Abstract
Description
Die Erfindung betrifft einen Flugzeugreifen, der mit Windfangelementen an der Reifenaußenwand ausgestattet ist (flexibel, starr, originärer Bestandteil des Reifens oder nachträglich angefügt mit oder ohne Teilabdeckung des Reifens) um diesen vor der Landung in Rotation zu versetzen.The Invention relates to an aircraft tire with windscreen elements on the outer tire wall is equipped (flexible, rigid, original component of the tire or later added with or without partial coverage of the tire) around the tire before landing to rotate.
Hauptsächlich auf grund des Verschleißes bei der Landung müssen Flugzeugreifen häufig ausgetauscht werden, was zu erheblichen Kosten und Umweltbelastung führt. Dieser hohe Verschleiß tritt auf, da zwischen der unteren (aufsetzenden) Reifenlauffläche und der Landebahn eine hohe Relativgeschwindigkeit besteht, die beim Aufsetzen zu starkem Abrieb führt.Mostly on due to wear landing Airplane tires often be exchanged, resulting in significant costs and environmental pollution leads. This high wear occurs because between the lower (touching down) tire tread and the runway has a high relative speed, which at Put on leads to strong abrasion.
Dieser Verschleiß kann signifikant verringert werden, in dem man die Flugzeugreifen vor dem Aufsetzen in Rotation versetzt und so die Relativgeschwindigkeit zwischen Reifenunterseite und Landebahn verringert.This Can wear can be significantly reduced by looking at the aircraft tires put in rotation and so the relative speed between the underside of the tire and the runway.
Bisherige Ansätze sehen technische Lösungen in und an der Felge vor. Diese sind jedoch nur mäßig effektiv, da bei diesen Konzepten die Windfangelemente nahe an der Nabe liegen und durch das geringe Drehmoment nur kleine Effekte erzielen.Previous approaches see technical solutions in and on the rim in front. However, these are only moderately effective because of these Concepts that the windscreen elements are close to and through the hub the low torque only achieve small effects.
Andere Konzepte sehen komplexe ausfahrbare mechanische Systeme innerhalb der Felge vor, deren Anschaffungs- und Wartungskosten den bei den Reifen erreichten wirtschaftlichen Vorteil neutralisieren oder übersteigen.Other Concepts see complex extendable mechanical systems within the rim, the acquisition and maintenance costs of which the Tires neutralize or exceed the economic advantage achieved.
Zusätzlich haben radial ausfahrbare Systeme den Nachteil, dass durch das Nachgeben des Reifens bei Belastung die Windfangelemente die Bahn berühren können, was dann an diesen Verschleiß hervorruft, der zusätzlich gewartet werden muss.Additionally have radially extendable systems have the disadvantage that by giving in of the tire under load, the windscreen elements can touch the track, what then causes this wear, the additional needs to be serviced.
Im Rahmen des vorliegenden Patenanspruchs wird durch aerodynamische Formgebung und die durch die Startgeschwindigkeit erzeugte Rotation der zusätzliche Luftwiderstand beim Start weitgehend kompensiert und ist zu vernachlässigen.in the The present patent claim is supported by aerodynamic Shaping and the rotation generated by the starting speed the additional Air resistance at the start largely compensated and can be neglected.
Da die Windfangelemente aus Gummi, Stoff, Fallschirmseide, etc. oder auch anderen geeigneten Werkstoffen gefertigt werden können wird die Struktur und damit die Stabilität und Flexibilität des Flugzeugreifens nicht negativ beeinträchtigt.There the windscreen elements made of rubber, fabric, parachute silk, etc. or other suitable materials can be manufactured the structure and thus the stability and flexibility of the aircraft tire not adversely affected.
Die Erfindung stellt einen Flugzeugreifen bereit, der durch seine Gestaltung (ggf. in Verbindung mit einer Teilabdeckung des Reifens), insbesondere seiner Oberflächengestaltung, in einem Luftstrom, insbesondere vor der Landung (dem Aufsetzen), in Rotation versetzt wird und damit den durch Abrieb verursachten Verschleiß beim Aufsetzen signifikant verringert.The Invention provides an aircraft tire, which by its design (if necessary in connection with a partial covering of the tire), in particular its Surface design, in an air stream, especially before landing (touchdown), is set in rotation and thus caused by abrasion Wear at Touchdown significantly reduced.
