The Study of the Effect of Wing Shapes on Their Drag and Lift Coefficients

Overview

Objectives/Goals Through the testing of different cross-sectional airfoil shapes, an ideal wing shape can be found that can be used to optimize the aerodynamic advantage of airplanes today, the new technology being designed to produce more lift while reducing drag. Methods/Materials Wind Tunnel: 20x20, 3100 CFM [cubic feet per minute] floor fan with reverse blow; 8x8x16 in. rectangular plastic enclosure; 2 # 16 in. long plastic funnel shape with 8x8 in. squared small end; 1/8 in. thick polycarbonate plastic material; 5 boxes of straws. Styrofoam, Aluminum Foil, 48 in. long, ¼ in. diameter plastic rod, Any 40 g base, rounded, Spring Scale - increments of 1 oz., Weight measure, Smoke machine, Silicon Adhesive, Scissors, String, Sand Paper.
