2. 04/26/04By: Strobridge & Sulkoski2 Agenda  Background  Problem & Solution  System Components Mechanical Electrical Software  Budget

3. 04/26/04By: Strobridge & Sulkoski3 Background  System used for educational purpose.  A fan is used to provide airflow for the testing of small wind rotors.  Old system was insufficient & inadequate. Consisted of:  Lego Generator & LEDs to measure power output.  The tunnel was a box shape made out of scrap material. Old Tunnel

4. 04/26/04By: Strobridge & Sulkoski4 Problem Design & build a wind rotor testing system.  Capable of testing wind rotors up to a 20 inch diameter.  Automated, so the user can obtain measurements of rotor power output to wind speed graphically.

5. 04/26/04By: Strobridge & Sulkoski5 Solution  Hub on generator for blade mounting  Variable blade pitch  Variable wind speed  Data Acquisition Card  Computer program with user interface
