While most of the theater ballistic missiles (TBM) in threat countries' inventories are of the shorter range SCUD varieties, mid- to long-range versions are currently in development in a number of third world countries. Threat potential exists in the following three battle spaces: endo-atmosphere (0-30 km), high endo-atmosphere (30-70 km) and exo-atmosphere (greater than 70 km). The inherent short range and low speed of endo-atmospheric threats match well with capabilities of SM-2 Block IVA, which equips the Navy with an area defense capability The exo-atmospheric TBMs are longer range and can threaten more targets which may be widely dispersed. Their higher velocities reduce response times dramatically Therefore, exo-atmospheric TBMs create the need for Standard Missile-3 (SM-3), which provides the Navy with theater wide defense capability. Defining its area and theater wide systems as clearly endo-atmospheric and exo-atmospheric systems allows the Navy to use derivatives of the Standard Missile Block IV to take full advantage of the conditions associated with each of these operating zones. Use of an existing missile and ship system baseline also allows use of the existing interface structure to minimize cost. To counter the endo-atmospheric TBMs, the SM-2 BLK TVA upgrades include an advanced imaging infrared (IIR) seeker, an improved fast-reaction auto pilot and a forward looking RE all in the same volume as the existing missile. The highly responsive SM-2 Block IVA missile, complemented with Aegis weapons systems modifications, provides capability against enemy aircraft and cruise missiles, as well as TBMs. Standard Missile-3 (SM-3) replaces the SM-2 Block TV warhead, radar and guidance section with a boosted third stage and an advanced kinetic warhead (KW). Operation in the exo-atmospheric region permits a KW design with autonomous guidance control and divert thrusters for high maneuverability and has the capability of achieving very high interceptor velocities.

作者： Ishikawa, M Kyogoku, A Umoto, J Kyoto University Dr. of Engineering degree in 1976 from Kyoto University. He became an Associate Professor in the Department of Electrical Engineering of the Faculty of Engineering in 1984. He has been engaged in research on energy conversion especially in MHD power generation. He is a member of the Japan Society of Plasma Science Atomic Energy Society of Japan and American Institute of Aeronautics and Astronautics. Master's degree in Electrical Engineering in 1994 from Kyoto University. He joined Matsushita Electric Industrial Co. Ltd. in April 1994. Completed his Dr. of Engineering degree from Kyoto University in 1958. He became a Professor of the same university in 1967. He has been engaged in research on traveling waves in power systems transient stability MHD power generation and electrical apparatus. He is currently a Professor at Fukuyama University.

Stability of large-scale coal-fired MHD channels is studied by (1) linearized stability analysis, and (2) time-dependent I-D analysis. The channel length is 15 m with 600 electrode pairs, and the output power ranges from 220.6 MW through 258.7 MW. Linearized stability analyses show that the Faraday channels operated with fixed loading resistance are stable, whereas the two waves of u and u - a (u, a: gas and sound velocity) become unstable in the Faraday channel with fixed loading factor. Two waves of u and u - a are unstable in the diagonal channel with fixed loading current and the u + a wave becomes unstable in the diagonal channel with fixed electrode current. Time-dependent one-dimensional analyses indicate that the Faraday channels with fixed load resistance are smooth without growth of fluctuation. The diagonal channels with fixed electrode current are smooth with no fluctuation, though the linear theory indicates that the u + a wave is unstable. The diagonal channel with fixed load current suffers large disturbance along the latter half of the channel, being consistent with the linearized analysis which indicates that the u - a and u waves are unstable.

A new transient stability controller system (TSC) based on on-line transient stability calculation has been developed. The TSC system prevents the power system from wide-area blackout by shedding generators optimally when a serious fault occurs. This system consists of a central processing unit (TSC-P), and four local units for fault detection (TSC-C), and seventeen units for generator shedding(TSC-T). The TSC-P selects optimal generators to be shed for stabilization based on on-line transient stability calculation for contingencies at 500 kV lines and buses every five minutes. The results are transmitted to the TSC-Cs periodically. Should any fault occur, only one TSC-C will detect the fault occurrence and send control signals to the TSC-Ts which actually generate shedding signals. To realize the TSC system, essential are fast stability evaluation methods for a large number of contingencies and effective selection methods of optimal generators to be shed for stabilization. This paper presents total algorithms applied in the TSC-P, the results of algorithm verification tests using a prototype system combined with a large-scale analog simulator, and the characteristics of the actual system.

