BeschreibungDescription

Stand der TechnikState of the art

Die Bereifung eines Flugzeugfahrwerks ist bei der Landung einem abnormal hohen Verschleiß ausgesetzt. Wenn die Räder auf der Landebahn aufsetzen, radieren die Reifen bis die Räder die Drehzahl erreicht haben, die der Landegeschwindigkeit entspricht. Das ist zu vergleichen mit einer Vollbremsung eines Rennwagens aus Höchstgeschwindigkeit. Die Lauffläche der Reifen verbrennt und wird abradiert, sodaß schon nach wenigen Landungen die Bereifung erneuert werden muß.The tires on an aircraft's landing gear are subject to abnormally high levels of wear during landing. When the wheels touch down on the runway, the tires wear down until the wheels reach the speed that corresponds to the landing speed. This can be compared to an emergency stop on a racing car from top speed. The tread of the tires burns and is worn away, so that the tires have to be replaced after just a few landings.

AufgabeTask

Der hohe Verschleiß der Bereifung eines Flugzeugs kann ganz erheblich reduziert werden, wenn die Räder vor dem Aufsetzen auf die Landebahn bereits die Drehzahl aufweisen, die der Landegeschwindigkeit entspricht. Das kann erfolgen durch in die Radnaben eingebaute Motoren, die je nach Flugzeugtyp und den vorhandenen Möglichkeiten, entweder elektrisch, hydraulisch, pneumatisch oder durch den Staudruck des Fahrtwindes angetrieben werden.The high level of wear and tear on an aircraft's tires can be significantly reduced if the wheels are already running at the speed that corresponds to the landing speed before touching down on the runway. This can be achieved by installing motors in the wheel hubs, which, depending on the aircraft type and the available options, are powered either electrically, hydraulically, pneumatically or by the dynamic pressure of the airstream.

Damit wird erreicht, daß die Reifen beim Aufsetzen auf die Landebahn nicht radieren, sondern gleich abrollen und der Verschleiß auf ein Minimum reduziert wird.This ensures that the tires do not skid when they touch down on the runway, but roll off immediately and wear is reduced to a minimum.
