SHIPBOARD DATA MULTIPLEX SYSTEM - NEW CONCEPT FOR WARSHIP ELECTRONIC SYSTEM INTEGRATION

NAVAL ENGINEERS JOURNAL 1979年第4期91卷 51-61页

作者： WAPNER, M THE AUTHOR graduated from the City College of the City University of New York from which he received both his Bachelor and Masters degrees in Electrical Engineering. He joined the Naval Applied Science Laboratory in 1961 where he served as Project Engineer for Ships Inertial Navigation Systems (SINS) and related equipments. Since 1967 he has been employed by the Naval Sea Systems Command (formerly NAVSHIPS) Research and Technology Directorate. initially as Navigation and Interior Communications Program Manager and currently as Director Combat Support Systems R&D Office. In addition to being the Program Manager for the Shipboard Data Multiplex System. his responsibilities include supervising research and development in areas of surveillance. fire control command and control and related command support functions. He is active in a number of U.S. Navy and foreign government information exchange programs has authored several technical papers and is a member of the Institute of Navigation and the Institute of Electrical and Electronic Engineers.

The Shipboard Data Multiplex System (SDMS) is a general purpose information transfer system directed toward fulfilling the internal data Intercommunication requirements of a variety of naval combatant ships and submarines in the 1980–1990 time frame. The need for a modern data transfer system of the size and capability of SDMS has been increase in unison with the sophistication of shipboard electronic equipment and the associated magnitude of equipment-to-equipment signal traffic. Instead of the miles of unique cabling that must be specifically designed for each ship, SDMS will meet information transfer needs with general-purpose multiplex cable that will be Installed according to a standard plan that does not vary with changes to the ship's electronics suite. Perhaps the greatest impact of SDMS will be the decoupling of ship subsystems from each other and from the ship. Standard multiplex interfaces will avoid the cost and delay of modifying subsystems to make them compatible. The ability to wire a new ship according to a standard multiplex cable plan, long before the ship subsystems are fully defined, frees both the ship and the subsystems to develop at their own pace, will allow compression of the development schedules and will provide ships with more advanced subsystems. This paper describes the SDMS system currently being developed by the U.S. Navy.

Presently he is with the Communication Systems Department.

As a piezoelectric substrate for surface acoustic wave devices, the LST cut quartz has good temperature characteristics and low propagation loss. However, as the thickness of the metal electrodes on the substrate surface is increased, propagation loss also increases. Further, the electromechanical coupling coefficient is small. In this paper, a cut angle of the quartz substrate is sought that has excellent temperature stability, low propagation loss, and a large electromechanical coupling coefficient in the present of metal electrode films. For the rotated Y-cut substrate in the neighborhood of the LST cut, the propagating surface acoustic wave (SAW) merle changes from the leaky surface wave to the Love wave-type surface acoustic wave for which. no propagation loss occurs in theory while the electromechanical coupling coefficient increased to 0.5 percent at the maximum if gold is used for the electrodes and the propagation direction of the SAW is shifted from the X axis. This is shown by simulation. By experiment, it is shown that the second-order temperature coefficient is on the same order as that of the ST-cut quartz substrate.

The MK 92 Fire Control System (FCS) & a new, integrated, highly reliable and light-weight U.S. Navy Fire Control System for missile and gun control. This system, which is in production for the FFG, PCG, PGG and PHM Ship Classes, provides the detection and automation required for modern naval warfare. Search radar data & presented at a very high rate at the operator's console, a highly integrated man-machine interface. Utilization of monopulse and “track-while-scan” techniques result in multiple target tracking capability. The system console(s) offer a self-contained command and control capability and, in addition, standard digital computer channels provide the versatile interface with the ship's command and control, integrating the complete engagement process. Error cancellation techniques are employed to obtain high performance accuracy even under severe environmental conditions. The low manning requirement for both operation and maintenance is a key system attribute for all applications. Comprehensive “at-sea” evaluations, performed by the U.S. Navy, demonstrated successful system operation in all modes of surveillance, multi-target tracking and simultaneous missile and gun engagements. The “at-sea” performance record of the FCS MK 92 was cited by the Chief of Naval Operations to have established new standards for Naval Surface Weapons systems.

