NAVAL ENGINEERS JOURNAL 1980年第2期92卷 148-155页

作者： SEJD, JJ WATKINSON, KW HILL, WF Mr. James J. Sejd received his B.S. degree in Civil Engineering from Case Western Reserve University and has since undergone considerable graduate study at both The George Washington and American Universities. He served almost four years in the U.S. Navy as a Naval Aviator and enjoys the unique distinction of being qualified in both Heavier- and Lighter-than-Air aircraft. Early in his career he was employed at the Navy's Bureau of Ships in the capacity of a Structural Designer and Structural Research Monitor. In 1966 he joined the Staff of the Center for Naval Analyses where he was involved in the mathematical modeling of ships and aircraft and in economic “trade-off‘ analysis. In 1970. he went to the Naval Ship Engineering Center as an Operations Research Analyst in the Ship Design and Development Division. At the present time he is employed as a Program Manager for the Naval Sea Systems Command Ship Design Research and Development Office. A member of ASNE since 1973 he also is a member of the Association of Scientists and Engineers at NAVSEA the Operations Research Society of America and the Lighter-Than-Air Society. Mr. Kenneth W. Watkinson received both is B.S. and M.S. degrees in Engineering Science from Florida State University in 1970 and 1971 respectively. Since graduation he has been employed at the Naval Coastal Systems Center (NCSC). Panama City. Fla. where he is primarily involved in the investigation of the stability and control of underwater vehicles. For the past four years he has been the Task Leader and Principal Investigator for the NCSC portion of the Advanced Submarine Control Program involved in developing control design methods and the instrumentation system for the Submarine Control System Test Vehicle. Mr. William F. Hill is currently the ASCOP Program Manager at Lockheed Missiles & Space Company (LMSC) Inc. where he has the overall responsibility for design and construction of the Control System Test Vehicle (CSTV). He entered the aircraft industry in England as an Apprentice w

As part of the Advanced Submarine Control program (ASCOP), the Naval Sea systems Command has developed an open water Submarine Control system Test Vehicle (CSTV). This vehicle is a 1/12 scale model of an SSN 688 Class Submarine, with provisions for easy geometric changes. Such changes include alternate Sail size and location, the addition of parallel middle-bodies, alternative tail sections, and alternative control configurations. A self-contained instrumentation and control system provides the capability for “on-board” recording of all relevant Submarine-state variables, over the entire speed and depth range, to a degree of data accuracy exceeding any known system. With the means thus available to correlate measured vehicle hydrodynamics with selected maneuvers, conditions, and changes in hull geometry and control surface configuration, modern mathematical techniques for improving submarine equations of motion can be employed to permit dramatic design enhancements in both safety and performance. This paper provides the rationale and history of the development of this vehicle, a description of the instrumentation and control package, and a description of the vehicle itself.

Fort Schuyler N. Y. from which he had received his BS degree in Marine Engineering in 1956. After working far various firms as a Marine Engineer he joined John J. McMullen Associates. Inc. (JJMA) as the Supervisor of Marine Engineering. In 1967 he was appointed Manager of Special Projects responsible for Chemical and LNG Transport Projects followed in 1969 by promotion to Vice President—Marine Engineering at which time he directed the company's efforts on the PF Program and the conceptual design of the AEGIS DG. Mr. Basile attained his present position as Executive Vice President. JJMA. in 1974 and in this capacity he now directs the efforts of the Technical Services Division and assists in establishing and implementing corporate management administrative. and fiscal policies. Mr. Norman P. Mashin received his MBA degree in Management for Engineers from Baruch College in 1971 and his BS degree in Nuclear Science from New York State Maritime College. Fort Schuyler. N. Y. in 1964. From 1964 until 1969 he was with Rosenblatt & Son Inc. in their Engineering Division where he went from Marine Engineer to Head of Machinery and Piping Preliminary Design Division and was responsible for all technical aspects of conceptual and preliminary design. Since 1970 he has been with John J. McMullen Associates. Inc. where he is presently Director. Programs Management responsible for the definition of technical requirements and deliverables work assignments and cost control. As Program Manager he directed all efforts for the Reserve Merchant Ship Defense System coordinating all aspects of design and construction effort both at JJMA and with the major subcontractors involved in the contract.

The prototype Reserve Merchant Ship Defense system (RMSDS) Facility will provide a base for naval helicopter operations on board a commercial Containership with minimal time and ship conversion effort. Basically, the design makes use of ISO dimensioned compatible modules to provide for living and operational support facilities for a Navy support detachment. Initially, the design has been developed to suit the LIGHTING Class of Containership and will support four SH—3H type helicopters and a naval detachment of sixty—five officers and men. This facility consist of four major elements, which are: Flight Deck, Accommodation Array, Hangar Array, and JP—5 Fuel system Storage and Service Array. Modular construction will be utilized to the maximum extent possible so as to aid in assembly, disassembly, and transportation of the RMSDS Facility. Interconnections between the various modules are all of the quick disconnect type, in keeping with the modular concept, thereby minimizing the potential for delays in assembly and disassembly. The RMSDS Facility is fully capable of sustaining and supporting SH—3 helicopter operations, including necessary command—and—control, maintenance/logistics support, integral personnel support facilities and provision of its own electric power for all uses within the complex. The services to be supplied by the host Containership are limited to fresh and salt water services as well as emergency electrical power (However, the RMSDS Facility DOES have additional back—up electrical power). Furthermore, to minimize development and fabrication costs of the RMSDS Facility, approved commercial marine equipment was utilized wherever possible. The logistic and tactical advantages, of the RMSDS/Intermodal Transportation system combination are explored and explained. Various alternative naval missions all utilizing various forms of VSTOL aircraft (SH—3, RH—53, CH—S3, AV—8A) are briefly described: Mine Counter Measures, Harbor Defense and Riverine Warfare, Ma

He began his career with the U.S. Navy in 1965 as a Mechanical Engineering Trainee in the Philidelphia Naval Shipyard Design Division under the BUSHIPS Cooperative Education Training Program. In 1911 he joined NAVSEC as a Mechanical Engineer in the Fluid Systems Branch. For the past two years he has primarily been involved in conducting alternative auxiliary heating system “tradeoff” studies and in the design of total energy/waste heat recovery systems for the PF 109 Class Sea Control Ship DG/AEGIS and AO 177 Class. He is a registered Professional Engineer in the District of Columbia a member of ASE ASME and SNAME and a candidate for the Master of Engineering Administration degree at The George Washington University.

Energy used by U.S. Navy ships is viewed in the context of the national situation. Shipboard usage and the controlling variables are summarized. Research and development being planned by the Navy is described. Efforts relate to conservation of energy as well as consideration of new fuels including hydrogen and liquid hydro-carbon fuels derived from coal, oil shale, and tar sands. A brief account is given of work sponsored by the Department of Interior to produce hydrocarbon fuels, and initial Navy efforts to characterize and evaluate one such fuel is reported. This fuel has been burned at sea in the USS Johnston (DD 821). Development of conservation measures encompasses the utilization of waste heat from gas turbine and diesel engine exhausts and diesel water jackets; more efficient machinery; and reduction of energy requirements. Specific developments discussed include a design methodology to optimize waste heat utilization and higher efficiency gas turbine systems.
