2. 04/13/2004By: Strobridge & Sulkoski2 Background  System used for educational purpose.  A fan is used to provide airflow for the testing of small wind rotors.  Current system is insufficient & inadequate. Consists of:  Lego Generator & LEDs to measure power output.  The channel tube is a box shape made out of scrap material.

3. 04/13/2004By: Strobridge & Sulkoski3 Problem Design & build a wind rotor testing system.  Capable of testing wind rotors up to 30 cm in diameter.  Automated, so the user can obtain measurements of rotor power output to wind speed.

4. 04/13/2004By: Strobridge & Sulkoski4 Solution  Hub on generator for blade mounting  Variable blade pitch  Variable wind speed  Data Acquisition Card  Computer program with user interface
