Wind power car

The wind powered car that converts wind power to Mechanical energy which in turn moves the vehicle.

The wind power, which is converted into mechanical energy through gears, belts or chains, causes the vehicle to propel forward.

Wind is one of the prominent sources of renewable energy.

Conti…It is possible that wind could become one part of a

portfolio of alternative energy resources that could someday replace more traditional coal, natural gas and oil electricity plants.

That is reason we are going to make car which is running by wind energy totally and to save fuel as well as environment pollution controlling, there is no smoke and no dangerous gas produce by car exhaust.

One of wind power’s great advantages is that, as a local, renewable, and non-polluting.

Literature survey

WHEN THE CAR RUN To get the most out of the smallest surface we have to use a turbine with a large contact surface. Such turbine will have only one active side.

wind energy processing mechanics in wind powered card wind turbines and Turbine is connect to gear shaft , power transmitted so on.

• Why Do Wind Turbine Blades Move in the Wind?• Newton’s Third Law • There is action of the wind pushing air against the

blade causes the reaction blade being deflection, or pushed .

• Blade are set an angle wind will deflected at opposite angle pushing the blade away from deflected .

Bernoulli’s effect

• Wind blade are shaped so that air molecule moving around the blade travel faster on the downward side of blade then those moving across the up side of the blade .

• Bernoulli’s effect tells us that faster moving air has lower pressure .

• Downwind – difference in pressure on the opposite side of the blade causes the blade to lifted toward the curve of air foil

• Air foil- shaped body moves through a fluid produce an aerodynamics force .

Aerodynamics force

• The lift on an airfoil is primarily the result of its angle of attack and the shape known as aerodynamics force.

• Aerodynamics force resolve in two component –

1.lift – component of this force perpendicular to the direction of motion is called lift .

• Drag- component of this force parallel to the direction of motion is called drag force .

Need of project

It can use as a alternate power source of car.

It can use in wind-zone as power for drive the car.

The ever-intensifying drive to discover clean, renewable energy technologies has in recent years led to developments beyond the lab and the drawing room and into the real world.

Project overview• GEOMERTY OF VEHICLE

Side View

• Mechanism of project • Wind-powered mechanical vehicles primarily

use wind turbines installed at a strategic point of the vehicle. The wind power, which is converted into mechanical energy through gears, belts or chains, causes the vehicle to propel forward. Propel is connect to differentials gear and then connect to wheel shaft that rotate wheel.

How power Transmitted

Design of Blade of WIND Turbine

• Why wind turbine blades moves in the wind • - 1. Newton's third law of action reaction law• -2.Bernoullie effect

• Most of blade angle is positive angle of attack to genrate lift .

• Turning of the air in the vanity of the air foil create curved stream lines which is result in lower pressure on one side and higher pressure at other side.

Gear • A gear is a rotating machine  part having cut teeth,

which mesh with another toothed part to transmit torque , in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear .

• Geared devices can change the speed, torque, and direction of a power source . The most common situation is for a gear to mesh with another gear .

• When two gears mesh, and one gear is bigger than the other (even though the size of the teeth must match), a mechanical advantage is produced, with the rotational speed  and the torques of the two gears differing in an inverse relationship.

Bevel gear

• Bevel gears are gears where the axes of the two shafts intersect and the tooth bearing faces of the gears themselves are conically shaped.

Bearing

• A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts moving parts.

CalculationAt Velocity 15km⁄h

• (15*1000)⁄(3600)=4.16m⁄sec• Total force = Total Drag force+Total Roll force • A = Frontal Area• Cd = Cofficient of drag force.• E = Kinetic Energy (J) ρ = Density (kg/m3)• m = Mass (kg) v = Wind Speed (m/s) • P = Power (W) t = time (s)• D= Diameter of blade = 300 mm• Area of blade = /4*D² = /4*.030² = 0.0706 m²𝜋 𝜋• The kinetic energy of an object having mass m and velocity v is equal to the

work done w is displacing that object from rest to a distance s under a force • E =W = Fs • According to Newton’s Law, we have:• F = ma

• kinetic energy of a mass in motions is:• E = 1⁄2mv²• Power = ½*ρAv3.• Drag Force = • = ½*1.2*0.0706*0.30*4.166² = 0.201 N• Froll = cr m g • Cr = coefficient of rolling resistance, dimensionless (0.0015 to 0.015)• m = total mass of the vehicle with driver in kg• g = acceleration due to gravity 9.81 m/s²• Fr = 0.0015*25*9.81 = 0.3678 N• Total force = Total Drag force+Total Roll force = 0.201N+0.3678N• = 0.5688N• Power consumed by car = (drag force +rolling force)*velocity of car = 0.5688*4.166 =2.36 Watt • Power generated by wind = ½*ρAv3. =1/2*1.2*0.0706*4.166³

=3.049 Watt.
