Study of bridgewire size and pyrotechnic density relationships on all-fire levels

Conference ·
OSTI ID:6632781
The effects of bridgewire size and pyrotechnic density on the characteristics of a hot wire test device were evaluated. These characteristics were examined before and during initiation. Five bridgewire diameters and two loading densities were examined. Groups of hot wire devices of each bridgewire and density combination were fabricated. After final assembly, electrothermal response data were obtained on each test device, and a normalizing technique was introduced so that all groups of test devices could be compared. Then, each group of devices was subjected to a Langlie all-fire test to determine the threshold initiation current for each configuration. The results obtained reveal important boundary conditions and limiting factors related to the functioning characteristics of hot-wire devices. This information may be used to develop improved techniques of hot-wire device design such as computer modeling. Further study in this area would be valuable and is warranted.
