Introduction Vertical Wind Turbine Clean Alternative Energy Sustainability Center

Objectives Design an efficient prototype Vertical Wind Turbine Convert kinetic (mechanical) energy electrical energy Design Mechanical Airfoil System with Wind Direction Indicator Produce efficient power source

Components Air Foils - Wind Power Generation Cam System - Controls Air Foil Movement Drive System - Adjusts RPM Electronic System - Controls Wind Turbine Functionality Generator - Conversion to Usable Energy Weather Vane – Specifies Wind Direction to System

Vertical Wind Turbine Initial Design

Airfoil Design Modification Louver System

CAM Design with Displacement Diagram

Shaft Design 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) / 11250 = 1. 414 inch

Drive Design Chain And Sprocket Design No. 80 Chain, 1 inch pitch Length = 100 pitches, 100 inch Chain Center Distance = 30. 26 inch (Maximum) Sprockets = Large, 59 teeth, D = 18. 789 Small, 17 teeth, D = 5. 442 Input RPM @ 3 MPH = 38 RPM (Estimated) Output RPM = 130 Minimum, 2500 Maximum

Cost and Weight Estimations

Determining Reaction Forces on 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 = -R 1 – R 2 +270 lbs+30 lbs Moment of Bending: M(a) = 0 = (270)(1. 5 ft) + (30)(5 ft) - R 2(3 ft) R 2 = (555)/ (3 ft) = 185 lbs. R 1 = 115 lbs.

Goals 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
