NAVAL ENGINEERs JOURNAL 1982年第2期94卷 286-295页

作者： FAIRBANKs, JW KENYON, CW Capt. John W. Fairbanks USNR:received his M.S. degree from the University of Santa Clara and his B.S. degrees from Stanford University and the Maine Maritime Academy. He taught at the Texas A&M University and the University of Maryland and from 1954 until 1957 served in the U.S. Navy in the Pacific. Subsequently he was a Research Engineer with Hiller Aircraft where he worked on the annular ejector and designed the High-Speed Bearing and Shaft Test Stand for XC-142A and later at Philco Ford worked on advanced space power systems. At NASA-Goddard in 1967 as a Power System Engineer he was employed on several space craft including the Orbiting Astronomical Observatory. From 1971 until 1977 he was employed by the Naval Ship Engineering Center (NAVSEC) as a Program Engineer for FT9 Marine Gas Turbine Development and the Ceramic Demonstrator Gas Turbine and also as Coordinator of Gas Turbine Material Development. In addition he organized the first two Gas Turbine Materials on Marine Environment Conferences and the U.S. participation in the U.S. Navy/Royal Navy Conference. Currently he is a Program Manager in Applied Heat Engine High Temperature Materials and Instrumentation at the Department of Energy (DOE) where he also served as Chairman Engineering Materials Coordinating Committee for DOE. A Naval Reserve Captain and Chairman of the ASME Washington Chapter he also is the former President of the Washington Chapter of the Maine Maritime Academy Alumni former Vice-President of the Stephen Decatur Chapter Naval Reserve Association and the outstanding 1975 Maine Maritime Academy Alumni. Capt. Fairbanks has authored over forty-five technical papers and in both 1974 and 1975 was the winner of the ASE Niedermair Award. Mr. Clarence W. Kenyon:graduated from the State University of New York Maritime College in 1960 and sailed on a Third Assistant Engineer's license with Isbrandtsen Steamship Company before accepting an engineering position with the Long Beach Naval Shipyard in 1961. In addition to his responsibilit

synthetic fuels are assessed with respect to their potential use aboard Navy ships. The status of petroleum resources and the development of fuels from.s.ale, coal, and biom.s. 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.

THERmO-LUmINEsCENCE OF KBR-TL AROUND ROOm-TEmPERATURE

引用

JAPANEsE JOURNAL OF applied physics 1981年第6期20卷 1069-1072页

作者： JOsHI, RV CHAUDHARI, RT Applied Physics Department Faculty of Technology and Engineering M.S. University of Baroda

Thermal glow curves of KBr: Tl phosphors were investigated after irradiation with ultraviolet light or X-rays at room temperature. It was found that the specimens exhibited a single glow peak in the temperature range of 340–370 K, the position of the maximum of which depended on the history of the sample. Present work included the effects on the thermoluminescent characteristics of the phosphor when subjected to various thermal and/or mechanical treatments. It is proposed that the Tl+ ion-anion vacancy pair situated in the perfect region of the lattice is responsible for the peak at 370 K. shift in the peak position to lower temperature side is attributed to the Tl+ ion-anion vacancy pair in the distorted region of the lattice, the distortion being caused by the vacancy cluster in the neighbourhood of the pair.

NAVAL ENGINEERs JOURNAL 1981年第2期93卷 154-161页

作者： KROLICK, CF THE AUTHOR:: received his B.S. degree in Physics from Saint Francis College in 1962 and subsequently his M.S. and Ph.D. degrees in Nuclear Engineering from the University of Maryland in 1969 and 1971. He is the Director of the Navy's Shipboard Energy R&D Program at the David W. Taylor Naval Ship Research and Development Center and has received awards for Outstanding Performance and Sustained Superior Performance. While at the University of Maryland he was recipient of an NSF Fellowship an NDEA Fellowship and an AEC Traineeship. Dr. Krolick is a member of Sigma Xi and the American Nuclear Society.

The U.s. Navy shipboard energy situation is presented both in terms of historical, current, and projected postures. R&D programs to minimize the impact of diminishing fossil fuel resources while ensuring full operational readiness are described. Near term efforts are directed at the achievement of the 1985 Chief of Naval Operations goal of twenty percent reduction in fossil fuel consumption per underway steaming hour, and they are intended primarily for the conventional steam-powered Fleet which presently comprises eighty-four percent on an installed horsepower basis. Longer range efforts attempt to facilitate the goal of a more energy-efficient future Fleet in terms of new construction ships. Alternate Fuels programs are structured to provide a capability to operate on future fuels which are readily available, and they include development of guidelines for the use of a broad range of petroleum-base fuels as well as the qualification of snythetic fuels derived from coal, oil shale, and tar sands.

