Die Erfindung betrifft einen Zünder für Unterwasserprojektile.The invention relates to a fuse for underwater projectiles.
Zünder haben die Aufgabe, einen Gefechtskopf oder eine Sprengladung im Ziel oder zu einem gewünschten Zeitpunkt zu zünden, d. h. zur Wirkung zu bringen.The task of detonators is to create a warhead or an explosive charge to ignite at the target or at a desired time, d. H. to bring to effect.
Bekannt sind Aufschlagzünder, Zeitzünder, Annäherungszünder und Abstandszünder.Impact fuses, time fuses, proximity fuses and distance fuses are known.
Für Unterwasserprojektile, eintauchende oder auftauchende Projektile, ist ein Zünder erwünscht, der das Erreichen der Wasseroberfläche oder das Unterschreiten einer Mindestgeschwindigkeit registriert. For underwater projectiles, immersing or emerging Projectiles, a detonator is desired that registers the reaching of the water surface or the falling below a minimum speed.
Der Erfindung liegt die Aufgabe zugrunde, beim Erreichen der Grenzfläche Wasser/Luft oder bei Unterschreiten einer Mindestgeschwindigkeit ein Projektil zu zünden.The invention is based on the object in achieving the The water / air interface or to ignite a projectile when the speed falls below a minimum.
Die Aufgabe wird erfindungsgemäss gelöst durch einen Zünder, bei dem sich an'der Stirnseite einer ProjektilhülLe ein mit einer Feder belasteter Druckaufnehmer befindet, welcher bei einer Vorwärtsbewegung des Projektils unter Wasser durch den Staudruck einen Schalter geöffnet hält und bei Durchstossen der Wasseroberfläche oder bei zu geringer Geschwindigkeit den Schalter durch Federkraft schliesst und damit eine Zündung auslöst. ·The object is achieved according to the invention by an igniter, in which there is a projectile casing on the end face a spring-loaded pressure transducer is located, which when the projectile moves forward underwater through the Dynamic pressure keeps a switch open and when the water surface is pierced or when the speed is too low closes the switch by spring force and thus triggers an ignition. ·

- Insensitivity to disturbances.
Ausbildungen der Erfindung sind Gegenstände von Unteransprüchen. Developments of the invention are the subject matter of subclaims.
Ein erfindungsgemässer Zünder für Unterwasserprojektile oder auftauchende Projektile wird anhand der einzigen Figur erläutert. A fuse according to the invention for underwater projectiles or emerging projectiles is explained with reference to the single figure.
Die Figur zeigt die Spitze des Projektils 1, den Druckaufnehmer 2, der mit einer Feder 3 belastet ist und den elektrischen Schalter 4.The figure shows the tip of the projectile 1, the pressure transducer 2, which is loaded with a spring 3 and the electrical switch 4.
Sicherungssysteme, die zur Erreichung der Rohrsicherheit und der Vorrohrsicherheit notwendig sind, sind nicht Gegenstände dieser Erfindung und nicht in die Zeichnung mitaufgenommen.Safety systems that are necessary to achieve pipe safety and upstream pipe safety are not objects of this invention and not included in the drawing.
Wird das Projektil unter Wasser abgeschossen und bewegt es sich mit ausreichender Geschwindigkeit', so bewirkt der Staudruck 5 auf dem Druckaufnehmer 2 eine Staukraft 6, die die Federkraft 7 übersteigt. Der Schalter bleibt offen. Sinkt die Geschwindigkeit unter einen Grenzwert oder taucht das Projektil aus dem Wasser auf, so wird die Staukraft 6 kleiner als die Federkraft 7. Der Schalter 4 wird geschlossen und damit die Zündung ausgelöst oder eingeleitet, falls zur Zündung noch ein weiteres Kriterium z.B. Ablauf einer Zeitverzögerung verwendet wird.If the projectile is fired under water and it moves with sufficient speed ', so causes the back pressure 5 on the pressure transducer 2, a backing force 6 which exceeds the spring force. 7 The switch remains open. If the speed drops below a limit value or if the projectile emerges from the water, the damming force 6 is smaller than the spring force 7. The switch 4 is closed and thus the ignition is triggered or initiated, if another criterion for the ignition, e.g. expiry of a time delay is used.
Dieser Zünder findet auch bei einem Projektil Verwendung, welches von der Luft ins Wasser taucht. Allerdings erfolgt die Freigabe der Zündung dann nicht beim Schliessen, sondern beim öffnen des Schalters 4.This detonator is also used with a projectile, which dips from the air into the water. However, the ignition is not released when it is closed, but when opening the switch 4.