He worked as a Designer in the Engineering Technical Department of Newport News Shipbuilding and Drydock Co. and he sailed with a number of U.S. flag companies as an Engineering Officer. He joined the Maritime Administration in 1967 and is currently the Assistant for Program Development and Control in the Office of Research and Development. He is a member of ASNE and SNAME. Mr. Ron Corkrey:received B.B.A and M.B.A degrees from the Golden Gate University and was later a guest lecturer there and at other universities. From 1955 to 1969 he held various positions with the Matson Navigation Company ranging from Systems Analyst to Pier Superintendent. From 1969 to 1971 he was the Northern California District Manager for Signal Trucking Service Ltd. He joined the Maritime Administration in 1971 as a Transportation Specialist in the Western Region Office and he is now in Washington D. C. as Program Manager for Cargo Systems R&D. He is a member of the SNAME D31 (Cargo Handling) Panel. Mr. Larry Benen:received his B.S. degree from the U.S. Merchant Marine Academy and a M.S. degree from George Washington University. He is a graduate of the Industrial College of the Armed Forces (ICAF). He has been employed as a research program manager for the Naval Sea Systems Command since 1967 in the areas of Hydromotions and Logistics. He is presently the Program Manager for the Merchant Ship Naval Augmentation Program Exploratory Logistics Experimental Ships and Strategic Sealift Procurement Program.

Projecting our power to far corners of the earth depends on a strategic mobility triad composed of: airlift, prepositioned equipment, and sealift. Airlift can move personnel effectively and limited supplies quickly over great distances. Prepositioned equipment and supplies can extend the effectiveness of those personnel if the circumstances are right, and if we have chosen our positioning sites well. Sealift will provision the lion's share of any protracted engagement, and the ships of the Merchant Marine are a key element in our sealift resources. This paper describes various ways that the Merchant Fleet is being made more responsive to its possible role as a naval auxiliary, and it describes a new concept called SEA SHED which can quickly expand the versatility of Containerships. Containerships have revolutionized marine transportation and they now represent a large and growing portion of the Commercial Fleet. They are limited in the types of cargo they can carry, however, excluding much of the larger equipment required by military units. SEA SHED is a cargo module which fits into the cell guides of a Containership and effectively converts it to a 'tween deck, break-bulk ship which can carry almost all military equipment.

COMBAT SYSTEM INDUSTRIAL-TESTING - MEASUREMENT OF SUCCESS

引用

NAVAL ENGINEERS JOURNAL 1986年第5期98卷 47-57页

作者： TRESSLER, DL HART, JB Dennis L. Tresseler is currently combat system test team leader for the combat systems test and evaluation branch of the Naval Sea Systems Command (SEA 61 × 11). Mr. Tresseler graduated in 1972 with a degree in mechanical engineering technology. He began his career at Newport News Shipbuilding in 1972 where he was a test director responsible for weapon system installation alignment and testing in CGN-36 thru 40 and CVN-68 and 69. In 1977 he came to the Washington area and worked for various contractors in technical and managerial positions before coming to NA VSEA in 1981. He is a member of the Naval Institute and his paper on “FF-1041 Class Modernization” has been accepted for publication in the Proceedings. J.B. Hart is currently the senior program manager combat systems for VSE Corporation headquartered in Alexandria Virginia. He is the program manager for VSE's master ordnance repair (MOR) team. His previous position was with COMPTEK Research Inc. Virginia Beach as senior combat systems engineer. Mr. Hart earned his BS degree from the University of New York in general engineering. He retired as chief ordnance control warrant officer after 22 years of service in 1982. While on active duty he served in various combat systems capacities since 1968 the most noteworthy of which were as ship's combat systems test officer/fire control officer on USS Belknap (CG-26) bringing her back into commission through major reconstruction and as combat system chief onboard USS Albany (CG-10) assisting in test and delivery of the first NTDS model 4.0 software program as well as numerous control systems updates both software and hardware.

This is an overview of the combat system test and certification (CST&C) program as a subset of the total ship test program (TSTP) for active fleet surface ships. The paper will discuss how the T&C program measures not only the suitability of repairs and modifications done during a ship's combat system industrial availability in a public or private yard period, but also the impact that successful program conduct has on the materiel effectiveness throughout a ship's operational cycle. The CST&C management organization and responsibilities, including NAVSEA's master ordnance repair program as well as combat system code 190's relationship to the CST&C program and the impact of pre- and post-industrial testing requirements on the actual conduct of industrial testing will be addressed.

