AbstractThe development of a high-shock data recorder for use in projectile penetration and pyrotechnic environments is critical to understanding the loads that warhead systems are exposed to in tactical applications. Data from recorders mounted inside warheads can be used by researchers to measure loads on the warhead, fuze, and explosive fill components as well as validate analytic and computational models of a weapon system. The objective of this research program is to continue the development and testing of a high-rate, high-shock, miniature data recorder. The completed DSR data record will include 4 internal analog channels for measuring acceleration, weapon-case strain, or pressure and 8 external input digital channels for other user defined measurements. High-sampling rates will allow for high- frequency content measurements (common in pyro-events) and novel shock isolation techniques to be employed to protect the data recorder from shock induced failures. We propose to manufacture and support testing to validate, in realistic high-velocity penetration and pyro-shock environments, the capabilities of the DSR data recorder. Residual units will be provided to the DoD at the end of the Phase II effort along with a plan for commercialization of the developed system.
