Abstract
A turbine blade for use in a gas turbine engine includes localized thickening of a neck pocket of the turbine blade to meet strength requirements while minimizing the weight of the turbine blade. More specifically, a convex spline is positioned within a suction side neck pocket of the turbine blade adjacent a leading edge of the neck pocket to increase the strength of the blade.
