Abstract

The aim of this research is to attenuate the acoustic noise transmitted into a rocket faring by using a piezoelectric network. The paper makes two assumptions that faring structures can be deformed by actuation forces, or, not be deformed by them (i.e., easy-to-deform or hard-to-deform cases). We characterize both of these and develop acoustic controls for each. Experiments and numerical simulations demonstrated that our methods attenuated the acoustic level generated not only by simple monochromatic noise, but also broadband noise. Unique Issues concerning the acoustic problem were identified that have not been clearly recognized in the vibration suppression problem. Our attenuation method based on an energy-harvesting technique was shown to be effective for the acoustic problem in realistic hard-to-deform faring structures.
