The U.S. Army has a future need for multiple secondary high explosive compositions that can also be used interchangeably as rocket propellants. In this proposal we will discuss a method of preparing such compositions via advanced spray drying technology and involving the use of a highly insensitive spray dried nitramine or CL-20 composition which have been plasticized with an energetic polymer t ...

Current production methods for tungsten fragmentation warheads are expensive and require significant labor to produce. Needed is a method that can maintain or improve upon the quality of the tungsten components while reducing the amount of time and labor to create the fragmentation warheads. Cold spray has the potential to answer both of these issues. Cold Spray Additive Manufacturing (CSAM) techn ...

Resodyn has developed the novel Resonant Acoustic Continuous Crystallizer (RACC) concept which is specifically configured for the recrystallization of energetic nitramines. This technology employs the Resonant Acoustic Mixing technology, which results in a uniform shear field throughout the mixing vessel. Radial mixing is accomplished to such a significant degree that true plug flow is achieved. C ...

Development of new lead-free replacements for lead styphnate and lead azide-based munition formulations made necessary to re-examine possible compatibility problems with current and future materials used for selecting adequate ammunition housings. Moreover, the compatibility/corrosion problems could be inherently associated with processing technology and therefore this aspect should be addressed b ...

Structural steels found in bridges and railways are damaged over time due to loading and the environmental conditions in which they operate. VRC Metal Systems, LLC in collaboration with research partners at Northeastern University propose to develop novel protective/repair coating materials that can be applied to bridges and railways by using the cold gas spray (CS) technology to improve the wear ...

The overall goal of this SBIR program is to develop waveguide-based, robust, high-rate, entangled photon pair sources suitable for use in space. These waveguides, fabricated at AdvR utilize periodic poling for efficient quasi-phase matched (QPM) spontaneous parametric downconversion (SPDC) of high energy pump photons into two lower energy signal and idler photons. AdvR’s approach is enabled by a ...

The US Army needs an effective method to augment and repair existing armor technologies. Nanoscale metal matrix composite (MMC) materials provide a promising combination of properties and could provide an ideal armor coating for increasing threat severity. Cold spray is a low temperature, solid state method of additive manufacturing that has shown promise for the deposition of hard, MMC materials ...

The U.S. Army requires additive manufacturing (AM) techniques that can repair and retrofit structures to improve ballistic survivability. Current AM processes have low deposition rates, are constrained by environmental chambers, and are not readily scalable for large-size production. The goal of this STTR topic is to develop a rapid-deposition ballistic-resistant-coating for metal panels. NanoCoat ...

Future U.S. Army vehicles will require engines with low heat rejection, high power density, lower-friction (15 % reduction), reduced fuel consumption (2-5% lower), and higher durability. Our team, NanoCoatings, Inc. (NCI) and Southwest Research Institute (SwRI), will down-select the most promising coating technologies and coating materials for both piston-rings and cylinder-liners. Our preliminary ...

The U.S. Army is interested in the development of innovative materials, films, coatings and technologies or manufacturing techniques which allow current U.S. Army airdrop related hardware and equipment to survive fresh and salt water operations with increased reliability and without damage and significant maintenance impact. Resodyn Corporation proposes for development a durable, moisture-impermea ...
