Definitions

  • the invention is concerned with the safety enhancement of modern ammunition, for example a 40mm impact ammunition, by incorporating a mechanical self-leveling device into the ammunition.
  • This is characterized by a simple structure and consists of a rotational spring, a lockable body and a cooperating with this body spring. The body is locked by a lock and a spring-supported mass.
  • the applicant offers such ammunition as low, medium and high-velocity cartridges, which stand out due to their high precision and reliability under all climatic conditions (http: //www.rheinmetall- defense.de/de/rheinmetall defense / svstems and products / weapons and ammunition / infant rvMOmm ammunition / index.php).
  • An important security requirement of such ammunition is to reduce the likelihood of a sharp detonator, etc., e.g. to prevent ignition if this is undesirable.
  • self-decomposition devices or mechanisms are additionally integrated into the ammunition. These are already known from various ammunition and can be performed electronically, pyrotechnic or mechanical.
  • a bomber with a Sebststzerlegung also discloses the DE 100 40 800 A1, a seibstneutraüsierenden Bombletzünder DE 44 21 353 C2.
  • the invention has the object to show a self-decomposition device with which the aforementioned disadvantages are avoided.
  • the invention is based on the idea to be able to implement or implement a mechanical self-decomposition device also later in the ammunition.
  • the set consists of, among other things, a setback body, a setback spring and a kind of locking / locking pin.
  • the rotation spring itself can also the triggering threshold, at which rotational speed of the igniter, the self-decomposition is activated, are set.
  • the locking pin locks the body until it falls below the adjustable speed of rotation of the igniter. This is tunable with the spring force of the rotary spring. With falling below the rotational speed of the body is then unlocked without loss of setback spring energy.
  • the setback body can also be used as a setback backup. It is also advantageous that retrofitting is possible in the case of detonators without a self-destructing device, but also in the case of detonators with pyrotechnic self-decomposition.

By the movement of the body 3 upwards this can drive the rotor A with detonator at the head detonator or a tapping needle (not shown in detail) at the bottom igniter up, ignite this.

Abstract

L'invention concerne un dispositif d'autodestruction mécanique (10) au sein d'une munition (11). Ledit dispositif est constitué d'un ressort rotationnel (2) d'un corps verrouillable (3) ainsi que d'un ressort (4) coopérant avec le corps (3). Le verrouillage du corps (3) est réalisé au moyen d'un organe de verrouillage (7) et d'une masse (6) montée sur un ressort. Lorsque la cartouche / munition (11) subit une accélération, le corps (3) est accéléré vers le bas et le ressort (2) est tendu. Sous l'effet de la rotation de la cartouche (11), l'organe de verrouillage (7) s'enfonce dans la masse (6) montée sur sur ressort, pour ainsi verrouiller le corps (19. Pendant la séquence d'armement de la cartouche (11), on fait pivoter un rotor (A) depuis une position de sécurité dans une position d'armement. Si la vitesse de rotation passe en-dessous d'une valeur (pré)définie, l'organe de verrouillage (7) retourne dans sa position d'origine. Cela implique également un déverrouillage du corps (3) verrouillé lequel est accéléré vers le haut sous l'effet du ressort rotationnel (2). Suite au déplacement du corps (3) vers le haut, celui-ci peut pousser vers le haut soit le rotor (A) doté d'un détonateur, dans le cas d'une fusée de tête, soit une aiguille de perçage, dans le cas d'une fusée de culot, pour ainsi déclencher le détonateur / la fusée.
