In support of the Navy's efforts to improve the energy usage of future ships and thereby to reduce fleet operating costs, a large scale computer model has been developed by the david Taylor Naval Ship research and development Center (dTNSrdC) to analyze the performance of shipboard energy systems for applications other than nuclear or oil-fired steam propulsion plants. This paper discusses the applications and utility of this computer program as a performance analysis tool for design of ship machinery systems. The program is a simulation model that performs a complete thermodynamic analysis of a user-specified energy system. It offers considerable flexibility in analyzing a variety of propulsion, electrical, and auxiliary plant configurations through a component building block structure. Component subroutines that model the performance of shipboard equipment such as engines, boilers, generators, and compressors are available from the program library. Component subroutines are selected and linked in the program to model the desired machinery plant functional configurations. The operation of the defined shipboard energy system may then be simulated over a user-specified scenario of temperature, time, and load profiles. The program output furnishes information on component operating characteristics and fuel demands, which allows evaluation of the total system performance.

The FFG 7/LAMPS MK III Operator Guidance Manual (OGM) was developed for all FFG-7 class frigates which are not fin stabilized or are operating with the fins off. The OGM was developed to assis the ship operators of the FFG-7 class in choosing ship speed and heading combinations which will minimize ship motion-related problems during various phases of the LAMPS deployment. Crew safety and performance were major concerns in the development of the OGM. This paper reviews the effect of human factors on ship operations during helicopter recovery, maintenance, and transit to and from the hangar.

作者： BELL, Gr The Authoris currently the Director of Advanced Programs (Defense) with ORI Inc. He graduated from the U.S. Naval Postgraduate School (BS and MS aeronautical engineering) in 1963 and achieved an MS (systems management) from the University of Southern California in 1977. He joined the U.S. Navy as a Midshipman in 1947 earned his wings as a naval aviator in 1950 and was commissioned in 1951. He served several flying tours including a Korean combat cruise with the carrierPrincetonand a tour instructing Vietnamese pilots at Bien Hoa airfield. He was designated an Aeronautical Engineering Duty (AED) Officer and spent his first tour as a commander at the Bureau of Naval Weapons serving as the Deputy Project Manager for the F-14 Phoenix Missile System Project during full scale development. His next tour was spent in Brussels as Director International R&D Navy Armaments USNA TO. His last operational tour was spent as Assistant Chief of Staff Material Readiness Commander Task Force 77 during the last year of U.S. involvement in Vietnam. He returned to a double hatted tour with the Naval A ir Systems Command and the Bureau of Naval Personnel as the AED captain detailer and career manager. His final Navy tour was served as the project manager for antiradiation missiles. Upon retirement in 1975 as a captain he entered the civilian sector as an engineer working for Systems Consultants Inc. In 1978 he joined Computer Sciences Corporation and was made the manager of the CSC omnibus contracts at Patuxent River Maryland. In 1981 he joined his present company ORI Inc. and has served as division director primarily providing support to the Joint Cruise Missiles Project for Tomahawk weapons system integration in battleships DD-963 class VLS/Aegis and CGN class ships.

The enormity of the task of reactivating a forty year old battleship, the USS New Jersey , for the fourth time, outfitting her with new technology surface warfare and strike capabilities, improved self defense weapons and modernized communications installations at minimal cost during a fifteen month industrial period is described in this paper. Challenges involved included the Tomahawk weapons system design modifications necessary to enhance the capabilities of the not yet operational eight missile Spruance class destroyer baseline configuration to a thirty-two missile battleship suite. Incorporation of the Tomahawk system brings to this venerable dreadnought the capability of operating offensively with battle forces in the highest threat areas and conducting offensive operations against surface ships and targets ashore, using Tomahawk land attack and antiship missiles (ASM). The revitalized New Jersey also provides self-defense against ASM and attacking aircraft at short range. The design of her combat system remains in consonance with the original attributes of the ship's design—sur-vivable, dependable, and redundant. This paper examines the adaptation of the Tomahawk weapons system for installation in New Jersey . The design modifications have been particularly critical, since the baseline system is currently under development in USS Merrill . Urgent Navy requirements dictated that the battleship-Tomahawk effort overtake and lead the baseline development in Merrill . Emphasis in this paper is placed upon the discussion of planning, implementation, problems encountered, and the advanced capabilities surrounding New Jersey as a result of installing the Tomahawk Weapons system. Finally, the paper concludes with a discussion of the potential operational utilization of New Jersey in the strike warfare role that was lost to the surface Navy in World War II, when aircraft carriers supplanted battleships as the Navy's main striking arm.

