Improving the economy and performance of an aircraft requires careful consideration of aerodynamic properties and weight reduction in the wing construction process. The design is mostly determined by the material and profile type of the aerofoil. The goal of this project is to determine the natural frequencies of the NACA 4412 aerofoil profile blade. The light-weight composite materials used to create the NACA 4412 are carbon fibre, Al-Zn-Mg alloy, and alpha-beta titanium alloy. It is observed that vibrations increase as the frequency is increased in all modes, and that there is an optimal frequency at which the vibrations in the various modes of vibration are at their lowest. After importing the SOLIDWORKS-developed model into ANSYS Workbench, the necessary parameters were entered to perform the modal analysis. The study's goal is to determine which material—carbon fibre, alpha-beta titanium alloy, or al-zinc-magnesium alloy—will be able to endure frequencies of NACA 4412.
