In an era of fiscal austerity, downsizing and unforgiving pressure upon human and economic capital, it is an Augean task to identify resources for fresh and creative work. The realities of the day and the practical demands of more immediate fleet needs can often dictate higher priorities. Yet, the Navy must avoid eating its seed corn. Exercising both technical insight and management foresight, the fleet, the R&D community, the Office of the Chief of Naval Operations (OpNav) and the product engineering expertise of the Naval Surface Warfare Center (NSWC) are joined and underway with integrated efforts to marry new, fully demonstrated technologies and operational urgencies. Defense funding today cannot sponsor all work that can be mission-justified over the long term because budgets are insufficient to support product maturation within the classical development cycle. However, by rigorous technical filtering and astute engineering of both marketplace capabilities and currently available components, it is possible in a few select cases to compress and, in effect, integrate advanced development (6.3), engineering development (6.4), weapon procurement (WPN), ship construction (SCN), operation and maintenance (O&M,N) budgetary categories when fleet criticalities and technology opportunities can happily meet. In short, 6.3 funds can be applied directly to ''ripe gateways'' so modern technology is inserted into existing troubled or aging systems, sidestepping the lengthy, traditional development cycle and accelerating practical payoffs to recurrent fleet problems. To produce such constructive results has required a remarkable convergence of sponsor prescience and engineering workforce excellence. The paper describes, extensively, the philosophy of approach, transition strategy, polling of fleet needs, technology assessment, and management team requirements. The process for culling and selecting specific candidate tasks for SHARP sponsorship (matching operational need with t

An introduction to a rational development of transverse stability criteria for surface ships is presented in this paper. The development is based on a probabilistic analysis of the uncertainties associated with the design parameters involved in determining the transverse stability. Reliability methods are used for assessing and determining transverse stability of ships. These reliability methods address the uncertainties associated with the basic design variables that are involved in stability assessment and design. The sources of uncertainty in stability variables are presented, uncertainties associated with these basic random variables are summarized, different reliability assessment methods are described, a case study that shows the computation procedure using some of these methods is discussed for illustration purposes, and finally, conclusions and recommendations for further work in this area are presented.

The objectives of Human engineering (HE) are generally viewed as increasing human performance, reducing human error, enhancing personnel and equipment safety, and reducing training and related personnel costs. There are other benefits that are thoroughly consistent with the direction of the Navy of the future, chief among these is reduction of required numbers of personnel to operate and maintain Navy ships. The Naval Research Advisory Committee (NRAC) report on Man-Machine Technology in the Navy estimated that one of the benefits from increased application of man-machine technology to Navy ship design is personnel reduction as well as improving system availability, effectiveness, and safety The objective of this paper is to discuss aspects of the human engineering design of ships and systems that affect manning requirements, and impact human-performance and safety The paper will also discuss how the application of human engineering leads to improved performance, and crew safety, and reduced workload, all of which influence manning levels. Finally, the paper presents a discussion of tools and case studies of good human engineering design practices which reduce manning.

The study proposes a combination of the function points model for software estimation with the ADISSA methodology for systems analysis and design. This combined approach, which is supported by a software tool, enables one to estimate various software metrics, such as size, effort, and duration, in the early stages of systems development, by basing them on the products of a thorough system analysis and design process. © 1996 IEEE.

Jan Lindberg:is a physicist in the Transducers and Arrays Division of the Naval Undersea Warfare Center in New London Connecticut. He leads NUWC'S exploratory development efforts for transduction science and currently is spearheading an effort to introduce high-energy density active materials into tactical sonar systems. With the discovery of high temperature superconductivity he saw the potential benefit of integrating several emerging technologies and enticed American Superconductor Corp. to develop a high temperature superconducting transducer which resulted in the March 1993 demonstration of the world's first integrated high temperature superconducting device. Mr. Lindberg's current interests involve design of high power ultrasonic copolymer arrays characterization of

A low-frequency underwater acoustic transducer integrating high-temperature superconducting (HTS) coils and terbium-dysprosium (TbDy) magnetostrictive material was designed, fabricated and tested. This represents a novel application for high-temperature superconductivity and is a first example of an integrated system involving HTS coils cooled by a mechanical cryocooler. It also brings HTS technology together with a novel magnetic materials technology. The I-ITS coils were fabricated using react-and-wind BiSrCaCuO-2223 HTS wires. They produce a peak field of 0.1 Tesla at 50 K. A single-stage, Stirling-cycle cryocooler was used to cool the coils and the TbDy driver to cryogenic temperatures (50-65K). The coils provide an AC magnetic field superimposed on a DC bias field, which produces oscillatory strain within the magnetostrictive rod;this motion is transmitted through a cryostat to two head masses which project sound into the surrounding environment. High power acoustic output can be obtained by operating the transducer at its resonance frequencies of 520 Hz in air and 430 Hz underwater. This development demonstrates that, unlike low temperature superconductors, HTS wires can be considered for AC applications due to the low losses in these superconductors and the higher heat capacities of materials at temperatures above liquid helium.