A modal test of the John Paul Jones (DDG-53) mainmast structure and mast-mounted antennas was conducted. The test was part of a larger effort to accurately determine dynamic characteristics of the ''as-built'' mast/antenna system and survivability in the vibration and underwater explosion (UNDEX) shock environment. Previous mathematical analysis of the DDG-51 class mast and antennas predicted response acceleration levels during a shock trials scenario to be excessive in some areas. The modal test results now provide, however, confirmed dynamic response characteristics including mode shapes, frequencies, and damping for the structure. The test data accounts for the flexibility of ship's structure including the deckhouse supporting the mast. In addition, the natural frequencies of the antennas were determined for the response range of the mast structure with the flexibility of the supporting foundations taken into account. Using the test results, a finite element model of the mast structure and antennas was built accurately representing the dynamic characteristics of the system. Dynamic transient shock analysis was conducted to provide response predictions of the mast and antennas using the validated model. Any potential response amplification conditions that might result in failure during shock trials were identified.

Maintenance is performed to restore a system's inherent reliability. However, reliability is not enough: a maintenance task must ''pay for itself'' in dollars or readiness. This applies to all types of maintenance: corrective, preventive, and alterative. We can reduce corrective maintenance costs through preventive and alterative maintenance. We can reduce preventive maintenance costs by eliminating inapplicable and ineffecitve tasks. We must weigh alterative maintenance costs against the value of improved readiness and cost-avoidance of future corrective maintenance. The U.S. Navy is improving alterative maintenance by engineering for reduced maintenance (ERM). This process corrects the root cause of some high-cost items by replacing the system, component, or coating with an improved design or material. It overcomes the limit of preventive maintenance: higher levels of inherent reliability require design improvement. The U.S. Navy is improving preventive maintenance through condition-based maintenance (CBM). The Navy's CBM initiative encompasses three parallel efforts: rules (improving maintenance requirements and plans), tools (using computer and diagnostic technology to facilitate maintenance decision-making), and schools (educating all levels of maintenance decision-makers in reliability and condition-based maintenance engineering principles). This paper addresses how the U.S. Navy surface ship community plans to avoid inapplicable and ineffective maintenance and reduce maintenance costs without sacrificing reliability.

作者： Edinberg, D Back, K McVeigh, J David Edinberg is a senior naval architect with Advanced Marine Enterprises in Arlington Virginia. His experience in ship design includes dynamic analysis of ship's deck systems intact and damaged stability calculations trim and stability support during ship designs and structural design. For the last two years he has led a team of engineers in the dynamic analysis of the sideport ramp system employed on the Navy's new sealift ships. He graduated in 1979 with a B.S. degree in naval architecture and marine engineering from the University of Michigan. Keith Back is a senior engineer with Advanced Marine Enterprises in Arlington Virginia. He is currently the section chief for the Advanced Visualization Group. He has more than ten years experience developing and using CAD models in the ship design environment. For the past two years he has led the development of visualization techniques and models for use in simulations for current ship design programs. He graduated in 1985 with a B.S. degree in aerospace and ocean engineering from Virginia Polytechnic Institute and State University. USA Lt. Col. Joe McVeigh USA is currently deputy program manager (Army) for PMS 385 the Strategic Sealift Office at NavSea. As the senior U.S. Army officer on staff he is responsible for interfacing with the program's primary customer in addition to his assignment as T&E director. Lt. Col. McVeigh graduated with a B.Sc. from the United States Military Academy in 1978 after which he received his 2nd lieutenant's commission in the U.S. Army Transportation Corps. In 1991 he received M.S. degrees in mechanical engineering and naval architecture and marine engineering from MIT. Lt. Col.

Special Forces Europe company commander 598th Medium Truck Company commander Movement Control Team Mannheim and Army watercraft systems engineer U.S.

The Navy's Sealift program had several unique problems associated with it which have been addressed using innovative modeling and simulation tech niques. These techniques fall under two categories: visualization and dynamic analysis. This paper will discuss the employment of these techniques and the impact their application has had in the program. Also examined will be various difficulties that were encountered in the application of these techniques. Commercial-off-the-shelf (COTS) visualization tools were used to model the interior Ro/Ro spaces on the four classes of new construction and conversion ships now being procured. These models were employed for vehicle maneuvering simulations, operator familiarization and visualization of the results of an analysis of the loading and unloading of Ro/Ro vehicles. A COTS dynamic analysis system was used to simulate dynamic behavior during the assembly/deplopment and retrieval/disassembly of the side port ramp using the ships' cranes. These analyses supported reviews of design configurations, proposed handling procedures, and in conjunction with extensive post-processing, operability assessments for system operation. In a parallel effort, an interactive crane simulator was developed to support on-going engineering studies, indoctrination, and test and evaluation purposes. Lessons learned have been applied to other activities at the Naval Sea systems Command. Critical areas were the validation and maintenance of up-to-date configuration data for the visual models, adaptive levels of detail to meet the requirements of each study objective, and the need to provide comprehensive documentation of models.
