Noise from unmanned aerial vehicle propellers Seminar

This presentation will discuss work done by myself and my PhD students investigating the noise generated by the small propellers typically used on commercially available quadcopter unmanned aerial vehicles (UAVs). Recent work we have undertaken suggests that when these propellers operate in standard atmospheric conditions at a condition representative of hover, the turbulent inflow into the propeller will generate significant levels of noise. Part of this talk will describe a theoretical model which we have developed to predict this noise source and the validation of this model against experimental data. The method has been recently extended to include the aerodynamic and acoustic scattering effect of a shroud around the propeller and those extensions will also be described. The talk will also cover related work including: the noise generated by a strut mounted adjacent to the propeller; the noise generated by contra-rotating propellers; and some interesting methods for measuring the pressure field radiated from a propeller.

Dr Michael Joseph Kingan, University of Auckland

"I obtained my engineering degree and PhD from the University of Canterbury in Christchurch, New Zealand. Following that I worked as a postdoctoral fellow and then as lecturer at the Institute of Sound and Vibration Research at the University of Southampton from 2007 till 2014. During my time in Southampton I primarily worked on developing methods for predicting and analysing the noise from contra-rotating advanced open rotors. I returned to New Zealand in 2015 to take up a position at the University of Auckland. Here I have broadened my research interests to include topics in the general field of acoustics and particularly the aeroacoustics of small propellers."
