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

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

Class 1 Sizing of Canard & Tail Lc Lvt

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 These drawings are not to scale

Location of AC

Location of CG SM=15%

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°

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

Flight Performance - Turning

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

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