WIND TURBINE DESIGN REPORT
1. ABSTRACT
Now a days Renewable power era can assist international locations meet their
sustainable development dreams by imparting an get secure, clean, dependable and
low cost energy. As the Renewable energy have gain more importance, due to large
amount of power generation capacity today by renewable sources. The Renewable
energy industry having a worth of thousands of billions dollars because of hundreds
of gigawatts and megawatts renewable plants such as wind, hydropower and solar
plants are being installed in the whole world every year. As the wind is evolve due
to the multiple heating impacts on the Earth’s surroundings with an aid of sun , the
abnormal geometry may used as a source of renewable energy. Due to the low cost
of operational and due to the fact that this is a clean source of energy, the wind
energy will becomes one of the most relevant method of producing electric power
in distinct places. So this report is used to design and analysis of wind turbine. So
this report consider the wind data of the different places to calculate the wind
speed which will act on the turbine blades.
2. INTRODUCTION
Wind turbines are now widely used in hilly areas and rural plane areas which is used
to generated electricity with the help of wind. As is renewable source of energy so
obtain from nature in abundant form. The blades on wind turbine are rotated by
wind strikes on the surface of turbine blades. The turbine blades mounted on shaft
which is coupled with gearbox and generator(dynamo) .In gearbox, the multiple
gears are coupled in such a way that output shaft get required speed in terms of
rpm. Shaft from the gearbox is coupled with generator where the electric power is
produced from the rotational motion of shaft.

WIND TURBINE DESIGN REPORT
COMPONENTS
All the major parts of wind turbine is shown below
1) Blades
The blades are the most important part of turbine as power generation is totally
depend on the shape and size of wind blades. Here the around 180 mm curved
blades are designed for minor losses and maximum efficiency.
Manufacturing process :-
The blades can be manufactured from the casting process. As initially a mould cavity
of the blades shape is prepared then the molten metal is poured into mould and
allow to cool down then remove the mould then obtain the blades of desired shape.
Material used :- AISI 304 (Stainless steel)
Major properties is shown below.
Elastic Modulus 1.9e+011 N/m^2
Poisson's Ratio 0.29 N/A
Shear Modulus 7.5e+010 N/m^2
Mass Density 8000 kg/m^3
Tensile Strength 517017000 N/m^2
Yield Strength 206807000 N/m^2
Thermal Conductivity 16 W/(m·K)
Specific Heat 500 J/(kg·K)
