DE19626047C2 - Sliding hull for boats, ships and other floating bodies - Google Patents

Description

The invention relates to a hull for boats, ships and Floats such as jet skis or skids for seaplanes according to the preamble of claim 1.

It is known that low displacement and low friction and thus economical boat hulls a horizontally flat and if possible must have a small sliding surface. On the other hand, what should be rough strong hulls have a keel as deep as possible and be shaped to the point V, so that a soft immersion in the Waves is possible.

A compromise is made with conventional boat hulls between the immersion ability on the one hand and the sliding ability on the other hand, by making the V more or less pointed designed. In any case, a significant part of the Driving energy converted into displacement of water.

From US 4,528,931 a boat is also known in which the fuselage, viewed from below, opens in the direction of travel th V-shaped sliding surfaces, each in the V the previous one is stuck and the sliding surfaces of neighboring V's by ver or perpendicular to the water surface running surfaces are interconnected so that each cross cut a staircase rising to the left and right, has a symmetrical profile. The sliding surfaces end in under different heights from the keel. Hereby should be achieved be that the boat is only on the deeper sliding surfaces and thus a low friction wi the status. The disadvantage of this boat is that its Principle only works with calm water.

Starting from the boat according to US 4,528,931, the Erfin lies tion based on the task of designing the sliding surfaces so that resistance reduction even in harsher weather conditions tion is achieved.

This object is achieved by those listed in the claim Features resolved.

Since the sliding surfaces are bent upwards towards the bow, Driving energy converted into buoyancy instead of water displacement.

The water demolition caused by the construction of the hull edges reduce friction with the water. Those edges who through the ends of the sliding surfaces and the ends of the ones on it vertically or almost perpendicular connecting surfaces of the adjacent sliding surfaces. To water separation edges they become, since the respective rear sliding surface more is curved above than the one in front of it.

Spray forms on the bow and behind the water separation edges under the sliding surfaces to reduce water friction leads.

By optimizing the bending strength of the sliding surfaces while driving direction, the exact angle at the water separation edges, the Width of the individual sliding surfaces at the different points, the height of the connecting surfaces between adjacent sliding surfaces Chen and the number and angle of the "stuck" V′s according to use, size, weight, size machine performance, the form specifications etc. Can the compromise between gliding and immersion of the fuselage essential Make it more economical than conventional hulls.

An embodiment of the invention is shown in the drawing provided and explained in more detail below.  

Show it:

Fig. 1 is a side view of the fuselage

Fig. 2 is a bottom view of the fuselage of Fig. 1

Fig. 3 section 1, 2 and rear view.

The curved lines in FIG. 1 represent the sliding surfaces 1 , which extend perpendicular to the plane of the drawing. The vertical fuselage surfaces 3 can be seen between these lines.

Fig. 2 shows the sliding surfaces 1 and the vertical rump surfaces 3 in a view from below. Here you can see that the vertical hull surfaces form 3 tear-off edges.

Fig. 3 shows the sliding surfaces 1 and the flat keel surface 2 in different cross sections.

Claims (1)

Sliding hull for boats, ships and floating bodies such as jet skis or carrying runners for seaplanes, the hull, viewed from below, consists of a V-shaped sliding surface opened in the direction of travel, each of which is in the V of the previous one and the sliding surfaces of neighboring V ′ s are connected by perpendicular or almost perpendicular surfaces to the water surface with each other, so that each cross-section has a stair-like, symmetrical profile rising to the left and right, characterized in that the sliding surfaces ( 1 ) from a flat keel surface ( 2 ) in the direction Bow are gradually bent upwards.
