Processor speed has traditionally grown at a rate faster than that ofcommunication speed in computer and supercomputer networks, and it isexpected that this trend will continue even stronger, as we move into theexascale age in the upcoming decade. This has resulted in what is known asthe "communication gap" for communication-bound HPC applications: theircommunication-to-computation time-ratio is s ...

Guild Associates, Inc. proposes to develop and evaluate an active electrochemical sensor based residual life indicator (RLI) for adsorptive carbon filters. The sensing system of the RLI will operate by analyzing the electrochemical state of the carbon within the filter and evaluate the remaining adsorptive reactive capacities of the filter. The sensor design will be challenged against an array of ...

Cornerstone Research Group, Inc. (CRG), proposes to demonstrate feasibility in the reduction of noise attributed to drainage slots in jet engine acoustic liners. This will be accomplished through the development of design rules for optimum slot design and the implementation of adaptive material technologies. CRG proposes to bring this technology to a technology readiness level (TRL) 2 after the Ph ...

Advances in additive manufacturing have opened the door to affordable manufacturing of customized hardware components for meeting affordability goals and minimizing life cycle costs. Developing and offering a common, affordable, and efficiently packaged cryogenic propellant management solution for spacecraft and satellite systems would be openly welcomed within the industry.Leveraging years of AFA ...

Niobium alloy (C-103) reaction control system (RCS) chambers have been used on numerous NASA programs. However at elevated temperatures, the strength of C-103 decreases significantly. Higher strength niobium alloys have been developed, but these alloys lack the formability of C-103. Recently, Additive Manufacture (AM) of niobium and C-103 has been demonstrated using powder bed electron beam me ...

There is a significant gap between the properties of materials that are produced using the current 3D printing processes and the properties that are needed to support critical space systems. The polyetherimide/polycarbonate (PEI/PC) composite recently demonstrated on the ISS is a significant step forward in development, however, FDM with PEI/PC represents the current practical limits of AM in spa ...

The use of combinatorial methods is proposed to rapidly screen catalyst formulations for the advanced development of aqueous phase oxidation catalysts with greater activity than current catalysts at temperatures less than 100„aC and low pressure. To accomplish this goal, a large catalyst library will be prepared using seven noble metals at two concentrations on three supports. With a maximum of ...

A compact microgravity and hypogravity compatible vacuum device is proposed to provide medical suction and containment of extracted fluids. The proposed aspirator will draw up to 40 L/min of air and produce a nominal vacuum of 500-mm Hg, which is comparable to commercially available medical aspirators. The unit will also provide a means for separation and containment of up to 1000 mL of aspirate ...

Many existing or proposed NASA small propulsion systems and advanced scientific instruments will require high voltages at medium to high power levels to function. Such space power supplies are generally bulky and lossy and, as missions increasingly migrate to ever smaller platforms, there will be an increasing need to substantially reduce the size/weight costs of providing such on-board power acce ...

In contrast to the standard cold reservoir Variable Conductance Heat Pipe (VCHP) where for tight thermal control an electrical heater is used for the reservoir (wicked), Advanced Cooling Technologies, Inc (ACT) developed a hot reservoir VCHP with the reservoir thermally coupled to the evaporator. This novel feature will provide a tight temperature control capability without the need for control po ...
