Active Control of Flexural Vibrations in Beams
The feasibility of using piezoelectric actuators to control the flexural oscillations of large structures in space is investigated. Flexural oscillations are excited by implusive loads...
Planetary Base Inflatable Form Construction
The use of the inflatable form (IF) structure has been practiced in the concrete industry for more than a decade. This article proposes the use of a double-walled IF for the Phase I construction...
Inflatable Form Construction in Space
In 1973, NASA launched Skylab 1 using a modified third stage of a Saturn V Rocket. This orbital workshop proved to be a success even though problems occurred. This article discusses the...
Containerless Coating Processes for Large Space Structures
Large space structures (LSS) in low earth orbit (LEO) must be able to withstand the deleterious effects of in situ ultraviolet radiation, atomic oxygen, and thermal-cycling-induced microcracking....
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...
Simulator for Telerobotic Assembly, Maintenance and Repair of Large Space Structures
A first approximation level computer simulator for telerobotic assembly of large space structures is described. Approach, methodology and initial results are presented. An example based...
Space Truss Construction Studies
The ACCESS Shuttle Flight Experiment, designed to evaluate EVA for on-orbit assembly of erectable truss structure, is reviewed and principal results are summarized. In addition, two on-going...
Space Artificial Gravity Facilities: An Approach to Their Construction
In the course of adaptation to a space microgravity environment, humans experience cardiovascular deconditioning, loss of muscle mass, and loss of bone minerals. One possible solution...
Adaptable Crew Facilities for Future Space Modules
This paper discusses life-size studies recently carried out on advanced crew accommodation features for future space module utilization. The studies are based on exploratory designs for...
Planar Space Structures
This paper describes a construction system which has a number of practical advantages for the development of space structures. It uses relatively thin materials folded into interpenetrated...
The Role of a Mobile Transporter in Large Space Structures Assembly and Maintenance
Large space structures require a vehicle to support assembly, operations, and maintenance. These vehicles may be designed for specific tasks or for general use throughout the life of the...
Preliminary Analysis of Fire Suppression Methods for the Space Station
The choice of a fire suppression system for the space station remains open. Several alternatives have been suggested, each with particular advantages and disadvantages. The problem is...
Survey of Soviet Space Welding Technology Development
Soviet engineers clearly recognize the potential value of welding for maintenance, repair, and fabrication of structures in space. The development of this technology has followed a steady...
The Role of Welding in Space Maintenance and Repair
The nature of future space missions will result in increased incidence of degradation, damage, and wear of critical or expensive hardware. In many terrestrial applications welding provides...
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...
Pacific Space Port
The concept of the Pacific Space Center advocated by Mr. Tetuso Kondo (member of the House of Representatives, former Director General of the Economic Planning Agency) and Dr. Tatsuo Yamanaka...
The Human Element in Space: Lessons from Antarctica
The human ability to adapt and perform in an extreme environment during periods of prolonged isolation is influenced by a number of social, cultural, and psychological parameters. These...
Space Operations - Care and Handling of Remains
On earth, effective methods have accommodated all functional and operational facilities and entities necessary for the handling of human remains. None have been overlooked or omitted....
A Space Station Millimeter Facility
The design and use of a large millimeter telescope for construction on the planned Space Station (a Space Station Millimeter Facility, SSMF) are described. Such a facility would have manifold...
Structural Art in the Lunar Environment
Building structures will be a necessary part of extending our presence on the moon. In designing and building these structures, aesthetic value will play a prominent role. History shows...
