Abstract: Unmanned Aerial Vehicles (UAVs) have become integral to various applications, yet their operational efficiency and noise emission remain critical challenges. This project focuses on the aerodynamic analysis and optimization of noiseless UAV propeller designs using Computational Fluid Dynamics (CFD). By leveraging advanced CFD simulations, we assess the airflow characteristics, thrust generation, and acoustic behavior of different propeller configurations. The study aims to reduce aerodynamic noise while maintaining or enhancing propulsive efficiency. Design modifications, including blade geometry refinement and tip treatments, are evaluated to identify optimal configurations that balance performance with acoustic stealth. The results provide actionable insights into developing quieter UAV systems suitable for sensitive missions and urban environments, where noise reduction is essential. This research contributes to the growing demand for UAVs that are both aerodynamically efficient and environmentally compliant.
