N/A

This proposal addresses the immediate need for models for accurate description of metal matrix composite (MMC) response to multiaxial loadings such as those existing in most turbine engine components. The model is needed for both design and life prediction of engine components. The proposed effort will result in a cost-effective method of predicting MMC response under multiaxial loading which will ...

N/A

The banning of Haon fire extinguishing agents has seriously compromised the effectiveness of fire protection for a number of aircraft applications. Efforts during the last five years have thus far identified alternative agents that have significantly reduced effectiveness (average +75% weight penalty), highter cost and ill-defined toxicologic properties. This Phase I program offers an affordable, ...

The banning of Halon fire extinguishing agents has seriously compromised the effectiveness of fire protection for a number of applications where they have been the 'universal' choice, especially on-board aircraft in habitable areas and 'fire zone' areas. Efforts have been underway by the chemical industry and various government agencies for the development of suitable alternative 'chemically' acti ...

N/A

The proposed innovation would do for the tip vortex what the turning vanes do at the inlet to gas turbine combustors, namely reduce the swirl. The intent of this proposal is to study the feasibility of the haney Swirler which consists of a set of vanes at the trailing edge of a downward curved tip, specifically a Sargent type tip. The standard wing tip would be modified to turn the outward flow do ...

IN THIS PROJECT, THE FEASIBILITY OF COMBINING SONIC DRILLING AND CONE PENETRATION TECHNOLOGIES WILL BE EVALUATED AND A SET OF PRELIMINARY DESIGN DRAWINGS DEVELOPED. SONIC DRILLING TECHNOLOGY HAS RECENTLY BEEN DEMONSTRATED AT THE HANFORD SITE, WA. THE RESULTS OF THE DEMONSTRATION PROVED THAT SMALL DIAMETER MONITORING WELLS COULD BE INSTALLED TO THE DESIRED DEPTH IN A RAPID MANNER USING THIS TECHN ...

Currently all oxygen used in USAF, Navy and US Army is produced by means of either cryogenic distillation (liquid oxygen) or pressure swing adsorption (PSA). Both methods have significant disadvantages. Currently employed PSA systems, in particular, are limited to 90-95% purity of oxygen produced. The intent of this proposed investigation is to develop a PSA process and system capable of efficient ...

It is difficult to exchange and use information between different office automation software tools. The user must spend excessive time learning and linking tools rather than doing the primary job. The proposed open framework expert system approach makes the technology of the tools transparent to the end user and allows the easy exchange and use of information from many databases, word processing, ...
