作者： Sims, P PHILIP SIMS graduated from Webb Institute in 1971 and went to work for the Advanced Design Branch of the Naval Ship Engineering Center (now NAVSEA). He was part of the FFG 7 design team in 1972. From 1973 to 1975 he was involved in creating automated early stage aircraft carrier design procedures and performing carrier design studies as part of the Sea Based Air Study and CVV design. He returned to school in 1976 for a master's degree at MIT. The 1977–80 period was spent in updating the Navy's destroyer-cruiser early stage design procedures and conducting design studies for the CGN 41 the reserve FFX and the DDX (later DDG 51) projects. During this period he was also team leader on Surface Ship Concept Formulation (CONFORM) studies of new ships such as a heavy combatant and a survivable cruiser. From 1981–83 he was the naval architect on the BB 62 modernization/ reactivation and Ship Design Manager for the BB 61 and CA 134. He was a member of the NATO Staff Requirements Working Group for the NATO Frigate Replacement for the 1990s (NFR 90) and the principle naval architect on NFR 90 at NAVSEA. The early 1990s were spent on CGN DDG 993 and CG 47 modernization studies. He conducted Navy studies of the Arsenal Ship prior to the award to industry teams followed by review of the industry ships. He prepared destroyer/frigate studies as part of the Force Architecture phase of SC 21. In 1999 he started conducting the first pre-milestone A studies of JCC(X) and stayed with the program until its cancellation in 2003. He currently conducts comparative naval architecture studies and starting the very early work on the CG(X).

The new Italian battleship Leonardo Da Vinci suffered a severe fire in 1916 resulting in the ship capsizing in Taranto harbor. The ship was not destroyed but upside down. The Italian Navy thought she could be salvaged and returned to service. The chosen approach was to refloat the ship upside down. Superstructure was cut away under water and the turrets dropped to bottom of the harbor in order to reduce the draft enough to get the ship into a drydock. In drydock, the still bottom-up ship was prepared for being turned upright. The ship was taken out of the drydock and by weight additions plus selective flooding the ship was capsized again but this time coming upright. Two appendices to the paper describe other ships floating upside down and other approaches to righting capsized ships.

Future USN aircraft carrier analysis of alternatives

引用

NAVAL ENGINEERS JOURNAL 2000年第3期112卷 15-25页

作者： Raber, JD Perin, DA Mr. James D. Raber:received a master of science degree in naval architecture and marine engineering from the Massachusetts Institute of Technology in 1967. Since 1967 he has worked for the Navy Sea Systems Command (NAVSEA) and predecessor organizations in the area of early stage design of naval ships. Among the major USN programs he has supported are the FFG 7 and DDG 51. In the late ‘70s he was the NAVSEA representative to the CNO DDX Study Group which established the general requirements for the DDG 51 class. He has been active in international technical exchange programs for which he was awarded membership in the National Order of Merit by the Republic of France in 1992. Since early 1996 he has been the NAVSEA Ship Concept Team Leader for what is now the CVNX Program. Dr. David A. Perin:received a PhD in mathematics from the University of Michigan in 1971. He joined the Center for Naval Analyses in 1973 where he has led a wide variety of studies on naval warfare. From 1985 to 1987 he served as the CNA representative on the staff of Commander Striking Fleet Atlantic for which he was awarded a Defense Distinguished Service Medal. During the 1990s he has led formal analysis of alternatives for the LPD-17 F/A-18E/F and CVX. Currently he is the Director of the JCC(X) Analysis of Alternatives.

