Air cushion vehicles (ACVs) have operated successfully on commercial routes for about twenty years. The routes are normally quite short; the craft are equipped with radar and radio navigation aids and maintain continuous contact with their terminals. Navigation of these craft, therefore, does not present any unusual difficulty. The introduction of air cushion vehicles into military service, however, can present a very different picture, especially when external navigation aids are not available and the craft must navigate by dead reckoning. This paper considers the problems involved when navigating a high-speed air cushion vehicle by dead reckoning in conditions of poor visibility. A method is presented to assess the ACV's navigational capability under these circumstances. A figure of merit is used to determine the sensitivity of factors which affect navigation such as the range of visibility, point-to-point distance, speed, turning radius and accuracy of onboard equipment. The method provides simplistic but adequate answers and can be used effectively to compare the-capability and cost of alternative navigation concepts.

NAVAL ENGINEERS JOURNAL 1984年第5期96卷 33-45页

作者： DETOLLA, JP FLEMING, JR Joseph DeTolla:is a ship systems engineer in the Ship Systems Engineering Division SEA 56D5 at the Naval Sea Systems Command. His career with the Navy started in 1965 at the Philadelphia Naval Shipyard Design Division. In 1971 he transferred to the Naval Ship Engineering Center. He has held positions as a fluid systems design engineer and auxiliary systems design integration engineer. Mr. DeTolla has worked extensively in the synthesis and analysis of total energy systems notably the design development of the FFG-7 class waste heat recovery system. He is NA VSEA's machinery group computer supported design project coordinator and is managing the development of a machinery systems data base load forecasting algorithms and design analysis computer programs. Mr. DeTolla has a bachelor of science degree in mechanical engineering from Drexel University and a master of engineering administration degree from George Washington University. He is a registered professional engineer in the District of Columbia and has written several technical papers on waste heat recovery and energy conservation. Jeffrey Fleming:is a senior project engineer in the Energy R&D Office at the David Taylor Naval Ship R&D Center. In his current position as group leader for the future fleet energy conservation portion of the Navy's energy R&D program he is responsible for the identification and development of advanced components and subsystems which will lead to reductions in the fossil fuel consumption of future ships. Over the past several years he has also directed the development and application of total energy computer analysis techniques for the assessment of conventional and advanced shipboard machinery concepts. Mr. Fleming is a 1971 graduate electrical engineer of Virginia Polytechnic Institute and received his MS in electrical engineering from Johns Hopkins University in 1975.

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.

To meet energy conservation goals of the U.S. Navy, its attention has been focused on ways to reduce individual ship total resistance and powering requirements. One possible method of improving ship powering characteristics is by modifying existing individual ship hulls with the addition of bulbous bows. This paper will identify the merits of retrofitting bow bulbs on selected U.S. Navy auxiliary and amphibious warfare ships. A procedure for performing a cost-benefit analysis will be shown for candidate ship classes. An example of this technique for an amphibious warfare ship will also be provided. A brief discussion of future methods to be used for bulbous bow design such as application of systematic model test data and numerical hydrodynamic techniques will be given.

The finite difference-time domain (FD-TD) technique is applied to the solution of Maxwell's equations. A computer program, which can be used to simulate and study numerous electromagnetic phenomena, is developed and implemented on an IBM 386 compatible personal computer. The FD-TD technique is a useful tool for students in electromagnetics. The technique is flexible and can be applied to many basic EM scattering and radiation problems. Because field solutions are found as a function of time, visualization of the propagation of the EM fields is possible. The FD-TD technique is implemented for a two-dimensional rectangular grid in conjunction with a second-order absorbing boundary condition. Both E- and H-field polarizations are analyzed. Finite objects consisting of dielectric, magnetic and conducting materials, and perfectly conducting infinite ground planes are modeled. Plane wave and line current sources are implemented. In addition to the capability of animating the propagation of the EM fields, radiation and scattering patterns can be generated.

He moved to the U.S. in 1964 where he was the design supervisor in charge of marine engineering at NASSCO covering new construction for American President Lines AFS type ships for the U.S. Navy Project Mohole Car Ferries for the State of Washington and 17 LST's for the U.S. Navy. During the contract definition phase of the DD-963 Mr. Brice authored several portions of the technical proposal while employed by Litton industries. He was also responsible for the system and detail design including the technical management of sub-contracts for the steam propulsion plant for the LHA 1 Class ships. Mr. Brice has been active in the Washington area for the last ten years performing marine engineering projects for the U.S. Navy. His principal interest since 1974 has been in shipboard energy conservation. He assisted in the development of the NavySTMSYS program and later in the operational verification aboard FF-1074. Mr. Brice has conducted four SECA T visits aboard ships with 1200 PSI steam plants and has recently completed an at-sea visit aboard on AOR with a 600 PSI steam plant. Richard Dangel was bom in New York City. He received his Bachelor's degree from the Sloan School of Industrial Management of the Massachusetts Institute of Technology in 1955. He has also completed graduate work for a Masters in Engineering Administration at George Washington University. Since graduation he has spent 11 years in private industry with companies in the DOD engineering research

The Ship energy Conservation Assist Team (SECAT) program was initiated in Fiscal Year (FY) 82 by the Naval Sea Systems Command (NAVSEA) to demonstrate and introduce individual Ship Commands to known energy conserving techniques without adding equipment complexity or additional maintenance burden. The principal objective is to provide each ship with an energy consumption, coupled with recommended energy conservation strategies. The technique involves both in-port and underway monitoring and introduction of energy efficient machinery plant alignments, fuel consumption curve generation, and most efficient speed curves. The program has completed visits on six combatants and enjoys the support of both the Commander, Naval Surface Forces, U.S. Atlantic Fleet (COMNAVSURFLANT) and the Commander-in-Chief, U.S. Atlantic Fleet (CINCLANT). Plans are to perform SECAT on additional DDG 2 and FF 1052/1078 Class ships and initiate SECAT on additional ship types in FY 83.

