Abstract: This study presents the design, aerodynamic analysis, structural evaluation, and experimental validation of a UAV propeller optimized tor efficient thrust generation under low-speed operating conditions. The propeller was developed using the NACA 6409 aerofoil, chosen for its superior lift-to-drag characteristics and suitability in low Reynolds number regimes typically encountered in small unmanned aerial vehicles. The aerofoil selection plays a critical role in enhancing propeller efficiency and ensuring stable aerodynamic performance. A detailed three-dimensional model of the propeller was created using design software. Key geometric parameters, including blade pitch, chord length, and twist distribution, were carefully defined to achieve optimal performance. The 3D modelling process enabled accurate representation of the propeller geometry, which is essential for both aerodynamic and structural analysis. Aerodynamic performance was evaluated using computational fluid dynamics (CFD) simulations in ANSYS. These simulations provided insights into thrust generation, pressure distribution, and airflow characteristics around the propeller blades. The results were used to assess performance efficiency and identify potential improvements in the design. Structural analyses were also carried out in ANSYS to ensure the propeller's strength and reliability under operating conditions. Tensile, compression, and fatigue tests were performed to evaluate the material's ability to withstand mechanical loads and repeated stress cycles. These analyses ensured that the propeller meets safety and durability requirements.
