Definitions
- the invention relates to a ship or boat hull according to the preamble of claim 1.
- the invention is based on the object of designing a hull so that it dips relatively softly into the water with high dimensional stability against heeling, even at sea, and to reduce the resistance to an absolute minimum the displacement performance, ie the displacement work while driving, over almost the entire hull length is distributed in order to largely avoid the formation of resistance-increasing negative pressure zones (suction zones) in the rear area and thereby to reduce to a minimum the sag of the tail, which is the result of excessive displacement.
- Fig. 1 shows a wide fuselage (1) with a slim projection (2), the lower edge (4) from the point of highest displacement at the same depth further to the rear, while its side surfaces (3) converge in a line at the back.
- Fig. 3 shows an embodiment of a fuselage (1) with a slim projection (2), the side lines (3) diverge further apart from the point of greatest displacement to the rear, while the lower edge (4) runs backwards upwards and in the fuselage (1) .
- the fuselage will lift out a bit more at the front and sag slightly at the back, so that there will no longer be any negative pressure in the area of the frame (j ⁇ ) to the frame.
- This fuselage carries much more at the back than (1) and is particularly suitable for heeling. Then he lies in the water with a sliding surface.
- the lines of the frames 3), (Z) and ($) are shown.
- the loss of cross-section (5a) of the lower, slim projection (2) between frame (5) and) can be seen, while in the area of the upper fuselage part (1) there is an increase in cross-section (5b).
- the cross-sectional loss (4a) can be seen in the lower area between the frame (4) and ( ⁇ ), while another cross-sectional gain (4b) can be seen at the top.
- the lower projection (2) displaces the water with extremely little power due to its pointed shape and its associated extremely small volume increase in the longitudinal direction. Most of the water flows along the slim hull and experiences only low lateral acceleration forces or transverse speeds, so that in principle only a kind of pre-acceleration takes place. The water pre-accelerated in this way with relatively little effort makes it easier for the part that is becoming increasingly voluminous to do the displacement work due to a lower back pressure, which also reduces the actual frictional forces on the surface.
- the displacement of the upper part of the hull (1) which begins approximately from frame @ and increases towards the rear, not only causes the displacement line to extend almost over the entire length of the ship, but at the same time also prevents the suction on the side walls, which increases with increasing speed ( 3) of the lower projection (2). Because the water is also in the back
- FIG. 3 shows an example in which the inevitable loss of volume of the slim projection (2) is brought about by the lower edge (4) running upwards.
- the slender protrusion is widened at the same time as it continues to the rear at the transition to the upper part of the fuselage (1) until, in its entirety, it merges harmoniously into the upper fuselage.
- FIG. 4 it is shown in FIG. 4 how the area or volume shrinkage of the lower projection (2) is largely compensated or superimposed by increasing the volume of the upper fuselage part. This can be seen again from the hatched areas (4a) and (4b) as from the areas (5a) and (5b).
- the crack of the frame is shown here.
