Abstract
Description
Die Erfindung betrifft ein System zur Verringerung des Wasserwiderstands von Schiffen und zur Erhöhung der Gleitfähigkeit von Booten. Der Name des Systems L-M-Järn-System setzt sich aus den Begriffen Luft, Meer und Järn für Eisen zusammen.The The invention relates to a system for reducing water resistance of ships and to raise the lubricity from boats. The name of the system L-M-Järn system consists of the terms Air, sea and Järn for iron together.
Die Erfindung wird nachfolgend anhand von zwei in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Es zeigenThe Invention will be described below with reference to two in the drawing embodiments explained in more detail. It demonstrate
Mit dem nunmehr vorgestellten System soll
- 1. bei Schiffen mit Tiefgang (Frachtschiffe) der Wasserwiderstand abgebaut und
- 2. bei Booten die Gleitfähigkeit erhöht werden.
- 1. in ships with draft (cargo ships) the water resistance degraded and
- 2. In boats, the lubricity can be increased.
zu 1. Schiffe mit Tiefgang (
Das
System für
diesen Schiffstyp besteht aus einem Profil aus offenen, geschlitzten
Röhren

Die
Funktion des Systems:
Das vom Schiffsrumpf (Bugbereich) verdrängte Wasser
gelangt während
der Schiffsbewegung mit Hilfe der Leitprofile
The water displaced by the hull (bow area) arrives during the ship movement with the help of the guiding profiles
Die
Luftdüsen
Die
Profilreinigung lässt
sich bequem über die
Längsschlitzung
Ein nützlicher Nebeneffekt für die Natur ist, dass die befahrenen Wasserwege bis zu einer Tiefe von 10,00 m und mehr gut durchlüftet werden.One more useful Side effect for the nature is that the navigated waterways to a depth of 10.00 m and more well ventilated become.
Die
Bemessung der gesamt erforderlichen Profilquerschnittsfläche setzt
sich aus den Faktoren
der Schiffsgröße mit Breite und Tiefgang
sowie
aus der angestrebten Geschwindigkeit zusammen.The dimensioning of the total required profile cross-section area is based on the factors
the ship size with latitude and draft as well
from the desired speed together.
Durch die geordnete „Wasserableitung” wird bei gleich bleibender Motorleistung eine höhere Fahrgeschwindigkeit erzielt. Und bei konstanter Geschwindigkeit ist ein geringerer Leistungsaufwand erforderlich. Die geschätzten Einsparungen an Kraftstoff können im Idealfall 30% und mehr betragen.By the ordered "water drainage" is added constant engine power achieved a higher driving speed. And at constant speed is a lesser effort required. The estimated Savings on fuel can ideally 30% and more.
zu 2. Erhöhung der Gleitfähigkeit
von Booten (
Bei den wassergleitenden Booten muss die Vorgehensweise für das System eine andere sein, doch auch hier sollen Wasser und Luft genutzt werden. Das ordnungsgemäße Zusammenwirken von Wasser und Luft muss hier in einem geänderten Profil erfolgen. Das halbkreisförmige, nach unten offene Rohrsystem wird beidseitig am Bootsrumpf befestigt. Die Länge des Rohrsystems darf nicht mehr als 4/5 der Bootslänge betragen.For water-skimming boats, the approach to the system must be different, but water and air should also be used here. The proper interaction of water and air must be done here in a modified profile. The semicircular, downwardly open pipe system is attached to both sides of the boat hull. The length of the pipe system must not exceed 4/5 the boat length.
Die
ideale Längsneigung
des Bootes bei der Fahrt muss sein, dass ungefähr 1/3 der vorderen Rohrquerschnittsfläche aus
dem Wasser ragt. Ein Bugruder mit verstellbarem Tiefenruder
Bei
zunehmender Geschwindigkeit vereinigen sich dann im System, die
von vorne einströmende
Luft und das vom Boot aufgewirbelte Wasser. Dieses Wasser-Luftgemisch
beschert dem Boot eine ideale Abfederung, so dass man von einer
stoßfreien Fahrt über das
Wasser sprechen kann. Bugruder mit dem verstellbaren Tiefenruder
