Selectively thinned turbine blade

A turbine blade (16) includes an airfoil (18), platform (20), shank (22), and dovetail (24). The platform (20) includes a first side (46) disposed along the pressure side (32) of the airfoil (18), and an opposite second side (48) disposed along the airfoil suction side (34). The platform second side...

Beschreibung
Zusammenfassung:	A turbine blade (16) includes an airfoil (18), platform (20), shank (22), and dovetail (24). The platform (20) includes a first side (46) disposed along the pressure side (32) of the airfoil (18), and an opposite second side (48) disposed along the airfoil suction side (34). The platform second side (48) includes an integral damper keeper (50) disposed below the midchord of the airfoil (18), and is locally thinner at the forward and aft ends of the platform second side (48) for reducing blade weight.
