Custom Airfoil
Challenge
- Design a unique airfoil geometry optimized for aerodynamic performance
- Model the airfoil in CAD with a 6-inch chord length for 3D printing
- Conduct wind tunnel testing using pressure measurements along the surface
- Evaluate lift and drag performance across multiple angles of attack to assess efficiency and stability
Approach
- Used a pitot-static tube to measure airspeed in the wind tunnel via total and static pressure differences
- Integrated pressure taps at the stagnation point and multiple locations on the upper and lower airfoil surfaces
- Connected each tap through the hub to a pressure sensor for data acquisition
- Applied a calibration equation to convert measured voltages into pressure values for analysis
Solution
- Showed theory-consistent behavior for the coefficient of lift vs. angle of attack
- Displayed an approximately linear relationship from 0° to 10°, with a peak lift coefficient of 0.46
- Demonstrated a smooth increase in lift without premature stall behavior
- Confirmed a successful airfoil design with stable, reliable, and predictable lift performance within the tested range
