Air cushion vehicles (ACVs) have operated successfully on commercial routes for about twenty years. The routes are normally quite short; the craft are equipped with radar and radio navigation aids and maintain continuous contact with their terminals. Navigation of these craft, therefore, does not present any unusual difficulty. The introduction of air cushion vehicles into military service, however, can present a very different picture, especially when external navigation aids are not available and the craft must navigate by dead reckoning. This paper considers the problems involved when navigating a high-speed air cushion vehicle by dead reckoning in conditions of poor visibility. A method is presented to assess the ACV's navigational capability under these circumstances. A figure of merit is used to determine the sensitivity of factors which affect navigation such as the range of visibility, point-to-point distance, speed, turning radius and accuracy of onboard equipment. The method provides simplistic but adequate answers and can be used effectively to compare the-capability and cost of alternative navigation concepts.

A turning point occurred in naval engineering in 1972 when the U.S. N avy chose to use marine gas turbines for the propulsion of its new SPRUANCE and PERRY Class ships. This paper reviews the more than twenty years of experience with turbine technology and its design integration into combat ships needed to make that decision. It is concluded that the availability of a good second generation aircraft derivative engine with proven reliability and a strong commercial base, i.e., the LM-2500, was as important to the decision as was the predicted improved ship effectiveness and cost benefits. This paper discusses improvements that can be made to the twin engine, single gear, single propeller shaft system. Focusing only on this mechanical transmission concept, it addresses the impact of possible improvements to the engine, gear, and shafting. In particular, the paper discusses current LM-2500 related R&D efforts to: (a) obtain improved part-power fuel rates, (b) integrate with a reversing reduction gear, and (c) add on a waste heat recovery steam cycle. Looking ahead to the year 2000, this paper suggests that a successor to the ubiquitous LM-2500 will appear in the 15 MW power range to provide the next step in the evolution of the twin engine package. This new naval engine will most likely be based on an aircraft core that exists at present, such that it will have demonstrated its reliability and commercial potential through many hours of testing prior to its mid-1990 marine conversion. This new engine is expected to offer improved air flow, an excellent fuel rate (approaching a flat 0.30 LB/HP-HR), and effective maintenance monitoring, all at some expense in size, weight, and cost. The year 2000 engine will burn a liquid hydrocarbon fuel similar to JP-5 because of its aircraft origins. Combined with advances in gear and shafting technology, the full twin engine propulsion system of the year 2000 should be markedly lighter, smaller, and more efficient than today's units.

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.

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.

作者： DETOLLA, JP FLEMING, JR Joseph DeTolla:is a ship systems engineer in the Ship Systems Engineering Division SEA 56D5 at the Naval Sea Systems Command. His career with the Navy started in 1965 at the Philadelphia Naval Shipyard Design Division. In 1971 he transferred to the Naval Ship Engineering Center. He has held positions as a fluid systems design engineer and auxiliary systems design integration engineer. Mr. DeTolla has worked extensively in the synthesis and analysis of total energy systems notably the design development of the FFG-7 class waste heat recovery system. He is NA VSEA's machinery group computer supported design project coordinator and is managing the development of a machinery systems data base load forecasting algorithms and design analysis computer programs. Mr. DeTolla has a bachelor of science degree in mechanical engineering from Drexel University and a master of engineering administration degree from George Washington University. He is a registered professional engineer in the District of Columbia and has written several technical papers on waste heat recovery and energy conservation. Jeffrey Fleming:is a senior project engineer in the Energy R&D Office at the David Taylor Naval Ship R&D Center. In his current position as group leader for the future fleet energy conservation portion of the Navy's energy R&D program he is responsible for the identification and development of advanced components and subsystems which will lead to reductions in the fossil fuel consumption of future ships. Over the past several years he has also directed the development and application of total energy computer analysis techniques for the assessment of conventional and advanced shipboard machinery concepts. Mr. Fleming is a 1971 graduate electrical engineer of Virginia Polytechnic Institute and received his MS in electrical engineering from Johns Hopkins University in 1975. Mr. Fleming has authored various technical publications and was the recipient of the Severn Technical Society's “Best Technical Paper of the Year” award in 1

