The Aeroacoustics Specialists’ Committee (ASC) of the Council of European Aerospace Societies (CEAS) announces its 17th international workshop representing at the same time the 3nd workshop of the EU-Network “X-Noise EV”, to be held at the Escuela Técnica Superior de Ingenieros, located at the Sevilla university campus in Isla de la Cartuja .
Its subject is atmospheric and ground effects on aircraft noise. The objective is to bring together the aeroacoustics community with the technical and scientific disciplines classically involved in aircraft design. The workshop welcomes contributors from industry, research establishments and academia.
SCOPE OF THE WORKSHOP
The effects of the atmospheric conditions, ground characteristics and topography on the aircraft noise perceived on the ground is of great current interest in the aircraft noise research community. While the aeroacoustics of the main aircraft noise sources like the propulsion system and high lift devices have long been studied, in the end the sound generated by the aircraft propagates along distances ranging from hundreds of meters to kms, until reaching the receiver on the ground being specially perceived around airport locations. Therefore the knowledge about the aircraft noise propagation in the atmosphere is very important with a view to a proper evaluation of the noise impact around airports, and particularly to the computation of noise contours. This workshop represents one step to promote discussions on the important problems of atmospheric and ground effects on aircraft noise since they represent critical factors influencing the propagation of sound.
· State of the art of geometrical acoustic models capabilities to deal with the atmospheric, ground, and topography effects.
· Progress in the efficient application to the prediction of aircraft noise propagation, of computational tools to take into account those effects, based on the parabolic equation (PE) (e.g. Green’s Function PE-GFPE, Generalized Terrain PE-GTPE) or on fundamental approaches like the linearized Euler equations (e.g. Finite Differences Time Domain Models- FDTD) among others.
· Hybrid methodologies (e.g. PE-ray models, PE- FDTD) with consideration of micrometeorology codes if feasible.
· Experimental studies, including also field measurements of near surface meteorology to assess the effect of range dependent meteorological conditions on sound propagation.
· State of the art of the application of prediction methodologies for the effects on aircraft noise of atmosphere, topography and ground, to both the issues of noise impact around airports and long range propagation of noise from aircraft en-route.
