In aviation, wings and blades play a major role for flight control. The helicopter rotor blade in both the symmetric and asymmetric airfoil type usingCATIAsoftware, Composite materials are widely opted in manufacturingindustry because of high strength to weight ratio, hence carbon epoxy and boroepoxy are chosen for the design consideration and also it is compared with aluminum material and using ANSYS software package, the static strength and the dynamic characteristics will be analyzed in three modes. The high stressed area is identified in the von misses stress technique. The analysis is carried out in the symmetric and asymmetric airfoil separately by altering the material and the results are compared for the better solution. Thus resonance in rotor can be avoided by using the proper selection of
material by calculating the natural frequency.
