Abstract

Applied Physical Sciences (APS) and the Pennsylvania State University Applied Research Laboratory (ARL/PSU) will collaborate in the development of a novel sensor system to measure the low frequency acoustic pressures within a fluid-filled pipe. The proposed concept improves upon the Navy s current Array Based Acoustic Measurement (ABAM) system for laboratory characterization of full-scale piping components. The initial trade study will consider a range of sensing options including discrete sensor arrays and conformal sensors consisting of film and fiber wraps. The trades will balance sensitivity to the acoustic pressures against rejection of non-acoustically driven response, structural response, weight, cost, and ease of application in a shipboard environment. The design effort will leverage the team s significant experience with measurements and modeling of pipe structural-acoustic response, as well as experience developing sensors for many of the Navy s most challenging applications.
