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.

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

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

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
