Laminar air flow. (Junior Division).

The purpose of this project was to determine the ease of laminar air flow around four different air foils made of balsa wood. A wind tunnel made of PVC pipe, a digital balance, and a vacuum was also constructed to test the air foils at the same laminar flow velocity. The balance determined the amount of drag of each air foil in the wind tunnel. Five trials were performed and data was graphed to compare amount of drag of each air foil. It was concluded that the teardrop-shaped air foil proved to have the least drag and showed lift, while the eye-shaped air foil had the most drag. The diamond-shape and oval-shaped air foil proved to have intermediate drag results, compared to the teardrop and eye-shaped air foils.
