Description
Es ist bekannt, Geschwindigkeiten von Geschossen durch Beobachtung der Veränderung zweier von diesen durcheilter Felder zu bestimmen. It is known to determine the speeds of projectiles by observation to determine the change in two of these fields passed through.
Zu diesem Zweck wurden magnetische Wechselfelder benutzt, und diese hatten den Nachteil, daß sie nur zur Geschwindigkeitsbestimmung magnetisierbarer Körper verwendbar waren. Außerdem waren zur Erzeugung derartiger Wechselfelder Spulen erforderlich, und diese waren ihrem Charakter entsprechend räumlichen Abmessungen unterworfen und an die Größe der Geschosse sowie an die Streuung der Geschoßbahnen gebunden.For this purpose, alternating magnetic fields were used, and these had the disadvantage that they can only be magnetized to determine the speed Body were usable. In addition, coils were used to generate such alternating fields required, and these were spatial dimensions in accordance with their character subject and the size of the projectiles and the spread of the projectile trajectories bound.
Darüber hinaus unterlagen die Spulen gerade wegen ihrer räumlichen Ausdehnung in hohem Maße der Gefahr einer Beschädigung oder Zerstörung durch die Geschosse, was ein erhebliches Kostenrisiko bedeutete und somit zu Schutzmaßnahmen und zur Anordnung teurer Panzerplatten zwang. Unter diesen Voraussetzungen kamen die bekannten Meßgeräte der in Rede stehenden Art zur Geschwindigkeitsbestimmung großer Geschosse überhaupt nicht in Betracht.In addition, the coils were subject to precisely because of their spatial dimensions Extending to a great extent the risk of damage or destruction by the Projectiles, which meant a significant cost risk and thus to protective measures and forced the arrangement of expensive armor plates. Under these conditions came the known measuring devices of the type in question for determining speed large projectiles out of the question.
Der Erfinder hat diese Nachteile erkannt und bewußt einen Weg gesucht, der sie zu umgehen vermochte. Gemäß seinem Vorschlag ist dies durch eine Vorrichtung zum Messen der Geschwindigkeiten von bewegten Körpern mit mehreren zur Beobachtung von Zeitdifferenzen hintereinander von den Körpern zu durchquerenden und dadurch zu verändernden Feldern möglich geworden, bei der gemäß der Erfindung unter Verwendung elektrischer Felder für deren Aufbau eindimensionale, frei im Raum angeordnete Elektroden dienen. The inventor recognized these disadvantages and consciously sought a way who was able to bypass them. According to his proposal, this is by means of a device for measuring the speeds of moving bodies with several for observation of time differences one after the other to be traversed by the bodies and thereby fields to be changed become possible when using according to the invention electric fields for their construction one-dimensional, freely arranged electrodes to serve.
Dabei kann es zweckmäßig sein, daß am Meßort zwei eine Verkürzung des Spannungsdiagramms bewirkende eindimensionale Elektroden einander zugeordnet sind. It can be useful that two shortenings at the measuring point of the voltage diagram causing one-dimensional electrodes are assigned to one another are.
Ferner ist es für bestimmte Fälle vorteilhaft, wenn die Apparatur einschließlich etwaiger Zuleitungen gegen eine Beeinflussung durch Schallwellen geschützt ist. It is also advantageous in certain cases if the apparatus including any supply lines against the influence of sound waves is protected.
An Hand der Zeichnung ist die Erfindung beispielsweise erläutert. The invention is explained by way of example with the aid of the drawing.
Fig. I zeigt eine Elektrode a, die um sich ein durch die Linien b angedeutetes gleichmäßiges Feld aufbaut. Wird dieses von einem Geschoß c durchquert, so verändert sich das Feld derart, daß mit einem Feldstärkemeßgerät ein Spannungsdiagramm gemäß Fig. 2 beobachtet wird. Auf der Ordinate werden die Spannungen u und auf dessen Abszisse die Zeiten t aufgetragen. Es ist ersichtlich, daß die Kurve x ziemlich flach verläuft. Fig. I shows an electrode a, which is surrounded by the lines b indicated even field builds up. If this is crossed by a floor c, so the field changes in such a way that with a field strength meter a voltage diagram according to FIG. 2 is observed. The voltages u and its on the ordinate The times t are plotted on the abscissa. It can be seen that the curve x is quite runs flat.
Wird der Elektrode a eine zweite Elektrode h zugeordnet, so erfolgt zwischen diesen beiden eine Konzentration des Feldes gemäß Fig. 3 und dadurch eine Verkürzung des Spannungsdiagramms, wie es durch die Kurve y angedeutet ist. Dadurch sind genauere Messungen möglich. If a second electrode h is assigned to the electrode a, this takes place between these two a concentration of the field according to FIG. 3 and thereby a Shortening of the voltage diagram, as indicated by curve y. Through this more precise measurements are possible.
Versuche haben ergeben, daß die Meßwerte unter Umständen durch Schallwellen, die beim Abschluß entstehen, gestört werden können. Dies trifft insbesondere dann zu, wenn die Geschosse eine geringere Geschwindigkeit haben als der Schall. Diese Schwierigkeiten, deren Ursachen nicht ohne weiteres erkennbar waren, können somit dadurch vermieden werden, daß man die Apparatur einschließlich etwaiger Zuleitungen gegen eine Beeinflussung durch Schallwellen schützt. Tests have shown that the measured values may be caused by sound waves, which arise at the end can be disturbed. This is especially true then when the projectiles have a slower speed than the sound. These Difficulties, the causes of which were not immediately recognizable, can thus be avoided by having the apparatus including any supply lines protects against the influence of sound waves.
Fig. 4 zeigt eine ganze Apparatur. Diese enthält einen Hochfrequenzgenerator und eine Verstärkereinrichtung in einem Hauptgerät d. An dieses sind in bekanntem Abstand zwei Geber e, f angeschlossen, von denen jeder eine Elektrodenkombination g, li trägt. Das Hauptgerät d speist eine Auswerteeinrichtung i, z. B. in Form eines elektronischen Zählgerätes oder eines Oszillographen. Fig. 4 shows a whole apparatus. This contains a high frequency generator and a repeater in a main body d. At this are in known Distance two sensors e, f connected, each of which is an electrode combination g, li wears. The main unit d feeds an evaluation device i, e.g. B. in the form of a electronic counter or an oscilloscope.
Durch die zwischen den Elektrodenkombinationen g, h aufgebauten Wechseifelder K fliegt das Geschoß m. Die Verformungen der Felder werden in der Einrichtung i registriert und ausgewertet. Because of the alternating fields built up between the electrode combinations g, h K flies the projectile m. The deformations of the fields are in the device i registered and evaluated.
Die Erfindung ermöglicht eine Geschwindigkeitsmessung auch an nicht metallischen und sehr kleinen Körpern. The invention also does not allow a speed measurement metallic and very small bodies.
