One of the most serious problems encountered in Naval steam plants following World War II was the unreliable performance of boiler and main feedpump pneumatic control systems. In addition to control component and system design deficiencies, these control systems suffered from inadequate methods to measure and adjust system alignment. This paper describes the development of a set of procedures for on-line alignment verification (OLV) of pneumatic main boiler and feedpump control systems. The procedures are designed for use by N avy control system technicians and, in addition to on-line alignment verification, provide guidance for troubleshooting and for performing system alignment. Procedure static checks measure steady state steaming performance and OLV procedure dynamic checks measure the ability of the boiler and control systems to respond to load changes. The paper describes typical control system characteristics that influence OLV procedure content and the supporting analysis that was used to establish alignment criteria ranges that satisfy both steady state and transient performance requirements. Also described is the alignment criteria tolerance analysis along with the steps involved in a typical OLV check procedure development. Descriptions of the various OLV checks, troubleshooting procedures and alignment procedures are provided. Typical shipboard implementation requirements are described and experience to date with the procedures is provided along with a status report on OLV procedure implementations.

NAVAL ENGINEERS JOURNAL 1982年第4期94卷 43-48页

作者： BARNETT, NJ CHENEY, SH Neal J. Barnett:holds a Bachelor of Mechanical Engineering degree from the City College of New York February 1967 and a Master of Science degree in Applied Mechanics from the Polytechnical Institute of Brooklyn May 1972. He is a member of Tau Beta Pi the National Engineering Honor Society Pi Tau Sigma the National Mechanical Engineering Honor Fraternity and the ASME the American Society of Mechanical Engineers. Mr. Barnett has been a civilian employee of the Navy Department since 1967 and is currently employed as a navigation systems engineer at the Naval Air Development Center Warminster Pa. For the past nine years Mr. Barnett has specialized in and has been technically responsible for the development of ship and submarine speed sensors for U.S. Navy Fleet applications. Samuel H. Cheney:holds a Bachelor of Science in Electrical Engineering degree from Drexel University Philadelphia Pa. June 1974 where he specialized in electronics and communications. He is a member of the Institute of Electrical and Electronics Engineers (IEEE). Mr. Cheney is currently employed as an Electronics Engineer at the Naval Air Development Center (NAVAIRDEVCEN) Warminster Pa. where he is currently assigned as Project Engineer for the High Speed Velocity Log Program prior to coming to NAVAIRDEVCEN in September 1977 he was employed by the Department of the Army Frankford Arsenal where he was involved in development of electronic fire control systems.

Advanced high speed ships (surface effect ships, hydrofoils and air cushioned vehicles) under development will operate at speeds which are considerably higher than conventionally hulled ships. Precise velocity sensing and measuring techniques that provide the required accuracy throughout their operating speed range do not currently exist. This paper will discuss the Navy's development of a High Speed Velocity Log (HSVL), which will provide self contained, two-axis velocity measurement for these advanced high speed hulls. The system selected by the Navy for an exploratory development program uses microwave doppler radar technology. The paper will discuss reasons why an FM-CW doppler radar technique was chosen over other candidate technologies. The doppler radar technique involves the transmission of narrow beam radar signals down toward the water surface. Frequency of backscattered energy from the water surface is compared with the frequency of transmission to determine the “doppler” frequency shift from which ship's velocity relative to the water surface is computed. The paper will present test results of the HSVL feasibility model aboard the hydrofoil USS High Point (PCH-1) and aboard the Amphibious Assault Landing Craft Jeff (B). In addition, a summary of an intensive analysis phase to determine HSVL critical design parameters will be described.

Dynamic Simulation is defined as the hardware and software required to present to the student operator visual and audible cues and responses that are the same as those encountered when operating the control Consoles aborad ship. This type of simulation is considered essential to the development of operator skills for critical tasks. Less critical tasks can be practiced using static simulation devices. This paper discusses the utilization of these types of training devices to train Navy crews. An overview of the Machinery control systems of the FFG 7 and AO 177 Class ships is discussed to provide an understanding of state‐of‐the‐art equipment development. The training programs for these two ship Classes are then reviewed to show how simulation devices are currently used by the Training Community, and this is followed by a brief discussion of the additional benefits that also are derived. © 1980 by the American Society of Naval Engineers, Inc.

As part of the Advanced Submarine control program (ASCOP), the Naval Sea systems Command has developed an open water Submarine control System Test Vehicle (CSTV). This vehicle is a 1/12 scale model of an SSN 688 Class Submarine, with provisions for easy geometric changes. Such changes include alternate Sail size and location, the addition of parallel middle-bodies, alternative tail sections, and alternative control configurations. A self-contained instrumentation and control system provides the capability for “on-board” recording of all relevant Submarine-state variables, over the entire speed and depth range, to a degree of data accuracy exceeding any known system. With the means thus available to correlate measured vehicle hydrodynamics with selected maneuvers, conditions, and changes in hull geometry and control surface configuration, modern mathematical techniques for improving submarine equations of motion can be employed to permit dramatic design enhancements in both safety and performance. This paper provides the rationale and history of the development of this vehicle, a description of the instrumentation and control package, and a description of the vehicle itself.

