Drones, also referred to as unmanned aerial vehicles (UAVs), have become increasingly popular for a variety of uses, from industrial and military to recreational. One ongoing issue with drone technology is the noise produced by the propellers while in use. This study explores a novel approach to mitigate drone propeller noise by the adoption of serrated propeller designs. The main goal of this research is to examine the effectiveness of serrated propellers in reducing the acoustic footprint of drone operations without compromising performance. The propeller is fabricated using 3D advanced manufacturing techniques. The aerodynamic and acoustic characteristics of conventional and serrated propellers is analyzed using computational fluid dynamics simulations. The Ansys Fluent with RNG k-ϵ turbulence model is used to solve the mathematical equation. Experimental validation has been conducted through controlled flight tests, where drones test benches equipped with both conventional and serrated propellers. The acoustic measurements are collected to assess the impact of serrated propellers on noise levels. The different motor powers of 25, 50, and 90% were used for the simulation and experiment to analyze the characteristics of noise emission from the propeller. According to the result obtained, it shows that the noise reduction is only effective up to 50% of motor power and approximately a 5.7% decrease compared with conventional propeller.
