TL;DR: In this paper, a method for repairing damage to an airfoil is described, which provides for the removal of a section of the air-foil that substantially encompasses the damaged area, which consequently leaves a void and a cut-away surface.
Abstract: A method is disclosed for repairing damage to an airfoil. The method provides for the removal of a section of the airfoil that substantially encompasses the damaged area, which consequently leaves a void and a cut-away surface in the airfoil. A replacement piece larger than the residual void is provided for use in replacing the section removed from the airfoil. A joining operation welds or otherwise joins the replacement piece to the airfoil at the cut-away surface to form a joined airfoil. The joined airfoil has a seam between the airfoil and the replacement piece. At least a portion of the seam is processed by laser shock peening to induce compressive residual stresses therein.

TL;DR: In this article, the effect of some design parameters on the performance of a Giromill vertical axis wind turbine has been investigated with varying the design parameters such as, pitch angle, number of blades, airfoil type, turbine radius and its chord length.
