Eigenrotationsrad für FlugzeugfahrwerkSelf-rotating wheel for aircraft landing gear

Die Erfindung betrifft ein Eigenrotationsrad für Flugzeugfahrwerke gemäß den Ansprüchen 1 bis 8.The invention relates to a self-rotating wheel for aircraft landing gear according to claims 1 to 8.

Die Räder eines Flugzeugfahrwerkes befinden sich beim Landeanflug in relativer Ruhestellung. Die Flugzeugreifen herkömmlicher Bauart weisen nur eine Profilierung zur Wasseraufnahme auf.The wheels of an aircraft landing gear are in a relatively resting position during the approach to landing. Conventional aircraft tires only have a profile to absorb water.

Der in den Ansprüchen 1-8 angegebenen Erfindung liegt das Problem zugrunde, den Reifenverschleiß beim unmittelbaren Aufsetzen des Fahrwerkes sowie die Materialbelastungen im gesamten Flugzeügkörper zu verringern. The invention specified in claims 1-8 is based on the problem of reducing tire wear when the undercarriage immediately touches down as well as the material loads in the entire aircraft body.

Die Ereignisse in der Luftfahrt zeigen, daß die unmittelbare Landung eine kritische Phase darstellt. Im Moment der Landebahnberührung tritt ein ruckartiges schlingerndes Verhalten des Flugzeuges auf. Im wesentliehen sind es zwei Komponenten, die diesen Zustand verursachen:Events in aviation show that the immediate landing is a critical phase. The moment the aircraft touches the runway, it begins to jerk and lurch. There are essentially two components that cause this condition:

- Die Räder des Fahrwerkes werden aus einer relativen- The wheels of the chassis are made of a relative

keit entsprechende Drehzahl beschleunigt. Dadurch entsteht ein enormer Verschleiß der Reifen.speed corresponding to the speed. This causes enormous wear on the tires.

- Das Fahrwerk muß die beim Aufsetzen der Maschine wirkenden Kräfte kompensieren bzw. auf den Flugzeugkörper übertragen. Dieser Faktor wird hauptsächlich durch das Eigengewicht und die Sinkgeschwindigkeit des Flugzeuges sowie durch das subjektive Verhalten des Piloten beeinflußt. Dabei kommt es zu großen Materialbelastungen im Flugzeugkörper.- The landing gear must compensate for the forces acting when the aircraft touches down or transfer them to the aircraft body. This factor is mainly influenced by the weight and rate of descent of the aircraft as well as by the subjective behavior of the pilot. This results in large material loads in the aircraft body.

Diese Probleme werden mit den Maßnahmen der Ansprüche 1-8 gelöst.These problems are solved by the measures of claims 1-8.

Mit der Erfindung wird erreicht, daß die Räder vor der Landung in eine der Landungsgeschwindigkeit und der Landerichtung entsprechende Drehbewegung (Figur 1) versetzt werden und damit dieses Verschleißmoment erheblich reduziert wird. Dieser Effekt kann zum einen durch eine Veränderung am Reifen im Sinne eines Windrades erreicht werden, indem im Profil bzw. seitlich am Reifen Luftschaufeln (Figur 2) angebracht werden, die den beim Landeanflug herrschenden Luftstrom auf das Rad übertragen und dieses in eine entsprechende Eigenrotation versetzen (Figur 1) oder zum anderen durch einen separaten, vom Cockpit in Gang zu setzenden Antrieb des gesamten Rades erfolgen.The invention ensures that the wheels are set in a rotational movement (Figure 1) corresponding to the landing speed and the landing direction before landing, thus significantly reducing this wear moment. This effect can be achieved by changing the tire in the manner of a wind turbine, by attaching air vanes (Figure 2) to the profile or to the side of the tire, which transfer the air flow prevailing during the landing approach to the wheel and cause it to rotate accordingly (Figure 1), or by a separate drive for the entire wheel that can be activated from the cockpit.

Vorteilhafte Wirkungen der Erfindung ergeben sich durch enorme Verringerungen des Reifenverschleißes mit allen damit im Zusammenhang stehenden finanziellen und wirtschaftlichen Auswirkungen für die Fluggesellschaften, die Flugzeugproduzenten sowie für die Reifen- und RohstoffIndustrie, zum weiteren durch die höhere Stabilität der Flugzeuge beim Auf-Advantageous effects of the invention result from enormous reductions in tire wear with all the associated financial and economic effects for the airlines, the aircraft manufacturers as well as for the tire and raw material industries, and furthermore through the increased stability of the aircraft when taking off.

Ein Ausführungsbeispiel der Erfindung wird an Hand der Figuren 1 und 2 erläutert. Es zeigen Figur 1 eine Prinzipdarstellung und Figur 2 die angedeuteten Luftschaufeln im Reifenprofil gemäß Anspruch 3.An embodiment of the invention is explained with reference to Figures 1 and 2.