NAVAL ENGINEERS JOURNAL 1996年第3期108卷 181-190页

作者： Belair, D Eagan, M [?]Doug Belair is the program manager for Advanced Programs in the Fleet Ballistic Missile/Shipboard business area at Lockheed Martin Defense Systems. He joined Defense Systems in 1979 with a Bachelor's degree in Computer Science and held a variety of positions in software and systems engineering throughout his early career. In 1985 Doug received a Master's degree in Industrial Management from the Krannert School of Management at Purdue University as part of a GE executive training program and has subsequently held increasingly complex and responsible engineering and program management positions associated with Fire Control System advanced development. Doug is currently responsible for new business opportunities and has received a number of awards including the inaugural Lockheed Martin NOVA award for technical excellence. He has been associated with the application of Off-the-Shelf products for mission critical applications since 1989 and has presented the subject often to both government and industry.

This paper describes a market driven life cycle methodology for application of off-the-shelf products and provides anecdotal lessons for each of the life cycle phases. In order to form a framework for further discussion, a model of the off-the-shelf marketplace is introduced to define a range of products from low cost commodities to high-end niche or specialty items. Within this framework, strategies are recommended for defining product requirements both technical and programmatic, surveying the market to find products that meet those requirements and then acceptance testing those products to ensure they do in fact perform as advertised. Recommendations are provided in the area of product tailoring, if tailoring is deemed a cost effective alternative to unique design. The pitfalls of managing ''off-the-shelf'' vendors as subcontractors during the tailoring phase is also described. Product procurement is defined to include not only those steps required to procure product quantities for deploy ment but also steps to ensure that those products meet the same requirements as those accepted during the selection phase. Three product support strategies are next described. The strategies range from a traditional ''commercial'' approach with support provided within the vendor's infrastructure to a more traditional ''military'' approach in which vendors are subcontracted to provide longer term support. Selection of the appropriate strategy is based on a balance of cost, desired product life and desired level of stability within the system configuration.

An analytic model for the performance evaluation of space-division asynchronous transfer mode (ATM) switches is presented. This model assumes that the switch has a fixed capacity of m, where 1/spl les/m/spl les/N (N is the number of trunks). Other important parameters include arrival rate and buffer sizes. Numerical solutions for the maximum throughput, cell delay, and cell loss probability are given with simulation being utilized in order to validate the analytic model. For independent and identical Bernoulli arrivals, the study shows that the contention processes can be modeled as discrete M/D/m (FIFO or Random) queues, while input queues can be modeled by Geom/G/1 queues, and the output queues are G/sup [X]//D/1 queues. A closed-form approximation for cell delay when m>2 is given. The result shows that the performance of switches with a small capacity can approach that of output queueing. The model and result can be used for switch design analysis and higher layer performance models.

Combat casualty simulation on shipboard electrical power systems (active demonstration)

引用

NAVAL ENGINEERS JOURNAL 1996年第3期108卷 335-339页

作者： Goodnow, MO Rumburg, JW [?]Michael O. Goodnow received a Bachelor of Science degree in Electrical Engineering from Virginia Polytechnic Institute in 1981 and a Master's degree in Engineering Management from The George Washington University in 1994. Mr. Goodnow worked for the Baltimore Gas and Electric Company in both the Electric Operations Department and the Electric Construction Department utilizing his background in electrical power until 1985 when he began to work for the Navy. For the past ten years he has been heavily involved in shipboard power distribution systems design and improvement. He has been the project manager of the Electric Power Survivability Program for the Naval Surface Warfare Center in Annapolis Maryland for the past five years. He is a member of IEEE.

For many years, electrical cable exposed to fragmentation was never taken into consideration in fault predictions for electrical power distribution systems. Testing, which began in 1990 by NSWC Annapolis under the Electrical Power Survivability program, to evaluate the effects of combat casualty on electrical power distribution systems, verified that a condition of multiple simultaneous faults could occur from typical weapons threats. Four phases of testing were performed to characterize damage to electrical power cables. These four testing phases were severing a single energized power cable, fragmenting multiple power cables fed from a single source and fragmenting multiple power cables fed from multiple sources. This paper reviews the various phases of testing conducted from the inception of the program and the test results.
