Abstract (en)
[origin: US4716835A] A disintegrating projectile for cartridged maneuver ammunition for an automatic weapon. The projectile includes a thin-walled and closed body of plastic-like material. The body includes a circularly cylindrical section which changes into a tapering hollow tip. A rotationally symmetrical, stiffening, one-piece plastic insert, is adapted to the inner wall of the hollow tip and extends longitudinally of the projectile between a rear circular delimitation and a front circular limitation. The insert has the shape of two cups and includes a circular disc serving as a common bottom of the cups which are arranged one behind the other in the longitudinal direction of the projectile. The rear cup has a side wall thickness that constantly increases from the rear circular delimitation to the adjacent face of the circular disc member and the front cup has a side wall thickness that constantly increases from the front circular delimitation to the adjacent face of the circular disc member. The inner surface of the rear cup lies against the frontal face of a pressed body of metal powder. The projectile includes a hard elastic foam filling the area delimited by the inner surface of the front cup and the adjacent inner wall area at the frontal region of the projectile body.
Abstract (de)
Im Bereich der vorderseitigen Hohlspitze (20) einer aus Kunststoff gefertigte dünnwandige Hülle (10) ist an der Innenwandfläche (26) eine Rotationssymmetrische Einlage (30) aus Kunststoff angepaßt. Die Einlage (20) ist derart gestaltet, daß sie die Hülle (10) in einem Übergangsbereich (28) von der vorderen Begrenzung (33) aus zunehmend aussteift und damit sowohl einerseits eine ausreichende Widerstandsfähigkeit gegen einführbedingte schlagartige Beanspruchungen wie auch andererseits gewährleistet, daß hierdurch kein gefährliches, eine Sicherheitsgrenze vor einer Rohrwaffe überschreitendes Bruchstück gebildet wird.
