Die Erfindung wird nachfolgend anhand von einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert. Es zeigenThe invention will be explained in more detail with reference to an embodiment shown in the drawing. Show it
Mit der nunmehr vorgestellten Vorrichtung soll bei Schiffen mit Tiefgang (Frachtschiffe) der Wasserwiderstand abgebaut werden.With the now presented device, the water resistance is to be reduced in ships with draft (cargo ships).
Schiffe mit Tiefgang (Fig. 1 bis Fig. 3)Ships with draft (Fig. 1 to Fig. 3)
Die Vorrichtung für diesen Schiffstyp besteht aus einem Profil aus offenen, geschlitzten Röhren
Das Profil der einzelnen Röhren
Die Ein- und Auslauföffnungen der Vorrichtung können mit Klappen
Die Funktion der Vorrichtung:The function of the device:
Das vom Schiffsrumpf (Bugbereich) verdrängte Wasser gelangt während der Schiffsbewegung mit Hilfe der Leitprofile
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.A useful side effect for nature is that well-traveled waterways are well ventilated to a depth of 10.00 meters and more.
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.The orderly "water drainage" achieves a higher driving speed while maintaining the same engine output. And at constant speed, less power is required. The estimated fuel savings can ideally be 30% or more.
