The unsteady wall pressure generated by a ducted propeller is measured using the remote microphone method. The variations in inner-wall pressure fluctuations with duct length and propeller axial position are characterized, and the results are compared with predictions from an analytical model and with far-field noise measurements to provide further insight into the underlying physical mechanisms.
