In this session we will introduce industry specific applications from the aerospace industry and how Finite Element Analysis (FEA) is used to ensure safe and optimized design of different subsystems. We will learn how to ensure that resonance within the operational frequency range is avoided by performing modal analysis of a drone blade. We also perform modal analyses of a recreational drone and of a lightweight airplane. We wrap up this session by performing stress analyses to optimize the design of a helicopter rotor pitch arm.
