Nowadays, with regard to the new methods of simulation, the designof airfoils have greatly changed and this allows the evaluation of the effect of various factors on the efficacy of airfoils. Thus, choosing the type of wing would be so important; in another term, designing a proper wing is what an airplane designer is mainly concerned with. In this project, the effect of airfoil wave surface on the changes of coefficients of lift and drag are studied. Graphs of lift and drag coefficients, Cantor Distribution Pressure and Cantor Distribution speed are alsoinspected in different attack angles. The achieved results indicate that wavy airfoils atspecific attack angle and also near the angle of extinction have a better performance than airfoils without wavy surface. The results of airfoil performance in different attack angles shown throughgraphs indicate the proper performance of wavy wing.
