Abstract

The tipping wing (1,2) for wind-powered propulsion of vehicles, partic. watercraft, has an asymmetrical profile (X) and is pivoted horizontally along its longitudinal axis (a - b). When going about, it is inverted to maintain aerodynamic effectiveness. The wing may be foldable or telescopic, the lower half being folded/retracted while the upper is fully spread. One craft may carry several such units, in tandem and/or in parallel. Either pivot point (a,b) may embody means - mechanical, hydraulic, electrical or any of these in combination - for adjusting the wind angle-of-attack.

Description

Kippflügel als Tilt vane as

Windantrieb von Fahrzeugen Die Erfindung betrifft einen Kippflügel als Windantrieb von Fahrzeugen insbesondere von Wasserfahrzeugen. Wind drive for vehicles The invention relates to a tilt vane as a wind drive for vehicles, in particular for watercraft.

Zweck des Kippflügels ist der Einsatz starrer, asymmetrischer Profile als Windantrieb.The purpose of the bottom-hung sash is to use rigid, asymmetrical profiles as a wind drive.

Es existieren viele Variationen und Kombinationen von Versuchen, ein Fahrzeug mit Windkraft durch Einsatz starrer Flügel anzutreiben. Alle sind jedoch aus ökonomischer Sicht zu keinem Ergebnis gekommen, da auf Grund der Systeme entweder symmetrische Profile oder Flügel mit komplizierten und aufwendigen Steuer- und Verstellsystemen angewandt werden mußten.There are many variations and combinations of attempts at one Propel the vehicle with wind power through the use of rigid blades. However, all are From an economic point of view, there was no result, either because of the systems symmetrical profiles or wings with complicated and expensive control and adjustment systems had to be applied.

Dieser Erfindung liegt die Aufgabe zugrunde, ein asymmetrisches Profil (größte Vortriebsausbeute) auf Kursen am Wind ohne große Komplikation sowohl auf Backbord- wie auf Steuerbordbug gleichermaßen einzusetzen.This invention is based on the object of an asymmetrical profile (greatest propulsion yield) both on courses on the wind without major complications To be used equally on port and starboard bow.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kippflügel drehbar (a-b) angebracht ist (Zeichnung I) und beim Wenden auf den entgegengesetzten Bug um (a-b) gekippt wird (1-2; 2-1). Dementsprechend wechselt auch das asymmetrische Profil (X) die Seite.The object is achieved according to the invention in that the tilt vane rotatable (a-b) is attached (drawing I) and when turning on the opposite Bow is tilted by (a-b) (1-2; 2-1). The asymmetrical one changes accordingly Profile (X) the side.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß ein asymmetrisches Profil mit optimalem Vortriebsbeiwert ohne komplizierte Mechanik zur Profiländerung beim Wenden auf den anderen Bug eingesetzt werden kann und daß der Kippflügel in verschiedenen Varianten (Zeichnung I bis V) sowohl für kleine Sport- wie für größere Frachtfahrzeuge eingesetzt werden kann.The advantages that can be achieved with the invention are, in particular, that an asymmetrical profile with an optimal propulsion coefficient without complicated mechanics can be used to change the profile when turning on the other bow and that the bottom-hung sash in different versions (drawing I to V) for both small ones Sports and can be used for larger cargo vehicles.

Verschiedene Ausführungsbeispiele sind in den Skizzen verdeutlicht. Es bedeuten: Zeichnung I = Kippprinzip des Flügels Zeichnung II = Teleskop- oder Klappprinzip Zeichnung III = Reihenanordnung der Kippflügel Zeichnung IV = V-Flügel mit verringerter Querkraft Zeichnung V = innen liegende Lagerung und die dadurch mögliche Überlappung der Kippflügel Weiter bedeuten a, b = Lagerpunkte des Kippflügels 1, 2 = Flügelspitzen X = Profilschnitt 3 = Teleskop- oder Klapp-Kippflügel LeerseiteVarious exemplary embodiments are illustrated in the sketches. It means: Drawing I = tilting principle of the wing Drawing II = telescopic or Folding principle Drawing III = row arrangement of the bottom-hung sashes Drawing IV = V-sashes with reduced transverse force Drawing V = internal bearing and the resulting possible overlap of the bottom-hung sashes a, b = bearing points of the bottom-hung sash 1, 2 = wing tips X = profile section 3 = telescopic or top-hung sash Blank page

Claims

Claims 1. Tilting vane as a wind drive of vehicles in particular of watercraft, characterized in that the wing mounted in the middle with an asymmetrical profile when turning is tilted over the horizontal and that Profile (despite the asymmetry) is properly flown against again (drawing I).

2. Tilting sash according to claim 1, characterized in that the for Deck facing wing side retracted or folded and the one facing upwards Is extended halfway to its full length (drawing II).

3. Tilting sash according to claim 1 and 2, characterized in that several Units are arranged one behind the other and / or next to one another (drawing III).

4. Tilting sash according to claim 1, 2, 3, characterized in that the Angle of incidence to the wind at the front bearing point (a) is set (mechanically, hydraulic, electric or a combination of these).

5. Tilting sash according to claim 1, 2, 3, characterized in that the The angle of attack to the wind at the rear bearing point (b) is set (mechanically, hydraulic, electric or a combination of these).

6. Tilting sash according to claim 1 to 5, characterized in that by the V-shaped arrangement of the bottom-hung sash provides the upper half for propulsion lower half but at the same time the unavoidable lateral force is reduced or stabilized (Drawing IV).

7. Tilting vane according to claim 1 to 6, characterized in that the large width when tilting the profile reduced by folding or telescopic tilting sashes will (drawing II).

8. Tilting vane according to claim 1 to 7, characterized in that the Bearing point (b) can also lie within the sash (drawing V) in such a way that that an overlap of the wings lying one behind the other is possible.
