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.

Synthetic fuels are assessed with respect to their potential use aboard Navy ships. The status of petroleum resources and the development of fuels from shale, coal, and biomass is summarized. A scenario of the projected availability of these fuels is presented which shows the sensitivity to funding and schedule. Diesel engine and gas turbine combustor tests with small quantities of coal derived and shale derived fuels are described and these tests results are evaluated for shipboard applications. Special shipboard modifications are discussed such as the replacement of rubber base seals, gaskets, and hoses with viton and teflon, and the use of stainless steel piping because of the fuel characteristics. Considerations for dual fuel systems using Diesel Fuel Marine for starting, stopping, and maneuvering are included based upon early test results. Consideration is given to the use of these fuels in the shipboard environment since they require special handling and adoption of personnel safety measures.

THE UNITED STATES NAVY'S “DESIGN WORK STUDY” APPROACH TO THE DEVELOPMENT OF SHIPBOARD CONTROL systems

引用

Naval Engineers Journal 1976年第6期88卷 62-74页

作者： PLATO, ARTIS I. GAMBREL, WILLIAM DAVID Artis I. Plato:is Head of the Design Work Study/ Shipboard Manning/Human Factors Engineering Section Systems Engineering and Analysis Branch Naval Ship Engineering Center (NAVSEC). He graduated from the City College of New York in 1956 receiving his Bachelor of Mechanical Engineering degree. Following this he started work at the New York Naval Shipyard in the Internal Combustion Engine and Cargo Elevator Section. During 1957 and 1958 he was called up for active duty with the U.S. Army Corps of Engineers and served in Europe with a Construction Engineer Battalion. After release from active duty he returned to the shipyard where he remained until 1961 when he transferred to the Naval Supply Research and Development Facility Bayonne New Jersey. Initially he was in charge of an Engineering Support Test Group and the drafting services for the whole Facility. Later he became a Project Engineer in the Food Services Facilities Branch with duties that included planning and designing new afloat and ashore messing facilities for the Navy. In 1966 he transferred to NAVSEC as a Project Engineer in the Design Work Study Section and in this capacity worked on selected projects and manning problems for new construction and also developed a computer program (Manpower Determination Model) that makes accurate crew predictions for feasibility studies. In 1969 he became Head of the Section. He has been active in the U.S. Army Reserve since his release from active duty and his duties have included command of an Engineer Company various Staff positions and his present assignment as Operations Officer for a Civil Affairs Group. He has completed the U. S. A rmy Corps of Engineers Career Course and the Civil Affairs Career Course and is presently enrolled in the U.S. Army Command and General Staff College non-resident course. Additionally he completed graduate studies at American University Washington D.C in 1972 receiving his MSTM degree in Technology of Management and is a member of ASE ASME CAA U. S. Naval Instit

The purpose of this paper is to discuss a system analysis technique called “Design Work Study”, that is used by the U.S. Navy for the development of improved ship control systems. The Design Work Study approach is one which brings about the most efficient and cost effective man‐machine combination for the ship control functions. Adherence to this process insures that the advantages of automation are balanced against incurred operational and maintenance expense. At present, U.S. Navy doctrine requires that certain ship operating stations, such as steering and propulsion control, be manned at specified ship conditions of readiness. Therefore, if personnel are needed to fulfill these combat environment obligations, excessive automation may only result in unnecessary additional acquisition costs and increased personnel skill requirements. The Design Work Study process can be applied to establish the required fine balance between the degree of built‐in automation and the shipboard manpower levels. In order to explain the techniques that are used for this process, the Authors will present a brief summary of the Design Work Study approach for optimizing shipboard control systems, including an explanation of the formal procedural tools that are applicable. In addition, a practical case study of ship control system design for one of the latest classes of Navy destroyers will be presented. This example will illustrate the resultant savings and benefits that can be realized by a judicious application of this technique. © 1976 American Society of Naval Engineers

