Abstract

A parachute system is disclosed for especially ballistically deployed systems. Said parachute system comprises an unopened parachute (20), the canopy (1) of which is enclosed by a packsack (11) that has predetermined breaking points (12) in the bottom zone and a cable connection (13) or the like to the functional support (5) at the top end. When the cable connection (13) acts on the packsack (11), the latter is separated from the functional support (5) at the predetermined breaking points, and the parachute (20) is unfolded by raising the canopy (1). A stabilizing net (2) is incorporated into the parachute (20). The canopy (1), including the stabilizing net (2) and the strings (3), is connected to the functional support (5) via a stable connection (4) which comprises a steel cable lock (6), a brake (7) for the steel cable lock (6), and a steel cable (8).

Description

BESCHREIBUNG DESCRIPTION
Fallschirmsystem für insbesondere ballistisch ausgebrachte SystemeParachute system for especially ballistic deployed systems
Aus dem Stand der Technik sind Fallschirmsysteme beispielsweise zum Ausbringen von Leuchtmunitionen, projektilbildenden Ladungen und anderen Sondermunitionen bekannt und dienen zur Reduzierung der Sinkgeschwindigkeit bei Drall- (Artillerie-), pfeilstabilisierten- (Mörser-) Geschossen und anderen ballistisch ausgebrachten Typmunitionen. Bisherige Fallschirmsysteme weisen dabei jedoch den Nachteil auf, dass das Öffnen des Fallschirmsystems nicht gleichmäßig reproduzierbar ist. Die dynamischen Öffnungsprozesse sind hochkomplex bedingt durch die bekannten Fallschirmsysteme wie Kreuzbalkenfallschirme sowie die klassischen Rundkappenfallschirme, eine entsprechende Fehleranfälligkeit ist gegeben, welche sich aus deren Anbindung an die Funktionseinheit, die beim dynamischen Öffnungsprozess das Öffnen der Fallschirmkappe vereitelt. Derartige Anbindungen sind beispielsweise Stahl oder Seile.From the state of the art, parachute systems are known, for example, for deploying light ammunition, projectile-forming charges and other special munitions, and are used to reduce the rate of sinking in swirl (artillery), arrow-stabilized (mortar) projectiles and other ballistically deployed type munitions. However, previous parachute systems have the disadvantage that the opening of the parachute system is not uniformly reproducible. The dynamic opening processes are highly complex due to the known parachute systems such as cross-beam parachutes and the classic round-cap parachutes, a corresponding error rate is given, resulting from their connection to the functional unit, which thwarts the opening of the parachute in the dynamic opening process. Such connections are for example steel or ropes.
Diese Unsicherheit des richtigen Öffnens erfordert eine hohe Montagequalität und -aufwand zur Sicherstellung des Öffnens. Als weiterhin nachteilig hat sich gezeigt, dass die Fallschirmseile beim Öffnen abreißen oder sich verwickeln können.This uncertainty of proper opening requires a high level of assembly quality and effort to ensure opening. As further disadvantageous it has been shown that the parachute ropes can tear off when opening or entangle.
Hier stellt sich die Erfindung die Aufgabe, die Funktionssicherheit insbesondere des Öffnungsvorganges bei Reduzierung des Montageaufwande zu erhöhen s.Here, the invention has the object to increase the reliability especially of the opening process with reduction of assembly costs s.
Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausführungen sind in den Unteransprüchen aufgeführt.The object is achieved by the features of claim 1. Advantageous embodiments are listed in the subclaims.
Der Erfindung liegt die Idee zugrunde, einen Fallschirmtyp zu verwenden, der eine mit einem Faserband verstärkte Fallschirmkappe aufweist und durch ein Netz bzw. Packsack zu einem Ballonschirm zusammengefasst wird. Die Fallschirmanbindung zeichnet sich dadurch aus, dass ein Faserband mit eingebrachten Stahlseilen eingebunden wird, das nur an der Anbindung fixiert ist und zum Fallschirm hin über Brücken gehalten wird. Durch diesen Aufbau wird in vorteilhafter Art und Weise nicht nur die Aufgabe gelöst, sondern es werden auch die Einzelkomponenten reduziert. Die Verwendung eines Packsackes mit Sollbruchstellen erlaubt es, auf bekannte komplexe Randkonstruktionen, wie Federsystem im Heckteil etc. zur Einleitung des Öffnens zu verzichtenThe invention is based on the idea to use a parachute type, which has a reinforced with a sliver parachute and is summarized by a network or pack sack to a balloon umbrella. The parachute connection is characterized by the fact that a sliver with incorporated steel cables is incorporated, which is fixed only at the connection and is held to the parachute over bridges. By this construction, not only the problem is solved in an advantageous manner, but it also reduces the individual components. The use of a pack sack with predetermined breaking points makes it possible to dispense with known complex edge structures, such as spring system in the tail section, etc. to initiate the opening
Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung bzw. der Aufbau näher erläutert werden. Es zeigt:Reference to an embodiment with drawing, the invention and the structure will be explained in more detail. It shows:
Fig. 1 einen noch ungeöffneten Fallschirm in Anwendung,1 shows a still unopened parachute in use,

