Ignition of rocket motors can be performed using low-volt firing components, but MIL-STD-1901A requires mechanical isolation for safety. While traditional safe & arm devices are available, they are relatively large and heavy. Recent progress in MEMS has developed miniature safe & arm devices for low-cost munitions such as 40MM grenade and airburst munitions. The Black Hills Nanosystems team has ...

ABSTRACT:The need for a natural language query capability for DoD regulations is identified. A technical solution based on artificial intelligence, cognitive computing, and natural language query technology is presented. In Phase I, various techniques will be investigated, and one or more solutions will be developed and tested. In Phase II, the down-selected technologies will be refined and built- ...

The overall objective of this Phase I effort is to determine the feasibility of defeating CBW production facilities via an X-ray source that would fit within the volume constraints of a munition platform. First, Battelle will conduct a system trade study focused on determining the key performance requirements of an X-ray source suitable for use against CBW and C4 complexes, identify the input requ ...

At the completion of the research and development effort a Li foil multi-wire proportional counter (MWPC) neutron detector with more than 625 cm^2 of active area will be included in a portable radiation detection system. The system is expected to have an intrinsic thermal neutron detection efficiency of 55% or greater and gamma-ray rejection ratio (GRR) of 1.0x10^-8 or better. A gamma-ray spectrom ...

ABSTRACT:Specialty elastomers, such as hydrogenated acrylonitrile-butadiene rubber (HNBR) and fluoroelastomer (FKM), are widely utilized as high performance seals in numerous aerospace vehicles and components. The elastomer sealing industry and its products are primarily based on a limited pool of feedstocks that were last advanced in the 1970's. Using current technology, elastomeric seals must b ...

"The overall objective of the proposal is to improve performance of polymer matrix composite materials for cryogenic tank applications. The specific objectives of the program are:1. Determine the effect of cryogenic exposure on PMCs, particularly on the interphase region.2. Examine failed composite cryogenic tanks at the nanometer-level and higher to understand failure mechanisms.3. Develop ...

"The objective of this Phase II proposal is to develop a hand-portable waterless decontamination system based on Reactive Nanoparticle Technology to address chemical and biological threats. Currently fielded chemical warfare decontamination technologieseither rely on harsh oxidants (such as bleach) or logistically complicated bulky, equipment (such as high temperature pressure washers). An ideal ...
