Unmanned Aerial Vehicle (UAV) is unpiloted aircraft that can be remote controlled or fly autonomously based on pre-programmed flight plans or more complex dynamic automation systems. One of the critical parts in developing an UAV is the structural dynamic analysis on the structure itself. This project is undertaken with specific objective which is to do dynamic analysis onto the designed micro UAV structure. During the progress to complete the project, information gathered from all reliable sources including the properties of the materials involved, the suitable method in producing the dynamic analysis, and others. After the reviews of the literature being completed, the project methodology will be developed. In the methodology, the best suitable method will be implemented to do the analysis, and in this case, Newtonian method was chosen. In this project, Acrylonitrile butadiene styrene (ABS) had been considered to be the structure material. For the first step in project methodology, mathematical modelling will be developed. Using data and sources gathered, then, analysis will be done to determine the structure’s mode shapes and response. After the calculation was completed, the results gained will then being compared and validated by referring to the existed journals and articles about the structural dynamics. Based on the analytical method, the designed structure was achieved to sustain such wind load applied on it by the fans. Referring to the analysis done, the main objectives of this project were achieved. As to enhance more of the analysis and the research study, other method such as Hamilton Principle, Rayleigh method and Finite Element method should be used in the methodology stage, and perhaps, they will give better results and more precise analysis in the project development.