In support of the Navy's efforts to improve the energy usage of future ships and thereby to reduce fleet operating costs, a large scale computer model has been developed by the David Taylor Naval Ship Research and Development Center (DTNSRDC) to analyze the performance of shipboard energy systems for applications other than nuclear or oil-fired steam propulsion plants. This paper discusses the applications and utility of this computer program as a performance analysis tool for design of ship machinery systems. The program is a simulation model that performs a complete thermodynamic analysis of a user-specified energy system. It offers considerable flexibility in analyzing a variety of propulsion, electrical, and auxiliary plant configurations through a component building block structure. Component subroutines that model the performance of shipboard equipment such as engines, boilers, generators, and compressors are available from the program library. Component subroutines are selected and linked in the program to model the desired machinery plant functional configurations. The operation of the defined shipboard energy system may then be simulated over a user-specified scenario of temperature, time, and load profiles. The program output furnishes information on component operating characteristics and fuel demands, which allows evaluation of the total system performance.

NAVAL ENGINEERS JOURNAL 1983年第3期95卷 51-62页

作者： SLEMON, CS ABBOTT, JW Charles S. Slemon:graduated from Brown University with an Sc.B. Degree in Physics and did graduate work in semiconductors at the School of Electrical Engineering Cornell University sity receiving an M.S. degree. In 1972 he received an NSF grant to study the temperature dependence of crystal structures and while at Cornell he developed various fabrication and testing techniques with new semiconductor compounds. Upon joining Tetra Tech Inc. in 1976 he established and is responsible for their fiberoptic laboratory. He has carried out many programs involved in fiberoptic links for secure communication for various government agencies in which he authored numerous classified reports and developed special fiberoptic devices and system. He has also carried out studies and hardware development and evaluation programs for the military and commercial clients including marine and deep sea uses of fiberoptics for NOSC ONR and other off-shore industry contractors. For NAVSEA he authored several reports investigating the potential uses and advantages that fiberoptic technology offers to Navyshipboard operations. Mr. Slemon has published many articles and made numerous presentations in the field of fiberoptics. He has also taught several short courses on the subject and is the holder of several patents. Mr. Jack W. Abbott:received his BSME degree from Stanford University in 1960 and his Masters (MEA) degree from George Washington University in 1975. He holds a Professional Engineer License in the state of California. Mr. Abbott served as a naval officer – aboard a destroyer for 3 years. He worked for the Garrett Corporation for nearly 8 years involved with gas turbine design development and application. For the last 15 years Mr. Abbott has been directly involved with all aspects of destroyer design including the Canadian DDH 280 U.S. DD 963 and DD 993 destroyers. Currently Mr. Abbott is the NAVSEA Program Manager of the Ship Systems Engineering Standards (SSES) Program – responsible for developing combat system inter

This article introduces the concept of a truly Universal Signal Distribution Network. The emergence of fiberoptic technology as a viable signal transmission medium now gives the N avy the opportunity to use Fiber Optic Cabling and Switching (FOCAS) to implement a universal network. A FOCAS Network can handle all present or future shipboard signal distribution architectures such as point-to-point or data bus. Furthermore, compared to existing cable installations, this network offers lower cost through reduction of the number of cables, weight, and volume, freedom from interference and EMP effects, increased redundancy, and higher operational flexibility. In addition, it will easily satisfy all future expansion or changes in signal distribution by providing at least a ten fold increase in data rate capacity over existing electrical cabling. This last feature alone holds the potential for allowing upgrading and conversion of modern combat systems without need for adding new cabling in the ship. Along with the introduction of the concept of a Universal FOCAS network and its practical benefits and capabilities, this article presents a trade-off between the Radar Data Distribution Network on the FFG and an analogous FOCAS network. Though far from optimized, the resultant FOCAS network shows that the conversion of existing shipboard networks to FOCAS is straightforward and provides a reduction of at least 90% in cable volume and weight and lower cost in cable purchase and installation.

