Abstract
This paper is an exploration of how the effects of wing geometry on the lift and drag in both air and water. The purpose of these findings is to understand if there exists a foil geometry that would offer the best lift-drag ratio in both fluids. To find the answer, chamber, chord, span, and aspect ratio were adjusted in an attempt to maximize lift and drag. The calculations were done through Matlab and the results are shown through Matlab figures. The Matlab code created shows that symmetric airfoils have the greatest lift to drag ratios due to their lower drag and relatively high lift. Cambered foils create higher lift at the cost of higher drag, reducing the lift-drag ratio. It is further found that aspect ratio has the greatest effect over lift-drag ratios. To maximize lift and minimize drag, aspect ratio should be as high as possible.
