An airfoil assembly 44 comprising at least one airfoil 50 having a leading edge 51 and a trailing edge 52, a band 60, 80 and rigidly coupled to the at least one airfoil 50 along a portion of an interface 70 between the band 60, 80 and the at least one airfoil 50 for providing at least a portion of support for the at least one airfoil 50, a relief 72 located in the band 60, 80 at the leading edge 51 or the trailing edge 52 of the at least one airfoil 50 and defining a stress relief gap 74 between the band 60, 80 and the leading edge 51 or trailing edge 52 and a closure 76 preventing airflow through the relief 72. |
