1. An airfoil comprising:
a shell defining an exterior surface of the airfoil and forming a cavity in an interior surface of the airfoil;
a lattice damper disposed in the cavity, the lattice damper to reduce vibrational loads exerted on the airfoil, the lattice damper including a plurality of unit cells, the plurality of unit cells being cross-cube shaped and hollow with a single continuous surface;
an inlet opening extending through a wall of the shell proximate a leading edge of the airfoil;
an outlet opening extending through the wall of the shell proximate a trailing edge of the airfoil; and
a plurality of channels defined in the lattice damper to fluidly couple the inlet opening to the outlet opening, the inlet opening to receive heated fluid to flow from the leading edge to the trailing edge via the plurality of channels.
