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 ...

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 ...

This proposal seeks to address the need for improved performance in infrared imaging systems by developing an unconventional infrared detector technology. We seek to demonstrate performance improvements based on an emerging class of novel materials, namely bismuth chalcogenides, and a detector architecture employing graphene / bismuth chalcogenide heterointerfaces to facilitate efficient charge tr ...

Linear mode avalanche photodiodes (APDs) will be developed in III-V materials epitaxially grown on commercially available GaSb substrates. The detectors will have bias-controllable internal current gain greater than 10, limited excess noise, and response times shorter than 0.5 nanosecond. In Phase I, initial APDs will use InAsSb absorbers, producing response out to 4.2 micron wavelengths. Next, AP ...

Advanced numerical simulations of fluid flow and solid/structural mechanics are often used to assess the vehicle or engine performance, to identify the mechanical factors that contribute to the shortening of their life span, and to suggest design modifications that improve efficiency and durability. The latter often results in significant cost savings to the DoD. As the vehicle and engine designs ...

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 ...

Modern deep learning-based face recognition systems perform at or above human levels on high quality frontal imagery, but their performance suffers significantly on more operationally relevant imagery with confounding factors such as extreme pose.  This performance degradation is based on two primary shortcomings: poor match between training and test-time image data, and failure to model inherent ...
