1. A body part comprising:
- a surface having a fluid flow thereover;
flocking coupled to at least a portion of said surface that adjusts an aerodynamic characteristic relative to said surface that is devoid of said flocking; and
at least a portion of an airfoil having said surface wherein said aerodynamic characteristic includes lift and said flocking is coupled to at least said portion of said surface to increase said lift produced by said airfoil for a predetermined range of angle of attack.
