Abstract

This sail has been developed in order to obtain high efficiency with regard to speed and also to reduce the holding force to be applied. At the same time, good and easy handling is provided due to the short length of the wishbone boom.

Description

Beschreibung: Segelschnitt und ProfilDescription: Sail cut and profile

Die Erfindung betrifft Segelschnitt und Segelprofil.The invention relates to sail cut and sail profile.

Der Segelschnitt folgert aus dem Problem bei einer Rigglänge von 1,80 m bis 2,00 m eine Segelfläche von 5,5 qm bis 6,0 qm zu erreichen. Das Resultat ist ein hochausgeschn nes Achterliek mit einem Randbogen.The sail cut follows from the problem with a rig length of 1.80 m to 2.00 m to achieve a sail area of 5.5 square meters to 6.0 square meters. The result is a high-cut leech with an arched edge.

Um das Flattern bei einem großen Randbogen zu vermeiden ist es notwendig, eine Achterliekkonstruction zu erstellen. Dieses wurde ereicht durch 4 Aluminium Rohre als Segellatten und einbringen einer Achterlieksehne, die durch eine Achterliekspannsehne aktiviert wird. Siehe Fig. 1.In order to avoid fluttering with a large edge curve, it is necessary to to create a leech construction. This was achieved by 4 aluminum Pipes as battens and a leech tendon inserted through a leech tendon is activated. See Fig. 1.

Die Erfindung betrifft weiterhin ein-neues Segelprofil, das die Aufgabe hat, den Differenzluftdruck, der bei Aerodynamischen Profilen erforderlich ist, im vorderen Bereich des Segels, also in Mastnahe, zu erzeugen. S. Fig. 2.The invention also relates to a new sail profile that has the task has, the differential air pressure that is required for aerodynamic profiles, in the front area of the sail, i.e. near the mast. See Fig. 2.

Dadurch wird die Schubkraft, die durch den Differenzluftdruck entsteht, zum größten Teil direkt auf den Mast und durch ihn auf das Surfbrett übertragen.As a result, the thrust created by the differential air pressure for the most part transferred directly to the mast and through it to the surfboard.

Dieses bedeutet gleichzeitig eine Verringerung der Querkräfte und dadurch resultierend, eine erringerung der Haltekräfte des Fahrers.This also means a reduction in the lateral forces and as a result, a reduction in the driver's holding forces.

Bei herkömmlichen Segeln, die eine Rigglänge bis zu 2,60 m und eine symetrische Profilbiegelinie aufweisen, sind die Haltekräfte höher.With conventional sails that have a rig length of up to 2.60 m and a have a symmetrical profile bending line, the holding forces are higher.

Dieses Segelprofil weist im Gegensatz zu normal gebräuchlichen symetrischen Segelprofilen ein asymetrisches Profil auf. S. Fig. 2.This sail profile shows in contrast to the normally used symmetrical Sail profiles have an asymmetrical profile. See Fig. 2.

Dieses Segel zeichnet sich durch verschiedene Punkte aus.This sail is characterized by various points.

1. Dieses Erfindung ist dadurch gekennzeichnet, daß en großer Durchsatz, max. 25 cm, am Mast vorhanden ist.1. This invention is characterized in that a large throughput, max. 25 cm, is available on the mast.

S. Fig. 2. Item I 2. Diese Erfindung ist dadurch gekennzeichnet, daß die auslaufende Fläche zum Achterliek gerade verläuft. S. Figur.See Fig. 2. Item I 2. This invention is characterized in that the outgoing area to the leech is straight. S. figure.

Item II.Item II.

3. Diese Erfindung ist gekennzeichnet durch ein hochgeschnittenes Achterliek mit Randbogen. Siehe Fig. 1 Item 1.3. This invention is characterized by a high cut Leech with arched edge. See Fig. 1, Item 1.

4. Diese Erfindung ist'gekennzeichnet durch eine Achterliekspannung. 5. Fig.1 Item II.4. This invention is characterized by a leech tension. 5. Fig. 1 Item II.
