Nonterrestrial material processing and manufacturing of large space systems

Abstract: An attempt is made to provide pertinent and readily usable information on the extraterrestrial processing of materials and manufacturing of components and elements of these planned large space systems from preprocessed lunar materials which are made available at a processing and manufacturing site in space. Required facilities, equipment, machinery, energy and manpower are defined.

Manufacturing development of DC-10 advanced rudder

Abstract: The design, manufacture, and ground test activities during development of production methods for an advanced composite rudder for the DC-10 transport aircraft are described. The advanced composite aft rudder is satisfactory for airline service and a cost saving in a full production manufacturing mode is anticipated.

Alcoa wind turbines

Abstract: An overview of Alcoa's wind energy program is given with emphasis on the the development of a low cost, reliable Darrieus Vertical Axis Wind Turbine System. The design layouts and drawings for fabrication are now complete, while fabrication and installation to utilize the design are expected to begin shortly.

Engineering management in a multiple-(second- and third-level) matrix organization

Abstract: The functional organization is described together with several forms of matrix organizations which have been successfully implemented. Engineering management's responsibility and contribution to the work output when the engineering organization is also matrixed for a large program are somewhat different from that in either a functional or single-matrix organization. A program-oriented second- and third-level engineering management matrix is described which was used successfully to manage over 800 engineering personnel on several major programs. The responsibilities remaining with the functional engineering organization and those unique to the matrix organization are defined. Advantages and disadvantages of this concept are discussed together with the impact of people's behavior and the general increase of effectiveness of the company. Problems and snags in implementation and a before and after comparison, showing how things are improved by the matrix system, are also presented.

A normative price for a manufactured product: The SAMICS methodology. Volume 2: Analysis

Abstract: The Solar Array Manufacturing Industry Costing Standards provide standard formats, data, assumptions, and procedures for determining the price a hypothetical solar array manufacturer would have to be able to obtain in the market to realize a specified after-tax rate of return on equity for a specified level of production. The methodology and its theoretical background are presented. The model is sufficiently general to be used in any production-line manufacturing environment. Implementation of this methodology by the Solar Array Manufacturing Industry Simultation computer program is discussed.

Preliminary definition and characterization of a solar industrial process heat technology and manufacturing plant for the year 2000

Abstract: The findings and projections of this preliminary definition and characterization of a solar industrial process heat technology and manufacturing plant for the year 2000 indicate that the technology and the manufacturing would be significantly more sophisticated and expanded than exists in the solar industry today. The solar process heat technology is defined to be a parabolic trough collector system and to utilize a combination of the more advanced materials and components under current development. The manufacturing operations are projected to include glass-making, silvering, electroplating and plastic-forming, which, while standard industrial procedures, will be additions to or expansions of existing solar manufacturing plants. These integrated operations for the year 2000 solar facility will introduce important environmental residuals which will need to be managed and controlled to satisfy local, state, and federal environmental standards. It can be anticipated that the development and growth of the solar manufacturing industry across the nation can produce a shift in both economic activity and environmental impacts to the centers of solar energy utilization.

Optical systems engineering: a tutorial

Abstract: Optical systems engineering is just beginning to come of age. The combination of new metrology, new manufacturing techniques, computer based analytical tools, and the stimulus of several premier optical programs are leading toward a fuller and more complete exploitation of the systems engineering approach to the design, development, fabrication, and operation of high performance optical systems. Systems engineering which involves an integrated interdisciplinary approach to the development of systems is most appropriate for optics. The very high precision character of optics leads to very complex and subtle effects on optical system performance, resulting from structural, thermal dynamical, control system, and even manufacturing and assembly considerations. The systems engineering approach is thus more important to optical system development than most other types of systems. Optical systems are sufficiently unique that communication problems often occur among users, optical engineers, and the rest of the systems team. It is essential that the optics community provide leadership to resolve communication problems and fully formalize the field of optical systems engineering.

Single chip bubble memory packaging

Abstract: Single chip bubble memory packages are currently in production of Texas Instruments. The mechanical configuration of the packages and some of the assembly techniques will be shown in this paper. Thermal characteristics and magnetic shielding characteristics will be discussed to indicate the type of testing that is required to design an acceptable package. Finally environmental test results will be presented.

An economic analysis of a commercial approach to the design and fabrication of a space power system

Abstract: A commercial approach to the design and fabrication of an economical space power system is presented. Cost reductions are projected through the conceptual design of a 2 kW space power system built with the capability for having serviceability. The approach to system costing that is used takes into account both the constraints of operation in space and commercial production engineering approaches. The cost of this power system reflects a variety of cost/benefit tradeoffs that would reduce system cost as a function of system reliability requirements, complexity, and the impact of rigid specifications. A breakdown of the system design, documentation, fabrication, and reliability and quality assurance cost estimates are detailed.
