Prediction noise of propeller on wing for distributed electric propulsion configuration

Abstract

This paper presents a fast way to predict the noise level of installed propeller on wing. Installing the propeller on wing has not only increased wing lift coefficient, but also greatly changed the noise direction. However, the precise prediction of noise level is a difficult and cumbersome, since the aerodynamic interaction effects are so complicated. But with a series of simplicity, here still can get a concise formulation, which is sufficient to evaluate the noise level of early design of propeller-driven aircraft.
