Preliminary design of multirotor UAVs with tilted-rotors for improved disturbance rejection capability

The ability of multirotor UAVs to hold position accurately in a turbulent wind environment is important for a variety of commercial applications. In this work, a tilted-rotor configuration which offers the potential for improved disturbance rejection capability over traditional multirotor designs is presented, along with a design process to select optimal design parameters and components for a particular payload and hover time. The design process integrates models of UAV components and performance based off manufacturer data, and is applied to a range of payloads to explore resulting designs and trends. From the components considered used in this work, the tilted-rotor concept is found to provide the most benefit at payloads under 10 kg, and negligible benefit at payloads above 12 kg.
