I really enjoyed the whole process of my EE especially when an accurate graph was generated, which matched the predicted model very well. I have considered other research questions to explore. Instead of only looking at the effects of angles of attack on the lift-to-drag ratio, I could have looked for the perfect geometrical shape of the airfoil that is most efficient through altering chamber thickness, chord length, or even twisting angle. This was actually my original idea and it would provide results that were more complex and might have more applications. However, the current research question is still more appropriate due to the fact that there is not a single shape of airfoil that is “perfect”: when one aspect of airfoil is optimized, other properties might be influenced. The current research question ensures the simplicity of independent and dependent variables, which maximizes the probability of yielding results that are persistent and replicable. During the data collection, the significance of the stall effect actually surprised me: once past the stall angle, the originally joined airflow suddenly splits so completely that I can easily feel the difference. Overall, I am satisfied with the whole EE process and have learned a lot.