This paper provides a context within which the role of human factors engineering (HFE) for Naval ship design may be understood. HFE is defined and its history as part of engineering design teams is traced. The role of HFE in ship systems design is defined, and the HFE Technology for Ships program, managed by SEA 061R, is described. The rationale for inclusion of HFE in the design process is presented, the methodology whereby it is incorporated into the design process is detailed, methodology to assess the application of HFE is outlined, and the benefits that will accrue as a result of inclusion of HFE considerations in the design process are documented. The counterpoint to inclusion is illustrated through instances of design-induced human errors. A specific application of HFE in the acquisition process is illustrated through use of the Landing Craft, Air Cushion HFE program plan. The difficulties which may be encountered as the size of the target system expands are described. Potential roadblocks to the required incorporation of HFE are examined for their source and possible ameliorative steps.

He has had many diverse assignments involving surface ships and submarines during the past seventeen years. During his tour at Naval Shipyard Portsmouth (N.H.) he was Assistant Design Superintendent and responsible for the introduction of Heat Recoverable Coupling technology into the shipyard. Presently he is assigned to the Naval Sea Systems Command (NAVSEA) in the Sonar Dome Office. Prior assignments within NAVSEA have been as Assistant Ship Systems Design Manager for the SSNX and FA-SSN preliminary designs in the Submarine Propulsion Analysis Branch in the Submarine Hydrodynamics Branch and in the Gear Coupling and Clutch Branch. He received his Bachelor of Engineering degree from Vanderbilt University in 1971 and in 1977 graduated from Massachusetts Institute of Technology with his M.S. degree in Naval Architecture and Marine Engineering and his Professional degree of Ocean Engineer. A member of ASNE since 1975 LCdr. Liberatore also is a member of IEEE SNAME the Naval Institute and Sigma Xi. Cdr. James E.

Although Heat Recoverable Couplings (HRCs), used to join pipe, may be labeled innovative “state-of-the-art” technology for U.S. Naval Shipyards, they have been in use in foreign ships and high technology industries for over a decade. HRCs provide a permanent leak-proof pipe joint in specified applications without the use of high temperature and the inherent hazards of an open flame. Manufactured from NITINOL, a nickel-titanium alloy developed by the U.S. Navy, the couplings exhibit a “shape memory” characteristic. That is, they return (shrink) to a specified shape (pipe diameter) thus forming a mechanical seal when the expanded coupling is removed from a cryogenic environment and warmed above approximately —130°C. This paper provides background information into the development of NITINOL, technical explanation of shape memory metallurgy, and a summary of results, with specific examples, describing the trial use of HRCs at Pearl Harbor and Norfolk Naval Shipyards. Limited return cost data and recommendations for future use are presented. Then, using the HRC program as a basis, the Authors discuss the conservative nature of the ship repair and maintenance environment. This environment, in the Authors' opinion, couples with complex contractual constraints and requirements which serve to restrict the introduction of new ideas. An analogy is made to Russian tenacity of recent years which promotes “exploring and doing” while we in the U.S. Navy are frequently content to study.

NAVAL ENGINEERS JOURNAL 1982年第2期94卷 179-199页

作者： THOMPSON, DH THORELL, LM Daniel H. Thompson Jr.:is a native of Louisville Kentucky. He graduated from Webb Institute of Naval Architecture in 1957. He was an Engineering Duty Officer in theUNITED STATES NAVYprimarily in the Far East responsible for ship repair and overhaul. He joined Sparkman & Stephens Inc. New York City as Assistant to the Chief Engineer in 1963 and worked on commercial military and private contracts. He has worked for Bath Iron Works since 1967. Between 1967 and 1971 he served first as Project Engineer on the DLG-16 Class Ship Modernization Program which involved eight ships and later as the Assistant to the Production Manager when he assumed the responsibilities for production management administration and sea trial coordination. He organized and directed cost reduction programs and led the development of a comprehensive management administration information system. Between 1971 and 1972 Mr. Thompson served as the Facilities Project Manager responsible for the execution of a nine million dollar shipyard facilities improvement program. In 1972 Mr. Thompson was appointed as the Producibility Assurance Manager for the FFG-7 Program. In this capacity he reviewed the detail design work and coordinated the early activities of the subcontractor responsible for detail design. He was also responsible for the development of the FFG-7 Class Producibility Assurance Manual which provided guidance to the detail designers on production/design integration. During the DG-47 (now CG-47) studies at BIW Mr. Thompson served as the Deputy Program Manager for DG-47 Technical Characterization in 1977. At present Mr. Thompson is working as a Project Engineer in the Technical Department. He is responsible for coordinating the engineering work on new DDGX and Variable Payload Ship projects. On special assignment he is also supporting the Cost Reduction Program at BIW as Chairman of the Technical Committee. Mr. Thompson is a member of SNAME and ASNE and is a licensed professional engineer in New York and Maine. Len Thorell:is a

