Reduction of noise

Most of the articles of this issue address numerical simulations and the thorough understanding of noise generation, topics which are directly linked to" the reduction of noise at the source", probably the most conventional axis for noise reduction among those promoted by the International Civil Aviation Organization (ICAO) "balanced approach"
Great progress has been achieved in noise reduction of the engines over the past decades, so the aerodynamic noise is not negligible anymore, particularly in landing configuration. copyright © ONERA 1996 2006 -All rights reserved
