Abstract
An assembly is provided for a turbine engine. This assembly includes a vane array structure and an air particle separator. The vane array structure includes an inner platform, an outer platform and a plurality of vanes. The inner platform forms an inner peripheral boundary of a flowpath through the vane array structure. The outer platform forms an outer peripheral boundary of the flowpath through the vane array structure. The vanes are arranged circumferentially about an axis. Each of the vanes extends radially across the flowpath from the inner platform to the outer platform. The vanes include a first vane. The air particle separator is arranged within the first vane.

An assembly for a turbine engine, comprising:
- a vane array structure including an inner platform, an outer platform and a plurality of vanes, the inner platform forming an inner peripheral boundary of a flowpath through the vane array structure, the outer platform forming an outer peripheral boundary of the flowpath through the vane array structure, the plurality of vanes arranged circumferentially about an axis, each of the plurality of vanes extending radially across the flowpath from the inner platform to the outer platform, and the plurality of vanes comprising a first vane;
- and
- an air particle separator arranged within the first vane.
An assembly for a turbine engine, comprising:
- a vane array structure including an inner platform, an outer platform and a plurality of vanes, the inner platform forming an inner peripheral boundary of a flowpath through the vane array structure, the outer platform forming an outer peripheral boundary of the flowpath through the vane array structure, the plurality of vanes arranged circumferentially about an axis, each of the plurality of vanes extending radially across the flowpath from the inner platform to the outer platform, the plurality of vanes comprising a first vane, and the first vane comprising a channel and a passage that extends around the channel within the first vane;
- and
- an air particle separator including an input air inlet, a clean air outlet and a waste air outlet, the input air inlet fluidly coupled with the clean air outlet and the waste air outlet, and the waste air outlet fluidly coupled with and configured to direct waste air to the passage.
A method of operation, comprising:
- directing bleed air into a vane of a vane array structure within a turbine engine, wherein the vane extends across a core flowpath within the turbine engine;
- processing the bleed air within the vane to provide clean air and waste air, wherein the waste air includes more debris than the clean air;
- cooling the vane using the waste air;
- and
- directing the clean air into a bearing compartment within the turbine engine.
