An Experimental Study to the Repairing of the Damaged Airfoils

This article investigates the aerodynamic characteristics of repairing the airfoil with circle damage shape & star damage shape by the measurement of the aerodynamic coefficients improvement. For study of these models, applied method is used a full span NACA 64-412 airfoil. Using model for experimental solution is in five schematics: undamaged, damaged model with upper, lower, and full repair model. The used repair sheets are chosen based on the ABDR manuals. Effect of the repair on different shape of damage has performed.
