Abstract
A turbine bucket dovetail secures buckets in a turbine rotor. The turbine bucket dovetail includes a plurality of hooks engageable with a wheel post of the turbine rotor, which hooks extend in an axial direction relative to the turbine rotor. A pocket is machined in a tangential face of the dovetail, resulting in reduced peak stress in the wheel post dovetail edge at the gate opening.
