Abstract:

A new method of solving problems related to the geometry of a ship hull is explained. This, the so-called parametric method, possesses great universality first, it enables one to construct ship design curves of water plane areas and curves of cross-sectional areas, in close mathematical agreement with the given geometric parameters, and, secondly, it enables one to obtain simple and sufficiently accurate quadrature formulas for computing areas, the coordinates of the centers of gravity and the moments of inertia of plane figures, bounded by ship-design curves for both constant and variable limits of integration. The parametric method greatly simplifies the work of the designer and computer, making possible a tenfold reduction in time. Moreover, in designing the lines of the hull using the parametric method there is no longer any essential need to determine the theoretical elements of the ships hull sections, since by virtue of this method they will closely correspond to the given geometric parameters. The theoretical elements for the hulls of ships designed using ordinary methods can be computed with high accuracy using the parametric method. Author
