This aim of this senior design project is to investigate the combination of a Selig 1223 and FX 74-CL5-140 into one profile to increase lift without significantly increasing drag. Our project began with researching current solutions for high lift and low drag airfoils. We found two airfoils which would be the target of our research, a Selig 1223 and the FX 74-CL5-140. After learning about the Cl and Cd of the current airfoils we built and physically tested the airfoils using additive manufacturing. A pressure differential tunnel was used to validate the airfoils. After researching how to blend two airfoil profiles together, our version of a blended wing was 3D printed. We used the same wind tunnel to test our experimental airfoil. Overall, the blended wing has shown an approximately 6% increase in lift. Drag was not found due to problems in the axial force sensor of the wind tunnel.
