Vertical Wind Turbine Initial Design

Airfoil Design Modification Louver System

CAM Design with Displacement Diagram

 We will use a Vehicle Axle for the shaft that is attached to the Air Foils and driving sprocket.  Length = 92 in, Diameter = 3 in  Required shaft Diameter (D) = Sqrt[2.94 (Kt*V*N) / Sn’] Kt = Stress Factor, V= Shear Force, N = Max Stress Component  D = Sqrt[2.94(2*10.58*361.43) / = inch Shaft Design

 Chain And Sprocket Design  No. 80 Chain, 1 inch pitch  Length = 100 pitches, 100 inch Chain  Center Distance = inch (Maximum)  Sprockets = Large, 59 teeth, D =  Small, 17 teeth, D =  Input 3 MPH = 38 RPM (Estimated)  Output RPM = 130 Minimum, 2500 Maximum Drive Design

COMSOL Model

Cost and Weight Estimations

 Platform – 3 ft. for components ; 2 ft. overhang for alternator, chain, shaft and sprocket  Forces in x-direction: F(x) = 0  Forces in y-direction: F (y) = 0 = -R1 – R2 +270lbs+30lbs  Moment of Bending: M(a) = 0 = (270)(1.5ft) + (30)(5ft) - R2(3ft) R2 = (555)/ (3ft) = 185 lbs. R1 = 115 lbs. Determining Reaction Forces on Platform

 To design a potentially more efficient prototype vertical wind turbine  Capable of withstanding 130+ mph winds  Continuous adjustment to the wind direction for maximum performance  Design of a fail-safe system for extreme, harsh conditions  Supplemental teaching resource for future engineering students Goals
