Abstract
A compressor flowpath includes circumferentially spaced apart airfoils having axially spaced apart leading and trailing edges and radially spaced apart outer and inner ends. An outer wall bridges the airfoil outer ends, and an inner wall bridges the inner ends. One of the walls includes a flute adjacent the leading edges for locally increasing flow area thereat.
