Design and Fabrication of a Multirotor UAV for Heavy-lift Applications

This research delineates the design and execution of an Unmanned Aerial Vehicle (UAV) specifically tailored for heavy-lift applications. A thorough examination of the current literature on UAVs was conducted to guide the selection of cost-effective and efficient components, subsequently leading to a requirements analysis for the delivery UAV to design an appropriate airframe. The properties of the UAV system were modeled utilizing parameters derived from the chosen materials. A power system was engineered to satisfy the energy requirements of the UAV, predicated on a proposed maximum payload of 10 kg. PID tuning was carried out for flight stability using PID Toolbox software. The outcomes of the diverse tests conducted indicate a highly functional and stable prototype for cost-effective heavy-lift applications up to 7kg, and provide access to challenging terrains previously deemed inaccessible by conventional methods.
