  Vorrichtung zur Bestimmung der Fahrtrichtung von Luftfahrzeugen. 



   Die Erfindung bezieht sich auf eine Vorrichtung zur Bestimmung der Fahrtrichtung an Luftschiffen, bei welcher in bekannter Weise die Erdoberfläche durch Spiegel beobachtet wird und besteht darin,   dass   das   Visieriustrl1ment   ausserdem eine freie Durchsicht gestattet und dass im Visierinstrument   Strichmarken   angebracht sind. 



   Die Vorrichtung besteht in einer Doppelvisiereinrichtung, welche um eine vertikale Achse drehbar ist und welche es gestattet, durch ein   Fernrohr,   das durch Gewichts-   heschwerung   oder sonstwie in vertikaler oder annähernd vertikaler Lage gehalten wird, die scheinbare horizontale Verschiebung der auf der Erde befindlichen Gegenstände infolge der Ballon-Geschwindigkeit zu beobachten. Das in dem senkrecht nach unten gerichteten   Fernrohr   entstehende Bild wird durch ein Glasprisma oder einen Spiegel ins Okular des horizotalen Fernrohres geworfen, und zwar in der Weise, dass dieses Bild nur das halbe Gesichtsfeld des Fernrohres mit horizontaler Achse bedeckt.

   Im Gesichtsfeld des Prismas sind Linien in der Weise angebracht, dass sie in Vertikal-Ebenen, die parallel zur Achse des horizontalen Fernrohres verlaufen, sich befinden. Bei der Bewegung des Ballons werden nun die Gegenstände auf der Erde das Gesichtsfeld des Prismen-Fernrohres durchlaufen und man hat nur niitig, das horizontale   Fernrohr   solange zu drehen, bis die Bewegungrichtung der Gegenstände auf der Erde mit der Richtung der im Prismen-Fernrohr an-   gebrachten Linion zusammenfällt.   Dann befindet sich die Achse des horizontalen Fernrohres genau in der Richtung der Bewegung (rückwärts oder vorwärts) des Motor-Ballons. Man kann durch diese Einrichtung dauernd den Punkt am Horizont bestimmen, auf welchen

  Device for determining the direction of travel of aircraft.



   The invention relates to a device for determining the direction of travel on airships, in which the surface of the earth is observed in a known manner through mirrors and consists in the fact that the visor structure also allows a clear view and that line marks are attached in the sighting instrument.



   The device consists of a double sighting device which can be rotated around a vertical axis and which allows the apparent horizontal displacement of the objects on the earth as a result of a telescope which is held by weight or otherwise in a vertical or approximately vertical position watch the balloon speed. The image created in the telescope pointing vertically downwards is thrown through a glass prism or a mirror into the eyepiece of the horizontal telescope in such a way that this image only covers half the field of view of the telescope with the horizontal axis.

   In the field of view of the prism, lines are placed in such a way that they are located in vertical planes that run parallel to the axis of the horizontal telescope. When the balloon moves, the objects on the earth will pass through the field of view of the prism telescope and it is only necessary to turn the horizontal telescope until the direction of movement of the objects on the earth aligns with the direction in the prism telescope. brought Linion collapses. Then the axis of the horizontal telescope is exactly in the direction of movement (backwards or forwards) of the motor balloon. With this device one can constantly determine the point on the horizon, which one
