Abstract

The wind energy is the one of the
renewable energy which helps in extracting
the current by making it to rotate. In our
concept we had a design consideration that
the slot is made in the wing where the
impact of the air is more, in this the air is
allowed is pass through the wing hollow
section and make it to accelerate through the
tip, so that the rotation of the blade will be
more in order that it will produce more
output. Advances in turbine blade design
technology are required to make wind a
viable large-scale producer of electricity.
Blades need to become lighter, stronger,
more efficient, and cheaper. This will allow
turbines to withstand stronger wind, produce
more power, and become economically
competitive with coal or nuclear electricity
production. Our proposed concept of
accelerated wind turbine comes under the
category of upwind turbine. According to
the statistical analysis of low speed winds
around the area the power is theoretically
calculated with the available data, three
rotor horizontal axis wind turbine is
constructed. The turbine blade is made up of
light weight material supported with internal
structure made up of light weight, high
strength and with standing wind loads upto
desired limit. The blade shape is of airfoil
design (MH104).the selected airfoil design
of the blade will have an altered design of
MH104 on the upper chamber .on the upper
chamber 20% of blade length from root, 1/4
of chord length from leading edge of the
blade the hole in a rectangular arrangement
on the upper chamber will allow the impact
of air to flow into the blade from root to tip.
Before the tip, at the trailing edge the flow is
exhausted. This results in acceleration for
the blade. Comparing to the normal blade
configuration this proposed configuration
will reduce the weight and also increases the
mass flow rate of air flow on and inside the
airfoil, also by the acceleration of air at the
trailing edge of blade tip
