To further simplify the sensor array set-ups and improve the mode detection capability for the aeroengine fan noise test, a new compressive sensing based methodology has been proposed. This paper reports the details of the validated aeroengine fan noise test method and the wind tunnel test results for the validation. The experimental set-up consists of a transition duct to the open jet, a mode synthesizer to generate different modes of characteristic fan noise, and a sensor array to conduct mode detection in the presence of background flow speeds and background noise interference. The main attention is primarily focused on the examination of the associated reconstruction accuracy and probability of success for spinning mode detection. The testing results clearly show the potential capability of the proposed new testing method for aeroengine tests in a practical testing facility.
