Abstract
An attachment root of an airfoil is provided. The attachment root may comprise a serration profile, a symmetry plane bisecting the serration profile, and a line perpendicular to the symmetry plane. A first lobe of the serration profile may have a first contact face angled 135 degrees from the line. A second lobe of the serration profile may have a second contact face angled 135 degrees from the line. A third lobe of the serration profile may have a third contact face angled 135 degrees from the line.
