Abstract: ADAPTIVE NOISE-REDUCING LIGHTWEIGHT TOROIDAL PROPELLER FOR HIGH-EFFICIENCY UAV'S Abstract. The present invention relates to an adaptive toroidal propeller system for unmanned aerial vehicles (UAVs), designed to enhance aerodynamic efficiency, reduce noise emission, and improve flight performance. The propeller comprises a continuous ring-shaped (toroidal) blade structure configured to minimize tip vortices and ensure uniform lift distribution. The system further incorporates an adaptive morphing mechanism capable of dynamically adjusting blade curvature and pitch in response to real-time flight parameters, including velocity, altitude, and payload. A sensor-based control unit is integrated to monitor operating conditions and actuate the morphing mechanism, thereby optimizing thrust generation and reducing energy consumption. Additionally, the propeller structure includes lightweight composite materials and an acoustic dampening layer to enhance structural integrity while minimizing noise levels. The invention provides a scalable and retrofit-compatible solution for various UAV platforms, offering improved endurance, stability, and suitability for noise-sensitive applications such as urban surveillance, delivery systems, and precision agriculture.
