Abstract

Problems of a decrease in acoustic loads on complex-shaped objects within a cylindrical shell are encountered frequently in practice. A good example is adjustment of a space vehicle to an assembly protection unit of a carrier rocket. This study presents a mathematical model for determining acoustic loads acting on an object and depending on the factor of acoustic energy absorption by surfaces. As a result, the spectra of the root-mean-square levels of the acoustic pressure have been obtained as functions of the area of a shell surface coated with a sound-absorbing material, as well as the area of an object beneath it.
