His responsibilities included supervision of design production and contract administration. Capt. Jackson was third from the top in managaement of a major shipyard and responsible for design material procurement work order and financial control of two major surface ship prototypes as well a

Anticipated technological advances in the quieting of potential adversary submarines mandate the use of increasingly effective detection systems for U.S. ASW forces. Based on the assumptions that sonar will continue to be the primary means of detection and that the effectiveness of each individual sonar element will not change markedly, one must increase the projected area of the sonar array to improve its capability. The primary SSN mission of anti-submarine warfare will hence require increasing the hull area devoted to the primary sonar detection system. A revolutionary hull form is proposed that maximizes the area available for this purpose. The advantages and disadvantages of this hull form are discussed and feasibility study level design parameters and arrangements presented.

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.

A rationalization of stress-strain behavior of two-ductile phase alloys

引用

Metallurgical Transactions A 1986年第12期17卷 2209-2226页

作者： Ankem, S. Margolin, H. Engineering Materials Program Department of Chemical and Nuclear Engineering University of Maryland College Park Department of Metallurgy and Materials Science Polytechnic University Brooklyn

An extensive literature review indicated that the law of mixture rule can at times account for stress-strain behavior of two-ductile phase alloys in terms of the stress-strain behavior of component phases. In the present investigation, various factors which can contribute to the stress-strain behavior of two-ductile phase alloys are considered, using Ti-Mn alloys as the model system. Particular attention is focused on the effect of elastic, elasto-plastic, and plastic interactions between the phases on the stress-strain behavior. It is shown that the law of mixture cannot adequately explain the stress-strain behavior. The following equation is proposed to describe the stress-strain behavior of two-ductile phase alloys: Pα-β = fαPα c + fβPβ c + Iα-β p, where Pα-β is a given stress-strain property, fα and f/gb are respective volume fractions of α and β-phases, Pα c and Pβ c are corrected properties of α and β-phases, and Iα-β p is the interaction term. It is found that for α- β Ti-Mn alloys, for 0.2 pct yield strength, Iα-β p is positive, negative, or zero depending on the microstructure; but Iα-β p is always positive for the ultimate tensile strength and strain hardening rates and its magnitude depended on the microstructure. The reasons for the nature or sign of the interaction parameter for a given property are discussed in detail.

There is a great deal of emphasis currently in the Navy on the issues of reliability and maintainability. If a system or component is out of commission, it obviously cannot perform its mission. Thus, systems and components must be reliable, with low failure rates, and maintainable, with short repair times when the system does become inoperable. To be effective, these attributes must be incorporated into new ship systems early in the design stage. The Rankine cycle energy recovery (RACER) system is a heat recovery steam cycle designed to recover energy from the exhaust of an LM2500 gas turbine for augmentation of a ship's propulsion system. The RACER system provides several advantages to a gas turbine powered ship, one of which is improved fuel efficiency for significant annual fuel savings. This saving does not come free, however, since, in general, any additional system installed in the ship will have some maintenance requirements. In keeping with the Navy's current emphasis, a key philosophy in the design of the RACER system has been to minimize this maintenance burden. After a brief description of the RACER system and its design philosophy, the techniques being used during the design phase to minimize the maintenance burden on the fleet are presented. Trade-off studies concerning acquisition versus life-cycle costs, including fuel and maintenance costs, are discussed. Innovations incorporated into this state-of-the-art system are reviewed with an emphasis on design for affordability.

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.

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.
