Verfahren zur Auslösun« der EntfaltunpsvorrichtunSProcedure for triggering the deployment device
von Reservefalischirmen.of reserve parachutes.
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Auslösung der Entfaltungsvorrichtung von Reservefallschirmen.The present invention relates to a method of triggering the deployment device of reserve parachutes.
Für automatische Fallschirmsprünge werden Fallschirme verwendet, die durch eine Schnur mit dem Flugzeug verbunden sind. Beim Absprung reißt die Schnur durch und bewirkt durch den dabei auftretenden Zug am Auslösemechanismus das Entfalten des Hauptschirmes.For automatic parachute jumps, parachutes are used that connected to the aircraft by a cord. When jumping, the line breaks through and causes the unfolding through the pull that occurs on the release mechanism of the main screen.
Neben diesem Haupt schirm wird sicherheitshalber ein Reserveschirm mitgeführt, der beim Versagen des Hauptschirmes von Hand ausgelöst werden kann. Wenn bei Absprungverletzungen oder durch Nervosität die Handauslösung unterbleibt, ist keine Rettung für den Fallschirmspringer gegeben. Eine Möglichkeit zur Entfaltung des Reserveschirmes ohne Aktivität des Springers ist daher erwünscht.In addition to this main parachute, there is a reserve parachute to be on the safe side which can be triggered manually if the main parachute fails. If the hand is not released due to jumping injuries or due to nervousness, there is no rescue for the parachutist. An opportunity for development the reserve parachute is inactive by the jumper therefore desirable.
Vorgeschlagen sind bereits Verfahren, bei denen ein Luftdruckfühler die Auslösung des Reserveschirmes bewirkt. Diese Verfahren sind unsicher und kompliziert, da der jeweils am Boden herrschende Luftdruck genau eingestellt werden muß und außerdem eine automatische Blockierung der Auslösung wirksam werden muß, wenn sich im Regelfall der Haupt schirm vollständig entfaltet hat.Methods have already been proposed in which an air pressure sensor triggers the reserve parachute. These procedures are unsafe and complicated, because the air pressure prevailing on the ground must be precisely adjusted and moreover an automatic blocking of the tripping must take effect when it is normally the main screen has fully unfolded.
Aufgabe der vorliegenden Erfindung ist es deshalb ein Verfahren zur Auslösung der Entfaltungsvorrichtung von Reservefallschirmen bei einem Versagen des Hauptfallschirmes anzugeben, daß die Nachteile der bekannten Verfahren beseitigt.The object of the present invention is therefore a method for Deployment of the reserve parachute deployment device in the event of failure of the main parachute to indicate that the disadvantages of the known methods are eliminated.
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß die Auslösung von dritter Seite durch Funkfernsteuerung vom Boden oder vom Absprungflugzeug erfolgt, wobei eine ungewollte Auslösung durch funktechnische Fremdeinwirkungen mittels einer speziellen Kodierung des Funkauslösesignals verhindert wird.According to the invention, this object is achieved in that the release from a third party by radio remote control from the ground or from the take-off aircraft, an unintentional triggering by external radio interference by means of a special coding of the radio trigger signal is prevented.
Vorteilhaft wirkt sich das erfindungsgemäße Verfahren dahingehend aus, daß bei Verletzung, Bewegungsunfähigkeit oder Nervosität des Springers die rechtzeitige Auslösung des Reserveschirmes möglich ist.The method according to the invention has an advantageous effect in this regard from the fact that in the event of injury, inability to move or nervousness of the jumper, the timely release of the reserve parachute is possible.
Die komplizierten Luftdrucksensoren der bekannten Verfahren mit den mechanischen Verstärkern zum Betätigen des Auslösemechanismus entfallen. Au3erdem entfallen die Blockierungseinrichtungen, die durch den entfalteten Haupt schirm betätigt werden.The complicated air pressure sensors of the known methods with the mechanical amplifiers for actuating the trigger mechanism are not required. Besides there are no blocking devices that screen through the unfolded main be operated.
Bei nur teilweise entfalteten Hauptschirm kann vom Boden oder vom Flugzeug aus mit Sicherheit entschieden werden, ob der Reserveschirm erforderlich ist, oder nicht.If the main umbrella is only partially unfolded, the floor or the From the aircraft it will be decided with certainty whether the reserve parachute is required is or not.
Gemäß einer weiteren Ausgestaltung der Erfindung wird dem Fallschirmspringer über Zusatzkanäle der Funkfernsteuerung die Betriebsbereitschaft der Fernauslösung optisch oder akustisch an der Entfaltungsvorrichtung des Reservefallschirmes signalisiert. Darüberhinaus können dem Springer über einen Funksprechkanal Anweisungen vom Boden oder vom Flugzeug - unabhängig von der Entfaltung des Reserveschirmes - gegeben werden.According to a further embodiment of the invention, the parachutist the operational readiness of the remote release via additional channels of the radio remote control signaled optically or acoustically on the deployment device of the reserve parachute. In addition, the jumper can receive instructions from the ground via a radio communication channel or from the aircraft - regardless of the deployment of the reserve parachute will.
Zur Auslösung des Reserve schirmes wird vorgeschlagen, daß ein pressgas - oder batteriebetriebener funkgegesteuerter Mechanismus parallel auf den Handauslösegriff der Entfaltungsvorrichtung des Reserveschirmes wirkt. Dieser Tatechanismus kann dabei beispielsweise auf eine im Ruhezustand mechanisch blockierte vorgespannte Spiral-, Dreh-, Zug- oder Druckfeder entblockierend einwirken. Die Entblockierung kann elektrisch durch ein batteriebetriebenes System in Form einer Winde, eines Linear-oder Drehmagneten erfolgen.To trigger the reserve screen it is proposed that a pressurized gas - or battery-operated radio-controlled mechanism parallel to the hand release handle the deployment device of the reserve parachute acts. This tatechanism can in this case, for example, on a pretensioned one that is mechanically blocked in the idle state Spiral, torsion, tension or compression spring have a unblocking effect. The unblocking can be electrically powered by a battery-powered system in the form of a winch, a Linear or rotary magnets are made.
Weitere Möglichkeiten der Entblockierung bestehen darin einen zur Federblockierung vorgesehenen brenn-oder schmelzbaren Faden bzw. Draht durch Funkfernsteuerung zum Schmelzen zu bringen.Other ways of unblocking are to Spring blocking provided combustible or fusible thread or wire by radio remote control to melt.
Desweiteren kann die Entblockierung auch durch funkferngesteuerte pneuatische Kolbensysteme bzw.Furthermore, the unblocking can also be done by radio remote control pneumatic piston systems or
pyrotechnische Systeme erfolgen, die unter Umständen die Auslösung des Reserveschirmes unmittelbar bewirken.Pyrotechnic systems are carried out, which may trigger the trigger of the reserve parachute immediately.
