Noise prediction toolbox used by the DLR aircraft noise working group

Abstract

Focus of the activities of the aircraft noise working group of the German Aerospace Center (DLR) is the development and application of aircraft noise calculation models. The different tools currently in use are covering the range from best practice models like FAA´s INM or the German AzB up to the sophisticated partial-sound-source models SIMUL and PANAM, which were developed at DLR during the last years. Consequently, the field of application is very large – reaching from the classical aircraft noise prediction tasks for land-use planning up to a noise optimization already during conceptual vehicle design. This paper gives an overview on these tools, typical applications as well as their advantages and limitations. Special attention will be paid on the SIMUL and PANAM models, which are currently used mainly for scientific applications.