Naval Engineers Journal 1975年第6期87卷 79-96页

作者： FAIRBANKS, JOHN W. The author is a graduate of the Maine Maritime Academy Stanford University and the University of Santa Clara. His undergraduate degrees were in Marine and Mechanical Engineering and his Masters Degree Specialization was in Heat-Mass-Momentum Transfer within the Mechanical Engineering Department He has taught Gas Dynamics Thermodynamics and Direct Energy Conversion at Texas A&M and the University of Maryland and has sailed as a licensed Marine Engineer for two and a half years with the American Export Lines currently holding active First Assistant Steam Unlimited and Third Assistant Diesel Unlimited licenses. From 1954 to 1957 he was on active duty in the U.S. Navy serving in the USS Montrose (APA-212) as both Main Propulsion Assistant and Chief Engineer. While employed at Hiller Aircraft Company he was in the Advanced Research Group and worked on the Detached Coanda Effect for VTOL and ground effect machines as well as designing high-speed bearings and high-speed shaft test stands for the SC-142A an experimental tilt wing aircraft program. In 1963 he went to Philco-Ford to design a Brayton Cycle Power System for a solar probe spacecraft and also worked on the Thermal and Power System Design of the IDCSP (DOD's Communication Satellite). At NASA's Goddard Space Center for six years his responsibilities included design fabrication integration test launch and flight operation of solar arrays on two spacecraft and also as Power Systems Engineer for the Orbiting Astronomical Observatory the largest unmanned spacecraft flown. In 1971 he joined NAVSEC where he is currently the Program Engineer on the FT9 Gas Turbine Development Program and Coordinator of the Navy's Materials Programs for advanced gas turbines. Having organized the first two Navy Gas Turbine Materials Conferences he is presently organizing U.S. participation in a joint U.S. Navy Royal Navy Gas Turbine Materials Conference to be held in ‘the United Kingdom in September 1976. Mr. Fairbanks has authored or coauthored 21 technical papers and i

The current Navy philosophy for marine gas turbine engine development is to marinize an existing aircraft turbo jet engine. The FT9 Marine Gas Turbine Engine is a 33,000 horsepower version of the Pratt and Whitney JT9D engine, which powers the 747 aircraft. Marinization of the JT9D basically involves removal of the fan section, addition of a power turbine, structural modification to several components, and material changes to provide corrosion‐resistance in the marine environment. Characteristics and ratings of the individual engine components are discussed as well as the assembled engine. The FT9 design incorporates the modular replacement concept. Modular replacement permits replacement of short‐life components such as the hot‐section without removing the engine from its mounts. The FT9 specification requires development of a condition monitoring system as an integral part of the engine development. Thus, provisions for sensor installations are incorporated in the design. Accelerometers are installed on the internal engine bearing housings to provide improved vibration signals. These accelerometers are mounted on rods such that they are removable without engine disassembly. Extensive borescope provisions are included to provide capability to inspect all hot‐section components without disassembling the engine. The engine life‐limiting component is the hot‐section because of the susceptibility of the blade and vane materials to sulphidation/oxidation at the temperatures encountered with the advanced engines. Sophisticated Made and vane cooling is used to allow high turbine inlet temperatures while keeping blade metal temperatures in a region where sulphidation/oxidation is only moderately active. Coatings are added to blades and vanes to extend engine life. Three FT9 engines will be delivered to the Navy. The target date for provisional Service Approval of FT9 is mid‐1978. FT9 will provide the U.S. Navy with the most advanced marine gas turbine with the highest powe

Newcomb received his undergraduate education at Webb Institute of Naval Architecture graduating in 1966 and is currently completing requirements for a Master of Business Administration degree at the George Washington University. After gradwlting from Webb he was employed by Texaco Inc. Marine Department and later served three years active duty in the Navy as the DEG-7 Project Oficer at Supervisor of Shipbuilding Conversion and Repair Third Naval District. Subsequent thereto he was employed by the Naval Ship Research and Development Center prior to assuming his present position in the Ship System Design Division of the Naval Ship Engineering Center. He is a member of ASNE and SNAME. Mr. Anthony R. Di'hapani received his BS degree in Mechanical Engineering from the University of Wisconsin in 1958 and subsequently completed course requirements for a Master of Engineering Science while an evening student at the George Washington University. He began his engineering career in 1958 in the BuShips Steam Turbine and Gear Branch specializing in steam turbine systems for nuclear submarines. In 1962 after completing a Navy-sponsored Electronics Training Program he joined the SQS-26 Sonar Project and served as Head of the Special Projects Section and subsequently the Test and Analysis Section until selected in 1967 to head the ASW Branch for the newly-churtered DXIDXG Project now the DO963 Ship Acquisition Project in the Naval Ship System Command. In 1970 he was designated a8 Acting Director of the DD963 Technical Management Plans Division and when the PF Program emerged in 1971 was reassigned as Deputy Project Manager for the Patrol Frigate Project.

Late in 1970, Admiral E. R. Zumwdt, Chid of Naval Operations, directed that study begin towards development of a new class of ocean escort to be known BS Patrol Frigate (PF) to take over some of the duties of the Navy's World War II destroyers as these 25 year old ships are retired from the active Fleet. At the same time, the Department of Defense, was significantly revising its basic policies for the development and acquisition of major weapons systems, and PF became the Nay's first major ship claw acquisition under these new policies. This new requirement, as atmound in DOD Directive 5000.1, along with the program constraints imposed by the CNO, required the development of a philosophy and approach towards design, test and evaluation and acquisition which was significantly Merent from ship procurements of the recent past. This paper disc the overall acquisition proms for the Patrol Frigate Class BS it is being developed and implemented to meet these needs and constraints, and provides a commepfary regarding the effectiveness of the appraach as of January 1973. © 1973 by the American Society of Naval Engineers