The Brazilian paper industry has competitive advantages offered by the favorable climate, which favors an increase in the yield of forest restoration, and consequently, in the productive process. On the other hand, following the greenhouse gases (GHG), we can see our constantly changing sun, causing the solar storms, allowing their prevention or mitigating measures. The objective of this work is to contribute to the construction of the understanding necessary for the reduction of GHG emission from a preliminary analysis of the pulp and paper sector. As a secondary objective, the text preliminarily analyzes a company's behavior against the backdrop of the Paris Accord, which strengthens the global response to the threat of climate change and strengthens the capacity of countries to deal with the impacts of such changes. The identification of best practices in the pulp and paper industry is understood, focusing on environmental sustainability, such as the adoption of reforestation, obtaining significant results. In the case of the paper industry, the management of public forests for sustainable production, within the structure of the Ministry of the Environment, establishes the promotion of public awareness about the importance of conservation, recovery and sustainable management of forest resources.

Naval Engineers Journal 1975年第6期87卷 79-96页

作者： FAIRBANKS, JOHN W. The author is a graduate of the Maine Maritime Academy Stanford University and the University of Santa Clara. His undergraduate degrees were in Marine and Mechanical Engineering and his Masters Degree Specialization was in Heat-Mass-Momentum Transfer within the Mechanical Engineering Department He has taught Gas Dynamics Thermodynamics and Direct Energy Conversion at Texas A&M and the University of Maryland and has sailed as a licensed Marine Engineer for two and a half years with the American Export Lines currently holding active First Assistant Steam Unlimited and Third Assistant Diesel Unlimited licenses. From 1954 to 1957 he was on active duty in the U.S. Navy serving in the USS Montrose (APA-212) as both Main Propulsion Assistant and Chief Engineer. While employed at Hiller Aircraft Company he was in the Advanced Research Group and worked on the Detached Coanda Effect for VTOL and ground effect machines as well as designing high-speed bearings and high-speed shaft test stands for the SC-142A an experimental tilt wing aircraft program. In 1963 he went to Philco-Ford to design a Brayton Cycle Power System for a solar probe spacecraft and also worked on the Thermal and Power System Design of the IDCSP (DOD's Communication Satellite). At NASA's Goddard Space Center for six years his responsibilities included design fabrication integration test launch and flight operation of solar arrays on two spacecraft and also as Power Systems Engineer for the Orbiting Astronomical Observatory the largest unmanned spacecraft flown. In 1971 he joined NAVSEC where he is currently the Program Engineer on the FT9 Gas Turbine Development Program and Coordinator of the Navy's Materials Programs for advanced gas turbines. Having organized the first two Navy Gas Turbine Materials Conferences he is presently organizing U.S. participation in a joint U.S. Navy Royal Navy Gas Turbine Materials Conference to be held in ‘the United Kingdom in September 1976. Mr. Fairbanks has authored or coauthored 21 technical papers and i

The current Navy philosophy for marine gas turbine engine development is to marinize an existing aircraft turbo jet engine. The FT9 Marine Gas Turbine Engine is a 33,000 horsepower version of the Pratt and Whitney JT9D engine, which powers the 747 aircraft. Marinization of the JT9D basically involves removal of the fan section, addition of a power turbine, structural modification to several components, and material changes to provide corrosion‐resistance in the marine environment. Characteristics and ratings of the individual engine components are discussed as well as the assembled engine. The FT9 design incorporates the modular replacement concept. Modular replacement permits replacement of short‐life components such as the hot‐section without removing the engine from its mounts. The FT9 specification requires development of a condition monitoring system as an integral part of the engine development. Thus, provisions for sensor installations are incorporated in the design. Accelerometers are installed on the internal engine bearing housings to provide improved vibration signals. These accelerometers are mounted on rods such that they are removable without engine disassembly. Extensive borescope provisions are included to provide capability to inspect all hot‐section components without disassembling the engine. The engine life‐limiting component is the hot‐section because of the susceptibility of the blade and vane materials to sulphidation/oxidation at the temperatures encountered with the advanced engines. Sophisticated Made and vane cooling is used to allow high turbine inlet temperatures while keeping blade metal temperatures in a region where sulphidation/oxidation is only moderately active. Coatings are added to blades and vanes to extend engine life. Three FT9 engines will be delivered to the Navy. The target date for provisional Service Approval of FT9 is mid‐1978. FT9 will provide the U.S. Navy with the most advanced marine gas turbine with the highest powe
