Non-Explosive Broadband Acoustic Source Using Metallic Based SHS-Water Reactions

"Metallic based self-propagating high temperature systhesis (SHS)reactions provide the opportunity to develop safe handlingexplosve sources that can only be activated underwater. The Navyis currently seeking a non-explosive, command activated,broadband acoustic source for multi-static anti-submarinewarfare. Key attributes for attaining the stoichiometric yield ofmetallic based SHS-water detonations depend on the oxidationproperties of the materials at high temperatures and thedispersion characteristics in seawater. The object of the PhaseII research is to demonstrate the explosive yield of the metallicbase SHS-water reactions and to characterize the acousticparameters in a ocean test bed. In the Phase II Option, thedetail design of housings, deployment mechanisms, the ignitionand control systems necessary to deploy and direct a broadbandacoustic pulse using the metallic based SHS-water reactions willbe investigated.BENEFITS: Development of a high-energy underwater acoustic source has excellent dual use applications. Military acquisition of metallic based SHS materials includes underwater acoustic sources, miniature interceptor components,inititators, rocket igniters, IR decoys, time delay elements, incendiary ammunition, and destruct systems. Commercial applications in the oil exploration industry include the use of metallic based SHS-water activated explosives for seismic analysis,borehole core sampling, casing perforations and
