Description
Profilsegel Seit Bekanntwerden der günstigen Auftriebs- und Widerstandsverhältnisse von Flugzeugprofilen ist wiederholt versucht worden, auch das Segel von Wasserfahrzeugen profilartig zu gestalten. Um die nötige Form und Starrheit der Segelfläche zu erreichen, wurde entweder anstatt einer Hülle aus Segeltuch eine solche aus Cellon oder Aluminium vorgeschlagen, oder die Segeltuchhülle wurde durch einen Kopf aus starrem Material (Holz), der den Mast umfaßte, mit anschließenden, in bestimmten Abständen angeordneten, horizontalen, biegsamen Latten versteift. Die Nachteile dieser Konstruktion liegen vor allem im hohen Gewicht der so gebauten Profile, das auch dann in Erscheinung tritt, wenn nur der vordere Teil als Profil, der hintere Teil aber als normales Segel ausgebildet wird. Außerdem kann der Bruch einzelner Latten leicht eine Zerstörung des ganzen Profils zur Folge haben. Drittens ergeben sich beim Reffen eines solchen Profils Schwierigkeiten, so daß es bis heute praktisch nicht brauchbar ist.Profile sails Ever since the favorable buoyancy and drag ratios became known of aircraft profiles have repeatedly been tried, including the sails of watercraft to design profile-like. To achieve the necessary shape and rigidity of the sail area, Instead of a canvas cover, one made of cellon or aluminum suggested, or the canvas cover was made by a head of rigid material (Wood), which encompassed the mast, with subsequent, spaced apart, stiffened horizontal, flexible slats. The disadvantages of this construction are especially in the high weight of the profiles built in this way, which is also evident occurs when only the front part as a profile, but the rear part as normal Sail is trained. In addition, the breakage of individual slats can easily cause destruction of the whole profile. Third, when reefing, there is such a thing Profil's difficulties, so that it is practically useless to this day.
Die genannten Nachteile werden durch die Erfindung beseitigt. Die Form des Segels wird hier durch im Innern der Hülle angebrachte, der Profilform angepaßte, aufblasbare Hohlkörper hergestellt. In den Zeichnungen sind einige Ausführungsbeispiele dargestellt, und zwar kann die Profilform entweder durch eine luftdichte Haut a erzielt werden, die durch innereVerspannungen b aus geeignetem Material, z. B. Leinwand, in der gewünschten Form gehalten wird (Abb. i bis 3), oder sie wird durch ein System von Schläuchen hergestellt, die entweder in senkrechter d (Abb. q. und 5) oder waagerechter Lage c (Abb. 6 bis 8) oder durch Verbindung beider Anordnungen e (Abb. g bis i i) das Skelett des Segels bilden, während eine Hülle aus Segelstoff f die Verkleidung des Skeletts a, b, c, d, e übernimmt.The disadvantages mentioned are eliminated by the invention. The shape of the sail is produced here by means of inflatable hollow bodies fitted inside the shell and adapted to the profile shape. In the drawings some exemplary embodiments are shown, namely the profile shape can either be achieved by an airtight skin a, which is secured by internal stresses b made of a suitable material, e.g. B. canvas, is held in the desired shape (Fig. I to 3), or it is produced by a system of tubes that are either in a vertical position d (Fig. Q. And 5) or in a horizontal position c (Fig. 6 to 8) or by connecting both arrangements e (Fig. G to ii) form the skeleton of the sail, while a cover made of sail fabric f takes on the cladding of the skeleton a, b, c, d, e.
Hieraus ergibt sich gegenüber den bekannten Profilsegeln ein geringeres Gewicht, eine gute Anpassungsfähigkeit in bezug auf günstige Ausnutzung des Windes durch Regeln des inneren überdrucks sowie ein einfaches Handhaben und Verkleinern der Segelfläche durch ganzes oder teilweises Entleeren des luftdichten Körpers.This results in less than the known profile sails Weight, good adaptability in terms of making good use of the wind by regulating the internal overpressure as well as simple handling and reduction the area of the sail by emptying the airtight body completely or partially.
