PROBLEM TO BE SOLVED: To provide an airfoil assembly.SOLUTION: An airfoil assembly (44) comprises: at least one airfoil (50) having a leading edge (51) and a trailing edge (52); a band (60, 80) 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 trailing edge (52) of the at least one airfoil (50), the relief (72) 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 an airflow through the relief (72).SELECTED DRAWING: Figure 1 |
