This SBIR Phase I project proposes to develop an easy to use, inexpensive, and portable bacterial concentrator to enable more sensitive cholera pathogen (Vibrio cholerae) detection. Cholera affects communities across 41 countries, including Mozambique in 2019 after Cyclone Idai and Yemen in 2017. Current methods used to detect the cholera pathogen in water involves a 3 to 5-day procedure due to th ...

Sterilization requirements in far-forward Roles 1 & 2 are challenging and not easily satisfied with currently available commercial devices. Steam-sterilant systems are hindered by excessive cube/weight, large power requirements, high water consumption and fragile unreliable designs. Non-steam options such as ozone and ethylene oxide have harmful residues, undesirable off-gassing, long cycle times, ...

Traditional manufacturing methods for producing warheads, propellants, and pyrotechnic systems are timely and costly. Additive manufacturing (AM) approaches offer one path of alternative manufacturing technologies. Among various technologies, powder bed fusion (PBF) is one promising approach. Hewlett Packards Multi-Jet Fusion printers utilize a unique PBF process that presents a desirable solution ...

The objective of this effort is to construct and test a 40 kW UPS with at least 100ms of holdup time, integrated into a standard 19 inch rack mount enclosure with 4U (7 inch) height, and designed to meet electrical and mechanical/shock specifications required for naval shipboard application. Traditional UPS applications are typically not optimized for weight and volume, and utilize bulky lead-acid ...

The objective of Phase I is to design, fabricate, characterize, and test ultrasonically absorptive aeroshell materials that successfully damp the second (Mack) mode instability to delay boundary layer transition (BLT) on hypersonic boost-glide weapons during the pull-up and glide phases. HySonic Technologies, LLC will experimentally and numerically assess the complex acoustic absorption coefficien ...

Modern and next generation military aircraft face increasing challenges as thermal demands grow while available heat sinks reduce. Legacy platforms upgraded with advanced electrical systems are also encountering similar thermal constraints. Modeling and simulation (M&S) tools provide a cost-effective solution to the design, analysis, and optimization of growing thermal management challenges, but t ...

To achieve the full potential of PMD/LAD technology for high performance space exploration missions mass reduction is essential. Screen channel acquisition devices are an interesting approach for future spacecraft using cryogenic propellants.  However, traditional manufacturing techniques (i.e. metal-based) are heavy and have reliability issues.  To achieve desired mass savings and scree ...

The nondestructivecharacterization of advanced composites, such ascarbon-fiber reinforced polymers (cfrp), by electromagnetic means iswell established [6]-[24].  What isneeded to advance the state of the art are sophisticated inversionalgorithms that allow layup and impact damage to be determined inlocalized regions, which means that the more traditional methods ofmodel-based inverse methods ...

According to the decadal report titled, Life and Physical Sciences Research for a New Era of Space Exploration, a Report, "...the AHB Panel would be remiss if it did not strongly recommend an animal centrifuge capable of accommodating rats/mice at variable gravity levels." Furthermore, the panel stated, “...research on animal models will be constrained without the ability to manipu ...

GTL proposes to further the development of its SNS technology towards adoption into aerospace structures. The SNS technology is an enabler technology for the expanded use of structural health monitoring systems. It allows the large data architectures needed for these types of systems to be implemented with minimal mass and impact to structural performance. GTL will accomplish this by automating th ...
