The document summarizes a student project presentation on designing a wind-powered car. It includes the names of the presenting students and their professor. It then discusses the concept of using wind turbines and transmission mechanisms like gears to convert wind energy to mechanical energy to power the car. Diagrams show the planned vehicle design and powertrain layout. Calculations are included to analyze the power generated by the wind turbines at different speeds and how it compares to the power consumption of the car. The document concludes with discussions of results and the scope for further improvements to the design.

3. 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.

4. 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.

5. 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.

6. • 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 .

7. 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 .

8. 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 .

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

10. 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.

11. Project overview
• GEOMERTY OF VEHICLE

12. Side View

13. • 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.

14. How power Transmitted

15. 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

16. • 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.

17. 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.

18. 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.
• Fig. Bevel gear geometry

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

21. Calculation
At 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 = 𝜋/4*D² = 𝜋/4*.030² = 0.0706 m²
• 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

22. • 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.
