A third-generation of in-line, liner-style hydraulic suppressors was developed that takes advantage of advancements of syntactic foam technology. The chemistry of the developed liner was varied so that the acoustic properties of the foam could be retained when repetitively exposed to the extremes of the hydraulic environment. The developed liner uses microspheres that can be charged to an elevated initial microsphere pressurization which results in an increased acoustic performance at elevated system pressures. The developed liner also addresses the limitations of the first and second-generation liner-style suppressors in terms of initial volume fraction of microspheres, allowing for enhanced acoustic performance over broad pressure ranges.
