This project will demonstrate the feasibility of extending the probabilistic design verification capabilities of the OpenMETA tool suite with probabilistic programming methods. These extensions will enable correct-by-construction design methodologies in the presence of component, system, environment, and epistemic uncertainties.The OpenMETA model- and component-based design tool suite for the manu ...

Solid oxide fuel cells have long suffered from degradation due to impurities in the fuel and complexities associated with dissimilar materials and high operating temperatures. This degradation lowers the usable cell power output and requires ancillary equipment for fuel sulfur removal and reformation. A unique microstructure for the tubular anode will be produced using a novel freeze-casting tec ...

It is increasingly difficult for companies to enter the spare parts business. To produce a spare part, the manufacturer must recreate the form, fit and function of the original part, which can be especially difficult with high strength forged metal parts. There are processes available to the forging engineer to recreate the geometry and material chemistry of original part; however, getting the par ...

S-RAM Dynamics (S-RAM) will design, fabricate, test and commercialize a transcritical CO2 refrigeration system using the recently invented S-RAM CO2 oil-less, integrated expander/compressor unit (ECU). This CO2 refrigeration system will be targeted for mobile military cold storage assets and commercial transportation refrigeration units. The refrigeration system will meet the specified space requi ...

ABSTRACT: With the tremendously successful Phase I effort, Third Dimension Technologies (TDT), in collaboration with Lockheed Martin, Rickard Consulting Group and APTUS, plans in Phase II to create, test and evaluate a gaming-based training and rehearsal environment known as the W3DGE (Warfighter 3D Gaming Environment). The Air Force has a need for a lower-cost, more deployable tactical training ...

The potential for solid fuel ramjets (SFRJ) has been demonstrated over the last 40 years. SRFJ"s have significantly higher impulse than rockets (Isp>1200 sec) making them a competitive solution for long range applications such as missiles, missile interceptors, high speed transport and space vehicle stages. Increasing the regression rate and the energy density of the fuel further improves the adva ...

ABSTRACT: The damage tolerance approach is used widely in aerospace industry and has a physics-based foundation in fracture mechanics. The fatigue crack growth rate can be determined by calculating the SIF and knowing empirically derived material parameters. Similitude is achieved for different loads, different crack sizes, and different crack shapes. The down side to fracture mechanics is that a ...

This STTR Phase I proposal proposes to design and develop reactive filter media using nanofiber technology to capture corrosion inducing particulate matter present in coastal region air. The fibrous filter media will be functionalized using ion exchange chemistry which is known to react with salt ions. The media will be characterized for its filtration performance, resistance to airflow, and dus ...

ABSTRACT: The Tai-Yang Research Company (TYRC) of Tallahassee, FL in collaboration with Dr. Justin Schwartz of the North Carolina State University (NCSU) in Raleigh, NC propose in this Phase 2 effort to develop the critical technologies necessary for the implementation and operation of an airborne high temperature superconductor (HTS) superconducting magnetic energy storage (SMES) device with par ...

Accurate Automation Corporation (AAC) has developed a new artificial neural network processor (NNP) based upon a sparse Multiple Instruction Multiple Data (MIMD) structure which is ideally suited for Electronic Warfare (EW) applications. The proposed research will investigate the use of the AAC NNP for EW applications such as emitter identification which is used in ELINT, ESM, and RWR receivers. T ...
