2 Overview Introduction Design Budget Schedule Issues Conclusion Questions

3 Introduction Design a device that generates electricity using wind power at high elevations Capitalize on increased wind speed at higher elevation

4 Design Requirements –100 Watt power output –No rigid structural support –Operate at elevations greater than 100ft –Transportable with a full-size pickup truck –Zero safety-related incidents –Total cost not to exceed $12000 CDN

5 Alternatives Cups of Wind Aerofoil VAWT

6 Wind Eagle Design advantages –Relative simplicity –High component efficiency Four major components –Kite –Turbine and frame –Tether & electrical line –Ground equipment

7 Kite Component Requirements – At least 40 lb of lift –High flight stability –Low weight to reduce size

8 Kite Flat Plate Analysis Performed –Laminar flow, no skin drag –Lift = –Drag = 19 ft Delta Kite chosen –15 km/h: 36 lb lift –20 km/h: 64 lb lift Courtesy of

9 Turbine and Frame Component Requirements –100W power output in 20 km/h winds –Low weight –Physical size –Turbine brake –Turbine blade guard –Self-adjusting to wind direction

10 Turbine and Frame 24V AirX 403 Wind Turbine –400 Watts in 45 km/h winds Electromechanical brake –Activated from ground via switch Aluminum frame –Built around turbine –Vane & flex legs –Estimated weight = 20 lbs

11 Tether and Electrical Line Component Requirements –Low weight –Small diameter –High strength –Minimal power loss

12 Tether and Electrical Line Synthetic Fiber Rope –750 lb load limit –0.13 lb/100 ft –1.75 mm dia. Electrical Cable –14 AWG 3-phase –13% power loss 100 Watts 300 ft of cable Courtesy of

13 Ground Equipment Component Requirements –Easily transported –High speed retrieval –Load capacity with SF > 3 –Power monitoring & energy storage –Radio controller

14 Ground Equipment Manual winch –Steel construction –1:1, 2:1, & 1:2 gear ratios –Band brake Electrical –Batteries –Multimeters –Switch

15 Ground Equipment Input torque –1:1 ratio T = 125lb*1/3 ft = 42 ft-lb –2:1 ratio T = 21 ft-lb Main shaft bending stress –2 pillow block bearings σ = 63,800 psi –4 pillow block bearings σ = 9,100 psi
