Tanner Research, Inc. — Department of Defense SBIR Phase I: Thermally Initiated Venting Systems (TIVS) are a safety prerequisite for meeting DOD IM re

Description

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).
