2. General Airplane Design Overview
Wingspan = 5.0 ft.
Weight = 2.5 lbs.
Wing Area = 4.3 ft.2

3. Design Change – Winglets to Tail
Manufacturing challenges involved
Large area required for winglets
Solution:
Extend fuselage behind wing
Add vertical tail on wing centerline
Keep small winglets for style

4. Class 1 Sizing of Canard & TailLc
Lvt

5. Historical Sizing of Control Surfaces
All surfaces deflect +/- 30 deg
~25-50% of chord
Elevator
~10% of b
~0-20% of canard b/2
~10% of b/2
Rudder
~25-50% of tail chord
~15-25% of chord
Aileron
~40% of wing b/2
~10% of b/2

6. Location of AC

7. Location of CG
SM=15%

8. Dihedral Angle McCombs article
R/C aircraft have dihedral angle from 0°-2°
Basics of R/C Model Aircraft Design Ch. 9
~4° for low wing
Our choice 3°

9. Flight Performance - Takeoff
Vtakeoff= 28 ft/s
Ttakeoff= 2.7 s
Xtakeoff = 53 ft

10. Flight Performance - Turning

11. Flight Performance Endurance Climb Batteries sized based on mission
Need 480 mAh for 8 required endurance
Battery selected provides 640 mAh
Oversized for mission due to limited selection
Climb
Motor / propeller selection based on mission climb requirement

12. Future Considerations
Verify previous AC calculations
Create x-plots
Design yaw damper
Generate inputs for FlatEarth.m
