Expert Systems as Applied to Future Space Transportation Syst

Future space transportation system programs must utilize cost reduction tools and techniques in order to become viable entities in the prevailing political and economic environments. Expert system and knowledge based technology can provide this opportunity for significant cost savings. Current active programs may achieve some limited cost benefits via piecemeal applications to identifiable worthwhile targets. But, the real value of the technology lies in the inclusion of its principles in the initial requirements definition phase for the target program and application of these principles throughout the program life cycle. Therefore, it is clear that accommodation of this kind of usage which encompasses the application of technology using sound engineering principles requires the development of tools to accommodate implementation. This means that expert system life cycle standards similar to MIL-STD 2167 are required, various expert system architectures must be developed, e.g., distributed and hybrid distributed systems, large and complex expert systems must easily integrate and interface with procedural language systems such as Ada, and tools that automate the process of knowledge base rule generation from domain experts must be developed to simplify the knowledge acquisition process. Development of these tools and capabilities is realizable within the capabilities of existing technologies. In the current environment of intensive development effort in pursuit of these tools and capabilities, it is reasonable to assume expert system technology will be in a condition suitable to support development of the next generation of space transportation system elements

Development of the Resource Module for the European Space Station Programme Columbus

This presentation summarizes the module during the study phases B1 May 1987. evolution of a resource and B2 from July 1985 to May The development has been performed by Dornier System on behalf of the European Space Agency ESA leading a consortium of 12 European companies. This summary shows the aim of establishing a design concept supposed to be most flexible with respeqt to changing mission scenarios as wel~ ~s different applications of the module. The presentation also shows the development of the design itself with emphasis on the present reference configuration. 1987

Advanced Air Conditioning Systems Developed from NASA Heat-Pipe Technology

This project exemplifies how NASA technology can be transferred to the market place in the scope of a Technology Utilization contract. In 1983, Dinh Company, a small R~D business, was trying to develop a S~lar Air Conditioner. Dinh Company conceived a Heat-Pipe system to increase the dehumidification of air conditioners therefore increasing their efficiency in providing comfort in humid climates. This l\u27esearch work attracted the attention of the TU officers at NASA/KSC who contacted Khanh Dinh, President of Dinh Company and started negotiations which resulted in a research contract whereas Dinh Company received from NASA technical support in the fields of Heat Pipes, Photovoltaics and Power Electronics. With this infusion of new technology, Dinh Company developed in a record time: a_High Efficiency air conditioner with one of the highest EER ratings today (EER; 15), an air conditioning system which removes twice more moisture out of the air, a Solar Powered Heat Pump, a Photovoltaic Tracking Generator, a line of low cost Digital Inverters. All of these products becoming commercially available in less than three year\u27s time
