Abstract
An airfoil is disclosed. The airfoil may comprise a body portion having a leading edge, a trailing edge, a pressure side, and a suction side. The airfoil may further comprise a compliant attachment bonded to the body portion and the compliant attachment may be configured to connect to a support structure. The compliant attachment may have a coefficient of thermal expansion intermediate between a coefficient of the thermal expansion of the body portion of the airfoil and a coefficient of thermal expansion of the support structure.
