Parametric Study of Sawtooth Serration Geometry for Noise Reduction in HTOL Propellers

Recently, the development of UAVs, or drones, has intensified, but one major challenge that surfaces is the noise generated by their propellers. To overcome this issue, it is essential to explore the concept of low-noise propellers constructed with sawtooth serration on their trailing edges as a promising solution. This paper investigates the effects of sawtooth serration on UAV propellers, specifically in the context of horizontal take-off and landing configurations. Using ANSYS Fluent, extensive testing will be conducted to determine the most effective serration geometry for the propeller. The outcome of this research aims to contribute to the development of quieter and more efficient UAVs, addressing the noise reduction challenge and fostering innovations in UAV technology. From the simulation result, the highest noise intensity reduction is approximately 3.101% lower than the non-serration propeller.
