SURFACE SHIP COMBAT SYSTEM UPGRADE engineering

NAVAL ENGINEERS JOURNAL 1988年第3期100卷 180-193页

作者： HOLDEN, RA The author is a physicist in the Systems Engineering Branch Aegis Ship Combat Systems Division at the Naval Surface Warfare Center (NSWC). He received a B.S. degree in physics and mathematics from Arkansas Polytechnic College in 1965 attended graduate school at Southern Illinois University and University of Illinois receiving a M.S. degree in physics in 1967. He was an electro optics engineer for Delco Electronics before joining NSWC in 1972. He worked as a physicist in naval weapons guidance and control technology from 1972 until joining the Aegis shipbuilding program in 1983. Currently he serves as a combat system engineering group leader supporting the Aegis Program Office (NSWC). In this position he is responsible for a task supporting the Aegis Project Office (PMS-400) for present and planned combat system R&D.

Construction of new ships is typically limited to a rate of two to five per year. The lead ship of a class requires several years for design and construction and follow-on ships are completed at the typical production rate. The total time period to complete a class of multimission surface combatants is fifteen to twenty years. As ships are constructed the combat system gradually falls behind in warfighting capability and may be changed piecemeal in an attempt to keep pace with the advancing threat. Piecemeal changes are costly and create a proliferation of equipments and configurations. An acquisition strategy is described which avoids the annual capability upgrades but provides introduction of state-of-the-art technology at preplanned points in the building program. This will insure maximum commonality and modernization. Defining preplanned combat system upgrades consists of engineering conceptual systems as a departure from real systems under development. For modern integrated combat systems such as Aegis this requires evaluating all changes in terms of total impact on the functional and physical characteristics of the system. This paper describes an approach which defines combat system configurations as baselines and periodically evaluates emerging technology to define new baseline configurations. The configurations defined in this manner insure maximum commonality among ships of the class and still maintains warfighting capability.

A COMPUTER-MODEL FOR DAMAGE TOLERANCE ANALYSIS

引用

NAVAL ENGINEERS JOURNAL 1988年第5期100卷 59-68页

作者： FAIRHEAD, DL COHEN, SL Steven L. Cohen:heads the Survivability and Damage Control Office at the David Taylor Research Center. His career has addressed a wide range of technical and management responsibilities in the areas of HM&E systems design magnetic signatures system safety of surface ships and submarines shipboard energy conservation RDT&E (future fleet) life cycle costing survivability damage control CBR defense and management information systems. He has participated in all phases of the ship design process from conceptual design through ship construction operational evaluation and overhaul/modernization. Mr. Cohen is a graduate of Drexel University where he majored in electrical engineering and has more recently taken courses in the fields of systems engineering program management costing and microcomputer-based information and decision support systems.

A computer model is being developed by the David Taylor Research Center (DTRC) to analyze the tolerance of surface ship combat systems to combat-induced and self-inflicted damage. The work is being done in support of the Navy's hull, mechanical and electrical design effort to improve the survivability of surface ship combat systems. The DDG-51 Detailed Design Specifications (Section 072f) and the General Specifications for Ships of the U.S. Navy (1986 Section 072e) both require that damage tolerance analyses be performed. A damage tolerance analysis shows the effect of damage on vital auxiliary and electrical systems and relates these damage effects to the capability of the ship to continue performing its combat mission at a prescribed level. Designated the Computer Aided Design of Survivable Distributed systems (CADSDiS) model, DTRC's deterministic analytical tool consists of portable software to be used by personnel at the activity responsible for the ship design. The model's graphics electrical module is now operating on Digital Equipment Corporation VAX computers at several Navy and commercial activities. Because CADSDiS is highly interactive, it becomes an integral part of the design cycle; this is its major benefit. Thus, damage tolerance analysis information is available to personnel designing the ship within hours or days rather than weeks or months. This computer model will help ensure that the survivability principles of separation and redundancy are incorporated into ship design and are realized in the ship as built.

引用

NAVAL ENGINEERS JOURNAL 1988年第3期100卷 204-214页

作者： BOOTH, RJ The authoris a senior specialist system engineer in the Sea Lance Program Defense Systems Division Boeing Aerospace Company Seattle Washington. He received his B.S. in 1960 from the U.S. Naval Academy and later a naval engineer degree and a M.S.M.E. degree from Massachusetts Institute of Technology in 1967. Prior to graduate school he was trained in nuclear power and served on USSSargo(SSN-583). After graduate school he served in various engineering duty officer billets at Supervisor of Shipbuilding Groton Conn. Mare Island Naval Shipyard Ship Repair Facility Yokosuka Japan and Puget Sound Naval Shipyard. Upon retirement from the Navy in 1980 he consulted for Tracor Inc. and prior to joining Boeing Aerospace Company was with John J. McMullen Associates Inc. from 1981 to 1985. He is a registered professional engineer in the state of Washington and besides ASNE he is a member of SNAME and ASME. He presented a paper on 3-M systems at ASNE day 1980.

The developmental Sea Lance Weapon System is an encapsulated supersonic standoff antisubmarine warfare missile, launched from an attack submarine torpedo tube. The buoyant capsule rises to the surface, broaches, the forward closure separates, and the rocket motor ignites, powering the missile and payload from the capsule to the target coordinates. This paper emphasizes the system engineering and naval engineering aspects of the Sea Lance capsule, a lightweight high strength composite material pressure hull. Performance, environmental and interface requirements were identified to which analyses and comparisons were made. Concept development tradeoff studies comparing different methods of launch, materials, and structural geometry led to reasons that drove selection of a composite material for the capsule. Encapsulation, buoyancy, and underwater propulsion concepts with advantages and disadvantages of each concept are compared. Determination of expected shock loads and the derivation of requirements this placed on the capsule to protect the missile are covered. Capsule requirements imposed by transportation and handling, submarine weapon shipping, and torpedo tube launch are explained. The capsule cylinder material is a layered composite material with a pressure vessel sandwich layer consisting of filament wound graphite-epoxy skins with phenolic honeycomb in between, overlaid with a damage resistant layer of filament wound Kevlar over a crushable honeycomb. Future marine possibilities of composite capsule applications are presented. The paper concludes with the naval engineering advantages of composites capsules.

