The Minimal Manual was designed to address difficulties people have with state-of-the-art self-instruction manuals in learning to use powerful computing devices. It is briefer;it helps learners to coordinate their attention between the system and the manual;it specifically trains error recognition and recovery;it better supports reference use after training. In two experiments, the Minimal Manual was shown to afford more efficient learning progress than an otherwise comparable, commercially developed self-instruction manual, and was superior in the specific areas predicted by its design. © 1987, Taylor & Francis Group, LLC.

Mr. Adamson is a member of ASME and ASNE having previously served as secretary for the Flagship Section and as a member of the ASNE Day Papers Committee. He has had several technical papers published in the Naval Engineers Journal as well as in other technical journals and books. He holds a bachelor of mechanical engineering degree (1962) and a master of science in mechanical engineering degree (1966) from Georgia Institute of Technology and a master of science in governmental administration from George Washington University (1969). He is a registered professional engineer in the State of Maryland. Ronald W. Schutz:received his B. S. (Cum Laude) and M. S. degrees in inorganic electrochemistry from Rensselaer Polytechnic Institute in Troy New York. He is a recipient of the 1981 A. B. Campbell Award for young authors from the National Association of Corrosion Engineers. He has eleven years experience with corrosion research product development and industrial application of titanium alloys. He has presented and published more than twenty technical papers including reference handbook articles on the subject of titanium corrosion behavior and related application guidelines. He currently holds position of supervisor industrial product development and corrosion research at TIMET Corp. Division of TMCA Henderson Nevada. Mr. Schutz is a member of ASTM and NACE.

Titanium alloys are evaluated as an alternative to the current copper-nickel components now employee in U.S. Navy surface ship seawater cooling systems. Titanium offers a solution to the accelerated seawater corrosion and erosion related attack being experienced in seawater systems aboard CG-47 class cruisers as well as other ship classes and can provide a means for extending service life and substantially improving reliability. Both the positive and potentially negative aspects of utilizing titanium in piping and heat exchangers are reviewed. Titanium's excellent resistance to corrosion and erosion attack, good yield strength and relatively low density permit use of thinner-walled, reduced diameter piping and heat exchanger tubing (relative to copper-nickel) and thus offer reduced system weight and volume. System design strategies are discussed for eliminating or greatly mitigating the adverse effects of galvanic corrosion and marine biofouling, the two major concerns when applying titanium in seawater piping and heat exchanger systems. An overall assessment of titanium versus copper-nickel alloys is provided with regard to piping and heat exchanger fabrication, cost, performance, design criteria, piping component (valves, pumps, etc.) selection criteria, and operational limitations. Specific topics addressed as part of that assessment include: (1) shipyard fabricability of titanium piping systems and onboard repair; (2) biofouling experience and biofouling control techniques with titanium in seawater; (3) galvanic corrosion effects when titanium is coupled to active (less noble) metals and the strategies for eliminating the risk of galvanic attack. The viability of titanium for surface ship seawater systems is summarized, and areas of future work are discussed with the intent of providing guidance for successful application of titanium in shipboard seawater systems.

This paper discusses the need and processes for designing warships to meet cost constraints and for managing warship acquisition programs during the design phase to assure effective adherence to production cost constraints by the design team. The resource control methodology used during the contract design of the Arleigh Burke class destroyer, DDG-51, is examined as a potential model for controlling the cost while maintaining the combat effectiveness of warships. The paper begins with a summary of the basic issue — the relationship among unit cost, unit capability, force level numbers, and force capability — showing recent trends in destroyer costs and force levels. This introduction also includes a discussion of the cost constraint for the DDG-51 in relation to historical trends and ship construction funding allocation. The resource control methodology used to reduce and control costs of the DDG-51 is discussed with a summary of the approach, key concepts and tools, chronology of key events, examples, and results achieved. A number of observations on this methodology are then made which are followed by comments on life cycle costs. The paper concludes with remarks on the future application of the resource control methodology and areas for further work to improve future resource control efforts.

Algebraic aspects of linear control system stability

Algebraic aspects of linear control system stability

引用

IEEE Conference on Decision and control

作者： Carl N. Nett Department of Electrical Computer and Systems Engineering Rensselaer Polytechnic Institute Troy NY USA Corporate Research & Development Center Control Technology Branch General Electric Company Limited Schenectady NY USA

In this paper the problem of linear control system stability is formulated in very general terms and then resolved by (i) establishing a necessary and sufficient condition for stability, (ii) exploring in some detail the nature of this condition, and (iii) developing a parametric characterization of all controllers which stabilize a given plant. The problem formulation developed herein is based on a ring theoretic setting for linear systems, and is distinguished by the use of a novel control system configuration. Any interconnection of two distinct systems can be represented in terms of this configuration while preserving the distinction between the two systems. Moreover, no other configuration has this property. Benefits and extensions accrued as a result of this property are thoroughly discussed, as are some promising directions for future research.

