Herbert Heffner Jr. is Head of the Microwave Technology Branch at NADC Wurminster. Pa. He received his B.S. degree in Electrical Engineering from Drexel University in 1962. and since then has held several design and development engineering positions at NADC and in the Naval Material Command. He attended Ohio State University during 1964 and 1965 receiving his M.S. degree in Electrical Engineering upon completion of his studies. For the past fourteen years he has been involved in the analysis. design development. and evaluation of aircraft antenna systems. radonies. and radar cross-section reduction techniques. In 1976. he was temporarily assigned as Program Element Administrator Surface and Aerospace Target Surveillance. under the Deputy Chief of Naval Material for Development. Naval Material Command. In his four years since returning to NADC. his responsibilities have included developing antennas for future Electronic Warfare and Communication Electronic Counter-Countermeasure applications as well as digital computer antenna analysis techniques and radar camouflage of tactical aircraft.

The Navy is developing an airborne adaptive array antenna for the Joint Tactical Information Distribution System (JTIDS). JTIDS is a Tri-Service multi-channel, multi-function system to provide an advanced communication, navigation, and identification (CNI) capability for a wide variety of uses. JTIDS terminals perform multiple digital voice/data functions and relative navigation as well as the standard TACAN and IFF transponder functions. The system uses a low-duty cycle, spread-spectrum waveform and advanced coding techniques to provide secure, jam-resistant, and low probability of exploitation CNI functions. Among the important factors which determine the ultimate utility of a JTIDS terminal is the performance of the antenna system. Inadequate antenna performance could seriously degrade and possibly even negate the primary platform mission. Recent advances in antenna and data processing techndogiea promise to provide JTIDS with adequate gain and pattern coverage as well as substantial AJ (Anti-Jam) margin to complement JTIDS signal processing. The desired improvement in AJ protection can be achieved by capitalizing on the spatial filtering properties of adaptive array antennas. This paper presents the “trade-offs” which must be addressed in the design of an adaptive array antenna for airborne JTIDS terminals and the design philosophy currently in development by the Navy.

Since joining CEL he has specialized in Underwater Manipulator and Diver Tool Systems has been the Project Engineer and Navy certified submersible operator for the manned submersible NEMO and has been responsible for the design test and evaluation of submersible fluid power and fluid power control systems. His most recent efforts have been on the Deep Ocean Cable Burial System for which he has been responsible for concept development program management validation testing. and coordination and planning for the total system design and fabrication. Mr. Rockwell is an Engineer-in-Training (EIT) in the state of California and in 1979 was awarded the Meritorious Civil Service Award for his outstanding performance. Mr. John H. Engel Jr. is a Mechanical Engineer in the Construction Systems Division Ocean Engineering Department. of the Civil Engineering Laboratory. He is a graduate of Oregon State University for which he received both his B.S. and M.S. degrees in Mechanical Engineering. Prior to joining CEL in 1975 he was involved with the design and development of remote oceanographic devices for the School of Oceanography at Oregon State University. At CEL he has worked in the areas of Underwater Gas Generation and Buoyant Lift Systems and at the present time is responsible for the mechanical design of the shallow water mooring for the initial ocean tests of the Current Measurement System.

Bottom fishing equipment employed by scallopers and trawlers routinely damage or break important Navy Oceanographic cables resulting in substantial repair coats and unacceptable system interruption. The Civil Engineering Laboratory (CEL), sponsored by the Naval Facilities Engineering Command (NAVFACENGCOM), has been developing and validating an engineering concept for a Deep Ocean Cable Burial (DOCB) System. This DOCB System will providethe Navy with an efficient, effective and reliable means of burying cables 3-feet deap in ocean mediments, at speeds not less than one knot, to water depths of 6,000 feet. The DOCB System b a remotely controlled machine which underruns and buries existing (previously laid) cables. It is powered and controlled from a surface ship via an electromechanical umbilica cable. The machine is self-propelled by ducted thrusters and supported on water lubricated skids. The excavation system computer an orbital vibrating plowshareand a vertical waterjet. Full-scale field testing at CEL baa keyed on three areas: •. Quantifying the reduction in drawbar force achieved by applying orbital vibration to an upward cutting plowshare. •. Evaluating a Vertically impinging jet nozzle for depth of a cut M a function of jet operating parameters. •. Demonstrating the effect on the soil drag of a flat-bottomed skid due to forcing a thin layer of water between the skid and the seafloor. The field teats of an orbital vibratory plow were performed in a 1 to 2 psi clay simllar to that found on the ocean floor. The results showed that a 70% reduction in drawbar force was achieved by applying an elliptical orbital vibration. It was also shown that the vibration feature would split or push aside buried rocks which would have stalled a conventional stationary plow. The water jet tests demonstrated that a 2 1/2-in. nozzle cuts 36-in. deep in 1 to 2 psi clay. The nozzle pressure was 75 psi and flow was 1,200 gpm. The water jet did not produce a clearly defined trench, b

Early in his career he was employed at the Navy's Bureau of Ships in the capacity of a Structural Designer and Structural Research Monitor. In 1966 he joined the Staff of the Center for Naval Analyses where he was involved in the mathematical modeling of ships and aircraft and in economic “trade-off‘ analysis. In 1970. he went to the Naval Ship Engineering Center as an Operations Research Analyst in the Ship Design and Development Division. At the present time he is employed as a Program Manager for the Naval Sea Systems Command Ship Design Research and Development Office. A member of ASNE since 1973 he also is a member of the Association of Scientists and Engineers at NAVSEA the Operations Research Society of America and the Lighter-Than-Air Society. Mr. Kenneth W.

