1. Revolutionary Technologies Group C1 Nicholas Arch, Nicholas Fraser, Robert Huth, Patrick Noble, Michael Toomey Preliminary Design Review March 20, 2008

2. Last Week’s Action Items  Complete CAD model Add internal components to the base cylinder Show how the main shaft attaches to the system Display placement of guide lines which secure the wind turbine to the ground Describe in detail the blade setup  Finalize the blade manufacturing method Analyze vacuum forming plastic  Have to create mold and it is potentially expensive Bending of sheet metal  Heavy and not easily broken down or carried

3. Current Status of Concept Status of Design Beginning to manufacture the base unit, the blade mold, and start designing the electronics system Focus on: cost weight size

4. Blade Assembly

5. Main Shaft Assembly

6. Twist Plate Assembly

7. Fixed Plate Assembly

8. Gear and Generator Assembly

10. Twist and Lock Feature

11. Next Week’s Action Items  Shaft Assembly Huth will attach bearings to the main shaft Arch will attach the gear to the main shaft Leon will assist in attaching load supports to keep shaft in place  CNC Plates for base unit Fraser will generate CNC file for plates Toomey will generate CNC file for brackets Both will utilize the CNC end mill to fabricate  Begin Electronics work Noble will begin constructing the electronics layout
