This paper addresses the ship, system and equipment design features, operational doctrine and training that has been developed to provide effective shipboard damage control. Both the ship and the sailor are addressed, since both are integral and interdependent components of the damage control "system." Also, the enhancements afforded to protection of personnel from the effects of conventional and nonconventional weapons are discussed. Finally, a brief look into the future is presented. With the shrinking defense budget and corresponding reduction in fleet size and ship manning, novel system designs and automated decision aids will be required to do the job.

In his present capacity he is involved in the development of metal matrix composite (MMC) materials for spacecraft and thermal management applications. Prior to this MMC work he was involved in the development of test methods and improvements for ordnance devices and materials. He is also involved with both the SDIO Materials and Structures Programs and with various Navy Manufacturing Technology Programs. He holds a bachelor of science in chemical engineering from the University of Maryland. Kevin Beasley:has been employed at the Naval Weapons Support Center Crane Indiana since 1981 and assigned to the Packaging Design Branch since 1986. There he specializes in U.S. Navy electronic hardware development. He graduated from Purdue University in 1981 with a bachelor degree in aeronautics and astronautics engineering. Currently he is pursuing a master's of mechanical engineering from Rose-Hulman Institute of Technology William De La Torre:at Research Opportunities Inc. (November 1987 - Present) has coordinated all projects applying composite materials to electronic packaging. In this capacity he has been the project engineer on two SBIR contracts that optimized the composite architecture for thermal planes in Navy standard electronic modules which have undergone system qualification tests at Naval Weapons Support Center. He has guided the development of coating materials and processes for composite thermal planes. He has devised experiments to demonstrate the thermal transfer characteristics of composite materials through infrared thermography and test fixtures simulating the standard electronic module environment. He holds a bachelor of science in technical management from Southern Illinois University.

This paper reviews: (1) Navy sponsorship of pitch graphite fiber development, and (2) assesses the impact of the high thermal conductivity fibers on future Navy applications. Navy exploratory development programs (6.2) have revealed potential applications in advanced system for graphite fiber reinforced composites: (1) electronic packaging, (2) satellite radiators, and (3) elevated temperature applications such as missiles. Thermal management in these applications can be improved through the development and use of high thermal conductivity graphite fibers. In electronic packaging, the thermal planes that conductively cool the Standard Electronic Module, Format E (SEM-E) printed wiring board require both high thermal conductivity and thermal expansion matching. For satellite radiators, the graphite fiber reinforced metals offer a zero coefficient of thermal expansion, with maximum specific modulus. The joints between titanium missile structures and their ceramic nose cones require thermal expansion control, but high thermal conductivity is also a distinct advantage. Pitch graphite fibers are now available with a thermal conductivity of 1000-1100 W/mK and a modulus of 130-140 msi. Significant growth toward the theoretical thermal conductivity of graphite, at 2400 W/mK, is possible. The benefits of these fiber properties are shown for applications that are either thermal expansion or thermal conductivity dependent.

The NATO Frigate Replacement for the 1990s (NFR-90) Project was a unique approach to naval ship design and acquisition. It would have been the first U.S. Navy surface combatant primarily designed by an international organization. As a planning scenario, up to 60 ships, including 18 for the U.S. Navy, were to be acquired by the eight participating nations, making it potentially the largest NATO project ever attempted. Approximately 1,000 man years over a 10-year period were invested in the project. The project was prematurely terminated in January 1990. Nevertheless, a significant amount of work had been completed;the basic design of the ship was firmly established by a preliminary design, the combat system was thoroughly studied, and the economics of the program were well established. This paper describes the project, the technical aspects of the ship and combat system design, its innovative features and significant economic advantages. The conclusions relative to Aegis vs. NFR-90 or NFR-90/ Aegis mix (Table 14) are the opinions of the authors and the estimates of associated costs have not been validated by the Naval Sea systems Command.

