A fuel conservation study for transport aircraft utilizing advanced technology and hydrogen fuel

The conservation of fossil fuels in commercial aviation was investigated. Four categories of aircraft were selected for investigation: (1) conventional, medium range, low take-off gross weight; (2) conventional, long range, high take-off gross weights; (3) large take-off gross weight aircraft that might find future applications using both conventional and advanced technology; and (4) advanced technology aircraft of the future powered with liquid hydrogen fuel. It is concluded that the hydrogen fueled aircraft can perform at reduced size and gross weight the same payload/range mission as conventionally fueled aircraft.

Utility and technology for a space central power station

The technological and economical impacts of a large central power station in Earth orbit on the performance and cost of future spacecraft and their orbital-transfer systems are examined. It is shown that beaming power to remote users cannot be cost-effective if the central power station uses the same power generation system that would be readily available for provision of on-board power. Laser transmitters/receivers to make central power stations feasible are considered. The cost-effectiveness of meeting Earth-orbiting spacecraft electrical demands from a central power station was analyzed, indicating that this application cannot justify the investment required for the central station. Key technology needs which must be met to enable a viable central power station in the future are identified.

NASA/University Technology Cooperation

NASA is extensively engaged in cooperative technology development efforts with the nation's research universities. An example of NASA/university cooperation is the work of the Space Technology Center at the University of Kansas (KU) and the KU Center for Research, Inc. (CRINC). Directed by Professor Bill G. Barr, the Space Technology Center is one of 27 interdisciplinary centers established as part of a NASA plan to set up a network of advanced facilities across the nation. Since 1981 CRINC has been involved in a technology transfer program supported by the NASA Technology Utilization Division and by industry. The objective of the technology transfer program is to encourage industrial innovation through utilization of NASA technology through improved industry/university cooperation. At KU, research is conducted by the Industrial Innovation Laboratory and the Computer Integrated Manufacturing Laboratory which utilize graduate students in engineering and computer science as research assistants. A new project of the Space Technology Center is one designed to advance NASA objectives in "augmented telerobotics." A telerobot is programmed to respond to commands from a human operator, or to mimic the movements of its human operator. The project is being conducted under the guidance of Langley Research Center.

Utilization of remote sensing data - The sociological perspective

Remote sensing provides an opportunity to study the ways in which new sources of data enter into decisions related to resource management, the conditions and criteria for acceptance of the new techniques, and the methods by which assessment of their utility is accomplished. This article underscores the social dimensions of technology utilization and assessment, with reliability, specificity, ease of access, and openness among the main desiderata. The point is made that the interface between the technology and the society it is designed to serve is crucial, for upon its nature depend how, whether, when, and by whom the technology will be utilized. The present reliance on quantitative techniques, such as benefit-cost analyses, is reviewed from a sociological view point, and the inadequacy of these techniques is pointed out.

Efficient utilization of graphics technology for space animation

Efficient utilization of computer graphics technology has become a major investment in the work of aerospace engineers and mission designers. These new tools are having a significant impact in the development and analysis of complex tasks and procedures which must be prepared prior to actual space flight. Design and implementation of useful methods in applying these tools has evolved into a complex interaction of hardware, software, network, video and various user interfaces. Because few people can understand every aspect of this broad mix of technology, many specialists are required to build, train, maintain and adapt these tools to changing user needs. Researchers have set out to create systems where an engineering designer can easily work to achieve goals with a minimum of technological distraction. This was accomplished with high-performance flight simulation visual systems and supercomputer computational horsepower. Control throughout the creative process is judiciously applied while maintaining generality and ease of use to accommodate a wide variety of engineering needs.