As part of the Advanced Submarine Control program (ASCOP), the Naval Sea Systems Command has developed an open water Submarine Control System Test Vehicle (CSTV). This vehicle is a 1/12 scale model of an SSN 688 Class Submarine, with provisions for easy geometric changes. Such changes include alternate Sail size and location, the addition of parallel middle-bodies, alternative tail sections, and alternative control configurations. A self-contained instrumentation and control system provides the capability for “on-board” recording of all relevant Submarine-state variables, over the entire speed and depth range, to a degree of data accuracy exceeding any known system. With the means thus available to correlate measured vehicle hydrodynamics with selected maneuvers, conditions, and changes in hull geometry and control surface configuration, modern mathematical techniques for improving submarine equations of motion can be employed to permit dramatic design enhancements in both safety and performance. This paper provides the rationale and history of the development of this vehicle, a description of the instrumentation and control package, and a description of the vehicle itself.

Dynamic Simulation is defined as the hardware and software required to present to the student operator visual and audible cues and responses that are the same as those encountered when operating the Control Consoles aborad ship. This type of simulation is considered essential to the development of operator skills for critical tasks. Less critical tasks can be practiced using static simulation devices. This paper discusses the utilization of these types of training devices to train Navy crews. An overview of the Machinery Control Systems of the FFG 7 and AO 177 Class ships is discussed to provide an understanding of state‐of‐the‐art equipment development. The training programs for these two ship Classes are then reviewed to show how simulation devices are currently used by the Training Community, and this is followed by a brief discussion of the additional benefits that also are derived. © 1980 by the American Society of Naval Engineers, Inc.

Since the signing of the Contract Design Plane for the CVN 68 (the U.S. Navy's latest Class of Aircraft Carriers) In 1963, considerable technological advances have been made in Naval Ship Design. This paper provides specific examples of how new technology has affected traditional Carrier design practices and techniques, and also indicates areas where future advanced technology will be needed. It is divided into four sections: 1) Computer Design Application; 2) Total Ship Energy Conservation Analysis; 3) Advances in Structural Design; and 4) Impact of V/STOL Aircraft. The increased use of the computer to define ship characteristics in the initial stage of ship design is discussed, followed by a report on efforts to include energy conservation as an integral part of the design process. The energy conservation approach uses traditional analytical techniques to develop innovative design configurations that will achieve energy savings. Of the many advances in Carrier structural design, two specific examples are given: 1) Elimination of the infamous “knee-knockers” (high sills in passageway openings) common to Gallery Deck structure, and 2) Successful attempts at reducing the thickness of aircraft elevator platforms. The paper concludes by pointing out some possible challenges facing the ship designer and some of the technology already created by the expected introduction of advanced design Vertical/Short Takeoff and Landing (V/STOL) aircraft.

THE IMPROVED NAVAL SHIPYARD MANA GEMENT INFORMATION SYSTEM—A POTENTIAL FOR INCREASED PRODUCTIVITY

引用

Naval Engineers Journal 1979年第2期91卷 192-203页

作者： SISSON, JONATHAN A. USN (RET.) Capt. Jonathan A. Sisson USN (RET.) is a graduate of the United States Naval Academy and received his degree of Master of Science in Naval Architecture from the Webb Institute of Naval Architecture. From 1964 to 1969 he was the Planning & Estimating Superintendent at the Norfolk Naval Shipyard. From 1969 to 1976 he was the Director Naval Shipyard Management Systems Division Naval Sea Systems Command during which period he initiated the development of the improved Shipyard MIS. From December 1976 until his retirement from the Navy on 1 July 1978 he was the Manager Naval Shipyard Management Information System Improvement Program Naval Sea Systems Command. He joined the staff at ORI Inc. Silver Spring Md. in September 1978 and is a member of SNAME and the Society for Management Information Systems.

The standard Naval Shipyard Management Information System (Shipyard MIS) in use at the eight United States Naval Shipyards is a computer‐based system that processes data related to virtually every element of naval shipyard operations. It has had almost thirteen years of operation constantly growing and improving along the way. In early 1976 a major improvement program was initiated to modernize this batch processing oriented system to meet the needs of management for information in a more responsive manner. Some of the products of this improvement program offer the potential to shipyard managers for improving productivity. This paper describes some of these products and the challenges to shipyard management to utilize them effectively such that improved performance or productivity and significant cost savings can be realized. © 1979 American Society of Naval Engineers
