At 70 miles per hour, overcoming aerodynamic drag represents about 65% of the total energy expenditure for a typical heavy truck vehicle. The goal of this US Department of Energy supported consortium is to establish a clear understanding of the drag producing flow phenomena. This is being accomplished through joint experiments and computations, leading to the 'smart' design of drag reducing devices. This paper will describe our objective and approach, provide an overview of our efforts and accomplishments, and discuss our future direction. © 2004 by the American Institute of Aeronautics and Astronautics, Inc.

The hazards of ionizing radiation in space continue to be a limiting factor in the design of missions, spacecraft, and habitats. Shielding against such hazards is an enabling technology in the human and robotic exploration and development of space. If the design of the radiation shielding is not optimal for the mission, then excess mass will be launched, mission costs will be higher than necessary, and useful payload will be reduced. This reduced mission capability scenario can be repeated for other technical design disciplines. These other disciplines can also effect each other’s requirements. A collaborative engineering environment can optimize ALL design parameters for cost (or another parameter) producing a spacecraft that will meet all mission requirements at the minimum cost. This paper describes two environments that include space radiation analyses and the inclusion within a larger optimization methodology.

NAVAL ENGINEERS JOURNAL 2003年第1期115卷 57-65页

作者： Lively, KA Seman, AJ Kirkpatrick, M KENNETH A. LIVELY graduated from the University of Colorado with a BS in applied mathematics and an MS in mathematics in 1976 and from the Massachusetts Institute of Technology with an MS in electrical engineering and the degree ocean engineer in naval architecture and marine engineering in 1984. He retired from the U.S. Navy in 1989 after 23 years of service. Assignments included electrical officer on the USS Constellation (CV 64) project engineer for the DDG 51 machinery control system (NAVSEA) and DDG 51 Technical Director (NAVSEA). He was vice president of the PDI Division of Bird-Johnson Company from July 1989 to November 1998 where he managed various gas turbine and machinery controls related development projects. He joined Anteon Corporation's Systems Engineering Group as senior controls engineer in December 1998 where he provided technical support to the integrated power systems program (NAVSEA PMS 510) and managed the Office of Naval Research Afloat Laboratory. DR. MARK KIRKPATRICK is currently an independent consultant in human factors and work-load/manning analysis and modeling. He holds a Ph.D. degree in experimental psychology from The Ohio State University and has 34 years of experience in applied human factors. From 1982 through 2000 Dr. Kirkpatrick served as the senior vice president of Carlow International. Prior to joining Carlow in 1982 Dr. Kirkpatrick served as a member of the technical staff at North American Rockwell's Missiles Division and as a project director and vice president for Essex Corporation. His areas of expertise include workload simulation task analysis operator-in-the-loop simulation human performance experimentation statistical analysis and human factors T&E. He has directed and/or participated in human factors projects for the U.S. Navy U.S. Army NASA Department of Transportation the U.S. Nuclear Regulatory Commission and private industry. ANTHONY J.

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central Control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. Advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.

Navy's CFC & Halon elimination program

引用

NAVAL ENGINEERS JOURNAL 2000年第1期112卷 91-112页

作者： Toms, GS Breslin, DA Brunner, GP Thill, JC Gregory S. Toms RE:is the CFC & Halon Elimination Program Manager for the Naval Sea Systems Command (NAVSEA). He received a master of science degree in mechanical engineering from the University of Maryland and a B.S. degree in mechanical engineering from West Virginia University. From 1984 to 1997 he was employed at the Naval Surface Warfare Center Carderock Division Annapolis Detachment (formerly David Taylor Research Center) where he worked on the development of advanced centrifugal compressor air conditioning plants for shipboard applications. He received the Stratospheric Ozone Protection Award in 1998 from the U.S. Environmental Protection Agency in recognition of his exceptional leadership and technical achievements in eliminating ozone-depleting substances from Navy ships. He is licensed as a registered Professional Engineer in the state of Texas. David A. Breslin P.E.:is the Director of Technical Operations for the Naval Surface Warfare Center and is the Chairperson of the ASNE Committee on Environmental Engineering. He received a master of science in aerospace engineering from Virginia Tech in 1991 a master of engineering administration in industrial & systems engineering from Virginia Tech in 1991 and a bachelor of engineering in mechanical engineering from Stevens Institute of Technology in 1985. From 1993 to 1997 he was the program manager of the Naval Sea Systems Command's CFC & Halon Elimination Program. Because of his many efforts he received a Stratospheric Ozone Protection Award in 1995 from the U.S. Environmental Protection Agency in recognition of “exceptional contributions to global environmental protection”. Gregory P. Brunner:was employed by the Carderock Division of the Naval Surface Warfare Center and Naval Sea Systems Command (NAVSEA) from 1983 until 1997. From 1993 to 1997 he served as the R&D program manager for the NAVSEA CFC & Halon Elimination Program Office. Program efforts resulted in the development of new refrigerants for backfit into existing shipboard air-conditioning

The domestic production of the most powerful Ozone-Depleting Substances (ODSs) has permanently ceased and the abundant supplies of a number of inexpensive refrigerants, fire-fighting agents, and solvents, once taken for granted, are now a thing of the past. The Navy's original strategy of conserving ODSs, converting systems and processes where feasible, relying on strategic reserves where necessary, and developing "ozone-friendly" equip ment for new-design surface ships and submarines is succeeding. The purpose of this paper is to document the Navy's efforts to date relative to combating the threat to uninterrupted Fleet operations posed by the cessation of ODS production. Specifically, this paper addresses the Navy's shipboard conversion programs for air-conditioning and refrigeration (AC&R) systems, the development of next-generation AC&R systems, the selection of halon substitutes for new-construction fire-fighting systems, and the Navy's alternative to CFC-113 in the cleaning of critical oxygen systems.
