Aerodynamics PDR #1

This project examines airfoil and wing shape choices in aerospace design, focusing on aerodynamics, manufacturability, and structural concerns. It analyzes historical data, NASG Airfoil Database, and wing shapes with considerations for manufacturing ease, drag and lift performance, and structural integrity.

  1. Aerodynamics PDR #1

  2. Objective • To examine airfoil choices • To examine wing shape choices • Structural and Manufacturing Concerns

  3. Airfoil Selection • Manufacturability • Short building time and inexperience requires simple manufacturing • Aerodynamics • Low Cd • High L/D • High Clmax • Structure • Thin airfoil selection may not allow for sufficient structure (< 10%) • Method • Historical Data • NASG Airfoil Database

  4. Airfoil Analysis – Selig Airfoils All data from NASG airfoil database http://www.nasg.com

  5. Raw Wind Tunnel Data

  6. S1210 Geometry

  7. Elliptical Twist Taper Sweep Hard to build; unless use foam Time consuming to build Wing Shapes

  8. Aspect Ratio Sizing High AR decreases Cdi High AR produces small chord length at given area Small chord produces small thickness Building concerns Structure concerns Wing Shapes

  9. Use a rectangular wing with no twist, taper or sweep Easy to build Taper, sweep, and twist effects will most likely not be worth the difficulty of manufacturing Wing Selection • Aspect Ratio Sizing • AR between 5 and 7 • Area about 10.9 feet2 • From constraints and weight of 6 lbf • Chord about 1.5 feet • Reduced structural and manufacturing concerns • Span about 8.0 feet • Portability as two piece wing

  10. Vertical and Horizontal Tail • Flat Plate • Easy Manufacturing • Easy Analysis (Drag & Lift) • Easy Modeling (Controls & Feedback) • Sizing complete by Aerodynamics PDR#2
