  1. UAV Wing Design For Efficiency At Low Reynolds Numbers Presented by Devin Jensen Embry-Riddle Aeronautical University

  2. Wing Design Overview • 2D optimization • 3D optimization • Control • Lessons Learned

  3. Wing Design • 2D Optimization • Airfoil chosen from Selig and Eppler airfoils • Sellig 4110 chosen • High Cl/Cd • Acceptable pitching moment

  4. Wing Design • 3D Optimization • Estimated weight of 8 lbs. • Wanted 10 lbs. of lift • Analyzed a series of wing geometries • Calculated lift and drag

  5. Wing Design • 3D Optimization • Continued • Wing geometry description for chosen wing • Aspect Ratio = 6 • Taper Ratio = 0.5 • C/4 sweep = 0 • Planform Area = 7.5 square feet

  6. Wing Design • Control • 20 percent of wing area for horizontal tail • 10 percent of wing area for horizontal tail • Ailerons, rudder and elevator used for control

  7. Wing Design • Lessons Learned • V-Tail • Flaps • Greater tail area • More dihedral • Pod attachment • Addition of incidence angle
