System having blade segment with curved mounting geometry

Garcia-Crespo, Andres Jose; Noble, Patrick Daniel

Title: System having blade segment with curved mounting geometry

Abstract

A system includes a blade segment having a blade and a mounting segment coupled to the blade. Additionally, the mounting segment includes a first contact face and a second contact face, wherein the first and second contact face are concave with respect to a longitudinal axis of the blade segment. To reduce stresses within the mounting segment, the mounting segment further includes a lower face coupling the first contact face and the second contact face, wherein the lower face is convex across the longitudinal axis of the blade segment.
