An airfoil is a device that provides reactive force when in motion, relative to the surrounding air. Usually the force created is lift because of the pressure differences over the top and bottom surface. Airfoils have many purposes. They produce lift required to keep an airplane in the air, prevent a race car from lifting off the ground at high speeds, lifts a hydrofoil’s hull outside the water, and many others. By placing a hole in an airfoil I hoped to find a new application for an airfoil.

Most of the time, airfoils are designed to produce the maximum lift yet leave as little drag as possible. Such airfoils are ideal for most applications because an airfoil is used to move an object efficiently, and in a desired direction. However, I thought of a simple idea of how an airfoil could be used for a different purpose. My idea is to place a hole through the airfoil, connecting the upper surface and lower surface. In theory what should happen is during some sort of airflow, air would be sucked through the hole from the bottom and released at the top. Therefore, the velocity of airflow through the hole would be faster than the velocity of the surrounding airflow.
