Abstract
Official abstract text for this publication.
An airfoil is disclosed herein. The airfoil may include a leading edge, a trailing edge, a suction side defined between the leading edge and the trailing edge, and a pressure side defined between the leading edge and the trailing edge opposite the suction side. The pressure side may include a concave profile about the trailing edge that varies from a profile of a remainder of the pressure side.
First claim
Opening claim text (preview).
That which is claimed: 1. A method for improved flow turning and lift in an axial compressor, comprising: starting with an airfoil as depicted in FIG. 2 , wherein the airfoil comprising a leading edge, a trailing edge, a suction side defined between the leading edge and the trailing edge, and a pressure side defined between the leading edge and the trailing edge opposite the suction side; and modifying the pressure side about the trailing edge to from a concave profile about the trailing edge that varies from a profile of a remainder of the pressure side as denoted by a transition point without modifying the suction side, which modifies a thickness distribution about the trailing edge, which in turn modifies an effective camber of the airfoil to increase an effective camber of the airfoil without modifying the suction side.
