Abstract

The sail is intended for a sailing boat. It is formed as an air-impermeable hollow flexible member which, when pressurised, forms an external aerofoil profile. In the rest position, the profile may be symmetrical. The aerofoil profil may be obtained by distance pieces contained in the hollow space. The hollow space may be partitioned into a number of chambers. It may be provided with one or more outlets permitting rapid deflation. The low and/or high pressure side may be provided with form strips extending in the direction of air flow.

Description

Profil -SegelProfile sail

Beschreibung: Segel dienen dem Antrieb von Wasser- und Landfahrzeugen. Sie sollen bei Anblasung mittels ihrer gewölbten Flache bei elnrachem tuSbau QuerKratte zur çortbewcgung von Fahrzeugen bei geringern Widerstand erzeugen.Description: Sails are used to propel watercraft and land vehicles. When blowing on, they should use their curved surface at elnrachem tuSbau QuerKratte for moving vehicles with less resistance.

Es ist bekannt, daß ein aerodynamisches Vollprofil eine wesentlich höhere Querkraft bei geringerem Widerstand liefert als eine einfache gewölbte Fläche. So wurden schon Versuche unternommen an Stelle eines herkömmlichen Stoffsegels ein profiliertes sog.It is known that a full aerodynamic profile is essential delivers higher transverse force with less resistance than a simple curved surface. Attempts have already been made to replace a conventional cloth sail with one profiled so-called

Starrsegel zu verwenden. Erwartungsgemäß brachte dieses in Gemischtbauweise wie bei einem Segelflugzeug aufgebaute Starrsegel sehr gute Leistungen und Pigenschaften.Use rigid sail. As expected, this brought in a mixed construction Rigid sails constructed like a glider have very good performance and properties.

Die Nachteile des Starrsegels hinsichtlich Gewicht, Raumbedarf und Handhabung konnten jedoch auch bei Unterteilung des Starrsegels in mehrere Einzelstücke gemäß OS 23 56 426 nicht grundsätzlich vermieden werden Der Erfindung liegt die Aufgabe zugrunde, die Vorteile des leistungsfähigen Starrsegels mit dem geringen Raumbedarf und der einfachen Handhabung des Stoffsegels bei vergleichbarem Gewicht zu verbinden.The disadvantages of the rigid sail in terms of weight, space requirements and However, handling was also possible when the rigid sail was divided into several individual pieces according to OS 23 56 426 can not be avoided in principle Task based on the advantages of the powerful fixed sail with the low Space requirements and the easy handling of the fabric sail with a comparable weight connect to.

Zur Lösung dieser Aufgabe soll das Segel gemäß dem kennzeichnenden Teil des A. 1 als Schlauch ausgebildet sein, dessen luftdichte Hülle durch den unter Druck gesetzten Hohlraum die Form eines aerodynamischen Profils erhält.To solve this problem, the sail should according to the characteristic Part of the A. 1 be designed as a tube, the airtight envelope through the under Pressurized cavity is given the shape of an aerodynamic profile.

Nach weiteren Kennzeichen der Erfindung gemäß den Unteransprüchen soll das Profil in Ruhestellung symmetrisch sein, in den Hohlraum können die aerodynamische Form erhaltende Ahstandsstücke eingearbeitet sein, der Hohlraum kann auch aus mehreren Kammern bestehen, er kann auch einen oder mehrere Schnellablässe besitzen.According to further characteristics of the invention according to the subclaims If the profile should be symmetrical in the rest position, the aerodynamic one can be inserted into the cavity Shape-preserving Ahstandsstück be incorporated, the cavity can also consist of several Chambers exist, it can also have one or more rapid drains.

Schließlich können an der Saug- und/oder Druckseite etwa in Anströmrichtung verlaufende Formgebungsleisten mit der Hülle verbunden sein.Finally, on the suction and / or pressure side, approximately in the direction of flow extending shaping strips be connected to the shell.

Vorteile der Erfindung bestehan darin, daß Befestigung und Anlenkung am Mast wie bei einem normalen Segel erfolgen können.Advantages of the invention consist in the fact that fastening and articulation can be done on the mast like a normal sail.

Darüber hinaus wäre auch eine in das Segel einbezogene oder am Mast befestigte und mit dem Segel bewegliche Mastverkleidung oder ein profilierter mit dem Segel schwenkbarer Mast möglich.In addition, one would also be included in the sail or on the mast fixed and movable with the sail mast cladding or a profiled one with The mast can be swiveled to the side of the sail.

Ein weiterer Vorteil ist darin zu sehen, daß die größeren Querkräfte des Profilsegels kleinere Segelflächen, insbesondere kleinere Segelhöhen ermöglichen, die wiederum kleinere Schwerter gestatten, wichtig insbesondere für Schlauchbeote Hinzu kommt, daß das Stel durch Schnellablässe leicht gerefft und im Gegensatz zum profilierten Starrsegel problemlos transportiert wersen kann, ebenfalls wichtig inebesondere im Zusammenhang mit Schlauchbooten.Another advantage is that the larger transverse forces of the profile sail enable smaller sail areas, in particular smaller sail heights, which in turn allow smaller swords, especially important for inflatable boats In addition, the stel is easily reefed by rapid drainage and in contrast to the profiled rigid sail can be transported without any problems, also important especially in connection with rubber dinghies.
