Abstract
A blade outer air seal segment may comprise a radially outward surface and a radially inward surface oriented away from the radially outward surface. A cooling channel may be located between the radially outward surface and the radially inward surface. An inlet orifice may be fluidly coupled to the cooling channel. A stress-relief orifice may be between the inlet orifice and the cooling channel.