Traditional ship acquisition practices no longer support the requirements of today's shipbuilding programs. These practices require development of major combat and ship systems to be essentially complete prior to issuance by the government of the Request For Proposal (RFP) for ship detail design and construction. With the need for timely delivery of warships equipped with the m.s. modern weapon systems possible, and maximum remaining years of functional effectiveness after delivery becoming increasingly important, new acquisition strategies are essential. “Design Budgeting,” an innovative new Navy acquisition and design strategy, is now a proven concept. Developed and implemented by the AEGIs shipbuilding Project, it has been explored in depth with the shipbuilding Industry as an alternative acquisition process that enables Combat system development and ship acquisition to proceed concurrently. applied for the first time in the acquisition of Ticonderoga (CG-47), its use permitted development of major portions of the AEGIs Combat system (later to be Government Furnished Equipment to the shipbuilder) to continue well into ship detail design and construction without impact on overall schedules. Hundreds of changes to the ship engineering baseline which resulted from continued development and test of Combat system, were incorporated into the shipbuilding contract with no cost increase or delay and disruption of the shipbuilding schedule. Proven, adaptable, and available now, “Design Budgeting” is an acquisition and design strategy than can satisfy the requirements of current and future shipbuilding programs.

It is shown that “at-sea” measurements of the transverse waves generated by a deep-draught ship can be used to determine the course and speed of the ship and its distance from the point of measurement. Three staff gauges in a close proximity are required along with telemetering equipment and a spectral analyzer. By continuously monitoring the wave spectra at three points, the transverse waves in the ship's wake are detected as spikes in each of the spectra. A narrow band about the transverse wave period can then be monitored to obtain the necessary information.

INVEsTIGATION OF ULTRAsONIC VELOCITY AND RELATED PARAmETERs IN LIQUID-CRYsTALLINE mIXTUREs

引用

mOLECULAR CRYsTALs AND LIQUID CRYsTALs 1980年第4期60卷 297-310页

作者： GEORGE, AK VORA, RA PADmINI, ARKL Applied Physics Department Faculty of Technology and Engineering M.S. University of Baroda Baroda 390 001 India. Applied Chemistry Department Faculty of Technology and Engineering M.S. University of Baroda Baroda 390 001 India.

Investigations of ultrasonic velocity, specific volume and related parameters were carried out in a mixture ofp-n-butoxybenzylidene-p-chloroaniline (BBCA) andp-anisal-p-toluidine (pApT) at eight different concentrations. BBCA exhibits polymorphism with two smectic phases, viz., smectic B and smectic A, whilepApT is non-m.s.morphic. All the mixtures studied were nematic, the m.s.morphism vanishes below 34.3 mole percent of BBCA. specific volume showed a large increase in the vicinity of the phase transition and the ultrasonic velocity showed an abrupt minimum near the transition. The adiabatic compressibility showed a maximum near the phase transition. It was found that the dip in ultrasonic velocity, change in specific volume and the jump in adiabatic compressibility at the transition decreases with increasing concentration of the non-m.s.morphic compound. The parameter, viz., molar sound velocity was also estimated. The coefficient of thermal expansion and adiabatic compressibility were also estimated and they were found to attain very high values near the phase transition. The experimental results are explained on the basis of de Gennes theory of pre-transitional effects generalized by Bendler. The critical exponents are estimated in the isotropic as well as in the nematic phases.

