作者： HOPE, JP STORTZ, VE Jan Paul Hope a native of Northern Virginia received his bachelor of science degree in mechanical engineering from the University of Virginia in 1969. Upon graduation he began his career in the Department of the Navy with the Naval Ship Systems Command in the acquisition of patrol craft mine sweepers and submarine rescue ships. In January 1971 he transferred to the ship arrangements branch of the Naval Ship Engineering Center. 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 the Naval Ship Engineering Center Mr. Hope was general arrangement task leader on the AO-177 CG-47 CSGN CSGN (VSTOL) CGN-9 (Aegis) and CGN-42 and he also assisted in the landmark Naval Sea Systems Command civilian professional community study. In 1978 he was selected as acting head of the damage control section and subsequently 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. Mr. Hope was selected for the first class of the NA VSEA commander's development program. While on the program he served in the DDGX combat systems engineering division and the DDGX project office of NA VSEA was the assistant director for ship design in the office of the Assistant Secretary of the Navy for shipbuilding and logistics and was the director of weight engineering and the director of systems engineering for the DDG-51 project in NA VSEA. Upon completion of the program Mr. Hope was assigned as the deputy director of the boiler engineering division to create a new division as a major fleet support initiative by NA VSEA. In June 1985 he joined the staff of the Assistant Secretary of the Navy for shipbuilding and logistics. Mr. Hope was presented the Department of the Navy meritorious civilian service medal in June 1983 for his service with the Office of the Assistant Secretary of the

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.

An expert system is described which allows real-time analysis of the noise and vibration signature of vibrating machinery. The system presented consists of an adaptive algorithm which varies the band width of analysis channels as a function of a signal complexity factor and a measure of the rapidity of local signal change. Overall program architecture is presented as well as detailed discussion of signature functional identification and statistical trend modules which are adaptable to a wide variety of input data base configurations. Execution of the program on a “super-mini” in FORTRAN code with direct graphics output and on 68000 series based firmware using ADA is discussed. Results are presented of program execution on Navy hydrophone and propulsion gas turbine data showing current signature and projections of trend to future times compared with failed condition signatures. Correlation results for such predictions are also discussed.

AbstractThew‐centroid problem, denoted by (C), is an optimization problem which has been shown by Kariv and Hakimi to be equivalent, on a tree graph, to the 1‐median location problem, denoted by (M). For a general (weighted) connected graphGwe develop a duality between (C) (which is defined onG) and a block optimization problem, denoted by (B), and defined over the blocks ofG. A block is a maximal nonseparable subgraph. We analyze (B) and (C) by means of two problems equivalent to (B) and (C) respectively, but defined on a blocking graphGwhich is always a tree. We give an O(∣V∣) algorithm to solve the two problems onG, and we characterize the solutions. We also show that the solution to a 1‐median problem defined onGeither solves (M) on the original graph G or localizes the search for a solution to (M) to the vertices of a single block. We introduce an extended version of Goldman's algorithm which (in linear time) either solves (M) onG, or finds the single block ofGwhich contains all solutio

MASTER ORDNANCE REPAIR

引用

NAVAL ENGINEERS JOURNAL 1985年第3期97卷 47-53页

作者： CHENARD, JH USN Captain John H. Chenard:is a 1960 U.S. Naval Academy graduate and received his M.S. degree in aerospace physics in 1968. He served on seven destroyers and cruisers in weapons billets before being designated engineering duty officer in 1977. His engineering duty assignments include Terrier department officer at NSWSES from 1977 to 1980 and Spruance class combat systems engineer at Naval Sea Systems Command until 1982. Capt. Chenard developed the master ordnance repair program with support from Shipbuilders Council of America. He is currently the NAVSEA project manager for long range missile weapon systems. Capt. Chenard has been a member of the American Society of Naval Engineers (ASNE) since 1981.

The overhaul of high technology combat systems presents problems in logistics, management, and testing that increasingly challenge the way that these issues have been resolved in the past. Recognizing that a number of surface ships with complex combat systems will be overhauled by private shipyards, the Naval Sea systems Command (NAVSEA) initiated the master ordnance repair (MOR) program. The objectives are to improve the quality of combat system overhauls in the private sector and to assure that this maturity keeps pace with developing technology. The MOR program is designed to identify, and qualify, those companies and private shipyards technically capable of managing combat system work and of conducting combat system testing. A team of combat system and overhaul experts from government agencies conducts on-site visits of MOR applicant facilities. The team examines aspects of the companies' capabilities, then recommends qualification, or not, to NAVSEA. This paper explains the MOR program and its implementation, discusses qualification of an applicant, identifies support problems unique to the private sector, and proposes a monitor system which will ensure program integrity.

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.

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.
