We propose to design and implement a query-based approach to interoperable modeling and simulation of composite material structures, that usually contain the manufacturing recipe within their design. In Phase I, we established the feasibility of the approach using a demonstration scenario of CAD/CAE interoperability for assemblies. In Phase II, we propose to develop a series of use-case scenarios ...

NASA is investigating advanced turboelectric aircraft propulsion systems that utilize superconducting motors to drive a number of distributed turbofans. Conventional electric motors are too large and heavy to be practical for this application, and so superconducting motors are required. In order to improve maneuverability of the aircraft, variable speed power converters would be required to thro ...

The requirement for cost effective manufacturing and metrology of large optical surfaces is instrumental for the success of future NASA programs such as LISA, WFIRST and IXO(now NGXO). OptiPro's UltraForm Finishing (UFF) is a sub-aperture compliant wheel and belt type polishing process for rapid material removal from the ground state to a finished optic. The UFF removes residual grinding sub-surfa ...

The protocols needed to coordinate the activities of distributed components, such as consensus algorithms, are notoriously difficult to design, implement, and verify. Abstraction is the only way to gain intellectual control over this complex problem; so ATC-NY and Cornell University have developed Event Logic, a high-level model for describing and reasoning about distributed systems, and EventML, ...

NASA space exploration missions require the electronics for avionic systems, components, and controllers that are capable of operating in the extreme temperature and radiation environments of space and planetary surfaces. To design wide-temperature, radiation-hardened (rad-hard) electronics and predict the characteristics and reliability in these extreme environments, advanced models and simulatio ...

The technical objective of this project is to develop a prototype of a face recognition application in a cloud computing environment utilizing MBARK as the middleware. The application will have a client piece that will run on a mobile device such as a laptop and a server piece that will run on a higher-performance computing cluster. The specific objectives of this development project can be enumer ...

The innovative High Efficiency, High Output Plastic Melt Waste Compactor (HEHO-PMWC) is a trash dewatering and volume reduction system that uses heat melt compaction to remove nearly 100% of water from trash and reduce the volume by up to 11 times. The HEHO-PMWC system incorporates novel methods to compress the trash, recover water, and remove the resultant plastic tiles. This system requires acce ...

CFDRC and TRLA are proposing to develop, design and test a highly scalable, mass-optimized inflatable structure that makes maximum utilization of materials in providing tailored stiffness and rigidity for hypersonic entry vehicles. The proposed inflatable structure is a hybrid pressure restraint vessel employing an impervious cloth-reinforced barrier structure enveloped by an integrated array of h ...

The liberation of particles induced by rocket plume flow from spacecraft landing on unprepared regolith of the Moon, Mars, and other destinations poses high mission risks for robotic and human exploration activities. This process occurs in a combination of "extreme environments" that combine low gravity, little or no atmosphere, with rocket exhaust gas flow that is supersonic and partially rarefie ...

Launch vehicles experience extreme acoustic loads during liftoff driven by the interaction of rocket plumes and plume-generated acoustic waves with ground structures. Currently employed predictive capabilities to model the complex turbulent plume physics are too dissipative to accurately resolve the propagation of acoustic waves throughout the launch environment. Higher fidelity liftoff acoustic a ...
