Description
Auf manchen Flugplätzen befinden sich am Ende der Landebahn Hindernisse, die bei einem unbeabsichtigten Überrollen der Landebahnbegrenzung für Flugzeuge und Insassen eine große Gefahr darstellen. Man hat deshalb bereits vorgeschlagen, zwischen dem Ende der Landebahn. und dem betreffenden Hindernis ein Fangnetz anzuordnen. Insbesondere wurde der Vorschlag gemacht, dieses quer zur Landerichtung gespannte Fangnetz an seinen beiden Enden mit schweren Ketten zu belasten, welche die gewünschte Bremswirkung herbeiführen sollen. Bei diesen bekannten Einrichtungen wird das ausrollende und abzufangende Flugzeug ungewöhnlich. starken Beanspruchungen ausgesetzt, die leicht zu .erheblichen Schäden führen können. Bei der Verwendung von schweren Ketten als Bremsgewichte müssen diese oberhalb der Landebahn verlegt werden, was ein zusätzliches Hinderndes für die landenden Flugzeuge darstellt. Außerdem erfordern die bisher gebräuchlichen Abfangeinrichtungen einen erheblichen Aufwand an Bedienungspersonal.At some airports there are obstacles at the end of the runway, those in the event of an unintentional rollover of the runway boundary for aircraft and occupants pose a great danger. It has therefore already been suggested between the end of the runway. and to arrange a safety net for the obstacle in question. In particular, the suggestion was made to stretch this across the direction of landing To load the safety net at both ends with heavy chains, which the desired To bring about braking effect. In these known devices, the roll-out and aircraft to be intercepted unusual. exposed to heavy use, the can easily lead to .considerable damage. When using heavy chains as braking weights, these must be laid above the runway, which is an additional Represents an obstacle for the landing aircraft. In addition, they require so far Customary interception devices require a considerable effort for operating personnel.
Die geschilderten Nachteile werden durch die Erfindung vermieden.The described disadvantages are avoided by the invention.
In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel erläutert. Es zeigt Fig. r eine Draufsicht und Fig. 2 eine Seitenansicht der Abfang- und Bremsvorrichtung, Fig. 3 einen Rohrabschnitt mit Druckkolben, -Überströmventid und .zentral geführtem Zugkabel im Längsschnitt und Fig. ,4 einen Querschnittlurch die Rohrleitung nach der Linie A-B der Fig. 3.In the drawing, the invention is explained using an exemplary embodiment. It shows Fig. R a plan view and Fig. 2 a side view of the interception and braking device, Fig. 3 shows a pipe section with pressure piston, overflow valve and .zentral guided Pull cable in longitudinal section and Fig. 4 shows a cross section through the pipeline the line A-B of FIG. 3.
An Stelle der bisher üblichen Bremsketten sind gemäß der Erfindung an ' den: beiden Enden des quer zur Landerichtung gespannten Fangnetzes z Zugkabel 2 befestigt, .die ihrerseits in je einer als Druckflüssigkeit.s- oder Drwckgaszylinder ausgebildeten und mehrere hinterei.nandergeschaltete Druckkolben mit in Anflugrichtung zunehmend kleiner werdenden Überströmventilöffnungen 5 od. dgl. aufweisenden Rohrleitung 3 derart zentralgeführt sind, daß sie die auf Rollen 6 od. dgl. laufenden Druckkolben q., in Landerichtung gesehen, zusammenzieht. Dabei laufen die Kolben dicht aufeinander auf. In dieser Endstellung werden sie durch. an der Stirnseite der Rohrleitungen angeordnete Federn 7 abgefangen. Dadurch erfolgt auf verhältnismäßig kurzem Weg ein wirksames und zugleich verhältnismäßig weiches Abfangen der Flugzeuge.Instead of the conventional brake chains are according to the invention at 'the: both ends of the safety net stretched across the landing direction z pulling cable 2 attached, in turn in one each as a pressure fluid or pressure gas cylinder trained and several pressure pistons connected one behind the other with in the approach direction increasingly smaller overflow valve openings 5 or the like 3 are centrally guided in such a way that they the pressure piston running on rollers 6 or the like q., seen in the direction of landing, contracts. The pistons run close together on. In this end position they are through. on the face of the pipelines arranged springs 7 intercepted. This takes place on a relatively short route an effective and at the same time relatively soft interception of the aircraft.
In weiterer Ausbildung des Erfindungsgedankens wird vorgeschlagen, die als Bremszylinder dienenden Rohrleitungen unter Flur zu verlegen.In a further development of the inventive concept, it is proposed that to lay the pipes serving as brake cylinders under the floor.
Die erfindungsgemäße Einrichtung arbeitet selbsttätig und benötigt nur wenig Personal für ihre Wartung.The device according to the invention works automatically and is required few staff for their maintenance.
