에어포일 및 에어포일을 가진 기계의 다양한 실시예가 개시된다. 에어포일은 더 두꺼운 리딩 에어포일부 및 더 얇은 트레일링 에어포일부를 포함한다. 한 실시예에서, 리딩 에어포일부는 에어포일의 본체를 자신을 향해 다시 구부림으로써 형성된다. 다른 실시예에서, 리딩 에어포일부는 단단한 형상을 가지고, 두 개의 타원 표면을 포함한다. 공기흐름의 박리를 예방하기 위해, 리딩 에어포일부는 두께가 변화하는 지역에서 형성할 수 있는 볼텍스를 안정화시키는 방식으로 공기흐름을 트레일링 에어포일부로 지향시키기 위해 작동하는 적어도 두 개의 아크부 또는 표면을 포함한다.

    Various embodiments of an airfoil and machines with airfoils are disclosed. The airfoils include a thicker leading airfoil portion and a thinner trailing airfoil portion. In one embodiment, the leading airfoil portion is formed by bending a body of the airfoil back toward itself. In another embodiment, the leading airfoil portion has a solid geometry and includes two elliptic surfaces. To prevent detachment of airflow, the leading airfoil portion includes at least two arc portions or surfaces that act to direct the airflow down to the trailing airfoil portion in a manner that stabilizes vortexes that may form in the region of changing thickness.
