This paper presents an integrated approach to computer-Aided Ship Design for U.S. Navy preliminary and contract design. An integrated Hull Design System (HDS), currently under development by the Hull Group of the Naval Sea Systems Command (NAVSEA 32). is the vehicle for the discussion. This paper is directed toward practicing ship design professionals and the managers of the ship design process. Primary emphasis of this paper, and of the development effort currently under way, is on aiding ship design professionals in their work. Focus is on integration and management control of the extremely complex set of processes which make up naval ship design. The terminology of the Ship Designer and Design Manager is used. The reader needs no familiarity with the technologies of computer science.

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.

Director of Advanced Programs and IRBD. Ingalls Shipbuilding Division Litton Industries Pascagoula Miss. has been an active member of ASNE since 1970. a frequent contributor to the Naval Engineers Journal and a participant at ASNE Day meetings as both an Author and a Discusser. He is an Associate Fellow of the American Institute of Aeronautics has twenty-three years experience in the field of Naval Engineering and is a graduate of the California Institute of Technology from which he received his B.S. degree (1950) and his M.S. degree (1952). both in Mechanical Engineering. and his Ph.D. degree (1954) in Mechanical Engineering and Mathematics. Mr. H. Richard Stiles graduated from the U.S. Naval Academy in 1965. Prior to leaving the naval service in 1970
he was designated as a Naval Aviator and authored two Patents one for an aircraft optical glide slope reference system and the second for an intercommunications system for air traffic control. As an author he has had technical papers published by SNAME — “Planning Hull Structure” — and by the Offshore Technology Conference — “A Fourth Generation Crewboat.” At the present time he serves as an Engineering Specialist for the Hull Technical Department at Ingalls Shipbuilding Division. Mr. Stephen P.K. Ho is also with Ingalls Shipbuilding Division where
since 1970 he has worked on various phases of naval engineering and advanced studies. He received both his B.S. and M.S. degrees in Naval Architecture and Marine Engineering from the University of Michigan in 1958 and 1959 respectively. and prior to joining Ingalls Shipbuilding Division also worked with other Marine Firms in ship design particularly in computer applications to Preliminary Design the Construction Process and the Management Information System. Besides ASNE which he joined in January 1980. he is a member of SNAME.

Lower Fleet operating costs and independence from foreign fossil fuel resources are the goals of energy conservation efforts for Navy surface ship. This paper describes an evaluation of a wide variety of energy conservation approaches. A standard 20-knot, 300-hour Destroyer mission is established so that all of the approaches can be compared on a total fuel required basis. The approaches studied include use of aluminum hull construction; light weight machinery; trail-shaft or cross-connect operation for twin screw ships; improved performance propulsors; advanced power plant types, such as COGAS or cruise engines; use of energy storage techniques to improve ship service generator performance; electrical load reductions; improved performance ship service generators; hull drag reductions; crew size reductions; design margin reduction; reduced performance requirement (such as top speed); and habitability standard reductions. The overall results can be effected by reductions in range requirements as well. Mission duration was held constant at 45 days throughout the study. The results of the study indicate that the combination of these various possible improvements may reduce the fuel used to be as low as one-third of the current levels. Weight reductions are very effective for achieving significant fuel savings.
