Device Design Turbine made out of 12 ga. aluminum sheeting Base and stand are wood Plexiglas generator and pulleys Rubber O-ring for belt Shafts are 1/8” Stainless Steel Tig Rod
Mechanics • Angled blades to increase rotation • 2 to 1 ratio pulley system • 400 ft. of copper magnet wire • 4 magnets
Efficiency Theoretical Power P= Power in Watts ρ= Air density (kg/m3) A= Area of fan exposed to wind v= Velocity of wind (m/s) Actual Power I= Current (amps) V=voltage Efficiency
Design/Construction Issues • First design had horizontal turbine • Support problems • Belt for pulley system • Attachment of generator to base • Materials for pulleys
Conclusions • It was fun and educational! • Implementation of previously learned knowledge • Rotational kinetic energy- pulley system • Conservation of energy • Project success • Stronger magnets and more wire coils • Great Team!