The decoupling of combat systems from the platform makes it possible for shipyards and combat system suppliers to work in parallel without schedule or technological conflict. Great benefit is derived from building one, standard platform able to accommodate a variety of combat systems. The capability to build and test the payload modules independently, in a well equipped shore-based facility, means higher production efficiency and improved quality control. The standardization of payload-platform interfaces means that the detail design and construction of foundations and distributive systems need not be delayed if some of the combat system components are being upgraded at the time when the ship is in construction. Additionally, shipyards recognize the value of the variable payload ship concept for major combat systems and weapons upgrades. Analysis shows that combat system changes will not lie on the critical path from a scheduling point of view if the payload items are modularized and conform to the Ship systems engineering Standards. The shipyards intend to participate actively in the conservation of tenth-scale models and full-scale mock-ups. These mock-ups should prove valuable in the definition of interface requirements which must be incorporated in the Ship system engineering Standards. The module installation procedures and clearance requirements for both weapons modules and pelletized electronics can be checked in this effective way. Variable payload ship platform construction poses no technical problems as far as new facility requirements are concerned. Shipyards interested in assembling, testing, and installing payload modules would, however, have to use appropriate buildings, equipment, and cranes. These capital requirements are significant but reasonable for those yards that are likely to be interested in building frigates, destroyers, or cruisers. Furthermore, these yards generally plan for production improvements through better facilities, many of which

David Kazal:graduated from Colorado A&M from which he received his B.S. degree in Mechanical Engineering in 1951. Currently he is employed by the Ingalls Shipbuilding Division Litton Systems as a Project Engineer on the CG 47 Class Ship Program. During World War II he served in the U.S. Navy in Submarines. Mr. Kazal is a member of the American Society of Mechanical Engineers (ASME). Mr. Donald B. Campbell Jr.: received his B.S. degree in Electrical Engineering from North Carolina State University in 1961. He has over twenty-three years of professional experience in Ship Electronics System Engineering and was formerly a member of the Electrical Design Division at Newport News Shipbuilding. Additionally he was involved in quantification and evaluation of contractor shipbuilding claims against the U.S. Navy while he was employed by Booz-Allen Applied Research. Currently he is a Senior Member of the Engineering Staff at RCA providing program and engineering coordination for the AEGIS Program. Mr. Maurice W. Haff:received his B.S. degree in Electrical Engineering from Oklahoma State University in 1970.

While he was involved with “Design Budgeting” for the CG 47 from the beginning of the program as a Project Engineer Mr.

Traditional ship acquisition practices no longer support the requirements of today's shipbuilding programs. These practices require development of major combat and ship systems to be essentially complete prior to issuance by the government of the Request For Proposal (RFP) for ship detail design and construction. With the need for timely delivery of warships equipped with the most modern weapon systems possible, and maximum remaining years of functional effectiveness after delivery becoming increasingly important, new acquisition strategies are essential. “Design Budgeting,” an innovative new Navy acquisition and design strategy, is now a proven concept. Developed and implemented by the AEGIS Shipbuilding Project, it has been explored in depth with the Shipbuilding Industry as an alternative acquisition process that enables Combat system development and ship acquisition to proceed concurrently. Applied for the first time in the acquisition of Ticonderoga (CG-47), its use permitted development of major portions of the AEGIS Combat system (later to be Government Furnished Equipment to the shipbuilder) to continue well into ship detail design and construction without impact on overall schedules. Hundreds of changes to the ship engineering baseline which resulted from continued development and test of Combat system, were incorporated into the shipbuilding contract with no cost increase or delay and disruption of the shipbuilding schedule. Proven, adaptable, and available now, “Design Budgeting” is an acquisition and design strategy than can satisfy the requirements of current and future shipbuilding programs.
