摘要： An airfoil (102), a fan assembly and an engine include at least one airfoil (102) including a root portion (106), a body portion (105) and a tip portion (118). The body portion (105) is configured extending radially outward from the root portion (106) and the tip portion (118) is configured extending radially outward from the root portion (106) and the body portion (105). The airfoil (102) including a suction and a pressure side coupled together at a leading and a trailing edge and extending therebetween. The airfoil (102) including a compliant tip (120) at the tip portion (118). The compliant tip (120) extending along at least a portion of the tip portion (118) in a chord-wise direction and a span-wise direction. The compliant tip (120) is configured to provide wave propagation along the tip portion (118) such that critical strain proximate the tip portion and the trailing edge is reduced during a foreign object impact.
