Abstract
During flight mission, the high-intensity level acoustic load generated by large launch vehicle lift-off propulsion is of major concern for the integrity of the launch complex and the vehicle payloads. Acoustic loads are principal source of structural vibration and internal noise during launch. The prediction of the acoustic loading at the surface of rocket fairings is challenging because of the complexity of the fairing geometry. The proposed approach is to minimize the weight and the surface of the Small launch vehicle faring (SLVF) towards minimizing the effect of the interferences for height frequency of the external acoustic waves using a genetic algorithm.
