SNAME N.Y. Metropolitan Section Hears Technical Paper On 'New Approach To The Ship Hull Characteristics Problem'
The New York Metropolitan Section of The Society of Naval Architects and Marine Engineers met on January 15, 1974, at the Seamen's 'Church Institute in New York City.
After a social hour and dinner, the technical session was held at which a paper was presented entitled "A New Approach to the Ship Hull Characteristics Problem," by D. Hoffman and T. Zielinski of the Webb Institute of Naval Architecture.
In the paper, conformal mapping techniques are used as a mathematical means of presenting the two-dimensional ship section iby means of an array of approximately 10 elements.
The geometric properties of any transverse section are determined in an explicit form rather than by numerical approximation.
These arbitrarily spaced transverse sections are integrated longitudinally to give specific values for tanks or damaged compartments, as well as the general ship characteristics for the case of level, trim or any other mathematically defined waterline profile such as a sinusoidal or trochoidal wave.
This form of ship geometry input is particularly suited for computer applications, due to its compact storage requirements. It is also identical to the input used for ship dynamics calculations to determine motions, loads, vibrations, etc.
Examples showing applications of this approach in both ship design and onboard hardware .manipulations are given.
Society president Phillip Eisenberg was present at this meeting and addressed the members of the Section on Society programs and other matters of interest to the membership.
