Settlements Induced By Soft Ground Tunneling, Miguel P. Romo

International Conference on Case Histories in Geotechnical Engineering

Ground settlements induced by air-pressure shield tunneling throughout the soft clays of Mexico City have been monitored in five test sections by means of settlement points installed at various depths and distances from the tunnel axis. Subsoil conditions and soil characteristics at each site were thoroughly studied in the field and in the laboratory. Measured settlement profiles have been compared to those computed by a simplified analytical procedure showing very good agreement.

Soil-Cement Backfill For Nuclear Power Plant Foundations, E. Saveri, G. P. Vaccaro, G. Varosio

International Conference on Case Histories in Geotechnical Engineering

Soil-cement backfills have been analyzed, designed and tested for the Alto Lazio Nuclear Power Plant in Italy. Extensive analyses were performed to evaluate the stability of and stresses in soil-cement foundation backfills. Soil-structure interaction was also analyzed. The minimum required cement content for foundation and general backfills was established and verified by means of laboratory and field tests. Foundation backfills were designed for two major buildings of the plant.

Subsidence Affects Due To Gypsum Solution In Syracuse, New York, G. W. Lee, S. P. Clemence, S. K. Bhatia, S. Anagnost

International Conference on Case Histories in Geotechnical Engineering

Two apartment buildings owned by Syracuse University in the Slocum Heights area underwent extensive differential settlement manifested by foundation cracks. Examination of rock exposures in the nearby area revealed the presence of gypsum beds. Onsite boring and investigation revealed that regrading and installation of french drains and storm sewers influenced the groundwater regime resulting in solutioning of the gypsum and subsequent collapse of underground cavities. Remedial measures included alteration of drainage system and underpinning of apartment structures.

The airline industry has been successfully transitionirg high technology equipment through these phase? both safely and economically. The technique? which they employ are being effectively applied to the Space Shuttle Program, as it enters the operational era.

Space Station Active Thermal Control Technical Considerations., Wilbert E. Ellis

Space Congress® Proceedings

A description of recent and planned thermal control technology developments at the Johnson Space Center and the other NASA Centers in support of Space Stations will be presented. The program is centered around satisfying the needs of the users. Preliminary results of proof-of-concept high capacity heat pipes and two-phase devices will be included which indicate that large amounts of enercy (100 kw) can be transported long distances (50m) with very small temperature differences. The presentation will summarize preparations for an "evolutionary test bed" for advanced development of thermal technology which will provide data on components and systems fcr incorporation into …

Payload On-Orbit'refueling Using The Sts, Donald A. Molgaare

Space Congress® Proceedings

The feasibility of performing an on-orbit refueling (OOR) operation to extend the orbital lifetime of the NASA Goddard Space Flight Center (GSFC) Gamma Ray Observatory (GRO) was investigated by TRW, the GRO mission contractor. This study shows that an OOR capability could be integrated into the GRO operational design early in the Phase D development with only minor cost impact and no schedule impact. In this approach, the GRO OOR design would be developed to achieve operational compatibility with the JSC/STS-developed Orbital Refueling System.

A Miniaturized Cassegrainian Concentrator Solar Array For High Power Space Applications., Robert E. Patterson, Richard M. Kurland

Space Congress® Proceedings

A miniaturized Cassegrainian concentrator (MCC) solar array system concept is under preliminary development for the space station or for other large spacecraft/space platform mission applications that may require power at the 100 kilowatt level or higher. The concept has many of the physical attributes of planar rigid-panel solar arrays and does not require unusual deployment or thermal management methods or auxiliaries. Furthermore, it promises both lower initial cost and lower life cycle cost than state-of-the-art lightweight planar flexible blanket solar arrays. The paper briefly describes the MCC concept and presents the results of a life cycle cost comparison analysis that …

Tracking Accelerating Spacecraft Signals With The Wide Dynamic Demodulator., Frank R. Leslie

Space Congress® Proceedings

The Wide Dynamics Demodulator (WDD) provides the capability to demodulate digital data received from an accelerating spacecraft, even during the high Doppler rates caused by booster engine firing.

The WDD is constructed around an internal microprocessor that receives highlevel commands from the external system computer, interprets them to select the optimum tuning, filtering, and operating modes, and reports status back to the external computer. The WDD will acquire a 35 MHz input signal with up to j^4200 Hz offset from the estimated frequency, and the frequency may be changing by as much as +8.2 Hz per second and at a …

Rescue In Space - Tdrs Flight 1, Emery I. Reeves

Space Congress® Proceedings

On 4 April 1983, the shuttle or biter Challenger released the Flight 1 spacecraft of trie Tracking and Data Relay Satellite System ITDRSS) and Its Inertial Upper Stage (IUS) booster In low altitude orbit. Altho perogee burn of the IDS was accomplished without incident, approximately threequarters of the way through the orbital injection burn, the IDS lost control. At the completion of the IUS burn, the spacecraft- IUS stack was tumbling violently in an anomalous eliptic orbit. During the succeeding hours spacecraft separation was accomplished and the spacecraft was stabilized and placed under positive attitude control. After assuring spacecraft safety …

Integrated Management, Orlan A. Soli

Space Congress® Proceedings

Progressive organizations recognize that it is not the business that competes but rather the managing team. They are aware that most managers fail for administrative, rather than technical incompetency. The good news is that the mastery of management can be learned end this is what this paper addresses. A growing, progressive organization experiences an evolution through several managing phases. The work effort of a manager can be generalized into two categories:

Managing People (obtaining results from employees)

Technical Work (obtaining results from hardware)

The Integration Gap i? defined as the difference between the actual and ideal distribution of the above …

Satellite Communications Network Control In The Presence Of Electronic Countermeasures, Marc Spellman

Space Congress® Proceedings

Satellite communications networks have supplanted other over-the-horizon communications systems because of their high capacity and high reliability. A key characteristic of satellite communications systems is that all communication links within a network share a common transponder and thus have the potential for deleterious interactions. This in turn gives rise to the need for a network control function that can establish and ensure appropriate transmission characteristics for each terminal with the goal of maximizing the communications capacity available to all network members.

Because of the potential for electronic countermeasures in military satellite communications systems, an antijam mode of operations, which by …

Shuttle Operations Era Planning For Flight Operations, John D. Holt, David A. Beckman

Space Congress® Proceedings

The Space Transportation System (STS) provides routine access to space for a wide range of customers in which cargos vary from single payloads on dedicated flights to multiple payloads that share Shuttle resources. This paper describes the flight operations planning process from payload introduction through flight assignment to execution of the payload objectives and the changes that have been introduced to improve that process. Particular attention is given to the factors that influence the amount of preflight preparation necessary to satisfy customer requirements. The partnership between the STS operations team and the customer is described in terms of their functions …
