Multi-Shock Survivable In-Line Electronic S&A Device (ESAD) with Built-in Test (BiT) Navy SBIR FY2016.1 Sol No.: Navy SBIR FY2016.1 Topic No.: N161-019 Topic Title: Multi-Shock Survivable In-Line Electronic S&A Device (ESAD) with Built-in Test (BiT) Proposal No.: N161-019-0359 Firm: Tanner Research, Inc. 825 S. Myrtle Ave. Monrovia, California 91016 Contact: Nate Selden Phone: (626) 471-9724 Web Site: http://www.tanner.com Abstract: In 2002 Tanner Research developed and demonstrated an in-line high voltage Initiation Safety Device (ISD) using exploding foil initiator (EFI) detonator. By 2015 a micro-scale implementation of the 6th Gen. ISD has embedded built-in test (BiT) capability (electronics and energetics) for ongoing use in MIL-STD 1901 applications as rocket motor ignition system, and in similar MIL-STD-1316 warhead initiation system applications. Tanner proposes to G-harden our baseline electronic S&A device (ESAD) for pyrotechnic shock. As such shock induces high amplitude and high frequency displacements, Tanner is proposing to mechanically attenuate a baseline 6th Gen. ESAD by decoupling the electronics from the external package. As the existing design is firmly encapsulated within a rigid, 1-inch diameter metallic through-bulkhead initiator (TBI) structure, there is significant room for additional damping and attenuation components to be judiciously added. We expect to test, evaluate, and assess this architecture empirically to determine survivability using the existing BiT for analysis. Benefits: Tanner Research, Inc. has TRL-7 ISD hardware in micro-scale with 100-nanosecond response time to facilitate demonstrating warhead fuzing and survivability following pyroshock testing. This proposed solution leverages available fireset technology and ISDs in a unique design suitable for evaluating mechanical isolation techniques to meet the specified survival criteria, in addition to providing a clear path toward future applications in multiple naval munitions.
