In this study, we investigate the noise produced by a propeller installed in a pusher configuration in close proximity to a wing. Experiments are conducted in a state-of-the-art anechoic wind tunnel to observe the impact of both static and in-flight conditions on overall noise generation. We found that as the separation distance increases, the interaction between the propeller and wing diminishes, causing the overall noise to approach levels similar to those of the rotor alone. A comprehensive comparison of predictions and measured results across various separation distances aids in understanding dominant noise mechanisms over a range of propeller and wing separations. At low separation distances, the potential field is the dominant mechanism of noise generation, while at higher separations, wake interaction is found to be the dominant source. This, in turn, facilitates understanding of noise generation from installed propellers and enables the design of low-noise configurations and the establishment of noise control strategies for installed propellers.
