In the proposed program, Systima Technologies Inc. will develop a tunable ETIVS thermal trigger system for integration into Navy weapon system platforms. The ETIVS trigger technology leverages Systimas existing thermal sensing technology and expertise in design of devices for IM mitigation of solid rocket motors. Benefits of Systimas ETIVS device include passive operation (no power required) until detection of SCO or FCO environment, a demonstrated MIL-STD-1901A/MIL-STD-1316 compliant in-line initiation system, consistent performance at various heating rates, and lightweight and compact design that is well suited for motors having D=5. In the Phase I program, Systima developed an ETIVS system concept design, established functional and performance requirements, created and developed an electrical processor design that functions at high temperature, and identified candidate system components. The Phase I effort also included breadboard fabrication and proof-of-concept testing of the processor assembly and acceleration lock-out feature. The Phase II program will optimize the system design, mature the processor design to ensure compliance with the relevant safety standards, and include functional tests and environmental testing with prototype ETIVS trigger systems to demonstrate performance and reliability. Full-scale SCO/FCO tests will be conducted per MIL-STD-2105D with TIVS energetic materials (LSC) to bring the ETIVS sensor technology to TRL=5-6.
