Abstract

The safety device for a helicopter (1) comprises a brake parachute (5) which is stowed packaged in a storage space (4) which engages on the rotor shaft (3) of the main rotor (2) and can be activated by the pilot, by a propulsion charge, in the event of a risk of an accident, so that the brake parachute (5), which engages on the rotor shaft (3) via a freewheeling device (6) makes an emergency landing of the helicopter (1) possible. <IMAGE>

Description

Die Erfindung betrifft eine Sicherheitseinrichtung für Dreh­ flügelflugzeuge, insbesondere für Hubschrauber nach dem Ober­ begriff des Hauptanspruches.The invention relates to a safety device for rotation wing aircraft, in particular for helicopters upwards concept of the main claim.

Unter dem Sammelbegriff Drehflügelflugzeuge sind Hubschrauber, Tragschrauber und Flugschrauber zu verstehen, die keine starren Tragflächen aufweisen und nur durch umlaufende Rotorflügel in der Luft gehalten werden.The general term rotary wing aircraft includes helicopters, To understand gyrocopters and aircraft screwdrivers that do not stare Have wings and only by rotating rotor blades in to be kept in the air.

Bei allen anerkannten Vorteilen dieser Drehflügelflugzeuge gegenüber üblichen Flugzeugen mit starren Tragflächen haben erstere den Nachteil, daß bei Ausfall des Rotorantriebes ein schneller und totaler Absturz eintritt, der in der Regel auch zum Tod der Flugzeuginsassen führt. Gleitlandungen, Bruch­ landungen oder Notlandungen wie sie bei herkömmlichen Flugzeugen mit Überlebenschance für die Insassen möglich sind, sind bei solchen Drehflügelflugzeugen praktisch ausgeschlossen.With all the recognized advantages of these rotary wing aircraft compared to conventional aircraft with rigid wings the former has the disadvantage that a failure of the rotor drive faster and total crash occurs, which usually too leads to the death of the aircraft occupants. Glide landings, break Landings or emergency landings like those of conventional aircraft with a chance of survival for the occupants are at such rotary wing aircraft practically excluded.

Der Erfindung liegt daher die Aufgabe zugrunde, mit einfachen Mitteln die Voraussetzung für eine Notlandung derartiger Dreh­ flügelflugzeuge bei Ausfall des Hauptrotors bzw. Verlust der Auftriebskraft zu schaffen.The invention is therefore based on the object with simple Means the prerequisite for an emergency landing of such rotation wing aircraft in the event of failure of the main rotor or loss of Creating buoyancy.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß min­ destens ein Bremsfallschirm an der Rotorachse des Hauptrotors angreift, der in einem Depot an der Rotorachse verpackt einge­ lagert und im Falle der Absturzgefahr aktivierbar ist. Die Tragkraft des Bremsfallschirmes ist der Größe und dem Gesamt­ gewicht des Drehflügelflugzeuges angepaßt. Vorzugsweise ist der Bremsfallschirm durch einen Treibsatz aus dem Depot kata­ pultierbar, um eine schnelle Entfaltung des Bremsfallschirmes auch bei relativ niedriger Flughöhe bzw. Absturzhöhe aktivieren zu können, so daß auch für solche Gefahrensituationen die Chance einer Notlandung besteht. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.This object is achieved in that min a brake parachute on the rotor axis of the main rotor attacks, which is packed in a depot on the rotor axis stored and can be activated in the event of a risk of falling. The The load capacity of the brake parachute is the size and the total adjusted weight of the rotary wing aircraft. Preferably the brake parachute by a propellant from the depot kata pultable for a quick deployment of the brake parachute Activate even at a relatively low flight altitude or fall height to be able, so that the chance for such dangerous situations  there is an emergency landing. Advantageous further developments are in specified in the subclaims.

Der Erfindungsgedanke ist in einem Ausführungsbeispiel anhand der beiliegenden Zeichnung näher erläutert.The inventive concept is based on an exemplary embodiment the accompanying drawing explained.

Fig. 2 in schematischer Ansicht das Fallschirmdepot an der verlängerten Rotorachse. Fig. 2 is a schematic view of the parachute depot on the extended rotor axis.

Der Hubschrauber 1 weist in direkter Verlängerung seiner Rotor­ achse 3 seines Hauptrotors 2 ein Depot 4 für einen verpackten Bremsfallschirm 5 auf, dessen Tragseile 5′ mit der Rotorachse 3 unter Zwischenschaltung eines Freilaufes 6 fest verbunden sind. Die Tragkraft des Bremsfallschirmes 5 ist nach dem Gesamtgewicht des Hubschraubers derart angepaßt, daß bei Aktivierung des Bremsfallschirmes 5 eine Notlandung möglich bzw. ein Absturz verhindert werden kann.The helicopter 1 has in direct extension of its rotor axis 3 of its main rotor 2, a depot 4 for a packaged brake parachute 5 , the supporting cables 5 'with the rotor axis 3 with the interposition of a freewheel 6 are firmly connected. The supporting force of the braking parachute 5 is adapted according to the total weight of the helicopter such that an emergency landing possible or a crash can be prevented upon activation of the braking parachute. 5

Die Aktivierung des verpackten Bremsfallschirmes 5 erfolgt vorzugsweise durch einen Treibsatz 7 am Depot 4, mit dem der Bremsfallschirm 5 aus dem Depot 4 herauskatapultiert werden kann. Die Auslösung des Treibsatzes 7 erfolgt z. B. drahtlos durch den Hubschrauberpiloten bei Absturzgefahr.The packaged brake parachute 5 is preferably activated by a propellant 7 at the depot 4 , with which the brake parachute 5 can be catapulted out of the depot 4 . The triggering of the propellant charge 7 takes place, for. B. wirelessly by the helicopter pilot when there is a risk of falling.
