Abstract A team consisting of five members conducted an experiment dealing with fluid flow of an airfoil and the forces that act on the airfoil as the fluid flows over it. In order to complete the experiment the team used a Clark Y-14 Airfoil and a wind tunnel. After running the experiment and doing the calculations it can seen that the results of the experiment where not very useable, but it can be said that the experiment was sufficient in showing how lift is created in an airfoil.
