1. Group 3 Heavy Lift Cargo Plane William Gerboth, Jonathan Landis, Scott Munro, Harold Pahlck October 8, 2009

2. Introduction The team chose to compete in the Regular Class of the SAE Aero East Competition Team must design and build an airplane to lift the most weight All design and construction must be done by the students without professional help

3. Objectives Design and build an airplane to successfully compete in the SAE Aero East Competition Plane must take off from within a 200 foot runway and then land successfully on a runway of 400 feet Constraints of 55 total pounds and a height, weight, and length of 200 inches must be followed

4. Impact UAVs are becoming more prevalent in the military Project will provide model for future UAV production A design maximizing lift will allow for a better performing aircraft

5. Airfoil Concepts Optimal Properties: Maximize Lift, Minimize Drag Researched a variety of airfoil designs Decided on four concepts based on their high coefficients of lift and low coefficients of drag: Eppler 423, Selig 1223, NACA 8414, Wortmann FX 63-137 Obtained values for C L and C D vs. AoA using airfoil modeling software

6. Airfoil Concepts (cont.) Airfoils measured in five categories Each category weighted according to importance Airfoils rated in all categories Weighted composite of scores is totaled Most points = Best airfoil for our needs

7. Wing Shape Concepts Three possible wing positions Straight, Dihedral, Swept Each shape gives unique control, stability and lift characteristics

8. Wing Shape Concepts (cont.) Wing shapes measured in four categories Metrics – Lift, Ease of Construction, Stability, Proven Success in past competitions Lift and Stability of primary concern

9. Landing Gear Concepts 3 Concepts: Tail Dragger, Tricycle, Retractable Compared the weight, cost, durability, aerodynamics, ease of takeoff, and ease of landing

10. Tail Concepts Four Different arraignments analyzed –T-Tail –Cruciform –H-tail –V-tail Four categories the tail arraignments are analyzed for are, drag, ease of construction, stability, ground clearance

11. Tail Concept (cont.)

12. Deliverables Airplane design Metrics used in concept selections Detailed calculations SOLIDWORKS/ANSYS models Budget for the project Analysis of design

13. Budget Expected Budget for Plane Total: $3,474

14. Project Schedule

15. Conclusion Create a competitive airplane design following the rules of the competition Use multiple resources to analyze design Create and follow a clearly defined project management schedule Create an airplane with better capabilities than previous Steven’s designs
