Abstract

Multi-copters or drones are engaged in a wide range of industrial applications for flexibility, safety and low cost. The noise emission is becoming an issue with the expanding applications, among which the propellers that drive the drones are the major sources of noise. In this work, the noise characteristics of small-scale propellers are experimentally investigated using the advanced rotor aerodynamics and aeroacoustics test platform in an anechoic chamber at the Hong Kong University of Science and Technology (HKUST). The study will focus on several small propellers, including the off-the-shelf ones. The rotor noise will be measured by a linear array with 18 microphones, and the aerodynamic forces will be acquired by using the high-accuracy load cells. The dependence of both the tonal and broadband noise radiation with the thrust and rotation speed at various conditions will be tested. The study will enhance our understanding of the noise features of the multi-rotor powered drones and provide us with a better understanding of the status of the drone noise impact on the environment.
