“Design and build an unmanned aerial vehicle (UAV) capable of performing realistic autonomous missions in an aviation environment.” Objective
Mission Profile • Autonomous or manual takeoff • Autonomously navigate through specified waypoints (if manual takeoff, demonstrate transition to autonomous flight) • Dynamic re-tasking of aircraft during flight • Provide imagery, total number of targets, GPS coordinates, and target orientation • Autonomous or manual landing within a specified area
Competition Restrictions • Ceiling: 500ft AGL • Floor: 50ft AGL • No-fly zones • Max Weight: 55lbs • Max Mission Time: 40min
The Airplane • Material Comparison • Fabrication • Dimensions • Weight • Components • Performance • Longitudinal Stability and Control
Composites • Advantages • Strength • Durability • Ease of Fabrication • Disadvantages • Expensive • Can be heavy for small aircraft Material Comparison
Balsa • Advantages • Light Weight • Relatively Inexpensive • Disadvantages • Complex Structural Design • Length of Fabrication Time Material Comparison, Cont.
Method • Wet-layup • Hotwire Foam Materials • Materials • Fiberglass/epoxy • Carbon Tubes • Owens-Corning “Pink” Foam • Plywood Fabrication Technique
Wing • Airfoil Section: SD7062 • Chord: 16in • Span: 106in • Area: 1696in2 • Aspect Ratio: 6.5 • Fuselage • Length: 40in • Length (Tip to Tail): 80in • Width: 8.5in • Height: 8.5in Airplane Dimensions
Empennage • Horizontal • Airfoil: NACA 0009 • Span: 34in • Chord (Root): 11.3in • Chord (Tip): 5.6 • Area: 287.3 in2 • Aspect Ratio: 4.02 • Vertical • Airfoil: NACA 0009 • Height: 16in • Chord (Root): 15in • Chord (Tip): 7.5in • Area: 180 in2 Airplane Dimensions, Cont.
Gross Weight: 35.73 Empty Weight: 34.6 • Airframe: 25 • Systems: 9.6 Fuel Weight: 1.13 Airplane & Systems Weight(All Weights in pounds)
Engine • Fuji BT-64A Gasoline Engine • Fuel Tank • 24 oz • Propeller • 20in diameter X 10in pitch • Radio Control • Futaba 9-Channel Transmitter/Receiver Airplane Components
Recovery Parachute • Drag Chute Airplane Components, Cont.
Minimum Required Power: 0.37 hp • Velocity at PR,min: 28.9 mph • CDO: 0.047 • VSTALL: 27 mph • VCruise: 45 mph for PReq: 0.82 hp • Vmax: 97 mph Performance Analysis
Longitudinal Stability and Control • C.G at 24 inches from Nose (1/4 Chord of Wing) • Distance from Neutral Point to Nose is 27.2 inches • Static Margin is 19.8% • Cm-alpha = -0.963 radians-1
Contingency Plan • Rugged Design • Chute System • Camera Transmission Failsafe Modes • COTS Parts for quick replacement
Progress Update • Airframe Design 90% Complete Partial Construction Underway • Systems Hardware and Power Systems Complete Software Programming and Testing Underway
Conclusion • Durable • Future Usability • Fulfils all Mission Specifications • Upgradeable
