  1. Revolutionary Technologies Group C1 Nicholas Arch, Nicholas Fraser, Robert Huth, Patrick Noble, Michael Toomey Preliminary Design Review February 7, 2008

  2. Last Week’s Action Items • Decide between horizontal-axis and vertical-axis wind turbine • Options: Lift-Based Vertical, Drag-Based Vertical, Traditional Horizontal • Calculate power and torque • Use literature from Dr. Nelson • Complete torque calculations for available generators • Analyze generator specifications • Explore back-driven DC motor • Calculate required torque using given generator

  3. Vertical vs. Horizontal • Simplicity vs. Efficiency • Drag vs. Lift based designs • Varying wind conditions • Immediate weather response

  4. Generator Selection • Basic torque requirement calculations • Generator vs. DC motor • Generator is designed for constant power • Motor is designed for torque

  5. Torque Calculations

  6. Current Status of Concept Status of Design Researching to decide best HAWT design Focus on: blade geometry shaft geometry wind shield counter rotating blades

  7. Next Week’s Action Items • Individual Trade Study Proposal • Finalize trade study assignments • Perform Research to select design variables and tools to be used in the trade study • Complete Certification on tools • Michael Toomey will get CNC certified • Rob Huth will get Mill and Lathe certified

  8. Thank You Questions?