NAVAL ENGINEERs JOURNAL 1979年第5期91卷 65-73页

作者： BOLD, NT BOURETTE, AP Dr. Norbert T. Bold graduated from Marquette University and later received his M.S. and Ph.D. degrees in Electrical Engineering from Northwestern University. He served three years as a Naval Engineering Officer aboard an Aircraft Carrier and a Minesweeper and has nineteen years technical experience in shipboard navigation underwater target and SDMS projects for the Navy. He is currently a Program Manager in the Autonetics Marine Systems Division Rockwell International where his primary assignment is the development of advanced concepts and applications of SDMS to Navy programs. He has published several technical papers. was elected to four Scholastic Honorary Societies and was the recipient of a NROTC Scholarship. Mr. A.P. Bourette Manager Systems Applications Autonetics Marine Systems Division. received his B.S. degree in Mathematical Physics from Long Beach State University. He began his career with a Computer Analysis Unit. performing tasks related to computer application. programming and interfacing. He has made significant contributions to the Central Computer Complex approach adopted for the SSN-688 Combat System and has performed inertial systems engineering efforts on the MK2 SINS for the POSEIDON Program. He spent some time in the Washington D.C. area providing technical expertise to various Navy organizations. Upon his return he soon was selected to manage the Systems Applications organization at Rockwell International. This organization is primarily responsible for the Shipboard Application of SDMS. He has directed several application studies showing the significant advantages associated with multiplexing. Recently. he provided the technical direction for the FY80 SSN SDMS Preliminary Design Phase.

Rockwell International is currently under Navy contract to fabricate the Engineering Development model (EDm) of the shipboard Data multiplex system (sDms) for general data transfer aboard surface ships and submarines. The application of sDms significantly reduces hardware such as cables, switchboards, and signal Data Converters (sDC), and it provides the capability to add many desired features which are currently not practicable. In applying sDms to a specific ship, a m.s.ive amount of signal data m.s. be considered. The Application Design Automation program (ADAP) is a set of computer programs that have been developed to accomplish this task. ADAP com bines signal population data, ships configuration data, and sDms hardware characteristics to produce an sDms configuration layout together with documentation necessary to analyze, evaluate, and implement the system. specific outputs include hardware requirements, system layout, and interface requirements including wire list information. The Timing, Event and Load simulation (TELs) program simulates sDms and provides performance data (system capacity, throughput rate, transport delays) for any system configuration. Conventional sDCs can be elimianted from Navy shipboard systems when sDms is used. sDms provides the necessary data distribution, signal conversion, and computer interface. In addition, many functions of the conventional switchboards can be performed within sDms, thus reducing the size or eliminating conventional switchboards. Very small switch-bomb will provide the necessary control of data distribution. With sDms, an automatic and continuous Noise and Vibration monitoring (NVm) capability is readily available. The automated NVm function will enhance the safety, operation, and maintenance of the ship. Problems with machinery or excessive self-noise generation will be detected much sooner, and corrective action implemented on a timely basis.

Journal of the American society for Naval Engineers 1957年第2期69卷 369-374页

作者： HARRIsON, CHARLEs W. COMMANDER CHARLES W. HARRISON JR. USN attended the U. S. Naval Academy Preparatory School the U. S. Coast Guard Academy and the University of Virginia where in 1939 he received the S.B. degree in Engineering and in 1940 the degree of Electrical Engineer. In 1942 he was graduated with the S.M. degree in Communication Engineering from Cruft Laboratory Harvard University and that summer completed the Navy Course in Radar Engineering at Massachusetts Institute of Technology. Subsequently for several years he was engaged in lecturing to officers of the Armed Forces assigned to the radar schools at Harvard and Princeton Universities. He has had four tours of duty in the Electronics Design and Development Division Bureau of Ships two at the U.S. Naval Research Laboratory one at the Signal Corps Engineering Laboratories (Evans Signal Laboratory) and one at the Philadelphia Naval Shipyard. His experience includes amateur naval and broadcasting operation. In 1951 Commander Harrison was selected for training in Advanced Science at Harvard University under sponsorship of the Office of Naval Research. This program led to the M. Eng. degree in 1952 and Ph.D. degree in Applied Physics in 1954. Commander Harrison is presently Electronics Officer on the Staff of Commander Operational Development Force. He is a member of several societies and associations including the Harvard Chapter of the Society of Sigma Xi.

summary: The measurement of the magnetic field associated with a linearly or elliptically polarized electric field, using a small loop, or magnetic probe, is discussed. It is shown that in general a loop will not measure the magnetic field faithfully because the sensing element responds to the antenna modes as well as the transm.s.ion line mode excited in the loop structure by the incident electromagnetic field. A special shielded loop with two gaps was invented to eliminate or reduce the effect of the antenna modes. It is anticipated that this device will be found useful in the field of direction finding. © 1957 by the American society of Naval Engineers, Inc.
