Description

Flugzeug. Die Erfindung bezieht sich auf Flugzeuge mit und ohne Motor, deren Tragflächen um eine quer zur Flugrichtung liegende Achse schwingbar angeordnet sind.Plane. The invention relates to aircraft with and without engine, whose wings are arranged to be able to swing about an axis lying transversely to the direction of flight are.

Eine durch den Rumpf oder ein Flächenmittelstück geteilte Tragfläche a ist um eine Querachse c drehbar und mittels Gestänge b (Abb. 2) mit einer Feder d verbunden. Liegt die Drehachse vor dem Druckmittelpunkt des Flügels, wie in Abb. z dargestellt ist, so versucht der im Fluge auftretende Luftdruck, die Tragfläche nach hinten aufzukippen, was die Zugfeder d verhindert. Durch den Handhebel e kann die Tragfläche verstellt werden.A wing divided by the fuselage or a center section of the wing a can be rotated around a transverse axis c and with a spring by means of linkage b (Fig. 2) d connected. If the axis of rotation is in front of the center of pressure of the sash, as shown in Fig. z is shown, the air pressure occurring in flight tries the wing to tip backwards, which prevents the tension spring d. The hand lever e can the wing can be adjusted.

Diese Feder d, welche also dem im Fluge auftretenden Luftdruck entgegenwirkt, bedingt ein völlig automatisches Anpassen der Tragfläche in bezug auf turbulente Luftströmungen, wodurch auch in Böen ein völlig ruhiger Flug gegeben ist und das Flugzeug die Böen zum Teil sogar als Auftriebskräfte gebrauchen kann. Durch diese Anordnung wird bei Motorflugzeugen ein sehr ökonomischer Flug erzielt, während motorlose Segelflugzeuge sogar einen aerodynamischen Segeleffekt erzielen können. Ferner dient die Feder d bei flügelgesteuerten Flugzeugen noch zur Entlastung des oder der Steuerhebel. Liegt der Drehpunkt a hinter dem Druckmittelpunkt, so mu$ die Feder d eine Druckfeder sein.This spring d, which thus counteracts the air pressure occurring in flight, requires a completely automatic adjustment of the wing with respect to turbulent Air currents, whereby a completely calm flight is given even in gusts and that Airplane can even use the gusts as lift forces. Through this Arrangement, a very economical flight is achieved in motorized aircraft, while motorless Gliders can even achieve an aerodynamic gliding effect. Also serves the spring d in wing-controlled aircraft to relieve the control lever or levers. If the fulcrum a lies behind the center of pressure, the spring d must be a compression spring be.

Claims (1)

PATENT-ANsPRuCIi: Flugzeug mit in wagerechten Querachsen gelagerten, von Federn beeinflußten Tragflächen, dadurch gekennzeichnet, daß die Tragflächen, deren jede durch einen Steuerhebel beliebig verstellt werden kann, nur nach der dem Luftdruck entgegenwirkenden Seite unter Federspannung gehalten werden. PATENT APPLICATION: Airplane with wings influenced by springs and mounted in horizontal transverse axes, characterized in that the wings, each of which can be adjusted as required by a control lever, are kept under spring tension only on the side counteracting the air pressure.
