Abstract

The invention relates to an accelerator wheel for aircraft wheels of any type and for any aircraft. A rotary movement of the wheels in the direction of flight is required during landing for all aircraft wheels, which rotary movement corresponds to the speed of the aircraft on landing. The accelerator wheel accelerates the aircraft wheels in the required rotary movement and rotation direction. All aircraft, irrespective of whether they are transport aircraft, passenger aircraft, light aircraft or combat aircraft still land with stationary wheels even today. This object is achieved according to the invention in that an accelerator wheel per tyre or pair of tyres accelerates the wheels to have the necessary rotary movement, rotation direction and rotation speed as a result of the air pressure which occurs when the undercarriage is extended. The accelerator wheel is placed rigidly, or with a step up, onto the aircraft wheel as an air impeller which is provided with the desired rotary movement as a result of the shaping of its vanes. The accelerator wheel can be installed in any aircraft, even retrospectively, without any major technical modification and cost outlay. The drawing contains the stylised side view of an aircraft wheel. The items in the drawing are: direction of flight g, rotation direction f, aircraft tyre a, wheel rim b, wheel axle c, accelerator wheel D, impeller vanes E. <IMAGE>

Description

Beschleunigerrad für Flugzeugräder Accelerator wheel for aircraft wheels

Die Erfindung betrifft ein Beschleunigerrad für Flugzeugräder jeglicher Art, für jedes Flugzeug.The invention relates to an accelerator wheel for aircraft wheels of any kind Kind, for any aircraft.

Bei allen Flugzeugrädern ist beim Landen eine Drehbewegung der Räder in Flugrichtung erforderlich, die der Geschwindigkeit des Flugzeuges beim Landen entspricht. Ds Beschleunigerrad bringt die Flugzeugräder in die erforderliche Drehbewegung und Drehrichtung. Alle Flugzeuge, egal ob Transport-, Passaaier-,Snort- oder Kampfflugzeuge landen bis heute noch mit stillstehenden Rädern. Derzeit gibt es keine technische oder andere Einrichtung die den Flugzeugrädern die nötige Drehbewegung verleiht.With all aircraft wheels, there is a turning movement of the wheels when landing in the direction of flight required that of the speed of the aircraft when landing is equivalent to. The accelerator wheel brings the aircraft wheels into the required rotary motion and direction of rotation. All aircraft, regardless of whether they are transport, passenger, snort or combat aircraft still land with stationary wheels to this day. There is currently no technical or other device that gives the aircraft wheels the necessary rotational movement.

Der erfindung liegt die Aufgabe zugrunde, die Flugzeugräder ohne großen Kostenaufwand in die nötige Drehbewegung zu versetzen. Diese Aufgabe wird Erfindungsgemäß dadurch gelöst, daß ein Beschleunigerrad pro Reifen oder @eifenpaar, bei:l Ausfahren des Fahrwerkes durch den anstehenden Luftdruc' die Räder in die nötige Drehbewegung, Drehrichtung und Drehgeschwindigkeit versetzt. Des Beschleunigerrad wird als Luftschaufelrad aVf das Flugzeugrad starr oder mit Übersetzung, aufges@tzt welches durch die Formgebung seiner Luftschaufeln das Flugzeugrad in die angestrebte Bewegung versetzt.The invention is based on the task of the aircraft wheels without large To put costs in the necessary rotary movement. This object is achieved according to the invention solved by the fact that one accelerator wheel per tire or pair of tires when: l extending of the undercarriage by the pending air pressure, the wheels in the necessary rotary motion, Direction and speed of rotation offset. The accelerator wheel is called an air paddle wheel aVf the aircraft wheel rigid or with translation, which is supported by the shape its air blades set the aircraft wheel in the desired motion.

Die 1 mit der Erfindung erzielten Vorteile bestehen darin, daß die Flugzeugräder in Flugrichtung mit der Flubgeschwindigkeit gleichzusetzender Geschwindigkeit, gedreht werden. Dadurch wird bei der Landung die ruckartige Beschleunigung der Räder auf der Landebahn vermieden. Die Thermische- und Abriebbelastung der Reifen wird erheblich vermindert. Dadurch steigt die Lebensdauer der Reifen. Die Gedahr eines Reifenplatzens und/oder Reif nbrandes bei und nach der Landung wi rd erheblich vermindert.The 1 achieved with the invention are that the Aircraft wheels in the direction of flight with a speed to be equated with the flight speed, to be turned around. This causes the wheels to accelerate jerkily when landing avoided on the runway. The thermal and abrasion load on the tires is considerably reduced. This increases the service life of the tires. The thought of one Tire bursting and / or tire fire during and after landing is considerably reduced.

Die Umweltb@l@stigung durch das Kreischen der aufsetzenden Reifen und durch die Gestankswolke wird vermieden.The environmental pollution caused by the screeching of the tires and through the cloud of stench is avoided.

Ein Ruck beim Aufsetzen/Landen wird vermieden, zumindest verringert. Der Flugkomfort wird dadurch gesteigert. Auch eine Verschmutzung der Landebahn durch Reifenabrieb wird ver@inder. Der Einbau ist einfach und Ohne große Änderung, in jedes Flugzeug möglich.A jolt when touching down / landing is avoided, or at least reduced. This increases flight comfort. Also a pollution of the runway by Tire wear is reduced. The installation is simple and without major changes in any aircraft possible.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird irn folgenden näher beschrieben. Es zeigen Fig.: 1 Eine stilisierte Seitenansicht eines Flugzeugrades mit Flugrichtung g, und der angestrebten Drehrichtung f. Es sind in der Zeichnung enthalten: Der Flugzeugreifen a, die Radfelge b, die Radacnse c, und ein mit der Radfelge starr verbundenes Beschleunigerrad D, Luftechaufeln E, Flugrichtung g, und Drehrichtung f.An embodiment of the invention is shown in the drawing and is described in more detail below. The figures show: 1 A stylized side view of an aircraft wheel with flight direction g, and the desired direction of rotation f. Es are included in the drawing: The aircraft tire a, the wheel rim b, the wheel rim c, and an accelerator wheel D rigidly connected to the wheel rim, air blades E, direction of flight g, and direction of rotation f.

Fig.: 2 Eine stilisierte wrontansicht eines Flugzeugrades. Die seitliche Anbringung des Beschleunigerrades D, ist d@raus besonders gut ersichtbar.Fig .: 2 A stylized front view of an aircraft wheel. The side Attachment of the accelerator wheel D is particularly easy to see from there.

Ob links, rechts, beidseitig, der Durchmesser und e'ie Tiefe des Beschleunigerrades rnrd vo de@ jeweiligen Flugzeugtyp abhängig sein, ist jedoch beliebig flexibel. Whether left, right, on both sides, the diameter and depth of the Accelerator wheel depends on the type of aircraft, however flexible as required.
