An important issue for the aeronautical industry is the reduction of aircraft noise. The rotor–stator interaction is a predominant part of the noise emission. Presented are an introduction to these interaction theories, whose applications are numerous. For example, the conception of air-conditioning ventilators requires a … See more As the source levels can't be easily modified, it is necessary to focus on the interaction between those levels and the noise levels . The transfer function Where M is the See more • Sijtsma, P.; Schulten, J.B.H.M. (2003). "Wake modelling accuracy requirements for prediction of rotor wake-stator interaction noise (NLR-TP-2003-124; AIAA Paper 2003-3138)" See more The minimization of the transfer function $${\displaystyle {{F_{m}} \over {P_{m}}}}$$ is a great step in the process of reducing the noise emission. … See more All this study was made for a privileged direction : the axis of the rotor–stator.
