This article investigates the aerodynamic characteristics of repairing the airfoil with triangular damage by the measurement of aerodynamic coefficients improvement. For study of this model “two applied and numerical methods are used”. A full span NACA 641-412 airfoil is considered as test model. Using model is in five schematics: undamaged model, 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 by the quantity and quality results.
