The SA'AR-5 Corvette program is the first major warship construction to be entirely accomplished using a 3-dimensional, interference checked computer based design. This paper discusses the organization and approach used to create the design models which form the basis for interference checking as well as the source of extracted production data. The design or product model is the nucleus of the computer data base that defines the configuration of the entire ship. The data base includes geometry, weight, and material, as well as production control data. The ability of the computer to link such diverse information is the key to maintaining configuration control during the course of the design and construction. The ease with which formatted manufacturing data (both N.C. fabrication and installation) can be extracted enables the preparation of detailed packages containing the desired geometry as well as the associated material and sequencing data, thus assuring the producibility of the design. The SA'AR-5 design is CAD/CAM's state of the art in U.S. shipbuilding.

In supporting U.S. polar programs, U.S. Coast Guard icebreakers have two missions: logistics support (break-in and ship escort), and research support (providing research platforms for the U.S. polar research community). The retirement in recent years of CGC Glacier and the last two Wind class icebreakers has left the Coast Guard with just two Polar class icebreakers to conduct missions in the Arctic and Antarctic. It has become clear in recent years that the research community needed enhanced scientific facilities available on board the two remaining Coast Guard icebreakers. Historically, the Coast Guard has provided scientific support to embarked scientific parties on board its icebreakers, carrying researchers in a wide variety of fields into the ice of both polar regions. After conducting a survey of the polar research community and holding a series of meetings with users of the vessels to ascertain the needs of the user community, the Coast Guard has undertaken an effort to upgrade the research support capability of the two existing Polar class vessels. Improved research support capabilities were designed with ongoing consultation with the polar research community. The upgrade of facilities on the two vessels was divided into two phases: Phase I, an upgrade of geological facilities and Phase II, an upgrade of the general oceanographic facilities. This paper focuses on the design work for the Phase II upgrades on CGC Polar Sea, consisting of construction of oceanographic and geological lab spaces, construction of a new oceanographic winch room, the addition of over-the-side weight handling equipment, the addition of topside support services for scientific vans, and the acquisition of new science winches.

This paper highlights the survivability concerns in the design of ship service power systems. The paper gives a brief description of what constitutes a typical ship service electric power system and concentrates on electric power generation and associated controls. Established survivability design principles and guidelines are highlighted and the application of those guidelines are discussed. General Specifications (Gen Specs) for Ships of the U.S. Navy are cited as the cornerstone for design. Specific design criteria are cited as well as the rationale associated with the survivability design guidelines pertaining to power generation and distribution. The application of these survivability design guidelines plus the use of the deactivation diagram/damage tolerance analysis cited in the Gen Spec section 072e will enhance overall design and help ensure survivable electric power systems for surface combatants.

SIMPLIFICATION OF GAS-TURBINE INTAKE ANTI-ICE SYSTEMS

引用

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.

SHIPBOARD STOWAGE OF FLAMMABLE AND COMBUSTIBLE LIQUIDS

引用

NAVAL ENGINEERS JOURNAL 1986年第3期98卷 199-208页

作者： DROPIK, MV graduated from the University of Detroit in 1969 with a bachelor of science degree in mechanical engineering. He began his Navy career that year with the Naval Ship Systems Command PMS-382 Ship Acquisition Manager for Mine Patrol and Yardcraft. In 1971 he transferred to the General Arrangements and Habitability Design Branch of the Naval Ship Engineering Center. From 1971–1972 he attended graduate school at the University of California at Berkeley through the Navy's long-term training program and received his master's degree in industrial engineering. He currently heads the Auxiliary/Amphibious/Minecraft/Special Projects Branch of NAVSEA's Arrangements Design Division. His duties in this capacity include those of program manager of the U.S. Navy's flammable liquids program a position which he has held for the last eight years. His experience encompasses the general arrangements habitability storeroom and office design of aviation auxiliary amphibious mine warfare and high performance ships and craft.

The uncontrolled proliferation of flammables and combustibles aboard ship, in addition to posing an obvious fire and explosive hazard, has seriously degraded the survivability and increased the vulnerability characteristics of U.S. Navy surface ships. This problem for the most part has been superficially attributed to a widespread shortage of flammable and combustible stowage capacity. As a result, current solutions have been limited to increasing stowage capacity through additional storerooms and development of more efficient stowage aids. Unfortunately, these solutions simply address the symptoms, are of a corrective nature, and do not eliminate the fundamental causes of the problem. The paper conducts a more systematic and comprehensive investigation into identifying and resolving the flammable liquids problem by considering it from a ship life cycle perspective. In this way, the problem is shown to be the resultant accumulation of a number of causes which occur during a ship's design, construction, and operational phases, and which collectively manifest themselves as a major shortage of flammable and combustible liquid stowage space aboard current fleet ships. Actions are then formulated to eliminate or counteract these fundamental causes, and validated by application to a hypothetical case study.

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.

TESTING OF A MAGNETICALLY TREATED WEST-GERMAN DIESEL-ENGINE

引用

NAVAL ENGINEERS JOURNAL 1984年第3期96卷 243-251页

作者： WHITE, JW The AuthorLieutenant Commander James W. White USNenlisted in the U.S. Navy in 1964 and served as an electronics technician and as a nuclear power instructor. As a student in the Navy Enlisted Scientific Education Program he received his Bachelor of Science degree in engineering physics at the University of Oklahoma and was commissioned an ensign. As a junior officer he served as engineer in USSMarathan (PG-89) and was the commissioning main propulsion assistant in USSPaul F. Foster (DD-964). Following his tour in that ship he continued his studies at Massachusetts Institute of Technology where he received a Masters of Science in mechanical engineering as well as the professional degree of ocean engineer. After M.I. T. he served at David Taylor Naval Ship Research and Development Center as a project engineer in the Ship's Electric Propulsion Program and at Naval Sea Systems Command as a design and engineering officer.

Aluminum block nonmagnetic diesel engines have been less reliable in service than their cast iron counterparts. Additionally, nonferrous engines are produced in small numbers exclusively for military use and thus have no commerical base with which to enhance logistics support. A West German engine manufacturer, Motoren-und-Turbinen-Union (MTU), has developed a method for magnetically treating cast iron engines in such a way as to reduce their magnetic signatures and thus make them available for mine countermeasures applications. In order to take advantage of the improved reliability and supportabitity of ferrous but magnetically treated production engines, the U.S. Navy conducted an extensive test and evaluation program to confirm or question the suitability of the engine for a new class of mine countermeasure ships. Testing consisted of a 1000-hour endurance run in accordance with military specifications for high speed diesel engines and high impact shock testing. The magnetic signature of the engine was mapped before and after each test in order to verify that neither shock nor extended running could change the magnetic properties of the engine. A maintenance demonstration was also performed in which Navy mechanics carried out various tasks in an effort to identify engine details which could be altered and thus improve the engine's maintainability. Subsequent magnetic testing was intended to show-that part interchanging and routine maintenance would not change the magnetic character of the engine. This paper describes the unique characteristics of the MTU 6V396TB63 diesel engine and will consolidate and illustrate the results of endurance, shock, magnetic, and maintenance testing.