SHIPBOARD DATA MULTIPLEX SYSTEM - NEW CONCEPT FOR WARSHIP ELECTRONIC SYSTEM INTEGRATION

引用

NAVAL ENGINEERS JOURNAL 1979年第4期91卷 51-61页

作者： WAPNER, M THE AUTHOR graduated from the City College of the City University of New York from which he received both his Bachelor and Masters degrees in Electrical Engineering. He joined the Naval Applied Science Laboratory in 1961 where he served as Project Engineer for Ships Inertial Navigation Systems (SINS) and related equipments. Since 1967 he has been employed by the Naval Sea Systems Command (formerly NAVSHIPS) Research and Technology Directorate. initially as Navigation and Interior Communications Program Manager and currently as Director Combat Support Systems R&D Office. In addition to being the Program Manager for the Shipboard Data Multiplex System. his responsibilities include supervising research and development in areas of surveillance. fire control command and control and related command support functions. He is active in a number of U.S. Navy and foreign government information exchange programs has authored several technical papers and is a member of the Institute of Navigation and the Institute of Electrical and Electronic Engineers.

The Shipboard Data Multiplex System (SDMS) is a general purpose information transfer system directed toward fulfilling the internal data Intercommunication requirements of a variety of naval combatant ships and submarines in the 1980–1990 time frame. The need for a modern data transfer system of the size and capability of SDMS has been increase in unison with the sophistication of shipboard electronic equipment and the associated magnitude of equipment-to-equipment signal traffic. Instead of the miles of unique cabling that must be specifically designed for each ship, SDMS will meet information transfer needs with general-purpose multiplex cable that will be Installed according to a standard plan that does not vary with changes to the ship's electronics suite. Perhaps the greatest impact of SDMS will be the decoupling of ship subsystems from each other and from the ship. Standard multiplex interfaces will avoid the cost and delay of modifying subsystems to make them compatible. The ability to wire a new ship according to a standard multiplex cable plan, long before the ship subsystems are fully defined, frees both the ship and the subsystems to develop at their own pace, will allow compression of the development schedules and will provide ships with more advanced subsystems. This paper describes the SDMS system currently being developed by the U.S. Navy.

Facilities Maintenance (FM), as currently performed by shipboard personnel, requires a considerable expenditure of man—hours and material resources and is not performed efficiently nor effectively. Potential solutions to underlying problems were studied on portions of an operational ship of the FF 1052 Class. The study indicated that: 1) a significant reduction in man—hour expenditure and cost to the Navy is feasible through a systematic innovation program, 2) skill and knowledge of FM Team personnel is improved, and 3) shipboard spaces are cleaner and better maintained with FM innovations. The next phase of the project includes the total ship, and it is planned to commence in July 1978 aboard FF 1052, FFG 7, and LST 1179 Class ships. © 1978 American Society of Naval Engineers

An empirical heuristic learning identification algorithm of Ivakhnenko was modified and used to model an environmental system producing high nitrate levels in agricultural drain water in the Corn Belt. The method amounts to fitting a polynomial to a multi-input single-output response surface. The modifications result in a reduced number of terms in final model equations, a decrease in computational difficulties, and other improvements in the algorithm. This method appears to be advantageous with systems characterized by complexity with many variables and parameters, ill-defined mathematical structures, and limited data. In other words, this algorithm is useful for empirically generating hypotheses about systems of which relatively little is known. © 1975 IEEE. All rights reserved.

Richard Gauthey USN graduated from Cornell University in 1955 with a Bachelor of Mechanical Engineering degree and entered the U.S. Navy through the NROTC program. Following three tours of sea duty he attended the University of California at Berkeley where he earned his Master of Science degree. From 1963 to 1965 he was Project Officer for Aircraft Carriers and Amphibious Ships in the Design Division BUSHIPS. The succeeding three years he was Assistant Repair Superintendent for Surface Ships at the Pearl Harbor Naval Shipyard. After attending the Naval War College he was Maintenance Officer COMINELANT Staff prior to his present assignment as Director Ship Research and Technology Division NAVSHIPS where he has been since 1971. He is a member of both ASNE and SNAME. Joseph P. DeTolla a native of Philadelphia Pa. received his BS degree in Mechanical Engineering from Drexel University in 1969. He began his career with the U.S. Navy in 1965 as a Mechanical Engineering Trainee in the Philidelphia Naval Shipyard Design Division under the BUSHIPS Cooperative Education Training Program. In 1911 he joined NAVSEC as a Mechanical Engineer in the Fluid Systems Branch. For the past two years he has primarily been involved in conducting alternative auxiliary heating system “tradeoff” studies and in the design of total energy/waste heat recovery systems for the PF 109 Class Sea Control Ship DG/AEGIS and AO 177 Class. He is a registered Professional Engineer in the District of Columbia a member of ASE ASME and SNAME and a candidate for the Master of Engineering Administration degree at The George Washington University.

Energy used by U.S. Navy ships is viewed in the context of the national situation. Shipboard usage and the controlling variables are summarized. Research and development being planned by the Navy is described. Efforts relate to conservation of energy as well as consideration of new fuels including hydrogen and liquid hydro-carbon fuels derived from coal, oil shale, and tar sands. A brief account is given of work sponsored by the Department of Interior to produce hydrocarbon fuels, and initial Navy efforts to characterize and evaluate one such fuel is reported. This fuel has been burned at sea in the USS Johnston (DD 821). Development of conservation measures encompasses the utilization of waste heat from gas turbine and diesel engine exhausts and diesel water jackets; more efficient machinery; and reduction of energy requirements. Specific developments discussed include a design methodology to optimize waste heat utilization and higher efficiency gas turbine systems.
