The Purpose of this project was to test and find the best Airfoil with the greatest lift, drag ratio for our airfoil glider (link below). I made a printed airfoil from inventor, and carved and sanded down an foam airfoil. After that I tested the airfoils in the air tunnel, and calculated the lift/drag ratios.
The next three pictures below are my, plastic airfoil that I created from inventor, test results from air tunnel with 0 degrees angle, and test results with 20 degrees angle.
The next three pictures below are my, foam airfoil that I sanded down and carved out, test results from air tunnel with 0 degrees angle, and test results with 20 degrees angle.
This is the lift drag ratios that I calculated from the test results from the graphs of the airfoil lift and drag in the wind tunnel.