In March 1996, the Department of Defense established a new program, then known as CVX, to develop a new class of aircraft carrier that would eventually replace the Nimitz class. The first step in the concept develop was exploring a wide range of alternative design concepts in a formal study known as an Analysis of Alternatives (AOA), which assessed their cost and operational effectiveness. About 70 total ship studies were developed to explore the range of design features, including airwing size and type, propulsion type, ship mobility performance, and a variety of survivability features. The AOA also assessed the performance of and total ownership cost of a large number of potential subsystem technologies. This paper summarizes the total ship studies developed for the AOA describes the ship system performance and total ownership cost of these alternatives, and discusses the rationale for determining some of the primary system requirements. Thus, the paper will provide insight into the Navy's intentions for system requirements and features to be incorporated into the U.S. Navy's future aircraft carriers.

In this paper, a methodology and guidelines for applying risk methods in design and operation of maritime systems were developed and demonstrated using a case study of marine diesel generators. The methodology consists of several modules that include system definition based on functional and performance requirements, definition of dependencies among subsystems, data collection and reduction, reliability and risk analyses, and results reduction for use in decision analysis. The methodology was used to assess and analyze typical service diesel generators found onboard ships. The analysis included the generation of cut sets for the overall reliability of the system. The most likely failure scenarios were determined by demonstration as the failure of fuel supply components. The results are consistent with previous findings of the U.S. Coast Guard.

Joint Logistics Over The Shore operations in rough seas

引用

NAVAL ENGINEERS JOURNAL 1997年第3期109卷 385-393页

作者： Vaughters, TG Mardiros, MF Theodore G. Vaughters:has more than thirty years of engineering and program management experience in the development and testing of material handing hardware systems to transfer cargo from ship-to-shore from ship-to-ship and within both Navy and commercial ships. From 1967 to 1977 he was a supervisory naval architect at Hunters Point Naval Shipyard and Mare Island Naval Shipyard. In 1977 he joined his present organization and became office head in 1987. He has received numberous awards including the Meritorious Civilian Service Award for the management of a program which development a Ro/Ro ship offshore unloading facility. His department is currently engaged in a number of RDT&E logistics program which include environmental ligistics Navy logistics modeling and simulation mobile offshore bases sea based logistics strategic sealift joint service ligistics over the shore systems underway replenishment and shipboard cargo handling systems. Martin F. Mardiros:has been working on JLOTS related systems for eight years as a engineer at the Naval Surface Warfare Center Carderock Division. He has a B.S.E. degree in naval architecture from the University of Michigan He has participated in numberous JLOTS and JLOTS related exercises since 1988. Mr Mardiros has fielded a evaluation of full scale prototype sea state 3 JLOTS systems for evaluation and demonstration such as the Air Cushion Vehicle Landing Platform (ACVLAP) improved mooring and fendering systems for causeway ferries and motion mitigation sytems for the Roll-On/Roll-Off Discharge Facility. Mr. Mardiros recently headed up the JLOTS Sea State 3 Option Study which is being used by the Navy and Army to develop their JLOTS master plan.

Joint Logistics Over the Shore (JLOTS) operations involve the unloading of ships without the benefit of fixed port facilities. Container ships, roll-on/roll-off (Ro/Ro) ships, break bulk ships, heavy lift ships, and tankers are the most common merchant vessels utilized in JLOTS operations to transport military cargo. A major problem is that the current JLOTS system is inoperative in sea state 3 and greater conditions. When seas build above sea state 3 the motion and relative motion of lighters and ships create extremely dangerous conditions which preclude the movement of cargo. New technology is currently being developed by the Navy, Army and the Defense Advanced Research Projects Agency (DARPA) to improve JLOTS operations. Several new JLOTS subsystems were recently tested as part of an Office of the Secretary of Defense (OSD) sponsored joint services test and evaluation program called JLOTS III (June 1993). JLOTS III showed that lighters, cargo transfer systems, and personnel do not have the capability or training to perform in sea state 3, as currently required by military doctrine. Subsequent to the JLOTS III testing, a number of R&D innovations have been examined and a Heavy Weather (Sea State 3) JLOTS Options study has been completed. This options study has defined and characterized all the weak links related to heavy weather operations and has identified and/or developed concepts to improve the overall JLOTS operational efficiency. This paper discusses current JLOTS technology development initiatives from a joint services perspective with regard to the following question: Can emerging technology, in combination with improved training and command and control, provide a heavy weather JLOTS capability which is affordable?

