CONSIDERATIONS ABOUT POWER INCREASING AND
NOISE REDUCTION FOR LOW POWER WIND TURBINES
WITH TURBINE BLADE WITH A WINGLET
The low power wind turbines are being designated for locations that
have as a characteristic a moderate wind regime. These are placed in the
proximity of human habitation, where is necesary to reduce the aerodynamic
noise. Adding a winglet bended towards upstream side to the existing blade
increase the force distribution on the blade and increase the produced power.
The winglet bended towards downstream side reduces the aerodynamic noise.
