Description
Die Erfindung bezieht sich auf ein Flugzeug mit durch Spalträume unterteiltem Flügel, bei dem die Spalträume in Abhängigkeit von einer waagerechten Steuerfläche selbsttätig oder WiIlkürlich verschließbar sind. Bei den bekannten Flugzeugen dieser Art werden die auf der Flügeloberseite befindlichen Spaltöffnungen geschlossen,, während diejenigen auf der Flügelunterseite offen bleiben. Dadurch bilden sichThe invention relates to an aircraft with a wing divided by gap spaces which the gap spaces automatically or arbitrarily depending on a horizontal control surface are lockable. In the known aircraft of this type, the Upper side of the wing closed stomata, while those on the underside of the wing remain open. This creates
ίο aber an den letztgenannten unteren Spaltöffnungen Wirbel, welche infolge Erhöhung des Widerstandes die Wirkung des Tragflügels erheblich herabsetzen. Demgegenüber besteht zur Abstellung dieses Nachteiles die Erfindung darin, daß der aus Jalousieflächen bestehende Verschluß die auf der Flügelunterseite befindlichen Spaltöffnungen abdeckt.ίο but at the last-mentioned lower stomata Vortices, which, as a result of an increase in drag, considerably reduce the effect of the wing reduce. In contrast, there is the invention to remedy this disadvantage in that the shutter consisting of shutter surfaces is located on the underside of the wing Covers stomata.
Eine Ausführungsform des Erfindungsgegenstandes ist in der Zeichnung schematisch dargestellt, und zwar zeigt Fig. ι das Flugzeug bei nach unten gedrehter und Fig. 2 bei in der Normallage sich befindender Klappe.An embodiment of the subject matter of the invention is shown schematically in the drawing, namely Fig. ι shows the aircraft when rotated downwards and FIG. 2 when in the Normal position of the flap.
Der Tragflügel besteht aus den durch, die Spalträume« und b voneinander getrennten Tragflügelteilen c, d, e, von welchen der hinterste Tragflügelteil e, das sogenannte Querruder, um die Achse f aus der Stellung der Fig. 2 in diejenige der Fig. 1 und umgekehrt gedreht werden kann. The wing consists of the wing parts c, d, e separated from one another by "the gaps" and b , of which the rearmost wing part e, the so-called aileron, moves around the axis f from the position of FIG. 2 to that of FIGS can be rotated the other way around.
Gemäß der Erfindung sind in den Einmündungen der Spalträume α und b an der Unterseite des Flugzeugtragflügels Jalousieflächen g angeordnet, welche bei der Verstellung des Querruders in die Lage der Fig. 2 mit verstellt werden. Zu diesem Zwecke bildet jede Jalousiefläche g den einen Arm eines doppelarmigen Hebels g, i und sind sämtliche Hebelarme i durch Stangen h und k' miteinander verbunden, während andererseits die letztgenannten Stangen durch die Stangen I und V an den Stellhebel m des Querruders e derart angeschlossen sind, daß bei in der Lage der Fig. 2 sich befindendem Querruder die Jalousieöfmungen geschlossen und bei in der Lage der Fig. 1 sich.; befindendem Querruder geöffnet sind. According to the invention, blind surfaces g are arranged in the junctions of the gap spaces α and b on the underside of the aircraft wing, which blind surfaces g are also adjusted when the aileron is adjusted to the position of FIG. For this purpose, each blind surface g forms one arm of a double-armed lever g, i and all lever arms i are connected to one another by rods h and k ' , while on the other hand the latter rods are connected to the control lever m of the aileron e by rods I and V in this way are that when the aileron is in the position of FIG. 2, the blind openings are closed and when in the position of FIG. 1 they are closed. ; ailerons are open.
Grundsätzlich würde es ausreichen, von dem die Jalousieflächen verstellenden Gestänge k, I und k', V abzusehen, da schon der an der Unterseite des Tragflügels sich bildende Über- oder Unterdruck das selbsttätige öffnen oder Schließen der Jalousieflächen g bewirkt. Trotzdem ist es aber, um sich nicht einem zufälligen Versagen der Einrichtung auszusetzen, zweckmäßig, das Gestänge anzubringen.In principle, it would be sufficient to disregard the linkage k, I and k ', V that adjusts the blind surfaces, since the overpressure or negative pressure that forms on the underside of the wing causes the blind surfaces g to open or close automatically. Nevertheless, in order not to expose yourself to accidental failure of the device, it is expedient to attach the linkage.
Wesentlich ist, daß die Einmündungen der im vorderen Teile des Tragflügels angeordneten Spalträume mit solchen Jalousieflächen versehen sind, da nach den vorliegenden Erfahrungen das Offensein der Einmündungen der hinteren Spalträume sich nicht als übermäßig nachteilig herausgestellt hat.It is essential that the junctions of the arranged in the front part of the wing Gaps are provided with such blind surfaces, as based on the experience available the openness of the confluences of the posterior crevices does not prove to be unduly disadvantageous has turned out.
