ACOUSTIC ANALYSIS OF FILAMENT-WOUND POLARIS CHAMBERS.
Abstract
An acoustical analysis was made of Polaris fila ment-wound chambers. The structural dynamic energy emanating from chambers during hydrostatic pressure tests was recorded by accelerometers and analyzed. Velocity-of-sound measurements were made to determine parameters affecting wave prop agation through composite structures. The anal ysis of recorded data has provided a method for establishing the structural integrity of a cham ber after it has been hydrostatically-tested to proof pressure. This verification may be made at lower proof pressures than those currently used. (Author)
