2. Overview Vertical-Axis Wind Turbine Interchangeable Shaft
Savonius Turbine
Interchangeable Shaft

3. Last Week’s Action Items
Define ‘Step Two’
Plan from Raw to Final
Mechanical Components
Finalize circuit logic
Decide on intelligence
Circuit Diagram

4. ‘Step Two’ Step One was receiving parts
Step Three is displaying the final product
Step Two is EVERTHING IN BETWEEN
Fabrication
Assembly

5. ‘Step Two’ Shafts Base Turn to proper size
Install bearings, sprockets, shaft couplings
Machine Flats and Keyways
Align centers
Base
CNC base plates
Mounting for bearings, generator, battery
Seatings for vertical supports and diagonal straps

6. ‘Step Two’ Turbine Hand Crank Machine barrel into blades
Mounting blades to the shaft
Hand Crank
Discuss with Welder
Cut/Drill pieces to make his job easier

7. Circuit Design Circuit Block Diagram
Microcontroller input = current sensor
Decided on ‘slow drain’ circuit
Real circuitry is overly complicated for MEs
Products already available

8. Circuit Design

9. This Week’s Action Items
Finish all machining
Shafts – Matt, Joey, Michael
Baseplate – Domenic, Heather
Turbine – Heather, Matt, Domenic
Hand Crank – Joey, Michael, (Paul)

10. This Week‘s Action Items
Final Documentation Rough Draft
Plan who/how:
Joey will take the lead on writing/organizing
Meet/Discuss to divide up sections and assign work to ‘experts’
Outline as a group
Combine individual efforts into one coherent report

11. Conclusion So close…yet so far away. Show Stopper: Rotating Parts!
Behind:
Waiting for electronic components
We can catch up!
