11. An airfoil assembly comprising:
an airfoil body defining a leading edge cavity defined between a leading edge of the airfoil body and an interior rib, wherein one or more aft cavities are defined aft of the interior rib, and having a forward radially extending rail and an aft radially extending rail formed on an inner surface of the airfoil body that defines the leading edge cavity; and
a baffle installed within the leading edge cavity, the baffle comprising:
a baffle body defining a feed cavity within an interior thereof, the baffle body extending between an outer diameter end and an inner diameter end;
a forward standoff shelf formed along an exterior surface of the baffle body, the forward standoff shelf defined by a depression, bend, or channel in a material of the baffle body extending from the outer diameter end to the inner diameter end and configured to engage with the forward radially extending rail; and
an aft standoff shelf formed along an exterior surface of the baffle body, the aft standoff shelf defined by a depression, bend, or channel in the material of the baffle body extending from the outer diameter end to the inner diameter end and configured to engage with the aft radially extending rail,
wherein a surface of the baffle body between the forward standoff shelf and the aft standoff shelf defines a side channel surface extending in a radial direction along the baffle body between the outer diameter end and the inner diameter end, and
wherein the baffle body comprises an aft wall having at least one trailing edge impingement aperture formed thereon, wherein the at least one trailing edge impingement aperture is configured to direct an impinging flow against the interior rib during use.