A ship design methodology is presented for developing hull forms that attain improved performance in both seakeeping and resistance. Contrary to traditional practice, the methodology starts with developing a seakeeping-optimized hull form without making concessions to other performance considerations, such as resistance. The seakeeping-optimized hull is then modified to improve other performance characteristics without degrading the seakeeping. Presented is a point-design example produced by this methodology. Merits of the methodology and the point design are assessed on the basis of theoretical calculations and model experiments. This methodology is an integral part of the Hull Form design system (HFdS) being developed for computer-supported naval ship design. The modularized character of HFdS and its application to hull form development are discussed.

IEEE Journal of Solid-State Circuits 1982年第2期17卷 133-137页

High-pressure oxidation of silicon was performed at a pressure of 8.9 kg/cm2 at a temperature range of 650 to 950°C. The oxidation temperature dependence of the film density, refractive index, chemical etching rate, and residual stress was measured. The film density of the oxide film was found to increase with decreasing oxidation temperature. The refractive index of the film also increased with decreasing oxidation temperature. The residual stress was found to be dependent on the oxidation temperature. The dielectric breakdown strength of the oxide film was measured by the voltage ramping method. The defect density of the oxide film calculated from the distribution of dielectric breakdown strength slightly decreased with decreasing oxidation temperature. The surface-state density of the oxide film was about 1.1 × 1011 cm-2 throughout the oxidation temperature range. The oxide grown on a doped polysilicon layer at a temperature of 750°C was five times as thick as the oxide simultaneously grown on the silicon substrate. The high-pressure and low-temperature oxidation was applied to the fabrication process of a device with a double polysilicon layer structure.

A hydrodynamic vehicle design analysis of a towed environmental sensing system was conducted. The primary thrust of the analysis was to determine the towed vehicle geometry and mass characteristics which best meet the depth-keeping and stability requirements. The effect of the tow cable, depressor, and tow ship were also examined. The design requirements, initial vehicle geometry, the effects of geometry modifications, and the final vehicle geometry are presented. Longitudinal and lateral stability are presented as a function of geometry. Towed vehicle response is predicted for typical seaway and ship motion forcing functions, and the system tow performance is presented as a function of speed and depth.

High pressure oxidation (HPO) is a new technique for VLSI processing. The advantages of HPO have been reported on the high growth rate of thick oxide, which results in the improvement of oxidation time and temperature, and the remarkable reduction of OSF and impurity redistribution (1) - (4). For VLSI having a thinner insulator film and a shallow junction depth, lower temperature processing is necessary. In this paper, it will be reported that the high pressure low temperature oxidation technique is able to be applied to a thin gate insulator process.

作者： ZOVKO, CT THE AUTHORwas born in 1934 in Pittsburgh Pa. He received his B.S. degree in Chemistry from Carnegie Institute of Technology in 1956 and subsequently his Ph.D. degree in Chemistry from The Catholic University of America in 1961 his doctoral thesis being “The Transition from Deflagration to Detonation in High Explosives.” Since 1957 he has been employed at the former Naval Ordnance Laboratory and the present Naval Surface Weapons Center White Oak. Silver Spring Md. where he has been involved in R&D activities related to rocket propulsion explosives sensitivity molten salt electrochemistry torpedo propulsion. expulsion charges. gas dynamic laser fuels underwater rocketry and many other assorted investigations of chemically-fueled mechanical processes. During this period he also served on active duty in the U.S. Army Corps of Engineers for eighteen months much of his time being spent working upon computerized mapping systems. Currently he is engaged in developing the water piston propulsion system.

The paper describes several unusual propulsion systems that can be used in underwater vehicles such as torpedoes, propelled mines, anti-torpedo weapons, underwater launched missiles, submarine signals, decoys, et cetera. One of the devices also has a potential for ship propulsion. The unifying theme in this report is the principle that, at short ranges, the size of the propulsion hardware is much more important than the fuel consumption rate. This principle applies even more strongly at high vehicle speeds. An application of this idea to short-range torpedo-like vehicles led to active consideration of rockets for underwater propulsion. At short ranges, the rocket fuel and hardware are significantly smaller and lighter (considered together) than the fuel and hardware for a conventional system. A program is now being completed to develop an engineering data base for the use of rockets under water. The somewhat surprising weight and volume advantages of using rocket motors for short-range missions, despite their high fuel consumption, leads one to speculate whether or not an intermediate system can be devised that would have a small hardware weight and volume (not so small as a rocket). Such an intermediate system could have an advantage over both rockets and conventional systems at most ranges of interest. The first and most straightforward of the intermediate systems is the “Jet Tip Propeller.” It integrates a single-stage reaction turbine of the HErO type with a propeller. This integration achieves small hardware size and weight, but because of the resulting inefficiencies the fuel consumption rate is about one-hall to one-fourth as great as that for a rocket or about ten times greater than that for a conventional propulsion system. It can be shown that the fuel consumption of a rocket could be reduced dramatically if a modest flow of the ambient seawater could be added to the rocket exhaust in the “right way.” Many attempts have been made to exploit this possibilit