THE AUTHORS 6 ABSTRACT Shipboard weather deck ice removal is a laborious, time consuming, dangerous task. The current operational scenario consists of sailors wielding hickory baseball bats. This paper describes a viable alternative, the Electro-Expulsive Separation system (EESS), originally developed by NASA. EESS technology has been designed to remove ice from aircraft surfaces. Developmental testing, which led to acceptance of this new device, is discussed together with its theory of operation. The resultant aircraft applications are described. The need to adapt this aircraft technology for shipboard applications is recognized by the Navy, the Coast Guard, the State of Alaska, and the commercial shipbuilding industry. Fishing vessels risk sinking every winter due to excessive ice accumulation on their decks and superstructure. Navy and Coast Guard cold water operations have been hampered for centuries due to severe ice accumulation during inclement weather. With the encouragement and cooperation of the State of Alaska, an EESS test program was formulated and subsequently conducted aboard an Alaskan Resources vessel in the Bering Sea. This testing is described, with lessons learned. Future test programs are identified, requisite for successful adaptation of this technology to combat and commercial shipboard applications.

This paper sets forth computer systems architecture concepts for the combat system of the 2010–2030 timeframe that satisfy the needs of the next generation of surface combatants. It builds upon the current Aegis computer systems architecture, expanding that architecture while preserving, and adhering to, the Aegis fundamental principle of thorough systems engineering, dedicated to maintaining a well integrated, highly reliable, and easily operable combat system. The implementation of these proposed computer systems concepts in a coherent architecture would support the future battle force capable combat system and allow the expansion necessary to accommodate evolutionary changes in both the threat environment and the technology then available to effectively counter that threat. Changes to the current Aegis computer architecture must be carefully and effectively managed such that the fleet will retain its combat readiness capability at all times. This paper describes a possible transition approach for evolving the current Aegis computer architecture to a general architecture for the future. The proposed computer systems architecture concepts encompass the use of combinations of physically distributed, microprocessor-based computers, collocated with the equipment they support or embedded within the equipment itself. They draw heavily on widely used and available industry standards, including instruction set architectures (ISAs), backplane busses, microprocessors, computer programming languages and development environments, and local area networks (LANs). In this proposal, LANs, based on fiber optics, will provide the interconnection to support system expandability, redundancy, and higher data throughput rates. A system of cross connected LANs will support a high level of combat system integration, spanning the major warfare areas, and will facilitate the coordination and development of a coherent multi-warfare tactical picture supporting the future combatant command st

作者： S.I. Sagatun Marine System Engineering Laboratory University of New Hampshire USA Division of Marine System Design Department of Marine Engineering and Naval Architecture Norwegian Institute of Technology Norway

This paper describes a situation assessment system for an autonomous underwater vehicle (AUV). This system is a result of research on knowledge-based guidance systems applied to AUVs, which is currently taking place at the Marine system Engineering Laboratory, University of New Hampshire. This paper gives the reader some background on the project, an introduction to the MSEL KBS architecture, and a description of how the situation assessment system is implemented. In a dynamic world with a complex mission, a mobile robot needs the ability to analyze its environment and its situation. We call this situation assessment. Since unplanned situations will most likely occur, the robot will need some ability to perform qualitative reasoning on its situation, before it modifies its original plan. This qualitative reasoning implies a system capable of building and maintaining a model of the vehicle's environment and itself. It also involves use of data from several different sources (sensor fusion) and combining these data into more abstract terms.

Anticipated technological advances in the quieting of potential adversary submarines mandate the use of increasingly effective detection systems for U.S. ASW forces. Based on the assumptions that sonar will continue to be the primary means of detection and that the effectiveness of each individual sonar element will not change markedly, one must increase the projected area of the sonar array to improve its capability. The primary SSN mission of anti-submarine warfare will hence require increasing the hull area devoted to the primary sonar detection system. A revolutionary hull form is proposed that maximizes the area available for this purpose. The advantages and disadvantages of this hull form are discussed and feasibility study level design parameters and arrangements presented.

