sIMPLIFICATION OF GAs-TURBINE INTAKE ANTI-ICE sYsTEMs

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.

作者： RYAN, JC JONs, OP J. Christopher Ryan:earned his bachelor's and master's degrees in Naval Architecture from Webb Institute and MIT respectively. He spent three years at the Advanced Marine Technology Division of Litton Industries working on the DD-963 class ship design and related computer aided design projects. he subsequently went to the Navy Department concentrating on early stage design of surface combatants for 12 years including work on the FFG-7 Sea Control Ship CSGN and CVV aircraft carrier projects. He then shifted focus and became the technical director for the Computer Supported Design Program in NavSea for five years. Mr. Ryan has served in several supervisory positions within the Ship Design Group in NavSea since that time. He is currently the project manager for the Ship Design Acquisition and Construction Process Improvement Project. Otto P. Jons:received a Diplom Ing. in shipbuilding from the Technical University of Hannover W. Germany and an M.S. in naval architecture and marine engineering from the Massachusetts Institute of Technology in 1967. He then joined Litton Ship Systems where he was responsible for the preliminary design of the DD-963 hull structure and then for ship systems as manager LHA Ship Systems Engineering Department. From 1972 to 1974 he was principal research scientist at Hydronautics. In 1976 as technical director he helped establish the local office of Designers and Planners. Otto Jons was one of the co-founders of Advanced Marine Enterprises Inc. in 1976 where he is corporate vice president engineering.

In the spring of 1990, the Navsea Chief Engineer initiated a project to improve the design, acquisition and construction (DAC) of U.s. Navy ships. The project's objectives are to reduce the time and cost of acquiring and operating Navy ships while improving their quality, unlike previous studies on the subject, the project utilizes a rigorous process analysis approach and attempts to use quantitative measures as the basis for recommending improvements. The paper is, of necessity, a status report on the progress of this project. Topics covered include: the DAC process;a look at the current state of ship acquisition time, cost, and quality;the methodology for process improvements;and early findings.

To help health economic modelers respond to demands for greater use of complex systems models in public health. To propose identifiable features of such models and support researchers to plan public health modeling projects using these models. A working group of experts in complex systems modeling and economic evaluation was brought together to develop and jointly write guidance for the use of complex systems models for health economic analysis. The content of workshops was informed by a scoping review. A public health complex systems model for economic evaluation is defined as a quantitative, dynamic, non-linear model that incorporates feedback and interactions among model elements, in order to capture emergent outcomes and estimate health, economic and potentially other consequences to inform public policies. The guidance covers: when complex systems modeling is needed;principles for designing a complex systems model;and how to choose an appropriate modeling technique. This paper provides a definition to identify and characterize complex systems models for economic evaluations and proposes guidance on key aspects of the process for health economics analysis. This document will support the development of complex systems models, with impact on public health systems policy and decision making.

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.

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.

NAVAL ENGINEERs JOURNAL 1981年第4期93卷 29-37页

作者： HOPE, JP A native of Northern Virginia received his BS degree in Mechanical Engineering from the University of Virginia in 1969. Upon graduation he began his career with the Department of the Navy in the acquisition of patrol craft and submarine rescue ships at NA VSHIPS. In January 1971 he transferred to the Ship Arrangements Branch of NAVSEC. He was selected for the long-term training program at George Washington University in 1974 and completed the program in February 1976 with the degree of Master of Engineering Administration. While at NAVSEC Mr. Hope has been General Arrangement Task Leader on the AO 177 DDG 47 CSGN CSGN (VSTOL) CGN 9 (AEGIS) CGN 42 and assisted in the land- mark NA VSEA Civilian Professional Community Study. In 1978 he was selected as acting head of the Damage Control Section. From that position he was selected as acting head of the Surface Ship Hydrodynamic Section. In February 1980 he was promoted to head of the Surface Combatant Arrangements Design Section. In addition to numerous outstanding performance awards Mr. Hope was nominated for the Commander Naval Ship Engineering Center Professional Development A ward in both 1978 and 1979. In 1979 Mr. Hope was presented the National Capital Award for Professional Achievement (under age 36) by the District of Columbia Council of Engineering and Architectural Societies. Mr. Hope has presented numerous professional papers at ASNE and ASE Technical Symposia. Three of these papers have been published in the ASNE Naval Engineers Journal and his papers Management of Research and Engineering: Selected Topics won the JOHN C. NIEDERMAIR Award for the best paper presented at the 13th ASE Symposium. His memberships in professional societies include ASNE ASE SNAME ASME and U.S. Naval Institute. He has served as an elected officer in ASE since 1978.

This paper describes naval ship general arrangement design and analysis, a system engineering process that seeks the optimization of the ship as a total system. Through this system engineering process, the ship is geometrically defined by allocating scarce resources of area/volume and functional location. The general arrangement design team synthesizes a design from subsystem requirements, system constraints, and policy-maker influences through iteration and negotiation into the optimum general arrangement. The use of volumetric and area ratios and indices in this process are highlighted. The paper concludes with a discussion of a new methodology now under development for analyzing and comparing general arrangement alternatives. This new general arrangement evaluation methodology links operational performance objectives to ship design philosophy and subsystem effectiveness.
