  13. Preliminary Layout

  14. Motor Specifications • Himax HA2025-4200 Geared Electric Brushless Inrunner • Lightweight • High efficiency • High torque • Durable • Specs: • Power: 175W • KV: 4200 • Gear Ratios: 6.6:1, 5.3:1, 4.4:1 • ESC Rating: 15A • Weight: 80g • Shaft Diameter: 3mm

  15. Motor and Prop Table

  16. ELECTRONICS & CONTROLS Batteries Selection Note: Toxicity in reference to the two types of batteries mentioned above. • NiMH best candidate based on Energy Density and NiCd’s Memory Effect; Li-Po not allowed • Competition Requirement: 20A ATO Blade Fuse

  17. ELECTRONICS & CONTROLS Battery Selection • Cell packs • Offer range of Capacity, Weight and Cost • Fixed dimensions • Individual Cells • Offer more versatility in weight, size and cost • Requires soldering

  18. ELECTRONICS & CONTROLS Controllers Selection • Servo Controller Requirements • Programmable for Fail-Safe Maneuver • Support for 4 Servos, 1 Gyroscope • Micro Maestro 6-ch USB Servo ($19) • ESC Requirements • ESC Continuous Amp higher than Motor ESC Rating • Programmable; Can control at least 1 Motor • Propulsion Battery Pack limited to 0.75lbs

  19. Electronics & Controls Transmitter /Receiver • Spektrum DX6i 6-channel transmitter. • Transmits on 2.4GHz band • Practically safe from internal and external Radio Frequency (RF) • AR6200 6-channel receiver. • Combined internal and external receiver • Safe RF linking

  20. Electronics & Controls Sensors • Gyroscopes – Device measuring orientation, based on the principles of conservation of angular momentum. • Accelerometer – A device that measures proper acceleration relative to freefall. • None – A situation in which no stabilizing instrument would be used.

  21. Electronics & Controls

  22. Electronics & Controls Software • Integrated Debugging Environment (IDE) – Microsoft Visual Studio 2010 • Allows programming in C language • Already accustomed to the software • Free of charge • Radio Fail-Safe Maneuver • Kill Throttle • Roll Right • Yaw Right • Nose Up

  23. Wing Design

  24. Wing Sizing • Assumptions • Empty weight = 1.25 lbs • Payload/Weight Ratio = 3:1 • Launch Speed = 22 MPH • Derived dimensions • Wing Area = 336 in2 • Wingspan = 48 in • Chord Length = 7 in • Aspect Ratio = 6.85

  25. Fuselage Front View Top View

  26. Interim Design

  27. Future Work • December 1 • Fabricate Interim Design • December 1, 2010 – January 1, 2011 • Test and refine • Iterate • Competition: April 15-17, 2011
