2. INTRODUCTION
As the world continues to use up non renewable energy resources,
wind energy will continue to gain popularity. A wind turbine is a type
of turbo-machine that transfers fluid energy to mechanical energy
through the use of blades and a shaft and converts that form of energy
to electricity through the use of a generator.
Wind energy is considered the fastest growing clean energy source.
In today's life the demand on electricity is much higher than that of its
production. In this 21st century there are many methods to produce
energy. In renewable energy field sector, wind turbines play an
important role in energy production A major issue with the technology
is fluctuation in the source of wind.

3. ABSTRACT
 The objective of this project is to generate electric power through the fabrication
of Darrieus wind mill.
 A wind turbine is a machine that converts the kinetic energy in wind into
mechanical energy. If the mechanical energy is used directly by machinery, such
as a pump or grinding stones, the machine is usually called a windmill.
 They can be made many different ways with buckets, paddles, sails, and oil
drums. The Darrieus rotor is H-rotor and All of these designs turn relatively
slowly, but yield a high torque. They can be useful for grinding grain, pumping
water, and many other tasks; but are not good for generating large amounts of
electricity. One might use a gearbox, but then efficiency suffers and the machine
may not start at all easily.
 This project is designed with Wind mill arrangement, Dynamo, and Battery.

4. EXPERIMENTAL SETUP & PROCEDURE
DESIGN OF BLADES
The C-type Darrieus blade profiles are generated with the NACA 0012 profile as
the reference. The design of this unique blade structure is that it is hollow and
exposed at one side, while having the NACA 0012 profile as the cross section has
been showed. The generation of the NACA 0012 profile were done using online
tools (airfoil tools, 2014) and the major dimension

5. Aerofoil Cross Section
An airfoil-shaped body moved through a fluid produces an aerodynamic. The
component of this force perpendicular to the direction of motion is called lift. The
component parallel to the direction of motion is called drag.
The geometry of the airfoil is described with a variety of terms :
 The leading edge is the point at the front of the airfoil that has maximum curvature
(minimum radius).
 The trailing edge is defined similarly as the point of maximum curvature at the rear of
the airfoil.
 The chord line is the straight line connecting leading and trailing edges. The chord
length, or simply chord, is the length of the chord line. That is the reference dimension of
the airfoil section.

10. WORKING PRINCIPLE
 This Darrieus wind turbine designed for air flow sensor, speed sensor, battery voltage
monitoring, dynamo power monitoring, microcontroller, and WIFI used for in IOT
technology.
 The air flow sensor used for atmosphere air velocity measuring purpose. The speed
sensor used for wind speed monitoring purpose. Then voltage measurement used for
battery and dynamo output power monitoring purpose. The microcontroller to send to all
information in WIFI device via server an IOT technology.
 Wind mill arrangement is the mechanical arrangements which are easily rotated. The
rotating speed is depends upon the wind strength. The wind mill arrangement is coupled
with the dynamo. So whenever the wind mill is rotated due to wind, the dynamo also
rotated. The electric power is generated in the dynamo. The generated electric power is
given to battery through the charging circuit.

11. Static Analysis of Rotor
The resultant force (FR ) can be decomposed into both a normal
component, FN and a tangential component, FT . It is this tangential
force component that drives the rotation of the wind turbine and
produces the torque necessary to generate electricity. So calculate the
values as described in above force analysis section and apply these
aerodynamic forces for analysis of the rotor of the turbine.
The wind turbine model draw in the Solid Works software,
corresponding load and fixed constraints applied to the model at the
same time. Three materials chosen for the wind turbine rotor, alloy
steel, aluminum alloy and structural steels were compared and
analyzed.

16. FABRICATION PROCEDURE
 The fabrication of the turbine blade, rotor and support structure are done as per the
manufacturing drawing produced by solid works using structural steel, which
involves various operations like plate cutting, bending to shape, welding, turning,
facing, drilling, assembly and painting etc.
 The turbine blade is made out of 2mm M.S. sheet, which involves various
operations like cutting of sheet as per sheet development of drawing, bending to
the aerofoil shape as per drawing. The turbine blade band is also made out of 2mm
M.S. sheet, which involves operations like cutting of sheet as per sheet
development of drawing, bending to the shape as per drawing.
 The turbine blade arms is made out of 5mm M.S. plate, which involves operations
like cutting of plate as per plate development drawing, bending to the shape and
drilling as per drawing. The rotor shaft is machined in lathe for its desired finished
which involves various operations like turning, facing etc.
