Definitions

  • the present invention relates both to ships that sail on the water surface and to underwater ships.
  • the hull is to be given an optimal flow shape, this is generally spatially curved in substantial parts, that is to say without a flat development. This makes the production of the above-mentioned casting, pressing and overlay molds complex and expensive and forces steel and wooden boats to spatially deform the raw material.
  • the ship according to the invention is distinguished by the fact that its part of the hull immersed in the movement in the water has a level development that occurs as follows: two ellipses lying perpendicular to each other (including circles) intersect each other in such a way that that the periphery of one runs through the center of the other. This combination of ellipses is rolled on one level, the peripheries on the level denoting the contours of the outer surface of the spatial form that can be developed. This contour is with the means of mathematics and geometry can be determined, but are not shown here.
  • This spatial form is used as a whole for an underwater ship. If a surface watercraft is to be built, that part of the spatial shape that comes to rest under water when driving, usually at most half of it, is selected by a flat longitudinal section.
  • the hulls can be adapted over a wide range to the intended use and speed range. Size; There are advantages in mold making for the use of plastic materials as well as in the construction of flat plates, be they made of sheet metal, wooden veneers or the like.

Abstract

La coque du bateau présente un développement plan (25). Il est produit par deux ellipses (1, 2) placées dans deux plans perpendiculaires, possédant un demi-axe commun et déroulées sur un plan. Si ce développement (25) est placé autour de la paire d'ellipses génératrices (1, 2), ceci donne la coque d'un bateau sous-marin. Par une coupe longitudinale dans le plan par exemple de l'ellipse (12) ou dans un plan qui lui est parallèle, on obtient la coque d'un bateau se déplaçant à la surface de l'eau. Les organes de commande et de stabilisation comme le gouvernail, la quille et la dérive sont produits de la même façon et présentent également un développement plan. On forme ainsi le grand demi-axe d'une ellipse très allongée (21), qui est en même temps le petit demi-axe d'une seconde ellipse (22).
