  3. Background • According to DARPA, a Micro Air Vehicle (MAV) has a maximum linear dimension of 6 inches. • Primarily being researched for surveillance and reconnaissance operations. • Other possible uses include forest fire detection, Bio- Chemical detection, etc. • Annual MAV competition where various teams compete in surveillance missions and flight performance tests. RIT MAV Team Project 05-001 2004-2005

  4. Design Objectives • Vehicle with a minimum linear dimension of 15 inches • Vehicle can be scaled down in size and still produce acceptable flight • Vehicle must be a new design, not rely on last year’s design • Airframe should be built out of composite materials if deemed reasonable • Vehicle must have GPS navigation capabilities along with video surveillance • Performance Goals – 15 Minutes of flight time – 600 Meter range • Attend International MAV Competition in Seoul, Korea • Remain within $3,000 budget (excluding travel funding) RIT MAV Team Project 05-001 2004-2005

  14. Airframe - Composition • Balsa Wood with Canvas • Foam (Polystyrene) • Foam with Single Fiberglass Layer • Carbon Fiber • Carbon Fiber with Lightening Holes • Composite (Kevlar, Fiberglass) • Foam and Fiberglass Combination will be Used for Testing, Composition of Final MAV Airframe Still to be Determined RIT MAV Team Project 05-001 2004-2005

  15. Airframe – Pod Location • Mounted Above Wing • Mounted Below Wing • Between Bi-Wing • Suspended Below Wing • Most Likely Design: Mounted Below Wing RIT MAV Team Project 05-001 2004-2005

  16. Airframe – Control Surfaces • Options Considered – Vertical Tail (and Elevator) • Single (High or Low Orientation Possible) • Double (High or Low Orientation Possible) • Angled Vertical Tail – Winglets • Vertical Winglets • Angled Winglets – Canards – Elevators – Ailerons – Elevons • Current Approach: V-Tail Protruding from Pod, Extending Beneath Wing. Elevator to be Integrated if Necessary RIT MAV Team Project 05-001 2004-2005

  17. Future Analysis • Test Airfoils • Control Surface Sizing and Location • Airframe Prototype (March 14 th ) • Refine Design • Evaluate and Test Radical Ideas RIT MAV Team Project 05-001 2004-2005

  20. Components • Onboard RF Controller/Receiver • Onboard Speed Controller • Onboard Servos (Actuators) • Onboard Video System – Video Transceiver & Camera • Passive Antenna Array • Onboard GPS System – Onboard GPS Receiver – Onboard GPS Video Overlay Board • Batteries RIT MAV Team Project 05-001 2004-2005

  21. Onboard RF Controller/Receiver • RF Controller Selected: – Futaba 6YGE 72 MHz RF Controller • Onboard RF Receiver Selected: – GWS NARO R-6NH/V Receiver • Channels: 6 • Size: 20 x 30 x 9.5 (mm) • Weight: 8.8 g We selected the GWS NARO R-6N receiver due to its 6 channel design. This allowed for improvements in the form of additional onboard feature/control devices. Compatibility of the controller/receiver has been verified since both use the Futaba data transmission format.

  22. Onboard Speed Controller • Onboard Speed Controller Selected: – Phoenix-10 The Phoenix-10 speed controller is the leading candidate to be chosen due to its compatibility with the DC motor that is being recommended by the propulsion subgroup. RIT MAV Team Project 05-001 2004-2005
