Description
Steilschrauber mit einem zugleich mit Fallschirm ausschleuderbaren Sitz Es ist bekannt, in Luftfahrzeugen Sitze für die Besatzung vorzusehen, die im Falle der Gefahr zusammen mit der darauf sitzenden Person aus dem Luftfahrzeug herausgeschleudert werden können. Dabei ist entweder der Sitz mit einem Fallschirm versehen, .der groß genug bemessen ist, um Sitz und Insassen zusammen mit genügend geringer Sinkgeschwindigkeit zu Boden gelangen zu lassen, oder es ist möglich, daß sich der Insasse, der mit einem normalen Personenfallschirm ausgerüstet ist, von dem Sitz befreien kann, sobald er sich außerhalb des Luftfahrzeuges befindet.Steep screwdriver with a parachute that can be ejected at the same time Seat It is known to provide seats for the crew in aircraft, which are im In the event of danger, thrown out of the aircraft together with the person sitting on it can be. Either the seat is fitted with a parachute, the big one is sized enough to seat and occupant together with a sufficiently slow rate of descent to get to the ground, or it is possible that the inmate who is with is equipped with a normal personal parachute from which the seat can be released as soon as he is outside the aircraft.
Die Richtung, in der der Sitz herausgeschleudert wird, ist dabei zweckmäßig so zu wählen, daß während des Ausschleuderns und danach eine Berührung des Sitzes oder des Insassen mit Teilen -des Luftfahrzeuges ausgeschlossen ist.The direction in which the seat is thrown out is useful to be selected in such a way that the seat is touched during the ejection and afterwards or the occupant with parts of the aircraft is excluded.
Diese Forderung ist im allgemeinen bei normalen Drachenflugzeugen leicht zu» erfüllen, jedoch nicht bei Steilschraubern. Wenn z. B. das Ausschleudern bei Hubschraubereinstellung der Rotorblätter erfolgt, so besteht die Gefahr, daß der Sitz vor Entfaltung des Fallschirmes in den Drehkreis der Rotoren zurückfällt, besonders wenn der Steilschrauber keine Vorwärtsgeschwindigkeit hat, z. B. beim Schweben am Ort.This requirement is common to normal hang gliders easy to »meet, but not with steep screwdrivers. If z. B. ejection takes place in the helicopter setting of the rotor blades, there is a risk that the seat falls back into the turning circle of the rotors before the parachute unfolds, especially when the screwdriver has no forward speed, e.g. B. at Floating in place.
Der Erfindung unterliegt die Aufgabe, um diese Gefahr weitmöglichst zu vermindern, im Augenblick des Ausschleuderns des Sitzes die Sinkgeschwindigkeit des Steilschraubers so groß wie möglich zu machen.The invention is based on the task of avoiding this risk as much as possible to reduce the rate of descent at the moment the seat is thrown out of the screwdriver as large as possible.
Die Erfindung löst diese Aufgabe dadurch, daß mit der Vorrichtung, die das Ausschleudern des Sitzes bewirkt, ein Verstellglied zwangsläufig gekuppelt wird, das die Umschaltung der Rotorblätter mindestens auf Tragschraubereinstellung oder sogar darüber hinaus bis auf einen stark negativen Einstellwirkel bewirkt.The invention solves this problem in that with the device, which causes the seat to be ejected, an adjusting member is necessarily coupled that the switching of the rotor blades at least to gyroplane setting or even beyond that, except for a strongly negative setting effect.
«.'eitere Lösungsmöglichkeiten für die gestellte Aufgabe bestehen darin, daß mit dem Aasschleudern des Sitzes z. B. die Zündung des Antriebsmotors unterbrochen, die Gaszufuhr abgesperrt oder die Kupplung zwischen Motor und Steilschraube getrennt wird, wenn, wie es bei brauchbaren Steilschraubern üblich ist, jede dieser zuletzt angeführten, an sich bekannten Betriebszustandsänderungen, die ja jeweils eine Unterbrechung der Leistungsabgabe vom Motor an den oder die Rotoren bedeuten, ohne weiteres eine selbsttätige Umschaltung der Rotorblätter auf Tragschraubereinstellung zur Folge hat.There are other possible solutions for the task at hand in that with the carrion of the seat z. B. the ignition of Drive motor interrupted, the gas supply shut off or the coupling between Motor and steep screw is separated if, as is the case with usable steep screwdrivers It is customary to carry out each of these last-mentioned, known operating status changes, each of which is an interruption of the power output from the engine to the or the Rotors mean, without further ado, an automatic switchover of the rotor blades Gyroplane adjustment.
