Claim 0:
1. An airfoil assembly defining a span axis, a root end, and a tip end, the airfoil assembly comprising:
a reinforcement structure comprising a first helical support structure fully wrapped around the span axis between the root end and the tip end and a second helical support structure fully wrapped around the span axis between the root end and the tip end, wherein the first helical support structure defines a first wire diameter and the second helical support structure defines a second wire diameter, and wherein at least one of the first wire diameter or the second wire diameter varies along the span axis;
a polymeric matrix material positioned at least partially around the reinforcement structure; and
an outer skin positioned around the reinforcement structure and the polymeric matrix material.
