Environmental noise associated with turbulent boudary layer excitation

Objective

The ENABLE proposal will address the interior noise generated by the turbulent boundary layer around an aircraft which usually constitutes the most important source of cabin noise during cruise. The random character of the pressure distribution induced by the boundary layer has a major effect on the noise transmitted through the fuselage and its cross-spectral density plays a major role in determining the effective force causing motion to the structure. This project will provide the designer with predictive tools for the boundary layer induced noise The enable project will thus deliver enhanced models for the pressure fluctuations beneath a turbulent boundary layer (the effect of pressure gradients and skin surface roughness will be addressed), couple this models to structural transmission codes and validate the overall methodology against experiment undertaken during the project. Guidelines for the industrial use will be derived;
