Abstract
Description
Bei der Erfindung handelt es sich um eine Erfindung aus dem Bereich Flugzeugtechnik / Flugzeugbau.The invention is an invention from the field of aircraft technology / aircraft construction.
Die Erfindung kann an allen Flugzeugen mit Fahrwerk unabhängig von Größe und Bauart eingesetzt werden.The invention can be used on all aircraft with landing gear, regardless of size and design.
Die Erfindung reduziert den Reifenverschleiß an Flugzeugreifen bei der Landung. Bisher werden beim Landen bzw. Aufsetzen des Flugzeugs auf die Landebahn die Reifen von Geschwindigkeit Null auf Landegeschwindigkeit (ca. 200 km/h und mehr) beschleunigt, was zu erheblichem Reifenverschleiß führt.The invention reduces tire wear on aircraft tires during landing. Until now, when the aircraft lands or touches down on the runway, the tires are accelerated from zero speed to landing speed (approx. 200 km/h and more), which leads to considerable tire wear.
Meine Problemlösung ist, dass sich die Fahrwerksreifen schon kurz vor dem Aufsetzen auf die Landebahn mit Landegeschwindigkeit drehen (ca. 200 km/h).My solution to the problem is that the landing gear tires rotate at landing speed (approx. 200 km/h) shortly before touching down on the runway.
Die Landegeschwindigkeit variiert und ist von vielen Faktoren abhängig, aus diesem Grund dürfen die Fahrwerksreifen nur mit der niedrigsten Landegeschwindigkeit drehen.Landing speed varies and depends on many factors, which is why the landing gear tires must only rotate at the lowest landing speed.
An den einzelnen Fahrwerksrädern sind beschaufelte Radscheiben, ähnlich einer Laufschaufelreihe einer Turbine angebracht, welche alle Fahrwerksräder durch den Fahrtwind in Drehung bringen, nachdem das Fahrgestell im Landeanflug ausgefahren wurde.Bladed wheel disks, similar to a row of turbine blades, are attached to the individual landing gear wheels, which cause all the landing gear wheels to rotate using the airflow after the landing gear has been extended during the landing approach.
Diese beschaufelten Radscheiben sind vom Durchmesser kleiner als die Reifen, aber mit den Rädern kraftschlüssig verbunden.These bladed wheel discs are smaller in diameter than the tires, but are frictionally connected to the wheels.
Die Bauart der beschaufelten Radscheiben muss dem einzelnen Flugzeugtyp angepasst sein.The design of the bladed wheel discs must be adapted to the individual aircraft type.
Sinngemäß wie unter Punkt 1. werden die Fahrwerksräder aber durch Elektromotoren angetrieben bis die Fahrwerkräder auf Landegeschwindigkeit drehen, was vom Piloten vorgegeben werden kann.As in point 1, the landing gear wheels are driven by electric motors until the landing gear wheels rotate to landing speed, which can be specified by the pilot.
Dadurch können für alle Landegeschwindigkeiten die optimalen Voraussetzungen erreicht werden.This allows optimal conditions to be achieved for all landing speeds.
Der Bremsvorgang unmittelbar nach der Landung erfolgt wie bisher mittels Umkehrschub der Triebwerke bei großen Flugzeugen und der Bremsen.The braking process immediately after landing is carried out as before by means of reverse thrust of the engines in large aircraft and the brakes.
