Variable pitch system for UAV proprotors
| Resumo: | Unmanned Aerial Vehicles (UAVs) have gained significant attention in diverse applications, prompting a surge in research and development. Current Vertical Take-Off and Landing (VTOL) UAVs rely on fixed-pitch proprotors which makes them face limitations in performance and maneuverability. This thesis addresses these challenges by proposing the development of a stand-alone Variable Pitch Proprotor (VPP) system capable of real-time pitch adjustments during different flight phases. The research delves into the fundamentals of VTOL flight performance, variable proprotor impact, control subsystems, power management, firmware strategies and short-range wireless communication protocols. Studying and analyzing existing solutions and technologies in these domains is conducted. The subsequent stages involve designing the subsystem architecture, implementing it on a mechanical prototype, and evaluating the system’s performance and limitations in various settings. This Thesis will contribute to enhance UAVs stability, maneuverability, and energy efficiency, towards to the advancement of Urban Air Mobility (UAM). |
