Abstract
The invention relates to a method for rapidly deploying an emergency parachute. According to said method, at the latest at the end of the blast-off path the parachute (1) is jerked backward in the direction of the object which has to be decelerated and landed. This causes the parachute to open immediately. The method allows for the use of such parachutes even close to the ground.

Verfahren zum Öffnen eines Rettungsfallschirms und Fallschirmsystem mit einem verfahrensgemäss betätigten FallschirmMethod for opening a rescue parachute and parachute system with a parachute operated according to the method
Die vorliegende Erfindung betrifft ein Verfahren zum Betätigen und Offnen eines gegebenenfalls mit einer Spreizmechanik verse- henen Fallschirms, bei welchem ein geschlossener, über eine Verbindungsleine mit einem gegebenenfalls zur gebremsten Landung zu bringenden Gegenstand verbundener Fallschirm vom Gegenstand weggeschossen und die Spreizung des Schirms eingeleitet wird, sowie ein verfahrensgemäss betätigtes Fallschirmsystem.The present invention relates to a method for actuating and opening a parachute, optionally provided with a spreading mechanism, in which a closed parachute, which is connected via an attachment line to an object to be brought to a braked landing, is shot away from the object and the spreading of the parachute is initiated, as well as a parachute system operated according to the procedure.
Rettungsschirme werden seit langem bei Fluggeräten eingesetzt, sei dies zum Retten des Piloten oder des Fluggerätes selbst .Rescue parachutes have long been used in aircraft, be it to save the pilot or the aircraft itself.
Die richtig dimensionierten Fallschirme erfüllen bei ordnungs- gemässem Funktionieren die gestellte Aufgabe, vorausgesetzt, der zu rettende Gegenstand befindet sich in ausreichendem Ab- stand über dem Boden. Der Grund hierfür liegt darin, dass jeder Fallschirm eine gewisse Zeit benötigt, um sich zu öffnen und damit die angestrebte Wirkung zu entfalten.The properly dimensioned parachutes, when properly functioning, do the job, provided the object to be rescued is at a sufficient distance above the ground. The reason for this is that each parachute needs a certain amount of time to open and thus have the desired effect.
Die Öffnung eines Fallschirms kann durch teilweise recht komplizierte Spreizmechanismen beschleunigt werden. Es hat sich jedoch gezeigt, dass solche Vorkehren noch nicht ausreichen, um eine sehr rasche Öffnung zu bewirken, so dass die Wirkung in Bodennähe immer noch unmöglich bzw. zumindest fragwürdig ist.The opening of a parachute can be accelerated by sometimes quite complicated spreading mechanisms. However, it has been shown that such measures are not yet sufficient to bring about a very rapid opening, so that the effect close to the ground is still impossible or at least questionable.
Aufgabe der vorliegenden Erfindung war es, ein Verfahren zu schaffen, welches eine ausserordentlich rasche Betätigung und Öffnung des Fallschirms erlaubt .The object of the present invention was to provide a method which allows an extremely rapid actuation and opening of the parachute.
Diese Aufgabe wurde bei einem Verfahren der eingangs definierten Art erfindungsgemäss durch die Merkmale der Ansprüche 1 und 5 gelöst .
- 2 -This object was achieved according to the invention in a method of the type defined at the outset by the features of claims 1 and 5. - 2 -
Besondere Ausführungsformen der Erfindung sind in den abhängigen Ansprüche definiert .Particular embodiments of the invention are defined in the dependent claims.
Die Erfindung basiert auf der Erkenntnis, dass ein rasches Öffnen eines Fallschirms dann erfolgt, wenn dieser mit einer ruck- artigen Bewegung bzw. Kraft "zurückgezogen" wird.The invention is based on the knowledge that a parachute opens quickly when it is "pulled back" with a jerky movement or force.
Bei heutigen Rettungssystemen werden die Fallschirme weggeschossen. Zur Realisierung des Erfindungsgedankens musste deshalb entgegen der Wegschiessrichtung auf den Schirm eingewirkt werden, und dies möglichst schon, bevor die Verbindungsleine vollständig "ausgezogen" ist.With today's rescue systems, the parachutes are shot away. In order to realize the inventive idea, it was therefore necessary to act on the screen against the direction of shooting away, and if possible before the connecting line was completely "pulled out".
Die Erfindung wird nachstehend anhand von in der Zeichnung rein schematisch dargestellten Realisierungsformen noch etwas näher erläutert .The invention is explained in more detail below on the basis of implementation forms shown purely schematically in the drawing.
Es zeigt :It shows :
Fig. 1 eine erste Ausführungsform eines Fallschirmsystems mit fester Verbindungsleine,1 shows a first embodiment of a parachute system with a fixed connecting line,
Fig. 2 eine ähnliche Darstellung wie Fig. 1, mit gummielastischer Verbindungsleine undFig. 2 is a similar representation as Fig. 1, with rubber-elastic connecting line and
Fig. 3 eine weitere Ausführungsform, mit Hilfsleine.Fig. 3 shows another embodiment, with auxiliary line.
