  • Publication number: 20070269313
    Abstract: A turbomachinery blade having a relief hole in its platform and a method of limiting the formation and/or propagation of cracks in the trailing edge of the blade are provided. The relief hole may be formed in the concave side of the platform proximate the trailing edge along its mean camber line. The relief hole may be circular in cross-section and is blind, i.e., does not exit on any other face of the platform. The relief hole prevents the formation of cracks in the trailing edge of the blade and also slows the propagation of any cracks which may have formed in this region of the blade.
