Abstract
Description
Beim Aufsetzen eines Flugzeuges ist es nachteilig, daß die Räder unmittelbar bei hoher Geschwindigkeit durch den Kontakt mit der Landebahn angetrieben werden. Durch die Massenträgheit der schweren Räder rollen die Räder in diesem Moment nicht mehr ab, sondern schleifen durch. Die Abnutzung der Reifen ist daher bei jeder Landung sehr hoch. Es wäre deshalb von Vorteil, diesen momentanen Reifenabrieb zu vermindern.When placing an aircraft, it is disadvantageous that the wheels are driven directly at high speed by the contact with the runway. Due to the inertia of the heavy wheels, the wheels do not roll off at this moment, but grind through. The wear of the tires is therefore very high with each landing. It would therefore be advantageous to reduce this momentary tire wear.
Der Erfindung liegt deshalb die Aufgabe zugrunde, Flugzeugfahrwerke der eingangs bezeichneten Art zu schaffen, bei denen die Reifen im Moment der Landung nicht durchschleifen sondern abrollen.The invention is therefore an object of the invention to provide aircraft landing gear of the type described, in which the tires at the moment of landing not loop through but unroll.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Innenseiten der Räder mit Turbinenschaufeln besetzt sind, daß an den Frontseiten der Fahrwerke Einlaßkanäle angeordnet sind, daß die Luftströmung durch die Einlaßkanäle mit Düsen auf die Turbinenschaufeln gelenkt wird, daß dadurch einfache Turbinen gebildet werden, daß durch die Auslegung der Turbinen die Drehzahl der Räder beim Landeanflug bestimmt wird, daß bei dieser Drehzahl die Reifen beim Kontakt mit der Landebahn synchron abrollen, daß dadurch der Reifenabrieb stark vermindert wird, und daß die komplizierte Mechanik der Fahrwerke durch die einfachen Turbinen nicht gestört wird.According to the invention, this object is achieved in that the inner sides of the wheels are occupied by turbine blades that are arranged on the front sides of the chassis intake ports that the air flow is directed through the inlet ports with nozzles on the turbine blades, that thereby simple turbines are formed by the design of the turbines, the speed of the wheels is determined when approaching that at this speed the tires roll in contact with the runway synchronously, thereby greatly reducing the tire wear, and that the complicated mechanics of the chassis is not disturbed by the simple turbines.
In weiterer Ausgestaltung der Erfindung können auf die Außenseiten der Radfelgen als einfachste Lösung Savonius-Rotoren aufgesetzt werden.In a further embodiment of the invention can be placed on the outer sides of the wheel rims as the simplest solution Savonius rotors.
In anderer Ausgestaltung der Erfindung können als aufwendigste Lösung die Räder elektromotorisch angetrieben werden.In another embodiment of the invention, the wheels can be driven by an electric motor as the most expensive solution.
Dadurch ergeben sich folgende Vorteile:This results in the following advantages:
Die Reifen werden bei der Landung nur noch gering abgenutzt.The tires are only slightly worn when landing.
Dies ist ein wirtschaftlicher Vorteil, weil weniger Reifen benötigt werden und der Zeitaufwand für die Reifenwechsel verringert wird.This is an economic advantage because fewer tires are needed and the time required to change tires is reduced.
Die Erfindung wird an Beispielen anhand schematischer Zeichnungen näher erläutert. Es zeigt:The invention will be explained in more detail by way of examples with reference to schematic drawings. It shows:
Die Anordnung der Einlaßkanäle
Bei einer anderen Lösung (nicht eingezeichnet) können die Räder sehr genau elektromotorisch angetrieben werden. Da die Fahrwerke aber äußerst kompliziert aufgebaut sind, wäre eine weitere Komplikation sehr aufwendig.In another solution (not shown), the wheels can be driven very accurately by electric motor. However, since the landing gears are extremely complicated, another complication would be very costly.
