Abstract: |
Thermally Initiated Venting Systems (TIVS) are a safety prerequisite for meeting DOD IM requirements. Tanner Research will leverage existing TRL-7 electronic Safe and Arm and Arm/Fire device (ESAD/EAFD) hardware in combination with COTS energy harvesting to develop and demonstrate in Phase I a proof of concept in-line electronic TIVS. To preclude Fast- and Slow Cook-Off (FCO/SCO) incidents and catastrophic losses will require multiple sensor integration and embedded electronic architecture. That is, `smart-munitions-related' sensor-fuzed architectures which are compact, require, almost no stored energy, and also are able to be customized for a variety of environments. . Tanner Research proposes to implement such an electronic TIVS meeting MIL-STD-2105 criteria for venting utilizing IM-compliant ESAD/EAFD and shaped-charge EFI detonator(s) or linear arrays that are powered and controlled by energy scavenging. Operating principles include: event detection, weakening of motor casing with focused blast-energy, or use one or more linear cutting charges in the event of slow temperature rise meeting SCO criteria, or rapid, widespread FCO conditions (e.g., fire). |
Benefits: |
This Phase I/II will result in an ETIVS system that meets and exceeds the current goals of the solicitation. A prototype TIVS will be demonstrated that will scavenge energy from the FCO event and be able to safely control solid propellant burn to a Type V reaction. Due to the miniaturization of the electronics and associated hardware, our TIVS will be not only applicable for small 5-inch missiles, but MDA BMDS and traditional space launch markets as well. |
