A system noise assessment of the NASA single-aisle over-wing nacelle configuration, the OWN160, is carried out to estimate the performance of the configuration relative to NASA noise goals. The vehicle was first designed during the Environmentally Responsible Aviation(ERA)project, and last analyzed in 2016.Renewed interest in the concept necessitates an updated acoustic prediction. A model for jet-trailing edge interaction noise is developed from experimental data and included in the system noise assessment and analysis. Total system noise is predicted using NASA’s research-level Aircraft Noise Prediction Program (ANOPP-Research). Results are evaluated with and without the jet-trailing edge effect and compared to prior analysis and an equivalent conventional aircraft configuration, the TW160. The jet-trailing edge interaction affects the noise source ranking and increases the total noise of the OWN160, but the concept retains an advantage for noise reduction when compared to the conventional configuration with a cumulative reduction of 7.7 EPNdB (ERA results showed a 9.7 EPNdB reduction).
