When opening the parachute from high-speed airplanes or missiles, a high shock load occurs on the inside as well as on the outside of the parachute canopy. In order to reduce this shock load, adhesive connections were made. If necessary, the various damping devices are already in front of the applied adhesive through the application

The parts 3 of the parachute canopy 4 can both be arranged in the edge of the parachute canopy. This annular, irregular arrangement as well as the symmetrical edge zone of the parachute canopy is subject to a very high load and a large amount of resources, such as eyelets, reefing lines and are required
Reefing line brakes, which is also prone to failure.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Dämpfung der Stoßbelastung beim öffnen
eines Fallschirmes derart auszubilden, daß zusätzlicher
Aufwand, das Gewicht und das Volumen gegenüber bekannten Dämpfungseinrichtungen erheblich reduziert bo schließen, kann an den Befestigungen 5 eine"verstärsmdkung
der Fallschirmkappe vorgesehen sein.The invention is based on the object of providing a device for damping the shock load when opening
to train a parachute in such a way that additional
Effort, the weight and volume compared with known dampers significantly reduced bo conclude a "verstär sm dkung the canopy can be provided on the fixtures. 5
Für einen Fallschirm bekannter Art ist diese Aufgabe For a known type of parachute, this task is
erfindungsgemäß dadurch gelöst, daß auf der gesamten Hierzu 1 Blatt Zeichnungenaccording to the invention achieved in that 1 sheet of drawings on the entire for this purpose
Fallschirmkappe verteilt, unter Bildung von im Luft- Parachute canopy, with the formation of airborne
strom aufreißbaren Taschen, Teile der Kappe aneinan- b5 der befestigt sind. Beim Absetzen einer Last aus einem schnell fliegenden Flugzeug, einem Flugkörper oder einer Bombe bietet ein derartig ausgebildeter Fallschirm Ordnung der Befestigungen 5 miteinandner verbunden sein. Eine weitgehend symmetrische Anordnung der Befestigung ergibt sich zwangsweise, wenn Teile 3a bzw. 3b eines Fallschirmes die Gestalt der schraffierten Flächen der in den Fig.2 und 3 gezeigten Fallschirme la und \b haben, die im übrigen mit dem beschriebenen Ausführungsbeispiel übereinstimmen. Um ein Einreißen der Fallschirmkappe beim Öffnungsvorgang auszu-current tear-open pockets, parts of the cap are attached to one another. When a load from a fast-flying airplane, a missile or a bomb is deposited, a parachute designed in this way offers the possibility of the fastenings 5 being connected to one another. A largely symmetrical arrangement of the attachment results inevitably when parts 3a and 3b of a parachute have the shape of the hatched areas of the parachutes la and \ b shown in FIGS. 2 and 3, which otherwise coincide with the exemplary embodiment described. In order to prevent the parachute canopy from tearing during the opening process.
