88) and an inner structure (182). The vane structure (88) includes a plurality of structure segments (106) arranged circumferentially about an axis (32). Each of the structure segments (106) includes an inner platform segment (114), an outer platform segment (162) and an airfoil (177). The inner platform segment (114) includes a base (128) and a tab (130). The tab (130) is connected to and projects laterally out from the base (128). The tab (130) is radially next to and extends laterally along the base (128) of the inner platform segment (114) of a respective circumferentially neighboring one of the structure segments (106). The airfoil (177) extends radially across a flowpath (78) and is connected to the inner platform segment (114) and the outer platform segment (162). The inner structure (182) extends circumferentially around the axis (32). The inner structure (182) is configured with a plurality of pins (198). Each of the pins (198) projecting axially into an aperture (146) in the base (128) of a respective one of the structure segments (106).
