UAV noise remains a major concern for the widespread implementation of these aircraft in a wide array of potential applications, especially in the urban environment. Moreover, not only overall noise levels must be considered when analyzing the impact of UAV noise; noise quality based on the spectral content of the acoustic signal must be considered due to the psychoacoustic impact on the listeners. Also, as UAVs become widespread, the ability to perform field replacement of propellers using additive manufacturing (AM) is of increased interest to many operators. However, as different AM techniques become popular, their impact on performance and noise must be assessed. In this investigation, we experimentally test the same propeller geometry manufactured using the most popular AM techniques, evaluating how different characteristics such as surface roughness, anisotropy, and flexibility affect the propeller. Finally, we performed a numerical campaign to isolate these effects and better understand their effect on propeller noise and performance.