New construction at the Boston Navy Yard, 1941-1945

引用

NAVAL ENGINEERS JOURNAL 1996年第4期108卷 59-75页

作者： Kern, DH Brown, JA Admiral James Andrew Brown USN(Ret.):entered the U.S. Naval Academy in 1932 graduating with a Bachelor of Science degree. After two years on a battleship in the Pacific he was ordered to MIT to study naval construction. He received his Master of Science degree from MIT in 1942 and immediately reported to the Boston Navy Yard where he was assigned to new construction. He remained on that assignment until 1945 when he was ordered to Pearl Harbor for duty with the Fleet Maintenance Office. Adm. Brown held many tours of duty including serving as professor of Naval Architecture at MIT with primary duties in connection with the officers assigned to the XIII-A Program. After a short tour as commanding officer of the Ship Repair Facility in Subic Bay he returned to Washington to head the Hull Design Division. During this tour many revolutionary ship designs were completed including the first nuclear surface ships the Skipjack and Polaris submarines. After tours at New York Naval Shipyard and as supervisor of shipbuilding at Camden New Jersey he reported to the Bureau of Ships as assistant chief of ships for shipbuilding design and maintenance. In 1965 he was assigned to commander Norfolk Naval Shipyard and supervisor of shipbuilding for the Fifth Naval District. After retirement he served for six years as vice president of a general contracting firm after which he worked as a contractor on Navy support and maintenance. As opportunities arise he now serves as a volunteer doing community work.

During World War II the Boston Navy Yard made significant contributions to the war effort. This yard produced record numbers of ships and craft considered vital for the support of our armed forces. Simultaneously the Yard accomplished repairs and completed alterations on large numbers of active ships so they could return to sea. Several ships were assigned to the Yard for major conversions. These accomplishments become more impressive when one recognizes the severe limitations in work area and basic and essential shipbuilding facilities that the shipyard's forces had to overcome.

To establish a planning basis for future avionics systems, the Naval Air Systems Command (NAVAIR) conducted an avionics architecture investigation during 1992-1993, culminating in a final report published in August 1993. In the course of the study, U.S. Industry provided significant information to a NAVAIR avionics database for both technologies and systems integration methods. From the study emerged an implementation strategy to allow NAVAIR to develop effective avionics systems in the future that use commercial products and standards where applicable but also allow the ready use of new and emerging technologies. Recommended strategies concentrate on the development process, especially the use of sound systems engineering techniques and the maximum practical use of commercial standards and products. This paper reviews the methodology employed during the NAVAIR investigation, and presents the key findings and resulting implementation strategies. The paper concludes with a brief summary of current implementation plans at NAVAIR.

Designing a world-wide satellite network that consists of hundreds of user sites and thousands of circuit connections is a complex problem, which involves selecting a set of candidate satellites and satellite beams/frequency bands from among numerous existing and planned satellites, evaluation of circuit connectivity, earth-station compatibility and sizing, and estimating transponder loading. The design process may also require assessment of the impact of a different set of satellites and modified user traffic requirements on the space segment, the earth-station types and quantity, and the total system cost. Although a conventional design approach based on link-by-link and site-by-site analysis provides accurate results, it is time-consuming and impractical for developing high-level network architectures in a time-constrained environment. A design technique is proposed which employs a set of rules for satellite network design, in combination with extensive databases of satellite parameters, earth-station parameters and user traffic requirements, to synthesize a network architecture. The technique is particularly useful for performing high-level trade-offs among alternative architectures in terms of space segment requirements, the number and type of earth-stations and overall system cost. Once the desired architecture has been selected, a detailed design may be developed using conventional methods.

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
