1. An airfoil, comprising:
an inner wall and an outer wall, the outer wall spaced apart from the inner wall in a radial direction, a space between the inner and outer walls defining a flow passage; and
a body positioned between the inner and outer walls, the body traversing the inner and outer walls in an axial direction, the body attached to an inner surface of the outer wall via a first ligament and an outer surface of the inner wall via a second ligament, the body detachable from the inner and outer surfaces and to at least partially seal the flow passage, the outer wall movable relative to the inner wall.
