Abstract: This disclosure describes a cooling enhancement for gas turbine engine outer air seals. The invention provides heat transfer using impingement cooling and convective cooling through the use of tortuous cooling air passages, and film effective film cooling through the use of cooling air discharge slots that are oriented so as to discharge coolant into the working fluid flowpath with a minimum of momentum exchange between the cooling air and the working fluid.

Abstract: The seal comprises arcuate seal segments extending circumferentially about the flow path, each segment spaced radially outward from the turbine blades. Each seal segment includes an arcuate sealing surface having a first end, a second end opposite the first end, and a radius of curvature equal to the distance between the sealing surface and the axis. There is a supply surface opposite and in spaced relation to the sealing surface and having cooling orifices. There is a first end surface extending along the entire first end, and a second end surface extending along the entire second end. The first and second end surfaces extend from the sealing surface to the supply surface. Each of the first and second end surfaces includes a planar perpendicular surface and a planar canted surface intersecting at an included angle of between 100 degrees and 140 degrees. Each canted surface is canted in the first direction.
