| Abstract | ||
| This study presents an influence of aerodynamic shape of the airfoil of two NACA number,4-series and 5-series.The parameters in the numerical code can be entered into the equations to precisely generate the cross-section of the airfoil and calculate its properties, and study its influence on vibration response of the first five frequencies. Three dimensional model built by ANSYS V11.0 with(solid 45) element,by using FEM to analyze the theoretical , the same amount of lift and drag force at (4 deg.) angle of attack for both series .The results shown an increase at odd freq., and degrees at even one for (NACA 5-series).In the same way nodal solution had been drawn and it was shown that stress value of NACA 5-series is higher at the first three freq | ||
