Development of Fast and Slow Cook-off Mitigation Sensor

A self-powered cook-off sensor is a critical path item for meeting federally mandated insensitive mention (IM) requirements. The sensor must reliably help the venting system mitigate fast and slow cook off when temperatures hit the range of 275°F to 350°F. The output from the sensor must appropriately and consistently power the SRM venting system. MSI’s proposed solution is to use modules that convert thermal energy from applicable cook off environments to electrical energy. Based on pre-proposal testing of candidate modules, MSI is confident that the proposed approach can meet the power, timing, volume, weight, and ruggedization requirements for this critical application. During Phase I, MSI will specify, evaluate, analyze and bench-top test the most appropriate system components, and create a preliminary sensor design including the circuitry and component arrangement. Additional testing will be performed to demonstrate performance. Structural analysis will be used to confirm weight, volume, and operating life goals are feasible. Measured performance coupled with packaging design and evaluations will be used to prove that MDA goals can be achieved if the Phase I project continues into Phase II. The Phase II effort will focus on providing MDA with a viable prototype self-powered sensor that meets MDA needs.
