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
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.
