Definitions

  • the invention relates to a switch for an electric projectile detonator, which breaks through the water surface between firing and detonation, a spring-loaded pressure sensor being located on the front side of the projectile shell and opening and closing a contact (GB-A-578258).
  • Missile detonators have the task of releasing a warhead or an explosive charge at the target or at a desired time. As a rule, several switches are closed one after the other for ignition, which react to different environmental conditions.
  • Switches are known which react to the impact, to the passage of time, to the approach or to a certain distance from the target.
  • a projectile with a snap switch operated by back pressure is known from US-A-2 596 171.
  • a switch For projectiles that emerge from the water or that are immersed in the water, a switch is desired that registers the reaching of the water surface or falling below a minimum speed.
  • the invention has for its object to provide a switch for projectile detonator that changes its switching state when reaching the water surface or falling below a minimum speed.
  • a switch according to the invention for underwater projectiles or emerging projectiles is explained with reference to the single figure.
  • the figure shows the tip of the projectile 1, the pressure sensor 2, which is loaded with a spring 3, and the electrical contact 4.
  • the dynamic pressure 5 on the pressure sensor 2 causes a dynamic 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 becomes smaller than the spring force 7.
  • the contact 4 is closed and the ignition is thus triggered or initiated if another criterion for the ignition, e.g. B. Expiration of a time delay is used.
  • This switch is also used for a projectile that is immersed in the water from the air. However, the ignition is not released when the contact is closed, but when the contact 4 is opened.

  1. Contacteur pour un allumeur électrique d'un projectile qui traverse la surface de l'eau entre le tir et la détonation, un capteur de pression (2) chargé par un ressort (3) se trouvant sur le côté frontal de l'enveloppe du projectile (1) et ouvrant et/ou fermant un contact (4), caractérisé par le fait que le contacteur modifie son état de commutation par modification de la pression dynamique lors de variations de vitesse du projectile sous l'eau et lors du franchissement de la surface de l'eau.
