This study aims to enhance UAV propeller performance by addressing aerodynamic inefficiencies caused by shock waves at high rotational speeds, which are also known as vortex formation. These shock waves, occurring at the propeller tips, increase drag, vibration, noise, and potentially can reduce flight time. The research focuses on optimising propeller design to minimise these effects and improve overall efficiency. The methodology involved a comprehensive review of existing propeller designs and the application of aerodynamic principles to develop a propeller approximately 9 inches in length. The background study also focuses on the application of biomimicry in the design of propellers. Simulation tests were conducted to evaluate its performance, with measurements taken at various rotational speeds, including a maximum rotational speed of 6000 rpm. The results demonstrated that the newly designed propeller achieved better efficiency compared to existing models, producing a thrust of 0.0016 N at maximum speed. The design also exhibited reduced noise and vibration, contributing to a more stable and efficient flight performance. The findings underscore the potential for improved UAV propeller designs to increase the efficiency of performance and enhance operational capabilities, particularly in applications like agriculture, inspection, and surveillance. Future research may explore additional modifications to further optimise aerodynamic performance and noise reduction.
