Abstract: In order to characterize Ariane 5 fairing acoustic loads at lift-off, tests were carried out on a motorized scale model of the launcher on its pad. The objective was to find a simple source description of the incident field on the fairing, which is intended to limit the input parameters required for the structural response computations, to reduce the inherently very long computation times. For that purpose, we developed two simple source models which both used a small number of uncorrelated plane waves. One i…
