Description
Be s ehre ibungHonor
Es ist bekannt, daß ein Fallschirm wenn er gezogen wird, Auftrieb erzeugt und ein beachtliches Gewicht heben kann.It is known that a parachute, when pulled, generates lift and can lift considerable weight.
Der Auftrieb wird durch die Kappenform erzeugt und ein Vortrieb durch Öffnungen in der Fallschirmkappe.The lift is generated by the shape of the canopy and propulsion through openings in the parachute canopy.
Die Basiserfindungen hierzu wurden in den 60er Jahren dieses Jahrhunderts gemacht.The basic inventions for this were made in the 1960s of this century.
Zu Zugzwecken im Wind eignet sich dieses Prinzip jedoch schlecht, weil eine Steuerungsmöglichkeit nicht gegebenHowever, this principle is not suitable for pulling in the wind because there is no possibility of control
Eine andere Möglichkeit um Zugkraft einzusetzen ist die Verwendung von GIeitschirmen oder Drachen, die mit Luftkammersystemen und entsprechenden Profilen ausgestattet sind.Another way to use traction is to use paragliders or kites that are equipped with air chamber systems and corresponding profiles.
derartige Gebilde sind sehr aufwendig aufgebaut und bei Abstürzen gefährdet, da im Inneren durch Druckerhöhungen Kammerwände platzen können.Such structures are very complex and are at risk in the event of a crash, as the chamber walls can burst due to increases in pressure inside.
Die vorliegende Erfindung benutzt das Wirkungsprinzip der Fallschirmdrachen, das um die Lenkbarkeit mit zwei Leinen erweitert wird.The present invention uses the operating principle of parachute kites, which is extended to include controllability with two lines.
Durch den einfachen Aufbau reduziert sich der Materialverbrauch und die Arbeitszeit für die Produktion erheblich. Da keine keine Kammern vorhanden sind, ist auch eine Beschädigungsgefahr reduziert.The simple structure reduces material consumption and production time considerably. Since there are no chambers, the risk of damage is also reduced.

Beschreibung der FigurenDescription of the characters
Fig.l zeigt die Ansicht des Segels von der Seite der Zugkraftabnahmen. Die Teilprofile (8) bzw. Abnäher (8) sind als Option gestrichelt und nur einmal mit {8) gekennzeichnet.Fig.l shows the view of the sail from the side of the traction force reductions. The partial profiles (8) or darts (8) are dashed as an option and only marked once with {8).
Ebenso gestrichelt ist die Option "Zugkraftabnahme in der Segelfläche" (7). Strichpunktiert ist ein Profil bzw. geteiltes Profil (5/9) auf der Segelfläche eingezeichnet.The option "Tension force reduction in the sail area" (7) is also shown in dashed lines. A profile or split profile (5/9) is shown in dashed lines on the sail area.
Fig.2 zeigt die Seitenansicht des Segels. Gestrichelt ist die "Zugkraftabnahme in der Segelfläche" (7) und die entstehende Eindrückung der Segelfläche (1). Strichpunktiert ist ein geteiltes Profil (9) dargestellt.Fig.2 shows the side view of the sail. The dashed line shows the "reduction in tensile force in the sail area" (7) and the resulting indentation of the sail area (1). A split profile (9) is shown in dash-dot lines.
Fig.3 zeigt die Vorderansicht des Segels, Gestrichelt sind die Teilprofile (8) bzw. Abnäher (8), die "Zugkraftabnahme in der Segelfläche" (7), die unsichtbaren Kanten der Segelöffnungen (4) und die Eindrückung der Sege-l fläche . Strichpunktiert ist ein Profil bzw. geteiltes Profil (5/9) eingezeichnet.Fig.3 shows the front view of the sail. The partial profiles (8) or darts (8), the "traction force reduction in the sail area" (7), the invisible edges of the sail openings (4) and the indentation of the sail area are shown in dashed lines. A profile or divided profile (5/9) is shown in dash-dotted lines.
