3. 12/13/2003By: Strobridge & Sulkoski3 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.

4. 12/13/2003By: Strobridge & Sulkoski4 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.

5. 12/13/2003By: Strobridge & Sulkoski5 Solution  Hub on generator for blade mounting Will accept various blades with a standard rod  Students will be given standard dowels (for example) to make their blades with  Controlled wind rotor with variable direction & blade pitch Generator hub assembly will be on a stand that will be controlled by a motor Blade pitch will either be manually adjustable or electronically controlled

6. 12/13/2003By: Strobridge & Sulkoski6 Solution  Variable wind speed Controlled by HC08 & anemometer feedback  The anemometer will communicate the wind speed to the user  The HC08 will vary the frequency to the fan to change the speed until the desired wind speed is met  Data Acquisition Card For importing power output & wind speed to computer program  Preferably an external card for Plug & Play interface with various computers  Computer program with user interface Lets user control the variables of the system & gather the preferred data

8. 12/13/2003By: Strobridge & Sulkoski8 Milestones  Design for the hub assembly How to attach the blades How to adjust the blades pitch  Wind speed Varying the speed of the Tubeaxial Fan’s AC motor Getting the anemometer to talk to the HC08 to set the speed of the motor  Mobility Making the unit mobile and easy to move  If on wheels the unit will require brakes to overcome the force from the fan to keep it stationary

9. 12/13/2003By: Strobridge & Sulkoski9 Budget  Parts & Materials  Funded by Prof. Kidder Not to exceed $4000  From Alternative Energy Grant
