THE ARCTIC SURFACE EFFECT VEHICLE program

Naval Engineers Journal 1976年第2期88卷 70-83页

作者： KORDENBROCK, JAMES U. HARRY, CHARLES W. Mr. James U. Kor'denbrock:graduated from the University of Cincinnati in 1942 with a BS degree in Aeronautical Engineering. Prior to his current employment his career was in private industry in the aerospace and the aircushion vehicle fields. With industry he was the Technical Director of the SKMR-1 Test Program and was later involved in the Army and Navy SK-5 Programs as well as the SES 100B test craft. With the Systems Development Department of DWTNSRDC he was the Technical Manager of the ARPA Arctic SEV Program but now he is in the Advanced Concepts Office. In addition to ASNE he is a member of SNAME and AIAA and is a registered professional engineer in the State of Ohio. Mr. Charles W. Harry:graduated from the University of Virginia in 1957 with an aeronautical option to his Mechanical Engineers degree. He has since been an employee of the David W. Taylor Naval Ship Research and Development Center (DWTNSRDC). Following wind-tunnel research on several V/STOL aircraft he participated in aerodynamic research on surface effect phenomena for both aircushion and wing-in-ground-effect vehicles. He served as Project Engineer and Test Pilot for the XR-3 one of the first U.S. aircushion vehicles with non-flexible sidehulls. He participated in establishing and managing the research and development of the aero-hydro technology for the then Joint Surface Effect Ship Program Office. More recently he was the Manager Technology Development for the Arctic SEV Program and is presently a member of the Advanced Concepts Office of the System Development Department at the DWTNSRDC.

The potential of the Surface Effect Vehicle (SEV) for operating in the Arctic was investigated. Investigation and development of the technology, for vehicle systems was undertaken as well as definition of the unusual and severe environmental conditions encountered. Photographic and laser data were taken and summarized to establish the surface characteristics of the sea ice in the Arctic Ocean as well as topographic features of coastal and land areas. First‐hand experience was gained in the Arctic during a six‐month test program with an SK‐S SEV at Barrow, Alaska. Designs for SEV's up to 1,000‐tons gross weight with speed capabilities up to 120 knots were prepared. Numerous skirt designs were tested over simulated terrain to establish feasibility of skirts higher than those currently in use. The prediction of the dynamic response of SEV's operating at high speeds over ice and other rough terrain required analytical programs different from those used for operations over water. The detection of ice ridges and estimation of their height is required for high speed operation, and a system utilizing a 95GHz radar was designed and tested. Specific designs of 150‐ton and 500‐ton vehicles were developed to establish their feasibility for conducting long‐range Arctic missions. © 1976 American Society of Naval Engineers

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.

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

The clustered traveling salesman problem

引用

Computers and Operations Research 1975年第2期2卷 115-119页

作者： Chisman, James A. Systems Engineering Program Clemson University United States

The traveling salesman problem is expanded to include the situation where a group of cities (cluster) must be visited contiguously in an optimal, unspecified order. Given several sets of clusters within the problem, a method is developed for optimizing simultaneously the ordering of cities within each cluster and the ordering of clusters. A real-world warehousing problem is shown to fit this formulation. © 1975.

An empirical heuristic learning identification algorithm of Ivakhnenko was modified and used to model an environmental system producing high nitrate levels in agricultural drain water in the Corn Belt. The method amounts to fitting a polynomial to a multi-input single-output response surface. The modifications result in a reduced number of terms in final model equations, a decrease in computational difficulties, and other improvements in the algorithm. This method appears to be advantageous with systems characterized by complexity with many variables and parameters, ill-defined mathematical structures, and limited data. In other words, this algorithm is useful for empirically generating hypotheses about systems of which relatively little is known. © 1975 IEEE. All rights reserved.

The usefulness of software monitors in testing large ‘programs is discussed. Several types of testing strategies based on the use of monitors are surveyed. Since there is a computational overhead involved in employing monitors, attempts are made to minimize the number of monitors employed. This optimization problem is formulated and analyzed in graph-theoretic terms. Implementation aspects are considered through both discussion and examples.

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.

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

Minimization of combined sewer overflows by large-scale mathematical programming

引用

Computers and Operations Research 1974年第3-4期1卷 421-435页

作者： Labadie, John W. Grigg, Neil S. Trotta, Paul D. Water Resource Systems Program Department of Civil Engineering Colorado State University Fort Collins ColoradoU.S.A.

There is a critical need for the development and implementation of control strategies for minimizing receiving water pollution caused by overflows from urban combined sewer systems. Automation and control of such systems has risen as a viable approach to this problem. Control is carried out through regulation of ambient and/or auxiliary storage in the system. The goal is to detain storm flows in the system long enough to prevent flows of a magnitude that exceeds treatment plant capacity, thereby reducing overflow into receiving waters. The problem is first attacked by dividing the large combined sewer system into several mildly interconnected subsystems for which control logic can be developed from application of mathematical programming algorithms consistent with the special characteristics of each subsystem. A flow-projection technique is developed for subsystems not amenable to direct solution by standard optimization techniques. © 1974.

The Navy Standard Hardware program

引用

Naval Engineers Journal 1974年第5期86卷 79-91页

作者： MERZ, JOHN A. The author graduated from the University of Notre Dame in 1955 at which time he received his BS degree in Electrical Engineering. He is presently the Program Manager for Microcircuit Developments and Advanced Modular Concepts at the Naval Electronic Systems Command where previously he had been the Program Manager for the Standard Hardware Program responsible for the overall financial administrative and technical management of the program. He is a member of the Institute of Electrical and Electronic Engineers and a registered Professional Engineer in the District of Columbia.

The Standard Hardware program represents the start of an endeavor to standardize the modular building blocks of all Navy solid state electronic systems. When fully expanded, this vital program will lower the cost and increase the availability of electronic systems for the operating forces. The administrative, electrical and mechanical principles of the program are explained. It is shown that forecasting and controlling system costs can be simplified because: 1) the characteristics of the standard modules are known quantities;2) the designs have been tested;3) Vendors have been qualified, and 4) production costs are known and stable. The impact on maintenance and training is discussed as a function of using modules that are inexpensive enough so that they can be economically discarded upon failure. Statistics derived from Fleet operations are shown to illustrate much better than average reliability for the standard modules. © 1974 American Society of Naval Engineers
