SHIPBOARD STOWAGE OF FLAMMABLE AND COMBUSTIBLE LIQUIDS

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.

ELECTRONICS AND COMMUNICATIONS IN JAPAN PART III-FUNDAMENTAL ELECTRONIC SCIENCE 1995年第10期78卷 37-45页

作者： Kiya, H Nishikawa, K Ashihara, K Faculty of Technology Tokyo Metropolitan University Hachioji Japan 192-03 Members Kiyoshi Nshikawa graduated in 1990 from the Department of Electrical Engineering Tokyo Metropolitan University where he completed the Master's Program in 1992 and affiliated with Nippon Steel Co.

The subband adaptive system, where the idea of the filter bank is applied to the adaptive filter, has a feature that a higher-order adaptation can be reduced to lower-order adaptations. The reduction of the order of the adaptive filter is related closely to the number of channels and the decimation ratio. The order of adaptive digital filter (ADF) is decreased greatly when the number of subbands is increased, and the decimation ratio is increased up to the maximum value. Then, however, the number of coefficient-updates per unit time is decreased, which results in the deterioration of the convergence Speed. From such a viewpoint, this paper discusses a method to improve the convergence speed, which is deteriorated in the subband adaptive system, due to the decimation. The idea of the proposed method is to utilize effectively the data which have been discarded in the decimation process and to improve the convergence speed. It is called the multirate repeating method. As the first step, the multirate repeating method is applied to the conventional subband adaptive system and the convergence speed is improved. Then a subband adaptive system is introduced in which the multirate repeating method can be utilized more effectively. As a result, a faster convergence is realized while retaining the ADF order-reduction effect, which is an advantage of the subband adaptive system.

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 most 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.

The surface effect catamaran incorporates twin high length-to-beam cushions to support a low length-to-beam platform. The performance characteristics of the resulting vehicle, i.e., the resistance and head sea motions, are equivalent to a higher length-to-beam surface effect ship. The high lateral stability which results from the widely spaced hulls and cushions of the surface effect catamaran provides several advantages not inherent in conventional surface effect ship configurations. These advantages are manifested by high cross-structure height and reduced structural loads without reduction in static or dynamic roll stability. For an 800-ton ship the widely spaced cushions provide a capability of controlling off-head sea types of motions and the virtual elimination of green water over the deck up through Sea State 6. Model tests have validated cushionborne and hullborne resistance computer prediction programs. Head sea motions tests have justified the use of high cross-structure height to minimize high slam types of structural loads. Preliminary design and model tests indicate the potential for the surface effect catamaran to operate as an open ocean ship in smaller sizes than heretofore thought possible. In addition, its planform and large volume provides pay-load capabilities of much larger ships.

This paper proposes a method for analyzing the transient and steady states of a sine wave oscillator circuit with reactive elements which have large differences in their values. The circuit equation is represented by an autonomous nonlinear differential equation with the values of these elements. First, we describe the method for solving numerically the differential equation regardless of the stiffness by the asymptotic method developed by Krylov, Bogolyubov and Mitropolskiy. Second, we present the method for obtaining solutions of the differential equation with regard to the stiffness by combining the asymptotic method with numerical integration.

The many varied types of engineering plants extent in today's modern Navy requires an ever creasing range and depth of operational knowledge by engineering personnel at all levels of shipboard operations. The engineering Operational Sequencing System (EOSS) provides each of these levels with the required information to enable the engineering plant to respond to any demands placed upon it which are within its design capability. The engineering Operational Sequencing System is a set of systematic and detailed written procedures utilizing charts, instructions and diagrams which provide the information required for the operation of a shipboard propulsion plant. The purpose of this paper will be to define and discuss the EOSS; to describe the system background, current status and future implementation plans.

THE EVOLUTION OF MACHINERY CONTROL-systems ABOARD UNITED-STATES-NAVY GAS-TURBINE SHIPS

引用

NAVAL ENGINEERS JOURNAL 1989年第3期101卷 102-113页

作者： PREISEL, JH The author:is the DDG-51 program manager at the Naval Ship Systems Engineering Station in Philadelphia. He graduated from the U.S. Naval Academy with a B.S. in marine engineering in 1972 and completed graduate studies at the Naval Postgraduate School in 1978. In addition to an initial sea tour aboard a destroyer he has served at Charleston Naval Shipyard and at NavSea in both ship design and modernization. He recently completed a short assignment as the NavSea representative at the G.E. Simulation and Control System Department during the design manufacturing and testing of the DDG-51 Machinery Control System. Commander Preisel is a member of ASNE Sigma Xi ASME and SNAME and is a registered professional engineer.

Almost 25 years ago, the U.S. Navy committed to gas turbines for propulsion and electrical power generation for surface combatants. Jet engines from the aerospace industry were “marinized” and specified for several designs. Today, there are over one hundred gas turbine powered surface ships; almost half also have gas turbine generators. This fundamental change, notably from steam to gas turbine power, brought with it a new philosophy in the way prime movers are controlled and monitored. Unmanned engineering spaces were a fundamental part of the new design. Direct thrust control in the hands of the helmsman was possible. Possibly the most profound effect was the introduction of electronics in the main engineering spaces on a large scale. Data buses for data logging and bell logging were used as a means to reduce the tedium of normal watch standing. Gas turbine machinery control systems have entered a second generation with the introduction of the DDG-51 class destroyer and the AOE-6 supply ship. Hard-wired analog interfaces have given way to digital interfaces over asynschronous multiplexed data buses. Dedicated pushbuttons and indicators have given way to keyboards and plasma displays. Single use microprocessors with firmware coding have given way to standard microcomputers and general high order language (HOL) software code. This paper will trace the control systems' evolution from the Spruance and Perry classes to today's gas turbine designs. An attempt will be made to draw a sense of direction from this evolution. An in-depth explanation of the DDG-51 control system will be offered, as well as suggestions as to the future of control systems for gas turbine ships. Particular emphasis will be placed on the man-machine interface and the maintenance philosophy for both the control system hardware and software.

A method to estimate the refractive index profile of an optical waveguide exists in which the optical intensity distribution of the only one propagation mode is used. Since this method requires only a microscope and a television camera, setup is extremely simple and inexpensive, thereby making the method practical. The differential processing method and the inverse analysis method have been proposed as methods to use the optical intensity distribution of only one propagation mode. The mechanisms of these methods that use the optical intensity distribution are presented in detail here. As a consequence, a new method that overcomes the difficulties in the previous methods, to be called Improved Inverse Analysis Method with Fewer Parameters, is proposed. Further, by using this proposed method, the index profiles of the step-index type optical fiber and the buried optical waveguide can be estimated in order for validity of the method to be studied.
