Description

Die Erfindung hat eine Vorrichtung zum Gegenstande, die das selbsttätige Abwerfen von Bomben bewirkt, nachdem der Führer ein mit einem Kontakthebel versehenes Zielfernrohr auf das Ziel eingestellt hat, auf welches die Bomben abgeworfen werden sollen, und einen Motor in Gang gesetzt hat, der nicht nur die selbsttätige Weiter drehung des eingestellten Zielfernrohres bewirkt, sondernThe invention has a device for the subject, the automatic dropping effected by bombs after the guide a telescopic sight provided with a contact lever has adjusted to the target on which the bombs are to be dropped, and has set a motor in motion that not only keeps the adjusted riflescope causes, but

ίο auch die Bomben abwirft, sobald der elektrische Kontakt zweier Stromkreise geschlossen wird.ίο also drops the bombs as soon as the electric Contact between two circuits is closed.

In den einen Stromkreis ist ein elektrischer Motor, die Drehvorrichtung für das Zielf ernrohr und eine Einstellvorrichtung und in den anderen Stromkreis die Bombenabwurfvorrichtung eingeschaltet. Die Einstellvorrichtung ist derart eingerichtet, daß sie die Geschwindigkeit des Motors nach der jeweiligen Flugzeuggeschwindigkeit und -höhe regelt, damit der Motor das Fernrohr in eine entsprechende Winkeldrehung versetzt.In one circuit there is an electric motor, the rotating device for the telescopic sight and a setting device and in the other circuit the bomb dropping device switched on. The adjustment device is set up in such a way that it adjusts the speed of the motor according to the respective aircraft speed and altitude, so that the motor controls the telescope in an appropriate manner Angular rotation offset.

• An dem sich horizontal in Richtung' des Pfeiles fortbewegenden Flugzeuge ι sind eine Reihe von Sprengkörpern 2, nicht wie gezeichnet hintereinander, sondern zweckmäßig nebeneinander · derart angehängt, daß ihre Freigabe durch Stromschluß einer elektrisehen -Batterie in an sich bekannter Weise erfolgt. Die horizontale Flugzeugachse befindet sich vom Erdboden in einem jederzeit feststellbaren Abstande 3, 4. Der Punkt 3 bildet gleichzeitig die Achse einer in einer kardanischen Aufhängung/ horizontal gelagerten Welle, während mit 4 der jeweilige Fußpunkt der Flughöhe bezeichnet ist. Senkrecht zur Welle 3 ist ein um diese Welle in vertikaler Ebene schwingbares Fernrohr 5 angeordnet, das auf den Zielpunkt 6 gerichtet wird, auf den ein Sprengkörper 2 nach Zurücklegung· der gebogenen Bahn 3, 6 (Fig. 1. und 2) niederfallen soll.• On the aircraft moving horizontally in the direction of the arrow there are Row of explosive devices 2, not one behind the other as drawn, but expedient next to each other · attached in such a way that they can be released when an electric current is connected -Battery takes place in a known manner. The aircraft's horizontal axis is located from the ground at a distance that can be determined at any time 3, 4. The point 3 at the same time forms the axis of a gimbal mounted / horizontally mounted Wave, while 4 denotes the respective base point of the flight altitude. Perpendicular to the shaft 3 is a telescope 5 that can swing around this shaft in a vertical plane arranged, which is aimed at the target point 6, at which an explosive device 2 after covering · the curved path 3, 6 (Fig. 1. and 2) should fall.