Bei sämtlichen in der Zeichnung schematisch dargestellten Fallschirmsystemen geht es darum, im Notfall bzw. Bedarfsfall den geschlossenen bzw. verpackten Fallschirm 1 vom zu einer gebrem- sten Landung zu bringenden Gegenstand 2, z.B. einem Fluggerät, Schleudersitz etc., wegzuschiessen (mittels Treibladung, Rake- te) . Der Fallschirm 1 ist über eine Verbindungsleine 3 mit dem Gegenstand 2 verbunden.
- 3 -All of the parachute systems shown schematically in the drawing are about shooting the closed or packaged parachute 1 away from the object 2 to be brought to a braked landing, for example an aircraft, ejection seat, etc. (by propellant charge, rake - te). The parachute 1 is connected to the object 2 via a connecting line 3. - 3 -
Wie bereits weiter oben erwähnt, geht es darum, den weggeschossenen Fallschirm 1 spätestens am Ende der Verbindungsleine ruckartig wieder in Richtung des Gegenstandes 2 zurückzuziehen, damit sich der Fallschirm 1 rasch öffnet.As already mentioned above, it is a question of pulling the parachute 1 that has been shot away at the end of the connecting line back towards the object 2 so that the parachute 1 opens quickly.
Das Wegschiessen und ruckartige Zurückziehen und damit Öffnen des Schirms geht sehr rasch vor sich (Sekundenbereich) , so dass sich der Rettungsfallschirm auch für den Gebrauch in Bodennähe eignet .The shooting away and jerky retraction and thus opening the parachute takes place very quickly (seconds range), so that the rescue parachute is also suitable for use near the ground.
Bei der Ausführungsform nach Fig. 1 ist die Verbindungsleine 3 auf Seite des Gegenstandes 2 mit einer motorischen Aufspulvorrichtung 4 verbunden, welche nach vollständigem Ausfahren der Leine 3 diese unverzüglich automatisch zurückzieht (Rückspulung z.B. durch Federmotor, welcher durch Ruck am Ende der Leine ausgelöst wird) . Durch das ruckartige Zurückziehen wird der Fallschirm sofort geöffnet (Zehntelssekunden) .In the embodiment according to FIG. 1, the connecting line 3 on the side of the object 2 is connected to a motorized winding device 4 which, after the line 3 has been fully extended, automatically pulls it back (rewinding, for example by a spring motor, which is triggered by a jerk at the end of the line). . By pulling back suddenly, the parachute opens immediately (tenths of a second).
Bei der Ausführungsform nach Fig. 2 besteht die Verbindungsleine 3 aus einem gummielastischen Material. Die Leine wird ge- spannt, und am Ende des Spannweges wird sie die gespeicherte Energie zum Rückzug des Fallschirms 1 einsetzen. Die nach dem Rückzug lose Leine 3 wird vorzugsweise durch einen Aufspulme- chanismus 4' teilweise aufgespult, damit die Wirkung des Fallschirms 1 sofort eintreten kann.In the embodiment according to FIG. 2, the connecting line 3 consists of a rubber-elastic material. The line is tensioned and at the end of the tensioning path it will use the stored energy to retract the parachute 1. The line 3 which is loose after the retraction is preferably partially wound up by a winding mechanism 4 ', so that the action of the parachute 1 can take place immediately.
Bei der Ausführungsform nach Fig. 3 schliesslich ist neben der Verbindungsleine 3 eine Hilfsleine 3' vorgesehen. Diese ist z.B. an den Punkten A und B am Schirm 1 befestigt und am Gegenstand 2 über eine Umlenkrolle 4" geführt.Finally, in the embodiment according to FIG. 3, an auxiliary line 3 'is provided in addition to the connecting line 3. This is e.g. attached at points A and B to the screen 1 and guided on the object 2 via a deflection roller 4 ".
Gegen Ende der Wegschiessstrecke wird die Hilfsleine 3 ' am Punkt A in Richtung vom Gegenstand weg mitgezogen und wird da-
- 4 -Towards the end of the shooting distance, the auxiliary line 3 'at point A is pulled in the direction away from the object and is there - 4 -
mit am Punkt B angreifend den Schirm 1 ruckartig zurückziehen und dessen rasche Öffnung bewirken.with the point B attacking pull back the screen 1 and cause it to open quickly.
Ob anfänglich die Verbindung zwischen Fallschirm 1 und Gegenstand 2 über die Leine 3 oder die Hilfsleine 3' erfolgt, ist belanglos .
It is irrelevant whether the connection between parachute 1 and object 2 initially takes place via line 3 or auxiliary line 3 '.
