TURBINE STATOR VANES HAVING INSERTS AND SPLITTER PLATES

A stator of a turbine section, has: vanes distributed around a central axis, a vane of the vanes extending along a spanwise axis and defining an internal passage; an insert received within the internal passage, the insert defining a cavity for receiving cooling air and defining impingement cooling apertures facing an inner face of the vane; a splitter plate secured within the cavity and being transverse to the spanwise axis, the splitter plate having a base secured to the insert and a tip protruding from the base; and a flow passage defined between the tip and the insert, the flow passage fluidly connecting a first section of the cavity to a second section of the cavity, the tip of the splitter plate secured to the insert at at least one location along a perimeter of the tip.
