    • An attachment system (10) for a turbine airfoil (12) including one or more roots (14) to attach the turbine airfoil (12) to a rotor is disclosed, whereby the roots (14) have teeth (20) configured with bearing surfaces positioned at different angles (42, 48, 62, 74, 92, 96, 104, 120) to increase the low cycle fatigue life of the root (14). As such, the low cycle fatigue life of a first side, first axially extending tooth (38) may be not more than 10 percent different than low cycle fatigue life of a first side, second axially extending tooth (46) to achieve balanced low cycle fatigue life and stress concentrations between the radially outer bearing surfaces (28) of the first side, first and second axially extending teeth. Such relationship increases the useful life of the airfoil (12). Other teeth (20) on the root (14) may have a similar relationship. The attachment system (10) may include compound fillet (22) between each set of adjacent teeth (20) and other elements to increase the useful life of the airfoil (12).
