Abstract
Description
Die Erfindung bezieht sich auf einen Kraftstofftank für Fahrzeuge, insbesondere Luftfahrzeuge, mit einem flexiblen Tanksack, der sich nach Füllung und Druckbeaufschlagung gegen die mit einer Schutzschicht versehenen Innenseiten der Tankwände anlegt.The invention relates to a fuel tank for vehicles, especially aircraft, with a flexible tank bag that extends after filling and pressurization against those with a Protective layer provided inside the tank walls.
Es ist bekannt, bei Fahrzeugen, insbesondere bei Luftfahrzeugen, im Tankinnenraum einen flexiblen Tanksack anzuordnen, der sich nach dem Füllen bzw. bei entsprechender Druckbeaufschlagung gegen die Innenseiten der Tankwände anlegt. Die Innenseiten der Tankwände werden darüber hinaus mit einer Schutzschicht versehen, um Korrosionen der Tankwände zu verhindern. Trotz dieser Schutzschichten lassen sich Korrosionen an den Tankwänden aber nicht verhindern, insbesondere dann nicht, wenn der Tankinhalt durch das Triebwerk aufgeheizt wird. Bei derartigen Luftfahrzeugen können im Tankraum Temperaturen bis zu 80° C bei hoher Feuchtigkeit entstehen. Diese Feuchtigkeit besteht meistens aus Wasser und möglicherweise aus Salzlösungen.It is known, in vehicles, in particular in aircraft, to arrange a flexible tank bag in the interior of the tank after filling or with appropriate pressurization against the inside of the tank walls. The inside of the Tank walls are also provided with a protective layer, to prevent corrosion of the tank walls. Despite this Protective layers prevent corrosion on the tank walls do not prevent, especially if the tank capacity is heated by the engine. In such aircraft can reach temperatures of up to 80 ° C at high temperatures in the tank room Moisture. This moisture usually consists of Water and possibly from saline solutions.
Da die flexiblen Tanksäcke unter Druck stehen, wird die zwischen den beschichteten Tankwänden und dem flexiblen Tanksack auf tretende Feuchtigkeit unter gleichzeitigem Auftreten kapillarischer Wirkungen an den Tankwänden festgehalten. Die Tankwände werden daher ständig dieser Feuchtigkeit im örtlichen Bereich ausgesetzt, welche nach relativ kurzer Zeit die Schutzschicht durchdringt und Korrosionen an den Tankwänden hervorruft. Since the flexible tank bags are under pressure, the between the coated tank walls and the flexible tank bag ingress of moisture with simultaneous occurrence of capillary Effects recorded on the tank walls. The tank walls are therefore constantly exposed to this moisture in the local area, which penetrates the protective layer after a relatively short time and Corrosion on the tank walls.
Der Erfindung liegt also die Aufgabe zugrunde, einen Kraftstofftank vorzusehen, dessen beschichtete Innenwände einen Langzeitkorrosi onsschutz gewähren. Diese Aufgabe ist gemäß der Erfindung dadurch gelöst, daß die mit der Schutzschicht versehenen Tankwän de mit einer selbstklebenden, korrosionsbeständigen Folie abgedeckt sind. Diese Maßnahme hat den Vorteil, daß die einen Oberflächen schutz gewährende Schutzschicht auf den Innenseiten der Tankwände vor der Feuchtigkeit durch die selbstklebende Folie geschützt wird. Dabei ist es zweckmäßig, für die selbstklebende Folie eine korro sionsbeständige Metallfolie, zum Beispiel eine Reinaluminiumfolie, zu benutzen. Es sind aber auch andere geeignete, selbstklebende, korrosionsbeständige Folien einsetzbar, wie zum Beispiel Folien aus Kunststoff oder aus Gold.The invention is therefore based on the object of a fuel tank to provide, the coated inner walls a long-term corrosion grant ons protection. This object is according to the invention solved in that the tank walls provided with the protective layer de covered with a self-adhesive, corrosion-resistant film are. This measure has the advantage that one surface protective layer on the inside of the tank walls is protected from moisture by the self-adhesive film. It is advisable to apply a corro for the self-adhesive film ion-resistant metal foil, for example a pure aluminum foil to use. But there are also other suitable, self-adhesive, corrosion-resistant foils can be used, such as foils made of Plastic or gold.
Die Erfindung wird anhand der beiliegenden Zeichnung näher erläutert, und zwar zeigt die Darstellung einen Ausschnitt eines Kraftstofftanks mit einer Tankwand 1, welche auf der Innenseite mit einer Oberflächenschutzschicht 2 beschichtet ist. Auf die Schutz schicht 2 ist eine selbstklebende Reinaluminiumfolie 3 aufgeklebt, welche eine sehr gute Korrosionsbeständigkeit besitzt.The invention is explained in more detail with reference to the accompanying drawing, namely the illustration shows a section of a fuel tank with a tank wall 1 , which is coated on the inside with a surface protective layer 2 . On the protective layer 2 , a self-adhesive pure aluminum foil 3 is glued, which has a very good corrosion resistance.
Außerdem ist ein flexibler Tanksack 4 dargestellt, der sich aufgrund der Tankfüllung und des aufgebrachten Druckes gegen die beschichtete Tankwand 1 anlegt. Zwischen dem Tanksack 4 und der Reinaluminiumfolie 3 ist Feuchtigkeit 5 angedeutet, welche jedoch wegen der Korrosionsbeständigkeit der Reinaluminiumfolie 3 diese nicht durchdringen kann. Die beschichtete Tankwand ist daher durch die Oberflächenschutzschicht 2 und die Reinaluminiumfolie 3 mit einer eine Langzeitwirkung erzielenden Schutzschicht versehen. In addition, a flexible tank bag 4 is shown, which rests against the coated tank wall 1 due to the tank filling and the applied pressure. Moisture 5 is indicated between the tank bag 4 and the pure aluminum foil 3 , which, however, cannot penetrate the pure aluminum foil 3 because of the corrosion resistance. The coated tank wall is therefore provided by the surface protective layer 2 and the pure aluminum foil 3 with a protective layer which has a long-term effect.
Der Einsatz der Folie aus Reinaluminium hat wegen ihrer guten Formbarkeit den zusätzlichen Vorteil, Unebenheiten, zum Beispiel durch Nietköpfe, ausgleichen zu können. Neben Folien aus korrosionsbeständigem Reinaluminium sind aber auch Folien aus Gold oder Kunststoff einsetzbar.The use of pure aluminum foil has because of its good Formability has the added benefit of bumps, for example with rivet heads. In addition to slides Corrosion-resistant pure aluminum is also made of foils Gold or plastic can be used.
