Abstract

A significant part of cabin noise in airplanes originates from the engines. Before the engine’s sound pressure field is impacting the fuselage surface to subsequentially excite cabin noise, it undergoes changes due to the fuselage’s boundary layer. In a joint project between Airbus and DLR, the influence of the mean boundary layer flow as well as of the unsteady turbulent fluctuations on the sound field has been studied for cruise conditions (M=0.8).
