Initial testing of the current Ambular design shows several aerodynamic issues, the biggest being the negative lift generated by the fuselage and propeller arms. Thus, the current stage of the project focuses on redesigning the fuselage and optimizing the arm shape. First, preliminary research on the different fuselage and airfoil designs were conducted. The information gathered was then used to guide the development of new Ambular components. A few designs were considered for both the fuselage and propeller arms, which were then tested via computational fluid dynamics (CFD) software to determine one best suited for the mission parameters of low-speed flight and long endurance. Development of Extended-Range Unmanned Surface Vehicles (USV) Supervisor: LI Larry / MAE Student: CHONG Long Fung / MAE Course: UROP1100, Spring The potential energy sources for Unmanned Surface Vehicles (USVs) have been investigated. Methods of harvesting energy and its mechanisms are represented in the paper. Wind energy, wave energy and solar energy are the main topics of this research, and these energy mechanisms are analyzed and their performance benchmarked against each other.
