碩士 === 逢甲大學 === 航太與系統工程學系 === 106 === In this thesis, the Computational Fluid Dynamics (CFD) is used to simulate the dual-rotor flow field of the UAV, which is used to analyze the aerodynamic performance and engine power required by different parameters. The ANSYS Workbench was used as a tool to develop a multi-rotor UAV with the Industrial Technology Research Institute (ITRI). Firstly, based on different airfoil blades, a dual rotor model and mesh is built in the ANSYS Geometry, and the boundary conditions are established by Setup in CFX, therefore aerodynamic performance and motor power analysis of dual-rotor can be analyzed. Secondly, optimize the several parameters of dual-rotor for different heights and center distances to achieve high performance, and use the ANSYS MODAL to calculate the natural frequency and critical speed of the blade to avoid damage caused by the drone resonance.
