During the proposed Navy STTR program, NanoSonic and Virginia Tech will design and synthesize innovative, high strength ceramic nanocomposite microcapsules filled with > 80 volume percent water that are empirically optimized to function as readily dispersed powdered additives with long-term water retention, durability during air craft bladder production, and rupture during ballistic shock. NanoSon ...

The Navy is actively developing a self-sealing, water-activated fuel bladder to mitigate fuel leaks upon mechanical shock (e.g. penetration by a .50 caliber bullet). To circumvent the requirement of an external water source to activate the self-sealing, this system will require water-filled microcapsules that can be incorporated directly into the polymeric matrix of the fuel bladder. Upon mechanic ...

Data generated by training exercises needs to be consolidated and processed to derive more efficient, effective and adaptive training scenarios through training objective and measures of performance analysis. The main technical challenges addressed by this solution are: data from diverse sources must be pre-processed (i.e., validated, cleaned, synchronized) and loaded into a data warehouse; the ce ...

Compared to current practices of todays processing, exploitation, and dissemination (PED) cycles for fusing the outputs of single-sensor-processing chains during the feature- or decision-level fusion tasks, combining modalities at the data level to learn the target-signatures offers an opportunity to utilize the mutual information among the raw signals generated by the same target. Hence, the auto ...

Portable Advanced Battlefield and Ground surveillance radar can now provide effective detection of small targets, posing challenges for troop movement and stealth missions. Radar absorbent strategies have been achieved in composites and larger textile objects, but effective light-weight solutions for current operational clothing and individual equipment systems such as uniforms, knapsacks and body ...

The Air Force has a requirement for a real-time system to monitor High Energy Laser (HEL) damage effectiveness and provide laser hazard assessment.Due to target reflective properties and environmental conditions, HEL effectiveness may be compromised, so operators require real-time assessment to determine if lasing should continue or if other methods should be employed.To keep operators safe, laser ...

There are numerous ongoing research and development efforts on SansEC technology for applications to enhance warfighter and commercial technologies. Two major SansEC applications of interest are (1) the detection of damage on composite airframes, (2) the measuring of the shape of morphing airframes actively in-flight, and subsequently feeding this information back to a flight control system in rea ...

The focus of this proposal is FA-002 - artificial intelligence (AI), which will be used for the hardware cyber security. AI will link the THz and sub-THz responses at the pins to the defects and deviations from design of the integrated circuits under test. An increasing complexity of digital and mixed-signal systems makes establishing the authenticity of a chip to be a key problem. New rapid, inex ...

There are two main objectives that this proposal addresses. The first is to develop an oil additive that reduces friction and is thermally conductive and designed to increase engine efficiency and equipment lifecycles.This will be obtained through further material production and testing.Once the desired thermal conductivity and friction coefficient is achieved, the oil additive will be tested at S ...

Free Space Optical (FSO) communication systems offer extremely high throughput links over long distances, with impressive LPI/LPD characteristics. However, they are often susceptible to deep fades due to atmospheric effects or terrain blockage, as well as scattering due to scintillation. High-rate radio frequency (RF) communications systems currently offer data rates approximately an order of magn ...
