Abstract

The objective of this proposal is to develop highly reliable technologies for a fast and slow cook-off mitigation sensor activated by thermal energy. Systima proposes to integrate an auto initiator, MIL-STD-1901A safe and arm mechanisms, and novel techniques into a sensor that will initiate a venting system. Systima s approach provides a method to safely and reliably initiate rocket motor case venting systems to prevent fire induced catastrophic munition or rocket motor failure without the need for standard batteries, special thermal sensors, wires, etc. Typically an externally powered mil-standard squib or NASA Standard Initiator (NSI) activates these venting systems. One of Systima s approaches simplifies the system by combining both the squib and power source into a single sensor/activation unit. Systima s other approach combines existing technologies in new and novel ways to power the mil-standard squib. The auto initiator in Systima s mitigation sensor will make the venting system, both a passive and active system, looking for and activating at the appropriate temperature. When the sensor detects the appropriate conditions (i.e., fire or explosion) it will self activate and then initiate the highly responsive venting system, such as Linear Shape Charge (LSC).
