Fine powder thermal battery cathode materials can exhibit challenging flow properties which makes processing with automated presses difficult.Granulating these powders can substantially improve flow properties and reduce the tendency for powder segregation during handling and pressing operations.Additionally, the properties of MgO that lead to good performance in thermal battery separators are not ...

VASST seeks to secure large systems, overcoming challenges arising from size and scale, vulnerability analysis, and cyber and physical integration. It defines vulnerabilities at the component level and translates their effects up to the system level. It does this in a two stage process, with the first stage seeing the evaluation of cyber vulnerabilities to produce model effects which are in turn e ...

Under Phase-I of MDA SBIR 16.3-021, i3 demonstrated a new time-efficient technique, the i3 Transient Decomposition Method (TDM), for generating statistically-based material response models that predict the decomposition process that thermal protection system materials undergo when exposed to severe aerothermal heating environments. The i3 TDM is an enabling technology for MDA and other agencies th ...

The objective of this Phase II project is to complete the research required to deliver to the THAAD program for military qualification testing a low cost, easy to use, passive, nonreversible, MEMs based, chemiresistor sensor for the detection of hydrazine in missile canisters. The Air Force has set the maximum exposure limit to hydrazine at 10 ppb for an 8-hour period. A hydrazine sensor is need ...

Low cost, boost phase nozzles are needed for missile defense systems. Boost phase intercept missiles require high thrust motors that operate at very high pressures and temperatures. The nozzles must survive high thermal strains with minimal erosion to maintain performance. Current R&D focuses on non-eroding and DACS materials. However, low cost fabrication technologies and innovative nozzle design ...

The Phased Derived Range (PDR) method generates higher resolution object features than current radar processing methods, making available more physics based features for discrimination. These new physics based PDR features must be combined with currently existing features to determine if new information is being brought to the table. This determination is performed with adaptive feature selection ...

The threat of cyber-attack comes from many sources. Sophisticated attack software, novice hackers, and foreign operatives recruiting dissatisfied individuals within an organization to compromise system operations. Because inside attackers have legitimate access to privileged system resources, their activities can be particularly malicious, going beyond intrusion, theft, or destruction of data. ...

Current production of thermal batteries relies heavily on touch labor practices. The assembly of the battery stack relies exclusively on touch labor, which has been shown to be the major insertion point for battery defects that are discovered during post-production evaluations of batteries. In Phase I, Creare successfully demonstrated the critical subsystems of an innovative approach to battery ...

Reliable and accurate thermal battery nondestructive evaluation during production and as part of pre-acceptance qualification procedures is central to ensuring that the quality of thermal batteries remains high. Current production inspection practices are inadequate because not only batteries with defects continue to enter the stockpile, but also productivity is adversely impacted. In Phase I, w ...

Sentar's Work-Centered Interface (WCI) for Computer Network Defense (CND) provides decision support for computer security by combining a multi-agent architecture with work centered design concepts. Based on Sentar's KnoWebr architecture, the WCI integrates distributed information resources to provide situational awareness, rapid assimilation, and effective response in a variety of application dom ...
