Description

Verfahren zur Herstellung von gepreßten Sätzen für Leuchtspur- und Raketengeschosse Die unter einem Druck von mehreren tauseind Atmosphären aus pulvrigem Material gepreßten Leuchtspursätze oder Treibsätze für Raketengeschosse werden beim Abschuß und beim Abbrennen einer außerordentlich hohen Beanspruchung unterworfen. Trotz der sorgfältigsten Herstellung beobachtet man häufig ein Herausschleudern, einzelner Teile des Satzes oder ein zu schnelles, sogar bis zur Detonation. führendes Abbrennen.Process for the production of pressed sets for tracer and Rocket projectiles Those under a pressure of several tauseind atmospheres of powdery Material pressed tracer sets or propellant charges for rocket projectiles are used at Fired and subjected to extremely high stress during burning. Despite the most careful production, one often observes a hurling out, individual parts of the sentence or too fast, even to the point of detonation. leading Burn down.

Es wurde nun gefunden, daß viele der genannten Versager darauf zurückzuführen sind, daß die gepreßten Sätze Einschlüsse von Luft enthalten, die mit dem Preßdruck, d. h. mit einigen tausend Atmosphären, verdichtet ist. Beim Nachlassen des Preßdruckes oder während des Abbrennens des Satzes dehnt sich die eingeschlossene Luft aus und sprengt Hohlräume in den Satz oder findet unter Bildung von Rissen und Kanälen einen Weg nach außen. Hierdurch wird einerseits das Gefüge der gepi@eßten Sätze gelockert und ihre Festigkeit und ihr Zusammenhalt verringert, andererseits bieten die entstandenen Risse und Öffnungen den glühenden Treibgasen Zutritt, die einzelne Teile des Satzes abreißen oder ein zu schnelles und unregelmäßiges Abbrennen bewirken.It has now been found that many of the failures mentioned can be attributed to this are that the pressed sets contain inclusions of air, which with the pressing pressure, d. H. with a few thousand atmospheres, is condensed. When the pressure is released or as the sentence burns, the trapped air expands and blows up voids in the sentence or finds one with the formation of cracks and channels Way to the outside. On the one hand, this loosens the structure of the pissed sentences and their strength and cohesion are reduced, on the other hand the resulting offer Cracks and openings allow the glowing propellant gases to enter the individual parts of the set tear off or cause too rapid and irregular burning.

Erfindungsgemäß werden diese Nachteile dadurch vermieden, daß das Pressen unter vermindertem Luftdruck oder im Vakuum vorgenommen wird, so daß Einschlüsse von Luft und die dadurch bedingten Hohlräume, Risse und Kanäle in den gepreßten Sätzen nicht entstehen.According to the invention, these disadvantages are avoided in that the Pressing is done under reduced air pressure or in a vacuum so that inclusions of air and the resulting cavities, cracks and channels in the pressed Sentences do not arise.
