At low power wind turbines blade end is free. The paper shows the
negative influences of finite span on performance profiles. It is made a critical
analysis of application Prandtl model for finite span wing at low power wind
turbines. The paper introduces a new method for calculating certain
adjustments based on Prandtl model.
