Aerodynamic efficiency enhancement for asymmetric profiles

Aerodynamic efficiency enhancement for asymmetric profiles

This paper presents a solution for enhancement of aerodynamic efficiency for asymmetric airfoils. In order to increase the lift and reduce the drag forces for a blade segment, a groove was created on its surface. There were carried out experiments consisting in the analysis of two asymmetric airfoil...
