Abstract:
1. A compressor component comprising: an attachment; an airfoil extending radially outward from the attachment, the airfoil having a leading edge and a trailing edge with the trailing edge spaced a distance from the leading edge and separated by concave and convex surfaces, the airfoil having a thickness between the concave surface and convex surface wherein the thickness varies non-linearly along an airfoil span, as measured in a radial direction from the attachment to an airfoil tip; wherein the thickness at approximately 15%-25% along the airfoil span is greater than the thickness at approximately 35% along the airfoil span and the thickness at least approximately 40%-80% along the airfoil span is greater than the thickness at approximately 15-25% along the airfoil span.
