作者： BROWN, DW REPP, JR TAYLOR, OS D. W. Brown is an engineer at the Westinghouse Research and Development Center. He received a B.S. in mechanical engineering from Michigan Technological University and an M.S. in mechanical engineering from Michigan State University. Mr. Brown joined Westinghouse in 1986 and has since worked on such projects as the testing and analysis of current collection apparatus the design of shaft and bearing arrangements for high speed electrical motors and the design of a submersible electric motor. He also has experience in the use and analysis of fiber-reinforced composites at room temperature and at cryogenic temperatures. This knowledge of composites was applied to a study involving a fibrous composite robot arm. Mr. Brown is working on the rotor design of a cryogenically cooled AF generator and also the design of the vertical motor test facility for the Motor Silencing Program. Jeffrey R. Repp is a senior engineer with Westinghouse Research and Development Center. He received a B.S. in electrical engineering from Pennsylvania State University an M.S. in electrical engineering from the University of Cincinnati and an M.B.A. in management/industrial management from Xavier University. Mr. Repp has 13 years of experience in the field of electrical engineering specializing in the design and analysis of electromagnetic devices. This experience includes the development design testing and analysis of a wide variety of electric motors ranging from fractional horsepower permanent magnet motors through large (10000 hp) synchronous and induction motors. Mr. Repp has been directly involved in the electromagnetic and thermal analyses of machines utilizing state-of-the-art finite element and computer graphic techniques. Most recently he has been concerned with the development of electronically commutated permanent magnet (brushless dc) products. Mr. Repp is a Member Institute of Electrical and Electronics Engineers IEEE Power Engineering Society. O. S. Taylor is manager of electromechanical applications at the Westin

Mr. Taylor has more than 18 years of experience in the field of research and development engineering. Since joining Westinghouse in 1974 he has been involved in the design and development of advanced electrical machinery including large, high power density motors for electric drive ship propulsion, pulsed homopolar generators for electromagnetic launchers, high current density contacts for switching applications, research in automated manufacturing, and robotic system development. He is currently managing a section that deals with rotating power equipment for military applications, with emphasis on thermal and electromagnetic modeling. ABSTRACT A demonstration submersible outboard electric motor/ propulsor has been designed, built, and successfully tested. This concept involves mounting a propeller directly inside a rotor of a specially designed induction motor. This motor/ propulsor has the advantages of direct seawater cooling and bearing lubrication, direct drive, shrouded propeller, variable positioning, easy access, and high maneuverability. The motor/propulsor is readily adaptable to dual, independently-controlled and contra-rotating propellers without the need for gears. The concept has been investigated conceptually for application to primary propulsion, secondary propulsion, and pod drives, for amphibious, surface, and undersea vehicles.

He has held several engineering positions in the areas of Design. Development. Simulation and Test & Evaluation of both antenna systems and avionics systems. He did his graduate study in Electromagnetics at Ohio State University and has authored several technical papers and numerous reports. Currently. he is Project Engineer for the development of an Adaptive Array Antenna to be used with future communication systems such as JTIDS. Mr. W. 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.

In this paper, a methodology and guidelines for applying risk methods in design and operation of maritime systems were developed and demonstrated using a case study of marine diesel generators. The methodology consists of several modules that include system definition based on functional and performance requirements, definition of dependencies among subsystems, data collection and reduction, reliability and risk analyses, and results reduction for use in decision analysis. The methodology was used to assess and analyze typical service diesel generators found onboard ships. The analysis included the generation of cut sets for the overall reliability of the system. The most likely failure scenarios were determined by demonstration as the failure of fuel supply components. The results are consistent with previous findings of the U.S. Coast Guard.

This paper provides a context within which the role of human factors engineering (HFE) for Naval ship design may be understood. HFE is defined and its history as part of engineering design teams is traced. The role of HFE in ship systems design is defined, and the HFE Technology for Ships program, managed by SEA 061R, is described. The rationale for inclusion of HFE in the design process is presented, the methodology whereby it is incorporated into the design process is detailed, methodology to assess the application of HFE is outlined, and the benefits that will accrue as a result of inclusion of HFE considerations in the design process are documented. The counterpoint to inclusion is illustrated through instances of design-induced human errors. A specific application of HFE in the acquisition process is illustrated through use of the Landing Craft, Air Cushion HFE program plan. The difficulties which may be encountered as the size of the target system expands are described. Potential roadblocks to the required incorporation of HFE are examined for their source and possible ameliorative steps.
