Abstract

The inbuilt ejector seats are ejected when the rotor blades are separated from the main rotor by in-blade charges triggered on seat release. The charges are installed in cavities in the blades and resist both pressure and tension. The explosive charges can also be mounted on the joints of the rotor blades.

Description

Bei strahlgetriebenen militärischen Luftfahrzeugen werden Schleudersitze zur Rettung der Besatzung in Notsituationen bereits seit Jahren eingesetzt. Hubschraubern wird diese Möglichkeit zur Bewahrung von Menschenleben bisher verwehrt, da eine Verwendung von Schleudersitzen durch die den Aufstieg der Sitze unmöglich machenden Rotorblätter des Hauptrotors verhindert wird.In jet-powered military aircraft, ejection seats are used to save the Crew used in emergency situations for years. Helicopters will Possibility of preserving human life has so far been denied because of use of Ejection seats due to the rotor blades of the Main rotor is prevented.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, den Aufstieg der Schleudersitze in Hubschraubern zu ermöglichen und die Sicherheit der zivilen und militärischen Luftfahrt zu erhöhen.The invention specified in claim 1 is based on the problem, the rise to allow the ejection seats in helicopters and the security of civil and increase military aviation.

Dieses Problem wird durch das im Patentanspruch 1 aufgeführte Rettungssystem gelöst.This problem is solved by the rescue system listed in claim 1.

Der mit der Erfindung erzielte Vorteil liegt hauptsächlich darin, daß die Rotorblätter im Notfall (gekoppelt mit der Auslösung des Schleudersitzes) abgesprengt werden und so der freie Aufstieg des Schleudersitzes ermöglicht wird. Dieser kann dann konventionell Aufsteigen und den/die Piloten an einem Fallschirm sicher zu Boden bringen.The advantage achieved with the invention is mainly that the rotor blades in Emergency (coupled with the release of the ejection seat) can be blown up and so the free ascent of the ejection seat is made possible. This can then be conventional Ascend and safely bring the pilot (s) to the ground on a parachute.

Eine weitere Ausführungsmöglichkeit ist in Patentanspruch 2 und 3 angegeben. Diese erlauben eine Anpassung an verschiedene Haupt-Rotortypen.Another possible embodiment is specified in claims 2 and 3. This allow adaptation to different main rotor types.

Ein Ausführungsbeispiel der Erfindung ist in der Abbildung beschrieben und wird im folgenden näher beschrieben.An embodiment of the invention is described in the figure and is in following described in more detail.

Claims (3)

1. Rettungssystem für Hubschrauber-Besatzungen mit Abtrennung der Haupt-Rotorblätter, dadurch gekennzeichnet, daß der Abschuß der zum System gehörenden Schleudersitze durch die Abtrennung der Haupt-Rotorblätter, hervorgerufen durch (gekoppelt an die Auslösung der Schleudersitze) gezündete Sprengsätze in den einzelnen Rotorblättern die die Rotorblätter vom Hauptrotor trennen und dadurch die Flugbahn der Schleudersitze vom Hindernis befreien, erst ermöglicht wird.1. Rescue system for helicopter crews with separation of the main rotor blades, characterized in that the firing of the ejection seats belonging to the system by the separation of the main rotor blades, caused by (coupled to the triggering of the ejection seats) detonated explosive devices in the individual rotor blades separate the rotor blades from the main rotor and thereby free the trajectory of the ejection seats from the obstacle. 2. Rettungssystem für Hubschrauber-Besatzungen mit Abtrennung der Haupt-Rotorblätter nach Patentanspruch 1, dadurch gekennzeichnet, daß die Rotorblätter durch in die Hohlräume des jeweiligen Rotorblatts eingelassenen stabilen (Zug- und Druckstabilen) Sprengsatz abgetrennt werden.2. Rescue system for helicopter crews with separation of the main rotor blades according to claim 1, characterized, that the rotor blades by embedded in the cavities of the respective rotor blade stable (tensile and pressure stable) explosive device can be separated. 3. Rettungssystem für Hubschrauber-Besatzungen mit Abtrennung der Haupt-Rotorblätter nach Patentanspruch 1, dadurch gekennzeichnet, daß die Rotorblätter durch an den Gelenken der Haupt-Rotorblätterbefestigung an­ gebrachten stabilen (Zug- und Druckstabilen) Sprengsatz abgetrennt werden.3. Rescue system for helicopter crews with separation of the main rotor blades according to claim 1, characterized, that the rotor blades through on the joints of the main rotor blade attachment brought stable (tensile and pressure stable) explosive device are separated.