Fig. 1 zeigt einen ungeöffneten Fallschirm 20, dessen Fallschirmkappe 1 (Fig. 2) von einem so genannten Packsack 11 in dieser Darstellung noch umschlossen wird. Am Packsack 1 befinden sich im unteren Bereich Sollbruchstellen 12, am oberen Ende eine Seil- Anbindung 13 oder ähnliches zum Zugträger, beispielsweise eine nicht näher dargestellte Haube des Funktionsträgers 5, wie beispielsweise Geschoss, Projektil etc:, eines insbesondere ballistisch verbrachten Systems (Fig. 2).Fig. 1 shows an unopened parachute 20, the parachute cap 1 (Fig. 2) is still enclosed by a so-called pack bag 11 in this illustration. At the bottom of the pack 1 are located at the bottom of predetermined breaking points 12, at the top of a cable connection 13 or the like to the train, for example, not shown hood of the function carrier 5, such as bullet, projectile etc, a particular ballistically spent system (Fig. 2).
Mit Wirkung durch die Seilanbindung 13 auf den Packsack 11 (beispielsweise Abtrennung der Haube) wird dieser an seinen Sollbruchstellen 12 vom System abgetrennt. Der Fallschirm 20 baut sich auf wie in Fig. 2 aufgezeigt, wobei sich die Fallschirmkappe 1 aufrichtet. Unterstützt wird dieses Aufbauen durch ein Stabilisierungsnetz 2. Im Stabilisierungsnetz 2 eingebunden sind Stabilisierungsbänder 3. Die Fallschirmkappe 1 mit Netz und Bänder 3 ist über eine stabile Anbindung mit dem Funktionsträger 5 verbunden.With effect by the cable connection 13 on the packing bag 11 (for example, separation of the hood) this is separated at its predetermined breaking points 12 from the system. The parachute 20 builds up as shown in Fig. 2, wherein the parachute cap 1 straightens. This construction is supported by a stabilization network 2. Stabilization bands 3 are integrated in the stabilization network 2. The parachute cap 1 with net and bands 3 is connected to the function carrier 5 via a stable connection.
Fig. 3 zeigt eine vergrößerte Darstellung der Anbindung 4, die eine Stahlseil- Arretierung 6 sowie eine Bremse 7 der Stahlseil -Arretierung 6 und ein Stahlseil 8 umfasst. Über eine Öse bzw. Schlaufe oder dergleichen erfolgt die Anbindung am Funktionsträger 5, der seinerseits eine Stahlseil- Arretierung 10 für das Stahlseil 8 aufweist. Fig. 3 shows an enlarged view of the connection 4, which comprises a steel cable lock 6 and a brake 7 of the steel cable -Arretierung 6 and a steel cable 8. Via an eyelet or loop or the like, the connection is made to the function carrier 5, which in turn has a steel cable lock 10 for the steel cable 8.
