Nachteile des Standes der TechnikDisadvantages of the prior art

Tretboote mit Tragflächen erfüllen die Funktion des verminderten Fahrwiderstandes durch Herausheben des Bootskörpers aus dem Wasser nur kurzzeitig, weil die benötigte Energie von Menschenkraft nur in sehr begrenzter Zeit zur Verfügung steht. Die bisher angewendeten Bauweisen führen im Endergebnis zu sehr schweren Booten, das gilt auch für Solarkanus, die aus diesem Grunde mit sehr starken und infolgedessen sehr schweren Pufferbatterien ausgerüstet werden müssen.Pedal boats with wings fulfill the function of reduced driving resistance Lifting the hull out of the water only for a short time because the energy required by Human power is only available in a very limited time. The previously used In the end, construction methods lead to very heavy boats, which also applies to solar canoes for this reason with very strong and consequently very heavy backup batteries must be equipped.

Aufgabe der ErfindungObject of the invention

Das Tragflächenboot soll durch konsequente Leichtbauweise (Sandwich-Waben-Bauweise) und durch den Anbau von oberflächendurchstoßenden Tragflächen eigenstabil mit einem relativ schwachen Solar-Elektroantrieb (Pufferbatterien mit verhältnismäßig kleinem Gewicht) ausgerüstet, über 1 bis 2 Stunden mit geringem Fahrwiderstand nur mit getauchten Tragflächen fahren.The hydrofoil should consist of lightweight construction (sandwich honeycomb construction) and inherently stable with the addition of surface penetrating wings relatively weak solar electric drive (buffer batteries with a relatively small weight) equipped, over 1 to 2 hours with low driving resistance only with submerged wings drive.

Lösung der AufgabeSolution of the task

Die extreme Leichtbauweise wird erreicht, indem handgefertigte ungetränkte Waben aus Zeitungspapier als Trägermaterial für die GFK-Sandwichbauweise verwendet werden. Das Boot kann 1 bis 2 Stunden mit geringem Fahrwiderstand nur mit getauchten Tragflächen fahren, da das Boot ein sehr geringes Gewicht (ohne Einbauten nur 1 kg) aufweist und der Solarantrieb daher ausreicht, um das Boot aus dem Wasser zu heben.The extreme lightweight construction is achieved by using handmade soaked honeycombs Newsprint can be used as a carrier material for the GRP sandwich construction. The boat can last 1 to 2 hours with low driving resistance only with submerged wings drive because the boat has a very low weight (without fittings only 1 kg) and the Solar drive is therefore sufficient to lift the boat out of the water.

Vorteile der ErfindungAdvantages of the invention

Das Solartragflächenboot in Wabenleichtbauweise hat folgende Vorteile:The lightweight solar hydrofoil boat has the following advantages:

  • - Das extrem geringe Gewicht aufgrund des Papiermaterials- The extremely low weight due to the paper material
  • - Die oberflächendurchstoßenden Tragflächen, die im Gegensatz zu vollgetauchten Tragflächen die Lage des Bootes im Wasser stabilisieren.- The surface piercing wings, in contrast to fully submerged wings stabilize the position of the boat in the water.
  • - Der umweltfreundliche Solar-Antrieb- The environmentally friendly solar drive
  • - gute Wärmedämmung der Bootswandung aufgrund der Sandwichbauweise.- Good insulation of the boat wall due to the sandwich construction.
  • - Das Schiff ist praktisch unsinkbar, da die Wandung leichter als Wasser ist.- The ship is practically unsinkable because the wall is lighter than water.
  • - geräuscharme Fahrweise- low-noise driving style
Beschreibung von Ausführungsbeispielen der Erfindung (Skizze)Description of exemplary embodiments of the invention (sketch)

Die Computer-Skizze zeigt:The computer sketch shows:

  • - das Solarpanel, das mit dem Solarladeregler im inneren des Bootes verbunden ist. (Dieser gibt die Energie weiter an die Akkus)- the solar panel, which is connected to the solar charge controller inside the boat. (This gives the energy to the batteries)
  • - die Ruderbetätigung, die mit einem Empfänger im inneren des Bootes verbunden und somit nach rechts und links beweglich ist.- The rudder control, which is connected to a receiver inside the boat and thus is movable to the right and left.
  • - den Propeller, der mit maximal 10.000 U/min das Boot antreibt.- The propeller that drives the boat at a maximum of 10,000 rpm.
  • - die Ruder, die das Boot "lenkbar" machen- the oars that make the boat "steerable"
  • - die biegsame Welle, die mit dem Motor verbunden ist.- the flexible shaft connected to the motor.
  • - die Bugtragfläche, die aufgrund der V-Form Rückstellkräfte erzeugt. V-Form deshalb, weil bei großer Geschwindigkeit eine kleine mit Wasser benetzte Fläche (die untere Tragflächenspitze) ausreicht und bei geringerer Geschwindigkeit eine größere Fläche benötigt wird.- The front wing, which generates restoring forces due to the V-shape. V shape because at high speed a small area wetted with water (the lower one  Wing tip) is sufficient and requires a larger area at lower speeds becomes.
  • - die Hecktragfläche, die aufgrund ihrer waagerechten Form und den seitlich angesetzten Ohren den Auftrieb für das Heck des Bootes liefert und die Lage des Bootes im Wasser stabilisiert.- The rear wing, which due to its horizontal shape and the side Ears provides the lift for the stern of the boat and the location of the boat in the water stabilized.
