Design Mechanical Airfoil System with Wind Direction Indicator

Produce efficient power source

Objectives

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

Components

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) / 11250 = 1.414 inch

Shaft 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

Approximate Weights for Vertical Wind Turbine Component Weight (lbs) Vehicle Axle (Shaft) 100 DC -540 Low Wind Permanent Magnet Alternator 11 Sprockets and Chain 15 Louvers 100 CAM System 25 Bearings 4 Relay Box 3 Approximate Total Weight 258 lbs

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
