TURBINE BLADE AIRFOIL PROFILE

A turbine blade (28a) for a gas turbine engine has an airfoil (50) including leading (54) and trailing edges (56) joined by spaced-apart pressure and suction sides to provide an exterior airfoil surface extending from a platform (58) in a spanwise direction to a tip (60). The external airfoil surfac...

Beschreibung
Zusammenfassung:	A turbine blade (28a) for a gas turbine engine has an airfoil (50) including leading (54) and trailing edges (56) joined by spaced-apart pressure and suction sides to provide an exterior airfoil surface extending from a platform (58) in a spanwise direction to a tip (60). The external airfoil surface is formed in substantial conformance with multiple crosssectional profiles of the airfoil (50) described by a set of Cartesian coordinates set forth in Table 1, the Cartesian coordinates provided by an axial coordinate scaled by a local axial chord, a circumferential coordinate scaled by a local axial chord, and a span location.
