A quadcopter is a multi-rotor-type helicopter that is lifted and propelled by four propellers. These propellers were driven by four DC motors. The difference in angular speeds of propellers is responsible for roll, pitch, and yaw motions. Nowadays, research in the field of unmanned aerial vehicles (UAV) is increasing because of their interesting applications. During the flight of a quadcopter, the propellers are subjected to thrust forces and vibrations. The main objective of this study is to find out the natural failure frequency of a propeller and the best-suited material which can sustain the loading and vibration during the flight. The CAD model of a propeller is designed in Creo 2.0 design software, and ANSYS 16.2 is used to analyze the vibration frequency. In this paper, the propeller is subjected to a thrust force of 50 N. Furthermore, modal analysis has been performed to find out the resonance frequency under pre-stressed condition. The obtained simulation results are validated with the previous works in the existing literature.
