ABSTRACT:
The present invention discloses a turbomachinery blading configuration. The configuration includes a circumferential recess in a blade support structure and a plurality of blades. Each blade has a platform for mounting the blade within the recess. Each platform includes oppositely directed, generally circumferentially facing edges, each edge having a first and second axial surfaces separated by a recess. The surfaces contact matching surfaces on adjacent blades thereby determining predictable load paths for tangential and twisting moment reaction forces acting on the blades.
