Abstract

The paragliding, inflatable kite or steerable parachute is provided with ribs, and pivot points to which suspension lines (6) are mounted, where the bottom side is reinforced with foam. The ribs are made of foam. The suspension lines connecting points are connected on a profile rib (2) by reinforcement foam.

Description

ZusammenfassungSummary

Die Erfindung ermöglicht den Bau von Gleitschirmen, Fallschirmen und Lenkdrachen, bei denen lediglich zwei Leinenanlenkungen pro Profilrippe verwendet werden, ohne dass das Profil dadurch verformt wird.The invention allows the construction of paragliders, parachutes and kites, in which only two Leinenanlenkungen per tread rib are used without the profile is deformed thereby.

Einleitungintroduction

Gleitschirme, Fallschirme und Lenkdrachen mit Luftkammernbauweise werden heute in vielen Bereichen verwendet. Mit Gleitschirmen wird von Hängen und an der Winde gestartet und mit Hilfe von Thermik und Wind große Strecken zurückgelegt. Mit Fallschirmen wird aus größeren Fluggeräten abgesprungen und der Landeplatz zielgenau angeflogen. Lenkdrachen werden mit Surfbrettern, mit Kufen oder Rädern versehenen Fahrzeugen oder auch kleineren Schiffen als Zug-Gerät verwendet. Ihnen allen gemeinsam ist die einfache Bauweise aus fast luftdichtem Stoff, welcher das Gerät leicht, einfach herzustellen und kostengünstig macht. Die seit vielen Jahren bewährte Luftkammer-Bauweise wurde bis heute verfeinert und die Leistungsfähigkeit eines modernen Gleitschirmes erreicht fast die eines Hängegleiters. Bei den Gleitschirmen, Fallschirmen und Lenkdrachen ist einer der größten Leistungsbremsen der Widerstand der Leinen. Einerseits braucht man für eine möglichst hohe Profiltreue mindesten drei, normalerweise sogar vier Anlenkpunkte, anderseits bedarf es für weniger Luftwiderstand und mehr Gleitleistung so wenige Leinenmeter als möglich. Dieses Paradox wird von einigen Herstellern durch die Verwendung von Karbon-, PVC oder Fiberglas-Stäbchen umgangen, welche zur besseren Lastverteilung im die Profile eingebaut werden.Paragliders, parachutes and kites with air chamber construction are used in many areas today. Paragliders are started from slopes and at the winch and covered by thermals and wind. Parachutes take off from larger aircraft and the landing area is approached accurately. Stunt kites are used with surfboards, with skids or wheeled vehicles or smaller ships as a train device. Common to all of them is the simple construction of almost airtight material, which makes the device light, easy to manufacture and inexpensive. The tried and tested air chamber design has been refined to this day and the performance of a modern paraglider almost reaches that of a hang glider. Among the paragliders, parachutes and stunt kites, one of the biggest performance brakes is the resistance of the lines. On the one hand, you need at least three, usually even four points of articulation for the highest possible profile fidelity; on the other hand, you need as few line meters as possible for less air resistance and more glide performance. This paradox is bypassed by some manufacturers through the use of carbon, PVC or fiberglass rods, which are installed in the profiles for better load distribution.

Allerdings entspricht die Verwendung von starren Bauteilen nicht der FAI-Definition des Geitschirmes. Zudem sind starre Bauteile im Gleitschirm ein hohe Sicherheitsrisiko, da sich die starren Stäbchen bei großflächigem Einklappen in den Leinen verhängen und einen unkontrollierten Absturz verursachen können.However, the use of rigid components does not conform to the FAI definition of the screen. In addition, rigid components in the paraglider pose a high security risk, since the rigid rods impose in the lines when folded over a large area and can cause an uncontrolled crash.

