2. Introduction Wind Turbine Project • Jared Freyer (Project Leader, Webmaster) • Senior, Mechanical Engineering • Fahad Ahmad (Recruitment Officer) • Sophomore, Mechanical Engineering • Anthony Christie • Freshman, Engineering • Yuanhua Cheng • Freshman, Engineering 2 BGI

3. Project History Wind Turbine Project • Created by Purdue BGI Club • Developed to create a wind turbine feasibility study prarieroots.files.wordpress.com 3 BGI

4. University Need Wind Turbine Project • Promote the sustainability and need for wind power in Indiana • Using the wind turbine as a living laboratory • Possibilities • Design new/efficient turbine blades • Design new/efficient turbine engines • Study wind/weather on Purdue’s campus • Provide power to the intramural field lights and feed power back into the Purdue power grid 4 BGI

5. Goals of the Project Wind Turbine Project • Get approval from Capitol Projects Council to allow a wind turbine to be constructed • Fundraise money to construct a wind turbine on campus • Make an educational component to go with the wind turbine 5 BGI

6. Past Work (Spring 2009) Wind Turbine Project • Did Initial Planning • Researched Optimal Location for Turbine • Researched Optimal Class of Turbine 6 BGI

7. Location Requirements Wind Turbine Project • Height • Height of turbine and crane for installation restricted to 756 ft above sea level • Due to FAR Part 77 • Structure may not be more than 150 ft above airport elevation • Purdue Airport sits at 606 ft above sea level • Electrical Tie-ins • Duke Energy lines west of McCormick Rd • Purdue power lines east of McCormick Rd • Wind Quality • Determine where the most consistent wind power can be found • Generally related to topography of region 7 BGI

8. 8 BGI

9. Site of Interest Wind Turbine Project • Planned installation near the intramural fields • Site is close to the northwest substation • In close proximity to Purdue power lines • Higher elevation than surrounding area • Highly visible to Purdue students • Proximity to campus would allow for easier educational access 9 BGI

14. Turbine Selection Wind Turbine Project • Large Wind (≥ 1 MW) • Due to siting restrictions large turbines will not be possible • Medium Wind (50 kW to 500 kW) • More feasible with height restrictions • Less efficient than large wind • Small Wind (1.5 kW to 50 kW) • Much less efficient than larger sizes • Less attention demanded 14 BGI

15. Current Work (Fall 2009) Wind Turbine Project • Finalized Decision on Turbine Selection • Calculated Local Average Wind Speeds • Presented Proposal to ALDP • Submitted CPC-1 Paperwork 15 BGI

16. Turbine Selection Wind Turbine Project 16 BGI

17. Redriven 20 kW Wind Turbine Project • Power output • 20 kW rated power output @ 25 mph • 240 V /60 hz / 1 Phase • Features • 79 ft tall tower • 20 ft long blades • 61 dB at a distance of 25 feet • Self-erecting • Electric Yaw Controller • Dynamic Brake System www.energyeducation.tx.gov www.redriven.ca 17 BGI
