摘要： A slotted turbine static nozzle airfoil. In one embodiment, the turbine static nozzle airfoil includes a concave pressure wall having a slot extending therethrough; a convex suction wall adjoined with the concave pressure wall at respective end joints; and a pocket fluidly connected with the slot and located between the convex suction wall and the concave pressure wall, wherein at least one of the convex suction wall or the concave pressure wall includes a thinned segment proximate one of the respective end joints, the thinned segment configured to extend the pocket toward a trailing edge of the turbine static nozzle airfoil.
