  1. Flapping Wing MAV Group 13 – NASA Ames Parker Cook George Heller Joshua Nguyen Brittney Theis

  2. The Customer • Dr. Shih • Funding to be provided by the NASA Ames facility

  3. The Problem • We are tasked with designing and building a flapping-wing micro aerial vehicle (MAV) that is constrained by certain specifications provided by the customer and inspired by the European Micro Air Vehicle Conference and Flight Competition.

  4. Project Scope and Needs

  5. Original Design • 2 Flapping Wings • Controlled rotation of the wings • The wings use a track to slide back and forth • DC Motor rotating causes the wings to flap

  6. Dragon Fly Inspired • 2 sets of wings in an collapsing/expanding X formation in an up and down movement • Tail rotor • DC Motor rotating • A larger toy

  7. Bird • - Actuated joints in all directions that cause the wings to curve in aiding to the flight Bat • - Fast flapping • - More fixed wing then bird but jointed

  8. Design Inspiration The Delfly inspired design was chosen as our flapping wing MAV because of its ability to meet our customers needs and has the highest probability to fulfill our design criteria and complete all necessary functions.

  9. Gear Train and Wing Mechanism

  10. Tiny Pager Motor by Solarbotics Diameter = 4mm (0.158”) Length = 16.4mm (0.65”) Shaft Diameter = 0.66mm (0.026”) Weight = 1g (.035oz) Motor Selection

  11. Component Selection Great Planes ElectriFly 4Ch FM Rx 72MHz Hitec Eclipse 7 7-Channel FM/4 Futaba FM Receiver Crystal Short R114F 72MHz High

  12. Component Selection • Servos: • Currently, servos scavenged from the E-Flite Microflyer will be used. • Piezo-electrics were researched, but would require more power than we could supply. Battery: 110mAh 1S 3.7V LiPo: BMCX

  13. Wing Material Selection • McMaster Polyester (PET) Film • Thickness: .001“ • Width: 40“ • Length: 10' • Tensile Strength: 28,000 psi • Clear, No Tint, Weather Resistant

  14. “Bones” Material Selection • McMaster Rigid Carbon Fiber Shape Round Tube • OD: .125“ • ID: .074" • Length: 48" • Tensile Strength: 120,000 psi

  15. Conclusion

  16. Future Plans • Find Torque on the Shaft • Resizing • Find appropriate Servos • Finalize Design Calculations • Finalize Manufacturing Plans
