Abstract
An airfoil comprises an external surface formed in substantial conformance with a plurality of cross sections. Each of the cross sections has an axial chord and an offset at a corresponding fractional span as set forth in Table 1. Each of the cross sections is described by a set of Cartesian coordinates defined at the corresponding fractional span as set forth in Table 3.

An airfoil comprising:
- an external surface formed in substantial conformance with a plurality of cross sections of the airfoil, each of the cross sections having an axial chord and an offset at a corresponding fractional span as set forth in Table 1;
- wherein each of the cross sections is described by a set of Cartesian coordinates defined at the corresponding fractional span as set forth in Table 3.
A vane comprising:
- an airfoil formed in substantial conformance with a plurality of cross sections defining an external surface of the vane;
- and
- a platform attached to a root section of the airfoil;
- wherein each of the cross sections has an axial chord and an offset at a corresponding fractional span as set forth in Table 1;
- and
- wherein each of the cross sections is described by a set of Cartesian coordinates defined at the corresponding fractional span as set forth in Table 3.
