A turbine blade for a gas turbine engine. The turbine blade having a plurality of cooling holes defined therein, at least some of the plurality of cooling holes being located on a suction side of an airfoil of the turbine blade and in fluid communication with an internal cavity of the turbine blade; and wherein the at least some of the plurality of cooling holes are located in the airfoil according to the coordinates of Tables 1 and/or 2.

A nozzle segment for a gas turbine engine includes an arcuate outer vane platform segment. An arcuate inner vane platform segment spaced from the arcuate outer vane platform segment. A multiple of airfoils between the arcuate inner vane platform segment and the arcuate outer vane platform segment, the arcuate outer vane platform segment includes a scallop slot and a seal that seals the scallop slot.

A stator vane for a gas turbine engine includes a first platform and a second platform radially spaced apart from one another. The first and second airfoils are circumferentially spaced from one another and interconnect the first and second platforms. The first platform has a gas path side facing the airfoils and a non-gas path side opposite the gas path side. A circumferentially extending rail provided on the first platform extends radially outward from the gas path side to the non-gas path side to form a pocket on the non-gas path side between the first platform and the rail. A reinforcement is arranged in the pocket and joins the first platform and the rail. The reinforcement includes a variable thickness in the circumferential direction and is arranged generally centrally between the first and second airfoils.
