THE OVERALL CYCLE EFFICIENCY (HENCE, INPUT POWER REQUIREMENTS) OF REVERSE-BRAYTON CRYOCOOLERS FOR SPACE APPLICATIONS IS HIGHLY SENSITIVE TO THE THERMAL EFFECTIVENESS OF THE HEAT EXCHANGERS. APPLICATIONS FOR THESE CRYOCOOLERS IN SPACE DICTATE THAT THESE HEAT EXCHANGERS BE AS SMALL AND LIGHT AS POSSIBLE. TO DATE, ONLYHEAT EXCHANGERS EMPLOYING ORGANIC MATERIALS HAVE BEEN ABLE TO ACHIEVE THE HIGH THER ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

Computational fluid dynamics (CFD) is used as an analysis tool to help the designer gain greater understanding of the fluid flow phenomena involved in the components being designed. The next step in the design process is to modify the design to improve the components performance, typically performed manually by the designer in a trial and error fashion. The innovations proposed herein will provide ...

Field emission electric propulsion (FEEP) thrusters have gained considerable attention for spacecrafts disturbance compensation because of excellent characteristics. The application of current FEEP has been slow in developing mainly caused by high specific power, which limit the milli-Newton thruster development due to insufficient onboard power. Dramatic field improvement from nanometer carbon ...

Supercritical air at cryogenic temperature is an attractive source of breathing air because of its very high density and low pressure. However, heat leak into the cryogenic tank causes the stored air to expand and vent, thus limiting the storage life of a charged system. We propose to develop a storage system for supercritical air packs that provides cryogenic cooling that will enable long-term ...

THIS PROPOSAL COVERS PHASE I OF A RESEARCH AND DEVELOPMENT PROJECT TO DEVELOP A LOW COST DISPOSABLE PASSIVE DOSIMETER FOR MONITORING PERSONNEL EXPOSURE TO TOXIC HYDRAZINE COMPOUNDS. THE SYSTEM WILL BE CAPABLE OF MEASURING IN THE WORKPLACE ATMOSPHERE AT LOW PPM LEVELS AND PROVIDING VISUAL ALARM WARNING TO THE WEARER. PHASE I CONSISTS OF THE NECESSARY BASIC RESEARCH INTO COLORIMETRIC CHEMICAL REACTI ...

THE FEASIBILITY OF A PROCESS CONCEPT TO MANUFACTURE SILICON,ALUMINUM, OTHER METALS, AND OXYGEN FROM LUNAR RESOURCES IS INVESTIGATED. FOCUS WILL BE ON A PROCESS STEP IN WHICH ALUMINUM METAL IS USED AS A REDUCTANT AND ON THE SEPARATION OF THE RESULTING PRODUCT.

Effective collective protection fabrics must have a reliable closure system. During our Phase I Work Plan, Sigma-K began developing a Hermetic Textile Closure Hardware (HATCH) system. The HATCH combines both a magnetic and geometric self locking mechanism that will provide a hermetic seal when closed. Our current Phase I successes include developing self closing samples that can provide a hermetic ...
