Abstract

See full text

A stator configuration for a gas turbine engine including: a splitter segment, the splitter segment extending from a forward end to a rearward end, the splitter segment being configured to split an incoming fluid flow into a first, radially outer stream and a second, radially inner stream; a forward most first stator extending radially outwardly from the splitter segment, the forward most first stator being completely located downstream from the forward end of the splitter segment; a forward most second stator extending radially inwardly from the splitter segment, the splitter segment, the forward most first stator and the forward most second stator being formed as a single, integrally formed structure, the forward most first stator positioned closer to the forward end relative to a distance between the forward most second stator and the forward end and the forward most second stator positioned closer to the rearward end relative to a distance between the forward most first stator and the rearward end, wherein the splitter segment defines a radially outward boundary of the second, radially inner stream such that an outer tip of a rotor passes in close proximity to the splitter segment at the radially outward boundary of the second, radially inner stream defined by the splitter segment; and a sacrificial rub layer located within a pocket formed in a radially inner surface of the splitter segment that faces the outer tip of the rotor at the radially outward boundary of the second, radially inner stream defined by the splitter segment.
