Abstract:
A compressor airfoil has a leading edge, a trailing edge, and a radially outboard edge connecting the leading edge and the trailing edge. The leading edge is formed according to a leading edge tip profile and the trailing edge is formed according to a trailing edge tip profile. The leading edge tip profile and/or trailing edge tip profile has a chamfer and/or a radius. In this manner, contact stress experienced by the compressor airfoil such as upon contact with a surrounding abradable seal are ameliorated. The leading edge tip profile and/or trailing edge tip profile are coated with an abrasive coating such as to enhance fitting of the abradable seal to the path of the compressor airfoil upon such contact.