Stand der TechnikState of the art

Aktuelle Gleitschirme, Lenkdrachen und Fallschirme bestehen aus mehreren Luftkammern 11 (auch Zellen 11 genannt), welche im aufgeblasenen Zustand zusammen die Form eines Tragflügels bilden (1). Aufgeblasen werden diese Zellen 11 entweder durch Öffnungen 15 an der Profilnase und/oder Öffnungen im Untersegel 13.Current paragliders, stunt kites and parachutes consist of several air chambers 11 (also cells 11 called), which together form the shape of a wing when inflated ( 1 ). These cells are inflated 11 either through openings 15 at the profile nose and / or openings in the lower sail 13 ,

Aktuelle Gleitschirme haben zwischen 3 und 4 Anlenkpunkte pro Profilrippe.Current paragliders have between 3 and 4 articulation points per tread rib.

Aufgabe der ErfindungObject of the invention

Die Erfindung betrifft einen Gleitschirm, Fallschirm oder Lenkdrachen, der die Form eines Tragflügels hat. Ziel ist es, eine möglichst hohe Profiltreue bei maximal reduziertem Fangleinenwiderstand zu erreichen, um eine hohe aerodynamische Güte zu erreichen und somit die Leistung und Stabilität zu verbessern.The invention relates to a paraglider, parachute or stunt kite, which has the shape of an airfoil. The aim is to achieve the highest possible profile fidelity with maximum reduced line resistance in order to achieve a high aerodynamic quality and thus to improve performance and stability.

Übliche Luftkammern 1 bestehen aus den Profilrippen 2, der Obersegelbahn 3 und der Untersegelbahn 4. Bei komplexeren Gleitschirmen können sich innerhalb einer Luftkammer auch zusätzliche diagonale Verspannungen in Form von Stoffbahnen oder Bändern befinden. Diese Luftkammern 1 werden durch die Eintrittsöffnungen 5 im Flug mit Luft gefüllt. An den Profilrippen sind die Fangleinen 6 befestigt. (1)Usual air chambers 1 consist of the tread ribs 2 , the Obersegelbahn 3 and the undersea track 4 , For more complex paragliders, additional diagonal strains in the form of panels or ribbons may also be present within an air chamber. These air chambers 1 be through the inlet openings 5 in flight filled with air. At the profile ribs are the suspension lines 6 attached. ( 1 )

Um die maximale Profiltreue mit nur zwei Fangleinenanlenkungen zu erreichen, wird ein Teil des Profils aus Schaumstoff gebaut. Da die Last pro Anlenkpunkt im Flug relativ gering ist – üblicherweise unter 10 Kg – kann ein sehr leichter, aber dennoch fester Schaumstoff verwendet werden. Die Dicke dieser Schaumstoffverstärkung kann je nach Bedarf zwischen 1 und 25 mm liegen.In order to achieve the maximum profile fidelity with only two mooring lines, a part of the profile is made of foam. Since the load per articulation point in flight is relatively low - usually below 10 kg - a very light, yet solid foam can be used. The thickness of this foam reinforcement can be between 1 and 25 mm as needed.

2 zeigt die herkömmliche Bauweise einer Profilrippe mit den Anlenkpunkten für die Leinen. 2 shows the conventional construction of a tread rib with the linkage points for the lines.

3 zeigt die in der Luft übliche Verformung des Profils unter Lastverteilung, zur besseren Veranschaulichung übertrieben dargestellt. 3 shows the usual in the air deformation of the profile under load distribution, exaggerated for clarity.

4, 4a, 4b zeigen die neue Bauweise der Profilrippen im Sinne der Erfindung. Im Unterschied zur in 2 dargestellten Bauweise ist die Lastverteilung dank des flexiblen Schaumstoffmateriales nun optimal. 4 . 4a . 4b show the new design of the profile ribs in the context of the invention. Unlike in 2 The design shown, the load distribution thanks to the flexible foam material is now optimal.

5 zeigt die Verformung einer Profilrippe unter Last mit der Bauweise im Sinne der Erfindung. 5 shows the deformation of a tread rib under load with the construction according to the invention.