In dem Dreieck 3, 4, 6 (Fig. 3) läßt sich der Winkel 4, 3, 6 — α bei jeder Geschwindigkeit und Höhe des Fahrzeuges rechnerisch oder graphisch bestimmen. Hieraus folgt, daß das Auslösen eines Sprengkörpers von seinem Aufhängepunkt dann erfolgen muß, sobald das auf weite Entfernungen (Fig. 4) auf das Ziel gerichtete Fernrohr 5, dem man eineIn the triangle 3, 4, 6 (Fig. 3) the angle 4, 3, 6 - α can be at any speed and determine the height of the vehicle arithmetically or graphically. It follows that the triggering of an explosive device of its suspension point must then be carried out as soon as that on long distances (Fig. 4) the aiming telescope 5, to which one

gives the rotation movement adapted to the aircraft speed, with which the perpendicular 3, 4 forms the A-angle α calculated from the respective aircraft speed and altitude.

For the practical implementation of the method, a series of values for the Aangle α are determined and plotted on a vertical graduation disk 7. Above the disk 7, a pointer, lever 8, which is arranged so that it can swing on the shaft 3, can be moved and adjusted to an angle corresponding to the respective flight speed and altitude. The pointer lever 8 is equipped with a contact pin 9, which is shown in

! 5 oscillates in the same circle as the contact pin 10 of a lever arm 11 arranged perpendicular to the telescope axis. The contact pins 9 and 10 are drawn in FIGS. 3 and 4 in the same plane for the sake of clarity, in which the lever arms 8 and τ ι move. In reality, the contact pins are standing 9 and 10 perpendicular to the plane of the drawing and delete when moving towards each other the lever arms past each other.

If the telescope 5 of the horizontally moving aircraft is now aimed at the target 6 directed (Fig. 4), the pointer lever 8 on the known speed and known Flying height determined, set on the disc 7 applied angle and then the Axis 3 of the telescope 5 in a rotational movement corresponding to the aircraft speed offset, then the telescope lever arm 11 approaches according to Fig '. 4 for a left turn the axis 3 the pointer lever 8, until finally the contact points 10 and 9 at their comparison close the electric current of a battery τ2.

Devices for the automatic dropping of explosive devices from aircraft, in which the telescopic sight provided with a contact and a second according to speed and Flying height adjustable contact is available to an electrical through the power supply Trigger bomb dropping device are known.

A lever 13, the free end 14 of which is connected to the circuit of the battery 12 can be brought into conductive connection with contacts 15. The contacts 15 are conductively connected to electromagnets 16, which are present in such a number as an explosive body should come to use. The electromagnets 16 operate in on.

'known' way the triggering devices of the explosive bodies.

In order to make the safe operation of the device perceptible for the observer, an alarm bell 17 and a galvanometer 18 are switched into the circuit.

The alarm bell 17 is activated by a contact 19 on the pointer lever 8 and a spring contact 20 on the lever arm 11. before tripping the bomb-dropping device, e.g. B. set to 20 seconds and gives the observer known that the dropping of the explosive body is to be expected.

On the horizontal axis of movement 3 of the telescope 5 sits a gear wheel 2i, which with the gear 22 is in engagement. The gear 22 is fastened on an axle 23. on the axis 23 a second gear 24 is attached to a gear 25 of the shaft 26 is engaged. The AVelle 26 is driven by an electric motor 27, which is switched on by a lever 28, the is mounted swingable over a graduation 29. The graduation 29 gives the Position to which the lever arm 28 at the respective speed of the aircraft is to be set.

The operation of the device is as follows:

During horizontal flight, if the observer has the Aangle c /. on "the graduation disc 7 by means of the pointer lever 8, then he sights the target 6 with the telescope 5 (FIG. 4) and sets the lever arm 28 on the graduation which corresponds to the respective aircraft speed. The motor 27 is thereby switched on and 4, until the contact 10 of the lever arm 11 is opposite the contact 9 of the pointer lever 8 and a current occurs in that circuit which, by setting the contact lever 13, 14 on the contact 15 for the associated electromagnet 16 The electromagnet 30, which is also switched on in this circuit, is simultaneously excited and the armature 31 is attracted The telescope is sti presented. The circuit remains closed while the contacts 9 and 10 are juxtaposed, so that further explosive bodies can be thrown off quickly one after the other by further turning the lever 13.
