SNUBBER SHROUD CONFIGURATIONS

Abstract:

A blade including an airfoil including a platform, concave pressure sidewall and a convex suction sidewall extending axially between corresponding leading and trailing edges and radially between a root and an outboard tip. The blade further includes an angled outboard snubber shroud positioned on the airfoil, the angled outboard snubber shroud being provided at an angle .alpha. defined from a camber on the angled outboard snubber shroud and the platform of the blade; an angled inboard snubber shroud positioned on the airfoil, the angled inboard snubber shroud being provided at an angle .PHI. defined from a camber on the angled inboard snubber shroud and the platform of the blade. The angle .alpha. is independently set with respect to angle 4.
