Investigation of Acoustic Fill Effect of a Launch Vehicle Payload Fairing

<div class="section abstract"><div class="htmlview paragraph">The payload fairing of a launch vehicle is subjected to extremely high acoustic loads, with peak levels occurring during lift-off and transonic aerodynamic regimes. The external acoustic field penetrates the fairing, producing intense internal sound pressure levels that can challenge the integrity of spacecraft components. Accurate characterization of the vibroacoustic behavior of the payload fairing and its enclosed cavit
