After serving as head of the Weapon Systems Division and the Search and Track Division he formed the Strategic Planning Group. In 1985 he received the Bernard Smith Award for creative development and implementation of a strategic planning process for the Division. From 1985 to 1987 he served as warfare systems architect in the Space and Naval Warfare Systems Command. Dr. Pollard is currently conducting studies in design of future shipboard combat systems.

This paper considers an effort to reinvent the process by which the Navy transforms operational requirements into warships. The objective is to articulate a framework and strategy for implementing a total ship system engineering approach. Three factors drive the effort: involve the warfighters in the design process;adopt a ''system of systems'' framework for integration;and continually improve the acquisition process. The strategy is illustrated by consideration of control structure on a total ship basis. The work has been conducted as a collaborative effort involving three Navy warfare centers and various headquarters activities in Washington, D.C.

Magnetohydrodynamic propulsion systems for submarines offer several significant advantages over conventional propeller propulsion systems. These advantages include the potential for greater stealth characteristics, increased maneuverability, enhanced survivability, elimination of cavitation limits, greater payload capability, and the addition of a significant emergency propulsion system. These advantages can be obtained with a magnetohydrodynamic propulsion system that is neutrally bouyant and can operate with the existing submarine propulsion system power plant. A thorough investigation of magnetohydrodynamic propulsion systems for submarine applications has been completed. During the investigation, a number of geometric configurations were examined. Each of these configurations and mounting concepts was optimized for maximum performance for a generic attack class submarine. The optimization considered each thruster individually by determining the optimum operating characteristics for each one and accepting only those thrusters that result in a neutrally buoyant propulsion system. The results of this detailed optimization study show that the segmented, annular thruster is the concept with the highest performance levels and greatest efficiency and offers the greatest potential for a practical magnetohydrodynamic propulsion system for attack class submarines. The optimization study results were used to develop a specific point design for a segmented, annular magnetohydrodynamic thruster for an attack class submarine. The design point case has shown that this thruster may be able to provide the necessary thrust to propel an attack class submarine at the required velocity with the potential for a substantial acoustic signature reduction within the constraints of the existing submarine power plant and the maintenance of neutral buoyancy. This innovative magnetohydrodynamic propulsion system offers an approach for submarine propulsion that can be an important contributio

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3期96卷 25-38页

作者： SIMS, PJ EDWARDS, JR DICKEY, RL SHULL, HS Philip J. Sims:graduated from Webb Institute in 1971 and went to work for the Advance Design Branch of the Naval Ship Engineering Center. He was part of the FFG-7 design team in 1972. The 1973–75 years were spent developing automated early-stage aircraft carrier design procedures and performing carrier design trade-off work in support of the CVV design. He returned to school in 1976 for a masters at M.I. T. The 1977–80 period was spent updating the Navy's destroyer-cruiser early-stage design procedures and performing studies for the CGN-42 reserve FFX and DDX (later DDG 51) projects. Also during this period he was team leader on concept formulation (CONFORM) studies of new ships such as a heavy combatant and a low detectability ship. From 1981 to early 1983 Mr. Sims was Design Integration Manager for the BB-62 and Ship Design Manager for the BB-61 and CA-134. He is presently principal naval architect for the FFX study and also works on the NA TO frigate effort. James F. Edwards Sr:.is the Technical Director Ship Analytics Inc. Washington D.C. Operations and was the Ship Design Manager for the battleship USSNew Jerseyprior to his departure from NAVSEA in August 1983. He joined the U.S. Navy Reserves in 1954 and served on active duty from 1957 to 1960. From 1961 to 1963 he worked for McLaughlin Research Corporation as a section head in the drafting department. From 1963 to 1966 he worked for the Vitro Corporation of America in the Terrier (surface missile systems) Department. In 1966 he participated in the contract design of the first shipboard integrated digital ASW Command and Control system while working for the Stanwick Corporation. In 1967 Mr. Edwards accepted a position at NAVSHIPS in the Combat System Integration Division. In 1974 he transferred to what is currently NAVSEA's Hull Design Division. In 1980 Mr. Edwards was designated as the Battleship and Heavy Cruiser General Arrangements Task Leader and subsequently served as the Hull Task Group Manager the Ship Configuration Control Manager and fina

In reactivating the battleship New Jersey , the Navy faced three major problems. The baseline data on the ship was not readily available or reliable, a new generation cruise missile armament was proposed, and the ship delivery schedule was very tight. After doing a feasibility study, system design engineers were taken onboard the mothballed ship to resolve the design problems. Being on the ship allowed an intensive effort and immediate reference to the actual ship configuration. The tools used to control this effort were a ship check plan, a ship check form and the master arrangement drawing. Simultaneously with the design effort, a repair scoping effort was conducted. The design evolution and solutions to the major problems are described. The results of the New Jersey effort are shown with sample documentation, the ship characteristics and the downstream design effort. The Iowa was the next ship to be modernized. The top level requirements were the same as New Jersey's but new problems were encountered. More options were investigated which diverted attention from the basic effort. A fundamental difference was the Iowa had not had a 1968 reactivation as the New Jersey had, so items that were repair and reactivation on the New Jersey in 1968 had to be part of the Iowa modernization. A major influence on the Iowa design process was that a complete set of specifications for a private yard bid had to be developed. The next effort was to install the same New Jersey modernization payload on a Des Moines class heavy cruiser. Heavy cruisers are large ships but significantly smaller than battleships and much closer to their naval architectural limits of weight and center of gravity. They have much less topside area than the battleships, and the new payload was very topside space consuming. The cruisers are also much more restricted in internal volume. Two feasibility studies were conducted. One resolved volume problems but approached the weight and center of gravity limits.

This paper descirbes how ship weights are estimated. Detail is presented concerning relationships between existing weight data and the characteristics of a new design as it develops from completion of feasibility design through contract design. Margin requirements are also discussed. The weight estimating ratios and factors presented, while not directly associated with a specific ship type, cover the weight classification groups one would use in the design of a surface combatant. The purpose of this paper is to present the fundamentals of weight estimating to the ship design community. With this knowledge, ship design engineers and managers should be able to personally identify with the important parts they all play in creation of a credible weight estimate.
