Abstract:
Wind energy systems have become a focal point in the research of renewable
energy sources. In this research provides a new concept of high performance, low
cut-in speed wind turbine blade. To design the wind turbine blade, SG6043 airfoil
profile has been chosen and wind tunnel experiments were performed at various
Reynolds numbers. The pressure distribution, Cp, the lift and drag coefficients, CL
and CD, were used for varying angles of attack, a. The conventional wind turbine
blades have performed generally above 2.5ms-1 wind velocity at least. But our
wind turbine blades can rotate well below the usual minimum wind velocity of
2.5 ms-1 and in this lower velocity (<2.5 ms-1 ) we have got the maximum 100 W
power output and voltage of 12V.