During the early 1980s the United States Coast Guard took delivery of three surface effect ships (SES) from Bell Halter, Inc. These 136-ton, 30-knot plus, aluminum hulled cutters were to be used primarily for drug interdiction in the southeastern United States. By early 1985, however, the full load weight of these cutters had grown to 150 long tons, and their top speed had dropped to below 23 knots in calm water. By mid-1985, operation of all three SESs was suspended to prevent possible catastrophic failure of their main engines. At this point, the USCG joined ranks with Textron Marine systems (then Bell Aerospace), and Detroit Diesel to analyze what had gone wrong, and to propose solutions to the problems encountered. From that beginning, the performance of the Coast Guard's SESs has steadily and dramatically improved until at present all three cutters are able to exceed their original performance specifications. This paper discusses the problems experienced with the SESs, including engine overloading, vibration, ride quality, seal wear, poor lift system performance, and metal cracking, along with the corrective actions taken to solve them. The cooperation between government and private industry, which made this dramatic turn-around in performance possible, is also explored. Lessons learned about SES technology are viewed in relation to the general experience of the Coast Guard with other types of high performance hull forms.

NAVAL ENGINEERS JOURNAL 1988年第1期100卷 45-52页

作者： EXELL, JR KILLINGER, A LCdr. John R. Excell: USN received a bachelor of architecture from the University of Michigan and a master of science degree in mechanical engineering from the U. S. Navy Postgraduate School. He was commissioned in 1973 serving first as damage control assistant aboard USSGuadalcanal(LPH-7) and later as commissioning main propulsion assistant on USSMerrill(DD-976). He became an engineering duty officer in 1979 and served at Norfolk Naval Shipyard as senior ship superintendent for six ships and later within the shipyard Design Department. In May 1984 LCdr. Exell was assigned to the DD-963 Class Special Projects Office as program manager for air system improvements including the bleed air and anti-ice systems. He recently completed the Defense Systems Management College Ft. Belvoir VA and returned to NavSea PMS 377 as deputy for strategic sealift programs. Arthur Killinger:graduated from the University of Maryland in 1968 with a bachelor of science degree in mechanical engineering. He joined MPR Associates Inc. working on submarine safety design reviews following the loss of USSScorpion(SSN 589). After two years in the U.S. Army Nuclear Reactor Program and a year as U.S. Army engineer maintenance advisor in the Republic of Vietnam he returned to MPR Associates Inc. in 1972. Since then he has worked on nuclear power plant projects for several electric utilities as well as submarine and surface ship overhaul and maintenance improvement programs for the U.S. Navy. Mr. Killinger is a member of the American Society of Naval Engineers and the American Society of Mechanical Engineers.

This paper describes the steps taken to simplify the gas turbine intake anti-ice systems on DD-963 and DDG-993 class ships. The anti-ice system was designed and built as fully-automatic protection against intake duct icing on main propulsion turbines and electric generator turbines. Operating experience with the system indicated that it was nonfunctional more than 60% of the time. The system's poor availability was caused by its complexity, lack of use, lack of spare parts, poor training and documentation, and design and material problems. A Navy Independent design Review Team (IDRT) reexamined the technical bases for installing an automatic anti-ice system and demonstrated that automatic control was not necessary for gas turbine intake duct anti-icing. A series of design review calculations and shipboard tests confirmed that anti-icing protection could be provided by manual control of installed butterfly valves feeding hot air to each turbine intake. The time from the IDRT design simplification recommendations to the first modification of the anti-ice system was less than one year. To date, half of the 30 of the 35 ships in the two classes have been modified. This system simplification will result in life cycle maintenance cost savings in excess of 13 million dollars. Future CG-47 class and DDG-51 class ships will include this simplified approach to anti-ice system design for gas turbine intakes.

The ever increasing complexity of ships coupled with cost, schedule, and resource constraints require innovative methods by the Naval Sea systems Command's ship design community to meet this challenge. This paper describes the effort by the NavSea Ship Arrangement design Division to dramatically improve its ship design capability by the use of a system of computer-based design tools called the General Arrangement design system. The General Arrangement design system (GADS) is based on the engineering requirements of the ship arrangement design process. GADS is currently being used as a production engineering tool. This paper is organized into two parts. Part I describes the General Arrangement design system, and Part II describes the general arrangement design methodology.
