The shift towards sustainable and eco-friendly future of aviation is further catalysed by the aggressive targets set by administrative and industrial stakeholders. It has emerged as one of the solutions with the potential to increase overall efficiency and improve noise emissions. This paper characterises the flow and acoustic field associated with a DEP propeller. A hybrid methodology using scale-resolving turbulence formulation and an acoustic analogy is used to predict aerodynamic noise generation and acoustic wave propagation to the far-field for an isolated DEP propeller. The numerical predictions are observed to be in reasonable agreement with the measured values for both aerodynamic and aero-acoustic attributes. The sensitivity of far-field acoustic spectra to the integration surface is also presented. The results are further analysed to identify dominant noise sources in the system including propeller and wake flows.
