2. 02/10/2004By: 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. 02/10/2004By: 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. 02/10/2004By: Strobridge & Sulkoski4 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

5. 02/10/2004By: Strobridge & Sulkoski5 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

13. 02/10/2004By: Strobridge & Sulkoski13 Mitered, 90 Degree Elbow

14. 02/10/2004By: Strobridge & Sulkoski14 Choices  Transitioning Square to Round   = 30 , L = 11.2”, Co = 0.20 Round to Square   = 30 , L = 11.2”, Co = 1.20  Turning Smooth Radius with Splitter Vane  r = 2’, Cp = 0.05

15. 02/10/2004By: Strobridge & Sulkoski15 Milestones  Design for the hub assembly Optional, seen as a last item of importance by customer  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  Possibility of calibration to cut out the anemometer  Mobility Not requested, unit will have a permanent home  Unit will still be able to be disassembled and reassembled in a different location
