von Karman Institute Lecture Series and Events

Accurate and Efficient Aeroacoustic Prediction Approaches for Airframe Noise

March 25-28, 2013

Rhode-St-Genèse, Belgium

Aircraft noise remains a key societal and economical concern, and ambitious targets for noise reduction have to be achieved to ensure a sustainable air transport. Meeting those ambitious objectives requires unprecedented joint efforts for the modelling, prediction, and eventually mitigation of aircraft noise. The latest developments thereto will be exposed during this Lecture Series, by top-rank international experts in the field. In particular, advanced scale-resolved and stochastic approaches will be described and applied to generic but representative configurations relevant to flap, slat and landing gear noise issues. Based on validations with extensive experimental databases collected in the framework of the EC FP7 VALIANT project, the limitations and perspectives for the further evolution of state-of-the-art simulation methods will be discussed.
