Thermal Effects on Large Space Structures with Fixed Attitude
Radiation thermal effects are studied simultaneously on the orbital motion and axial deformation of a very large axially flexible space structure executing planar pitch motion around the...
The Second Generation Space Station
Several aspects of optimizing space operations have been examined to identify key components in establishing a more efficient space infrastructure. A second generation space station situated...
Solar Power Satellite - A Re-Visit
The United States should renew activities investigating the production of baseload electrical power for use on Earth from space. Technology change, world events, and the dictates of the...
Comparisons Between Space Facilities and Earth-Based Analogs
This presentation will focus on the design of planetary bases and space stations as based on comparative designs for facilities in analogous harsh and isolated environments here on Earth....
Power Systems for Production, Construction Life Support, and Operations in Space
As one looks forward to mankind's future in space, it becomes obvious that unprecedented amounts of power will be required for the exploration, colonization, and exploitation...
Nuclear Electric Propulsion for Near-Term Space Missions
Potential uses of nuclear electric propulsion (NEP) for earth-orbit, lunar, and martian missions are analyzed. NEP systems allow a higher payload mass fraction than chemical systems. NEP...
Solar Water Heater for NASA's Space Station
This paper describes an investigation of the feasibility of using a solar water heater for NASA's Space Station. During the investigation computer codes were developed to...
Indirect Solar Loading of Waste Heat Radiators
Waste heat from space based power systems must ultimately be radiated away into space. The local topology around the radiators must be considered from two standpoints: the scattering of...
The Liquid Droplet Radiator in Space: A Parametric Approach
This study is a parametric investigation of the performance and operating characteristics of a cylindrical Liquid Droplet Radiator (LDR) for use in space. The LDR system mass per heat...
Potential Application of Space Station Technology in Lunar Bases and Manned Mars Missions
To meet the goals of its Space Station program, NASA is developing a large set of improved space systems capabilities. In areas such as power generation and distribution, on-board data...
Retrofitting for a New Life in Power
Despite continued growth in energy demands, electric utilities in the U.S. aren't building many new powerplants these days, due to the economic and regulatory roadblocks they...
Air Power Boosts Utility Energy Supplies
Based in part on successful findings of tests, in which compressed air was stored in underground aquifers, Central Illinois Public Service engineers are investigating a type of pumped...
Water Supply Yields Power
During an overall renovation of the water supply system in Pittsfield, Mass. it was decided to bring water from three of the town's four reservoirs to a single treatment plant...
Sylmar HVDC Converter Station East Seismic Design
The Sylmar Converter Station East in Los Angeles receives power from the Northwest via the Pacific HVDC Intertie, a ?500 kV dc transmission line. At Sylmar, the energy is converted to...

Rehab for Filtration
Not all water treatment plants currently include filtration, but standards set forth in the Safe Drinking Water Act mandate it for surface-collected potable water. Objective is removal...
Seismic Design and Construction of Complex Civil Engineering Systems
This publication presents information about practices for planning, designing, and constructing civil engineering systems for mitigating earthquake effects. Concepts dealing with defining...
Western Consortium on Advanced Highway Technology
Establishment of a regional consortium of western states for purposes of defining long-term objectives and making common cause in the development of advanced highway technology was undertaken...
Artificial Recharge in Finland
There are four reasons for artificial recharge of ground water in Finland: 1. The replenishment of aquifers by lake water. 2. To use aquifers as part of surface water treatment process....
Distribution System Rehabilitation
Hackensack Water Company has had an on-going program of cleaning and lining its transmission mains to increase their capacity and lower its pumping costs. But by late 1986, the need to...