He has been employed at the David W Taylor Naval Ship Research and Development Center Annapolis Maryland since 1957 and presently conducts research and development in shipboard auxiliary machinery including desalination and water recovery equipment heat exchangers and steam condensers. He is a registered Professional Engineer in the state of Maryland and in addition to ASNE which he joined in 1967 he is a member of ASME. Joseph F. Pizzino:received his BS degree in chemical engineering from the University of Maryland in 1970 and his MS degree in chemical engineering from The Catholic University of America in 1978. He has been employed at the David W. Taylor Naval Ship Research and Development Center Annapolis Maryland since 1971 and is currently involved in the development of reverse osmosis for shipboard desalination and liferaft emergency desalination. In addition to ASNE which he joined in 1974 he is a member of AIChE. Wilbur L. Smith:received his BS degree in mechanical engineering from the Virginia Polytechnic Institute in 1962 and has done graduate work at Pennsylvania State University and George Washington University in automatic control theory and systems engineering. His career with the U.S. Navy started at the Philadelphia Naval Shipyard in 1962 as a designer of hydraulic systems. He worked for the Naval Boiler and Turbine Laboratory as a boiler control system engineer from 1964 until 1968. Since then he has been employed by the Naval Sea Systems Command and is currently head of the Heat Exchanger Branch Code 56X23.

As part of a program to develop reverse osmosis (RO) desalination systems for shipboard freshwater production, the David Taylor Naval Ship research and development Center worked with the Naval Sea systems Command to install a 12,000 gal/day, two-stage RO plant aboard USS Fletcher (DD 992) in 1981. The first stage provides potable water (less than 500 parts/million total dissolved solids) for crew needs; the second stage provides high purity water (less than 2 parts/million of total dissolved solids) for boiler makeup. The plant has been producing acceptable water quality and quantity despite some materials related problems. The system design has proven to be well suited for minimizing manning and maintenance requirements. A 12,000 gal/day “ship quality” RO system is now under contract to meet Navy needs for a reliable, minimum weight and volume, low energy desalination plant for future surface ships. The preproduction plant will be required to meet stringent reliability requirements as well as shock, vibration, and noise specifications as part of the process for obtaining approval for full production. This paper describes the technology developments necessary to achieve the present naval performance levels and discusses plans for future applications.

TECHNICAL EVALUATION OF THE SES-200 HIGH LENGTH-TO-BEAM SURFACE EFFECT SHIP

引用

NAVAL ENGINEERS JOURNAL 1984年第3期96卷 77-93页

作者： ADAMS, JD BEVERLY, WF John D. Adams:is currently Manager of Marine Programs at Maritime Dynamics Inc. Tacoma Washington. He received his B.S.E. degree in naval architecture and marine engineering from the University of Michigan in 1972. His professional career began at Stevens Institute of Technology working as a research engineer in the Davidson Laboratory where he conducted model test programs of both conventional and advanced ships. Some of his responsibilities included hydrodynamic model testing of the Navy SES-100A and SES-100B testcraft and the early 2000-ton and 3000-ton SES designs. In 1975 he accepted a position as Director of Maritime Dynamics' field activities at the USN Surface Effect Ship Test Facility where he had responsibility for SES-100A trials analysis. While at SESTF he directed several unique programs including the development of an experimental Ride Control System for the XR-1D SES testcraft. At his present position since 1982 Mr. Adams has directed the development of a production SES Ride Control System the SES-200 trial analysis and analytical research and design studies for SES. He is a member of ASNE and SNAME. Walter F. Beverly III:is Test Director of the lead Landing Craft Air Cushion for Bell Aerospace in Panama City Florida. He has worked with surface effect ships (SES) for over ten years in various roles: SESTF. Past assignments included: Technical Director of the Navy Surface Effect Ship Test Facility (SESTF) Project engineer on the world's fastest warship the SES-100B and Program Manager's representative and T&E manager for the 3KSES Program in San Diego. Prior to his involvement with SES he was a flight test engineer at the Naval Air Test Center Patuxent River Maryland and graduated from the USN Test Pilot School test project engineering curriculum. Mr. Beverly received his BS in aerospace engineering from Virginia Polytechnic Institute in 1970 and his MS in systems management from the University of Southern California in 1977. He is a member of the American Institute of Aeronautics and

Recent Navy surface effect ship (SES) research has been aimed at achieving efficient operation at task force speeds without compromising the SES advantage of operating at higher speeds. Results showed that this objective could be achieved by designing ships with higher length-to-beam ratios than the previous generation of Navy SES. These ships are typically referred to as “High Length-to-Beam SES”. This paper describes an extensive program undertaken by Naval Sea systems Command (NAVSEA) to validate this research and demonstrate high length-to-beam SES capabilities. Under this program a 110 ft commercial SES was procured and stretched from a length-to-beam of 2.65 to 4.25 by installing a 50 foot hull extension amidships. This ship is the SES-200; it is the only large high length-to-beam SES in the world. A brief history of the SES-200 is provided, and the use of standard marine construction and systems in this ship is described. A synopsis of the SES-200 Technical Evaluation Program completed in the Chesapeake Bay and Atlantic Ocean is given, and results of performance, seakeeping and maneuvering tests are presented. The effect of cushion length-to-beam proportions on both cushion wave making resistance and total SES resistance is explained. Performance test data are presented to show that the advantages of high length-to-beam design have been validated. Full power operation in heavy weather at all headings is demonstrated, and heavy weather motion responses are compared to Navy surface ship criteria to show that limits are satisfied for both high and low speed operation. Directional stability and maneuvering test results are cited for both normal operation and impaired situations. Implications of high length-to-beam technology relative to multithousand ton ship design are discussed. The speed and seakeeping capabilities that SES in this size range offer are indicated by scaling SES-200 test data.
