Definitions
- the present invention has the object of obviating above mentioned disadvantages.
- the present invention is characterised in that the bottom part of the hull is divided into compartments; the compartments being open at the bottom in such manner as to give rise to the formation of at least four elementary captured air bubbles.
- the compartments are bounded by three longitudinal partitions, one of which is in the axis of symmetry of the hull, and by three transversal partitions.
- the bottom edges of all the partitions are preferably in a single plane which is substantially horizontal at rest.
- the above briefly described structure results in division of the bubble into four elementary bubbles and provides stability because in the case of a difference in level the bubbles of the portions which are immersed to a greater extent will be at a higher pressure than the bubbles of the portions which have emerged to a greater extent. Accordingly, the difference in pressure between the respective bubbles supplies the lifting couple.
- the front walls of the transversal partitions are convex cylindrical in shape.
- the axes of the cylinders are perpendicular to the plane of symmetry of the hull in the case of the front walls of the rearmost partitions, while the axis of the cylinders of the front walls of the front partition form an acute angle with said plane of symmetry.
- the front transversal partition taken as a whole and viewed in plan, has a V-shaped form, the point of the V forming the stem of the hull.
- the overall shape of the bow of the vessel viewed in plan will preferably be that of a W, the outer side branches of the W forming lateral aprons having the effect of containing the two branches of the central stem wave and of reducing, if not eliminating, their drag effect.
- Each bubble is preferably supplied continuously with air by an independent blower or, as an alternative, the bubbles are fed by a common blower delivering into a number of pipes equal to the number of compartments.
- each pipe has a loss of head suitably calculated to make the deliveries uniform, since otherwise they would be disturbed by the movements of the hull.
- the pressurised air is preferably introduced into each compartment through the bottom portion, tangentially to the bottom limit plane.
- FIG. 1 illustrates the hull, which is assumed to be in section through a horizontal plane immediately above the flat bottom and viewed from below, with nevertheless a slight effect of perspective.
- the hull may have any shape and structure in the invisible portion beyond the sectional plane.
- This flat bottom 1 constitutes on its lower side the upper plane delimiting the bubbles.
- FIG. 2 is a sectional side elevation view of a portion of the hull shown in FIG. 1, FIG. 2 depicting the preferred method of furnishing pressurised air to the bubbledefining hull compartments.
- the invention relates to the arrangement of the portion beneath said flat bottom.
- Two longitudinal partitions 6 and 7 bound the compartments laterally.
- the outer walls are extensions of the hull and the inner walls are flat and inclined towards the interior of the compartments.
- the middle partition 8 the edge of which is in a plane of symmetry of the hull, likewise has flat walls inclined towards the interior of the compartments.
- the transversal partitions have convex front walls 12 in the form of a cylinder having a horizontal axis perpendicular to the plane of symmetry of the hull. Along the edges 9 and these walls adjoin the bottom limit plane of the bubble.
- the rear walls 13 of these partitions are flat and vertical or inclined towards the interior of the compartments.
- the bow of the vessel has here the general shape of a W, the bottom edges of the outer branches of the W being designated by 14 and 15 and the bottom edges of the branches of the central V, defined by the forward transversal partition, being designated by 16 and 17.
- the walls 18 to 21 are convex cylindrical, the axes of the cylinders forming acute angles with the plane of symmetry of the hull. Their faces are joined along the edges 14 to 17 tangentially to the bottom limit plane of the bubble.
- the faces 18 and 20 are joined together, and the faces 19 and 21 are joined together, by cylindrical surfaces 22 and 23, the axis of the cylinders being perpendicular to the aforesaid plane of symmetry.
- the rear faces are preferably vertical.
- air will preferably be supplied to the compartments by means of nan-ow slots disposed along the rear faces of the transversal walls, preferably near the edge situated in the bottom limit plane of the bubbles.
- a hull for a vessel characterised in that the bottom portion of the hull is divided into a plurality of compartments, the compartments being opened at the bottom and giving rise to the formation of at least four elementary air bubbles, said compartments being defined in part by three rigid longitudinal partitions, one of said longitudinal partitions being aligned with the axis of symmetry of the hull, said compartments being further defined by at least three rigid transversal partitions, the bottom edges of all of said partitions lying in a single plane which is substantially horizontal with the vessel at rest.
- a bubble hull according to claim 1 characterised in that the front walls of the transversal partitions are of convex cylindrical shape, the axis of the cylinders being perpendicular to the plant of symmetry of the hull in the case of the front walls of the rearmost partitions, while the axis of the cylinders of the front walls of the front partition form an acute angle with said plane of symmetry.
- a bubble hull according to claim 2 characterised in that the front walls are terminated horizontally at their vanishing point and tangentially to the bottom limit plane of the bubble.
- a bubble hull according to claim 1 characterised in that the front transversal partition, as a whole and viewed in plan, has a V-shaped form, the point of the V forming the stem of the hull.
- a bubble hull according to claim 4 characterised in that the shape of the forward end of the hull including said front partition will be that of a W.
- a bubble hull according to claim 1 characterised in that the pressurised air is introduced into each compartment through the bottom portion and tangentially to the bottom limit plane.
