Abstract
Description
Die Erfindung betrifft den hydrodynamisch - auf der Basis aerodynamischer Erkenntnisse - verbesserten SPALTENKIEL, einen festen Kiel mit Ballast, der an Segelyachten jeder Größe angebaut werden kann.The invention relates to the hydrodynamic - based aerodynamic knowledge - improved SPALTENKIEL, a fixed keel with ballast, which can be used on sailing yachts of any size can be grown.
In der Patentanmeldung
P 43 44 740.6-22,
PCT/DE 93/01243
sind der neuartige Spaltenkiel und der konventionelle Kiel
sowie der Flügelkiel gegenübergestellt, um die Wirkungsweise
des Spaltenkiels zu erläutern.In patent application P 43 44 740.6-22, PCT / DE 93/01243
The new split keel and the conventional keel as well as the wing keel are compared to explain the mode of operation of the split keel.
Das bisherige Ergebnis:
Infolge der Elimination der KARMAN′schen Wirbelschleppe wird
die negative Beeinflussung des Ruders aufgehoben; durch den
Zuwachs des "VIRTUELLEN BALLASTES" mit zunehmender Fahrt und
Krängung der Segelyacht wird sie steifer - beides zusammen
bewirkt eine Verringerung der Abtrift, damit eine Verkürzung
des Leerweges, gleichbedeutend einem Geschwindigkeitsgewinn!The result so far:
As a result of the elimination of the KARMAN vortex, the negative influence on the rudder is removed; with the increase of the "VIRTUAL BALLAST" with increasing cruising and heeling of the sailing yacht it becomes stiffer - both together reduce the drift, thus shortening the free travel, which means a gain in speed!
Der andere Anteil an der gesamten Erhöhung des Geschwindigkeits potentials der Yacht nach dem Einbau des "SPALTENKIELS" resultiert aus dem Düseneffekt infolge der Gestaltung des neuartigen Kiels; in der Düse wird der Strom der Wasserfäden geradlinig auf dem kürzesten Wege vom Bug zum Heck geleitet und erfährt durch die Grenzschicht-Absaugung - von den Außenflächen der Spaltenkielplatten in den Düsenstrom hinein eine weitere Beschleunigung. The other part of the total increase in speed potential of the yacht after installing the "SPALTENKIELS" results from the nozzle effect due to the design of the novel keel; in the nozzle is the stream of water threads straight from the bow to the stern and experiences through the boundary layer suction - from the Outer surfaces of the slotted keel plates into the jet stream another acceleration.
Durch drei weitere Verbesserungen, die Gegenstand der Anmeldung diese Zusatzpatentes sind, wird eine weitere Steigerung der Geschwindigkeit der Yacht als eine erstrangige Maxime der Yachtkonstruktion erreicht.By three further improvements, the subject of the application these additional patents will further increase the Speed of the yacht as a top priority of the Yacht construction achieved.
- 1. Die Spaltenkielplatten erhalten ein Profil, wie es aus Versuchen und der Konstruktion von Tragflügeln bekannt ist: eine stärkere, gut abgerundete Vorderkante an der Eintrittsöffnung der Düse, die Innenflächen der Spaltenkiel platten haben kein stromlinienförmiges Profil mehr, sondern sondern jetzt eine konkave Wölbung von vorn nach achtern, im Heckbereich sind die Kielplatten fein ausgezogen und haben eine scharfe Abschlußkante.1. The slatted keel panels get a profile like this Trying and designing wings known is: a stronger, well rounded front edge on the Inlet opening of the nozzle, the inner surfaces of the column keel panels no longer have a streamlined profile, but but now a concave curvature from front to aft, in the stern area the keel plates are finely drawn out and have a sharp end edge.
In Modellversuchen sollte getestet werden, ob eine durchgehende gerade Kante weniger Störungen bringt als ein unterbrochener Abschluß, wie er bei den Hinterkanten der Vogelflügel zu beobachten ist!Model tests should test whether a continuous straight edge brings less interference as an interrupted degree, as in the The trailing edges of the bird's wings can be observed!
- 2. Die Spalten in den Spaltenkielplatten werden auf maximal zwei reduziert; die Spalten beginnen im Bereich des höchsten Wasserdrucks unten vorn und führen schräg nach hinten oben.2. The columns in the column keel plates are at maximum two reduced; the columns begin in the area of the highest Water pressure below the front and lead obliquely backwards up.
Anzahl und optimaler Verlauf der Spalten sind in Modellversuchen zu beobachten und nach Vergleichs messungen festzulegen.The number and optimal course of the columns are in Observe model tests and after comparison determine measurements.
- 3. Der Ballast wird als eine dicke Blei- oder Stahlplatte zwischen den untersten Enden der Kielplatten eingebaut.3. The ballast is called a thick lead or steel plate installed between the lowest ends of the keel plates.
Die Wölbung der Ballastoberseite in der Düse ist konvex, umThe curvature of the ballast top in the nozzle is convex to
- 3.1 zur Beschleunigung des Düsenstromes beizutragen und3.1 contribute to the acceleration of the jet stream and
- 3.2 ein Art planer Auflagerfläche zu schaffen, wenn die Yacht ins Winterlager geht oder draußen trockenfallen soll.3.2 to create a kind of flat support surface when the yacht goes to winter storage or is supposed to dry out outdoors.
Die endgültige Gestaltung des Ballastes, auch in Bezug auf die optimale Wirkung des "VIRTUELLEN BALLASTES" sollte in eigenen Modellversuchen besonderer Aufgabenstellung erfolgen.The final design of the ballast, also in Regarding the optimal effect of the "VIRTUAL BALLASTES "should be tested in its own model special task.
