Abstract

The invention with the title "toy flying body (propeller kite) with propellers rotating in opposite directions" relates to a novel structural principle for kites. The bearing surfaces of the kite substantially consist of at least two axially rotating propellers (1, 2), wherein an oblique position of bearing surfaces or parts of bearing surfaces in the wind is obtained as a result of the flexibility of the rods fixed to the axis of rotation or as a result of the distortion of wing surfaces. According to the invention, a particularly stable flying performance is achieved, with a correspondingly designed kite, in that propellers with opposite directions of rotation are used. <IMAGE>

Description

Die Erfindung betrifft ein neuartiges Konstruktionsprinzip für Drachen.The invention relates to a novel design principle for kites.

Als Drachen werden Flugkörper mit Tragflächen bezeichnet, die an einer oder mehreren Schnüren schräg gegen den Wind gestellt im Luftstrom Auftrieb erhalten und fliegen. Drachen finden vorzugsweise als Spielzeug Verwendung. Drachen werden auch für technische Zwecke z.B. als Träger für Antennen eingesetzt.Missiles with wings are referred to as kites, which are lifted and flown in the air flow on one or more cords at an angle to the wind. Dragons are mainly used as toys. Kites are also used for technical purposes e.g. used as a carrier for antennas.

In der Vergangenheit wurden verschiedene Versuche unternommen, hubschrauberartige Drachen mit permanent schräggestellten Tragflächen oder permanent schräggestellten Tragflächenteilen zu konstruieren, bei denen windmühlenartige Drehbewegungen von einer oder mehreren Tragflächen ausgeführt werden. Entsprechende Konstruktionen sind in der Patentliteratur unter DE-GM 75 13 285 und US 24 72 290 dokumentiert. Alle diese Drachen weisen aufgrund der permanenten Schrägstellung der Rotoren bei wechselndem Wind ein sehr Ungünstiges Flugverhalten auf. Die permanente Schrägstellung der Rotoren führt bei kurzzeitig geringer Windgeschwindigkeit zu einem starken Abbremsen und Stillstand der Drehbewegung. Dadurch wird der Auftrieb stark vermindert.Various attempts have been made in the past to construct helicopter-like kites with permanently inclined wings or permanently inclined wing parts in which windmill-like rotary movements are carried out by one or more wings. Corresponding constructions are documented in the patent literature under DE-GM 75 13 285 and US 24 72 290. Due to the permanent inclination of the rotors in changing winds, all of these kites have a very unfavorable flight behavior. The permanent inclination of the rotors leads to a short drop Wind speed to a strong braking and the rotation stops. This greatly reduces buoyancy.

In der Offenlegungsschrift DE 31 40 251 werden Spielzeug-Flugkörper beschrieben, bei denen vorzugsweise flache drehbare Tragflächen verwendet werden, die aufgrund der unterschiedlichen Biegsamkeit von Stützstäben eine Schrägstellung der Tragflächen im Wind erfahren.
Entsprechen aufgebaute Drachen mit zwei oder mehreren flachen Windrädern weisen ein instabiles Flugverhalten auf. Bedingt durch die Rotation drehen sich die an einer Halteschnur fliegenden Drachen aus dem Wind.In the published patent application DE 31 40 251, toy missiles are described in which preferably flat, rotatable wings are used, which due to the different flexibility of the support rods experience an inclined position of the wings in the wind.
Correspondingly constructed kites with two or more flat wind turbines have an unstable flight behavior. Due to the rotation, the kites flying on a tether turn out of the wind.

Dieser Mangel wird durch die vorliegende Erfindung behoben. Die windradartigen Tragflächen des Drachens werden mit entgegengesetzten Drehrichtungen nebeneinander oder hintereinander angeordnet. Dadurch gleicht sich der Einfluß des Drehens auf den Flug aus.
Die Anwendung des erfindungsgemäßen Drachens ist vorzugsweise als Spielzeug oder Sportgerät vorgesehen.This defect is remedied by the present invention. The wind turbine-like wings of the kite are arranged side by side or one behind the other with opposite directions of rotation. This balances the influence of turning on the flight.
The use of the kite according to the invention is preferably provided as a toy or sports device.

Beispiel 1:Example 1:

In Abb. 1 ist ein nichtbeschränkendes Beispiel für die Konstruktion eines Drachens mit flachen Windrädern wiedergegeben, bei denen die sich in entgegengesetzter Richtung drehenden Tragflächen 1 und 2 des Drachens nebeneinander an einem Haltegestell 3 mit Rotationsachsen befinden.In Fig. 1 is a non-limiting example of the construction of a kite with flat wind turbines, in which the wings 1 and 2 of the kite rotating in the opposite direction are next to each other on a support frame 3 with axes of rotation.

Beispiel 2:Example 2:

In Abb. 2 ist ein nichtbeschränkendes Beispiel für einen Drachen wiedergegeben, bei dem sich die gegenläufigen Windräder 1 und 2 hintereinander auf einer Rotationsachse 3 befinden. Der Drachen wird durch eine oder mehrere Halteleinen 4 im Wind gehalten.Fig. 2 shows a non-limiting example of a kite, in which the opposing wind turbines 1 and 2 are located one behind the other on an axis of rotation 3. The kite is held in the wind by one or more retaining lines 4.
