Abstract
An airfoil assembly may include a shroud and an airfoil. The shroud may include a first attachment arm, a second attachment arm, and a shroud rail extending from a first surface of the shroud. A first channel may be defined between the first attachment arm, the first surface, and the shroud rail and a second channel may be defined between the second attachment arm, the first surface, and the shroud rail. The airfoil may extend from a second surface of the shroud opposite the first surface. In various embodiments, a height of the shroud rail, as measured from the first surface of the shroud, is non-uniform.
