The structural design of a ship's section is a complicated, repetitive and time consuming task. With the advent of new technology, high speed computers have enabled the ship designer to accomplish in a matter of seconds what would formerly take days to accomplish by hand. The Structural Synthesis Design program (SSDP) is a N avy developed computer-aided design tool which is used to design (or to analyze) the longitudinal scantlings for a variety of ship cross sections, consisting of any practical combinations of decks, platforms, bulkheads and materials, i.e., various steel and aluminum alloys. The final hull section design will have the lowest practical weight for the chosen geometric configuration, structural arrangements, and imposed loadings. The scantling developed by the program will satisfy all U.S. N avy ship structural design criteria. An explanation of the objective and design elements of N avy ship structures is included. The rationale behind the SSDP design philosophy is developed along with the significant program capabilities. In an attempt to highlight the influence of automated design procedures on the current naval ship design process, the effect of the SSDP on the DDG 51 destroyer structural development is addressed.

FLUK, HThe authorgraduated from New York University in 1952 as an Aeronautical Engineer and entered the United States Air Force (USAF). He attended the USAF Institute of Technology for graduate Aerodynamics
and following that served three years as a Project Officer in the field of Special Weapons. Returning to civilian life in 1957 he joined Curtiss-Wright Corporation's Engine Division and shortly thereafter transferred to the company's Model 200 V/STOL Aircraft Program later to become the Tri-Service X-19. His responsibilities variously included Flight Loads and Controls Aerodynamic Research and publication of the X-19 Aircraft Technology. In 1966 he joined Boeing's VERTOL Division initially working in helicopter stability and then in downwash and autorotation characteristics. This was followed by research and development and long-range planning and then assignment to introduce new computer services to the Engineering Department. In 1975 he joined the Naval Air Engineering Center Lakehurst N.J. to provide technology in horizontal and vertical engine jet flows and at the present time is Manager for Systems Studies in the Advanced Systems Office where he works with the Aircraft and Ship Communities to enhance military effectiveness at sea.

A weapons system has been configured specifically to counter (or preempt) the long-range standoff missile threat. Rationale for this system starts with a discussion of cost and weight, and shows why modern multi-mission systems have become intolerably expensive. Questions are raised regarding the advantages and disadvantages of building future naval aviation forces solely around the Aircraft Carrier Battle Group. The application of a few small modern ships, forming a future Battle Force, holds promise for large economies. Likewise, some accepted views regarding CTOL (Conventional Take Off & Laundry) and V/STOL (Vertical Short Take Off & Launding) aircraft are revisted in terms of their relative costs. A weapons system is proposed which, at one-fourth the weight of an Aircraft Carrier Battle Group, may be produced and operated for one-third the cost.

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.

A description will be given of a process consisting of two connected vertical stand-pipes. This physical process is rather simple in the details of its construction, but the relationship between the flows into and out of the standpipes and the levels is nonlinear and complicated. A nonlinear mathematical model will be derived to describe the dynamical behaviour of this system. A control structure with nonlinear multi loop feedforward and linear single loop feedback control will be analyzed and discussed. Simulation and implementation with an experimental laboratory set-up are used to illustrate and demonstrate the behaviour of process with the proposed control structure.
