    Abstract: An apparatus and method for an engine component having a working airflow separated into a cooling airflow and a combustion airflow, the engine component comprising a plurality of circumferentially spaced airfoils rotatable about a centerline defining an axial direction, each airfoil comprising an outer wall bounding an interior and defining a pressure side and a suction side extending between a leading edge and a trailing edge to define a chord-wise direction and extending between a root and a tip along a span-wise direction to define a span length; wherein each of the airfoils have an unguided turning angle to stagger angle ratio defined with respect to a percentage of the span length.

    Abstract: A blade includes an airfoil body defined by a concave pressure side outer wall and a convex suction side outer wall that connect along a leading edge and a trailing edge. The blade also includes a first corrugated surface extending from the trailing edge to the leading edge on an outer surface of the concave pressure side outer wall, and/or a second corrugated surface extending from the trailing edge to the leading edge on an outer surface of the convex suction side outer wall. The blade acts to reduce flow velocity losses associated with wake mixing by accelerating the mixing process from the source of the wake to minimize inflated unsteady mixing that occurs within a downstream blade row.

    Abstract: A vane for a turbomachine includes a pressure surface and a suction surface opposite the pressure surface. The pressure surface and the suction surface define a width therebetween. The vane also includes a first end. The first end includes a distal portion, a proximal portion, a pressure surface first portion, and a suction surface first portion. At least one of the pressure surface first portion and the suction surface first portion slope away from the other of the pressure surface first portion and the suction surface first portion such that the width increases from a first end minimum width at the proximal portion to a first end maximum width at the distal portion.
