Description

Kleinkalibriges Infanterie-Stahlmantelgeschoß mit ausschließlich innerer Treibladung. Die Erfindung betrifft ein kleinkalibriges Infanterie-Stahlmantelgeschoß mit ausschließiich innerer Treibladung. Die Wirkung des Geschosses wird dadurch verbessert, daß Innen- und Außenfläche des Mantels schwach konisch verlaufen, aber in entgegengesetzter I:ichtung zum inneren` Kegelstumpf, wobei dieser Mantel zwei Drittel der ganzen Geschoßlänge ausmacht. Wenn nämlich die ganze Seitenfläche am Lauf anliegt, so ist die Gaspressung beim Abfeuern auf die Seitenwand und auf den Lauf so groß, daß die Flugweite des Geschosses beeinträchtigt v.-ird. Die Anlagefläche des Geschosses am Lauf wird so auf ein Minimum zurückgeführt. Die eigentliche Führungsfläche befindet sich in der Höhe der Treibspiegelfläche, und nur der Wulst des -Mantelrandes liegt noch an der Lauffläche an. Infolge des Baues des Geschosses aber wirkt der Geschoßrand federnd und er schließt dicht ab, ohne aber einen besonderen Druck auszuüben, d. h. ohne erhebliche Bremswirkung. Eine solche Federung ist aber nur dadurch möglich, daß die Wand allmählich verläuft, weil in jedem anderen Falle ein Abreißen des Mantels stattfinden würde.Small caliber infantry steel jacketed bullet with exclusively internal Propellant charge. The invention relates to a small caliber infantry steel jacketed projectile with only internal propellant charge. The effect of the projectile is thereby improved that the inner and outer surfaces of the jacket are slightly conical, but in the opposite direction to the inner truncated cone, this jacket having two Makes up one third of the entire length of the storey. Namely, if the entire side surface is on Barrel is applied, the gas pressure when firing is on the side wall and on the Run so large that the flight range of the projectile is impaired. The contact surface of the bullet on the barrel is reduced to a minimum. The actual guide surface is at the level of the sabot surface, and only the bead of the mantle edge is still on the tread. As a result of the structure of the storey, however, the The edge of the bullet is springy and it closes tightly, but without exerting any particular pressure, d. H. without significant braking effect. Such a suspension is only possible if that the wall runs gradually, because in any other case the jacket will tear off would take place.

Das Geschoß besteht aus der Spitze a, die an der Stelle des größten Geschoßdurchmessers ihre Basis hat, die etwa in Höhe der Treibspiegelfläche b liegt. An der Außenwand befinden sich an dieser Stelle ganz dünnwandige, weiche Metallauflagen c, die so dünn sein können, daß sie auf galvanischem Wege aufgebracht werden. Diese Metallringe bestehen zweckmäßig aus einer Nickel-oder Kupferplattierung.The projectile consists of the point a, which is at the point of the largest Projectile diameter has its base, which is approximately at the level of the sabot surface b. At this point on the outer wall there are very thin-walled, soft metal layers c, which can be so thin that they are applied by electroplating. These Metal rings are expediently made of a nickel or copper plating.

Von dieser Basis A-B ab verläuft die Innenwandung d nach außen sich konisch er-«-eiternd. Die Außenfläche e aber läuft in entgegengesetzter Richtung konisch zu, aber nur ganz schwach konisch, und endet in bekannter Weise in den Wulst f, der noch etwas Tiber den Durchmesser A-B vorsteht, um dem feschoß den nötigen Drall zu verleihen. Das Geschoß lagert also lediglich an den Stellen c und f am Lauf an, und der durch den Innendruck hervorgerufene Widerstand ist auf das geringstmögliche Maß herabgesetzt. Infolge der Federung am freien Rande des Mantels ist auch der Druck in den Zügen ein beschränkter, und die Anlagefläche kann den gegebenen Verhältnissen in jedem Falle entsprechend nachgeben. Auf der ganzen Geschoßwand kommen also keine Reibungen der Außenfläche am Lauf, außer den beiden Anlagesteilen bei c und bei f, vor.From this base A-B, the inner wall d extends outwards conical he - «- festering. The outer surface e, however, runs in the opposite direction conically to, but only slightly conically, and ends in the known manner in the bead f, which protrudes a little over the diameter A-B to give the fezo the necessary To give twist. The projectile is only stored at points c and f am Start running, and the resistance created by the internal pressure is at the lowest possible level Dimension reduced. As a result of the suspension on the free edge of the coat is also the Pressure in the trains is limited, and the contact surface can meet the given conditions give in accordingly in each case. So there are none on the entire storey wall Frictions of the outer surface on the barrel, except for the two parts of the system at c and at f, before.
