Title: Wavy airfoil

Abstract: This invention uses a novel shape of airfoil to achieve an improved lift to drag ratio and to improve performance at higher angles of attack. The airfoil has a three dimensional wave pattern that modifies the shape of a traditional airfoil to coordinate the airflow through channels on both the top and bottom sides. The uniquely shaped airfoil of this invention could have many uses including a wind turbine blade. This invention not only provides for a more efficient device by improving the effective angle of attack and lift/drag ratio, but also provides for a quiet airflow thus greatly reducing nuisance noise over conventional devices.
