Fast prediction method of aircraft noise with distributed propulsion in the far field

Abstract

Abstract Based on the known methods for calculating the propeller noise, a fast prediction method of the distributed propulsion noise is proposed. The method takes into account only the component of tonal noise from the load. To test the adequacy of the model, the GL-10 model was used, a concept of an aircraft developed by National Aeronautics and Space Administration to test distributed propulsion as well as vertical take-off and landing maneuvers. The comparison showed a good agreement between the results obtained and the data for the GL-10 model.