Some fairly radical changes to the naval ship design process occurred during the 1970s. The decade of the 80s has also witnessed a steady stream of changes. One of the most significant was the establishment of the Ship Characteristics Improvement Board (SCIB) in the Office of the Chief of Naval Operations (OpNav), and the resulting influence on the dialog between the military requirements decision makers and the Navy's ship designers. Other changes have occurred for which the impacts are less clear. These include establishment of the chief engineer of the Navy (ChEng) position, creation of the Space and Naval Warfare systems Command (SpaWar) and OpNav's “Revolution at Sea” initiative. This paper will describe and discuss these and other changes, and comment on the resultant impact. The authors will attempt to present a global view of the total pattern of changes and try to discern if we are on a path of revolution, or merely normal evolution.

This paper describes an improvement of the solution by Krawczyk, Moore and Jones (KMJ algorithm) for nonlinear equations based on the interval analysis. When the KMJ algorithm is applied to practical problems such as the determination of the operating point of a multistable electronic circuit, a large computation time is required. It is shown that the algorithm can be improved in the computation time by a preprocessing and an elaboration in the region partitioning.

THE IN-TANK OIL-WATER SEPARATOR

引用

NAVAL ENGINEERS JOURNAL 1986年第3期98卷 209-215页

作者： WILLNER, NB DAIGNEAULT, KD Norman B. Willnerhas been employed by the Naval Sea System Command (NA VSEA) for the past five years as a program manager in the Oil Pollution Abatement Branch. His responsibilities include the design development and installation of shipboard systems to control oily waste. He is also the task leader for environmental pollution control systems for the AOE-6 and YFRT ship designs. After attending the University of Maryland Mr. Willner worked as an engineer for the National Bureau of Standards General Services Administration and the U. S. Forest Service. Mr. Willner is a member of ASNE and ASME. Kevin D. Daigneaultis currently working in the Fluid Systems Division of M. Rosenblatt & Son Inc. A graduate of Maine Maritime Academy he received a bachelor of science degree in marine engineering with a minor degree in engineering science. A U.S.C.G. licensed 3rd assistant engineer Mr. Daigneault has experience working with shipboard oil/water separator and sewage systems as well as municipal and residential pollution abatement systems. He is an ASNE member.

Recently enacted public law and international treaties prohibit the discharge of oily wastes from oceangoing ships. To comply with these laws, the U.S. Navy and the Department of Defense (DOD) have issued a directive implementing standards for the prevention of oil pollution from U.S. Navy ships. Because of unique equipment and system design requirements for combatant and auxiliary ships in the U.S. Navy, research and development (R&D) was initiated to develop oil/water separator (OWS) systems. Over the past ten years, three systems were developed that met the Navy's requirements and are currently installed aboard Navy ships. Recently, a new generation of oil/water separator was conceived. Using existing oil coalescing theory and equipment already in the fleet, an in-tank oil/water separator (ITOWS) was developed. This new separator, installed aboard a naval combatant for testing, has met or exceeded all system requirements. Following a satisfactory operational evaluation by an independent U.S. Navy test command, the ITOWS will be specified for installation aboard new U.S. Navy ships. This article reviews current U.S. Navy OWS designs and introduces the ITOWS system currently undergoing final evaluation.

SHIPBOARD STOWAGE OF FLAMMABLE AND COMBUSTIBLE LIQUIDS

引用

NAVAL ENGINEERS JOURNAL 1986年第3期98卷 199-208页

作者： DROPIK, MV graduated from the University of Detroit in 1969 with a bachelor of science degree in mechanical engineering. He began his Navy career that year with the Naval Ship Systems Command PMS-382 Ship Acquisition Manager for Mine Patrol and Yardcraft. In 1971 he transferred to the General Arrangements and Habitability Design Branch of the Naval Ship Engineering Center. From 1971–1972 he attended graduate school at the University of California at Berkeley through the Navy's long-term training program and received his master's degree in industrial engineering. He currently heads the Auxiliary/Amphibious/Minecraft/Special Projects Branch of NAVSEA's Arrangements Design Division. His duties in this capacity include those of program manager of the U.S. Navy's flammable liquids program a position which he has held for the last eight years. His experience encompasses the general arrangements habitability storeroom and office design of aviation auxiliary amphibious mine warfare and high performance ships and craft.

The uncontrolled proliferation of flammables and combustibles aboard ship, in addition to posing an obvious fire and explosive hazard, has seriously degraded the survivability and increased the vulnerability characteristics of U.S. Navy surface ships. This problem for the most part has been superficially attributed to a widespread shortage of flammable and combustible stowage capacity. As a result, current solutions have been limited to increasing stowage capacity through additional storerooms and development of more efficient stowage aids. Unfortunately, these solutions simply address the symptoms, are of a corrective nature, and do not eliminate the fundamental causes of the problem. The paper conducts a more systematic and comprehensive investigation into identifying and resolving the flammable liquids problem by considering it from a ship life cycle perspective. In this way, the problem is shown to be the resultant accumulation of a number of causes which occur during a ship's design, construction, and operational phases, and which collectively manifest themselves as a major shortage of flammable and combustible liquid stowage space aboard current fleet ships. Actions are then formulated to eliminate or counteract these fundamental causes, and validated by application to a hypothetical case study.