Sodium-immersed electromagnetic pumps will be critical for commercialization of fast breeder reactors in the near future. In order to operate the pumps in molten sodium satisfactorily, it is indispensable to have electrical insulation that can withstand temperatures of above 500 degrees C for a prolonged period of time. Several mica-alumina composite insulation types were aged under a high electric field in nitrogen at high temperatures. All composite insulations aged at 750 degrees C experienced dielectric breakdown after around 1000 hours. However, it was possible to detect the onset of dielectric breakdown by monitoring the ac current. Mica splittings insulation was found to be superior in dielectric performance to mica paper insulation. Thermal degradation contributed to the dielectric deterioration of these insulations.

Over the past three years the Carderock Division of the Naval Surface Warfare Center (CDNSWC), under the auspices of the Naval Sea systems Command (NAVSEA), has investigated the possibility of replacing conventional Hull, Mechanical and electrical (HM&E) sensors with their fiber optic counterpart. The goal of the Navy in this effort is to provide the shipbuilder with specifications for fiber optic sensors that, as a minimum, meet the current performance level of conventional sensors and decrease life cycle costs. The approach of this effort has been to investigate commercially available sensors and write specifications that incorporate the Navy's needs and industry's capabilities. In order to accomplish this task, a comparison of conventional versus fiber optic sensors was conducted. This paper describes the work performed as well as the anticipated future of fiber optic technology in each of the sensing areas.

The paper discusses how current and voltage measurements derived from the substation can be used for single‐phase‐to‐ground fault location in medium‐voltage distribution lines. The networks considered are assumed to be radially operated with either an isolated or compensated neutral. In these networks the fundamental frequency ground fault currents usually are so small that no reasonable fault‐distance estimate can be based on them. A possible solution is the utilisation of ground‐fault initial transients. In this paper a method for ground‐fault distance estimation, based on the least squares estimation of transient parameters, is presented. Copyright © 1995 John Wiley & Sons, Ltd.

This paper describes a computer program for generating finite element meshes for electron guns. Two new methods, the 'projection' and the 'mesh density function' methods, are used to generate the mesh. The new methods enable the mesh distribution to be set smoothly and changed easily, and also enable the mesh distribution to be adjusted according to parameters associated with the gun configuration or by feedback from the electric field calculation. The new program, which can handle a large variety of complicated electron gun structures, has been used in conjunction with the SOGUN program which has been developed by Zhu and Munro for electron gun simulation.

Broadband integrated networks based on asynchronous transfer mode (ATM) technology are being proposed to provide a single integrated access to a variety of services and applications. Constant bit rate services will form an important part of this unified networking solution. In this paper, we identify and describe the relevant aspects related to the implementation of CBR services on ATM. First, we identify two broad categories of potential CBR services for broadband ATM networks. The ATM infrastructure for the identified services is then developed along with the required functionalities of different network elements. Finally, end-to-end performance objectives for the ATM network are determined and verified empirically based on results of laboratory experiments. These performance objectives help us determine the minimum QOS required by the highest class of service category offered by an ATM network.

There is a very large demand for basic telephone service in developing nations, and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routeing, and light spacecraft technology, in part based on the work of the Jet Propulsion Laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centres of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide a service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain these economies of scale requires that the system use K(alpha)-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st Century.

A general solution is presented for the probability density function of the amplitude of the sum of a number of harmonics from different sources. In the solution, the phase angles and amplitudes of component vectors may vary randomly in any given range. If these variation ranges are the same for all the component vectors, then ‐ in addition to them ‐ only arithmetic and geometric sums of the maximum amplitudes need to be known in order to calculate the parameters of the probability density function.
