The objective of this proposed Small Business Technology Transfer (STTR) effort is to develop an experimentally-validated, highly detailed chemical kinetic reference model of surface chemistry for C-SiC-SiO2 rubber composite materials exposed to high temperature, high pressure, oxidizing environments. This reference model will then be reduced into simplified reduced-order models that could be easi ...

Vertical short takeoff and landing (VSTOL) operators face numerous challenges, particularly during takeoff, hover, and landing operations. Threats take the form of power lines, structures, and—in the case of combat—enemy fire. Often, these threats are obscured when visibility is compromised by dust, sand, or snow. Maintaining awareness of the surrounding environment becomes almost impossible. ...

APS has assembled a world class team to address problems associated with rail gun launcher operation. APS has combined its unique processing experience with IAT's railgun design, testing and characterization experience to develop materials to improve rail gun performance. Phase I will be devoted to fabrication and testing of various samples in rail gun conditions. Phase II will focus on the manufa ...

The proposed Autonmous Reactive Ferrrying Drifter (ARF-D) provides wide measured swath, autonomously maintains a buffer distance from close-shore snags, and by utilizing river flow provides a very low power approach to obtaining cross-river surveying, providing greater coverage with minimal power penalty. By randomizing the cross-river transit paths multiple ARF-D units will naturally overcome the ...

The Navy is developing an electromagnetic (EM) launcher for long-range naval surface-fire-support. Severe operating conditions of the EM system place stringent requirements for materials, including high current and magnetic fields, high temperatures, contact with liquid metals, high stress/gouging from balloting contacts and high-speed-sliding electrical-contact with an Al armature. Engineered Coa ...

Nanotrons Corporation, in collaboration with Professor Byungki Kim at NSF Nanomanufacturing Research Center at the University of Massachusetts Lowell (UML), proposes to develop the low-cost high-rate manufacturing technique for flexible explosive detection sensors to significantly increase sensitivity of detection of trinitrotoluene (TNT) explosives. The new approach combines cutting-edge nanomate ...

Network-centric command and control of complex military missions (e.g., anti-submarine warfare, collaborative mine hunting, etc.) calls for cost-effective designs that can dynamically tradeoff multiple conflicting objectives. Often these optimizations have to be carried out at a higher level, and the associated control directives have to be disseminated down to a distributed system, thereby, influ ...

The exponential growth of text-based communication associated with the Internet has lead to a vast increase in the amount of unstructured messages that open source intelligence needs to process. This increase has lead to the need to develop methods for facilitating the detection of deception in various forms of text-based messages, from chat rooms, emails, weblogs, to text messaging. Methods are r ...

A broadband antenna, having more than a 100:1 bandwidth,is integrated with a high impedance surface that is compatible with the manufacturing processes associated with with Navy topside panel constructions and marine vehicle armor. The high impedance surface (also known as an artificial magnetic conductor, or AMC) can be tuned to discrete frequency bands using voltage-variable capacitors and the o ...

We propose to design a high average power Er:Fiber ultrafast laser system which is pumped at 14xxnm, and at the same time solve other problems related to ultrashort pulses in fiber lasers. The advantage of using 14xxnm pumping is the reduction of the standard quantum defect from 37% to 5%, thus greatly reducing the thermal load on the system, which makes it inherently more efficient. We also inten ...
