Abstract

Die Erfindung betrifft einen segmentierten Treibkäfig für ein unterkalibriges langgestrecktes Wuchtgeschoß. Als Maß­ nahme zur Erhöhung der Biegesteifigkeit eines Treibkäfig-­ Segmentes sind zwischen vorderem Führungsflansch und hinte­ rem Druckflansch verlaufende Längsrippen bekannt. The invention relates to a segmented sabot for a sub-caliber elongated balancing projectile. As a measure to increase the bending stiffness of a sabot Segments are between the front guide flange and the rear Rem known pressure flange extending longitudinal ribs.

Derartige Längsrippen tragen aber im wesentlichen nicht zur Übertragung von Schubkräften vom Treibkäfig in den Um­ fang des Geschoßkörpers während der Beschleunigungsphase im Rohr bei und sind herstellungsmäßig nur in zahlreichen aufeinander folgenden kostenintensiven Fertigungsschritten herzustellen. However, such longitudinal ribs do not essentially carry to transfer thrust from the sabot to the um catch the projectile body during the acceleration phase in the tube and are only in numerous production terms successive cost-intensive manufacturing steps to manufacture.

Mit dem erfindungsgemäßen Treibkäfig (60) soll bei weite­ rer Verminderung des Totlastanteiles die Biegesteifigkeit unter Berücksichtigung möglicher kostengünstiger Serienfer­ tigung erhöht werden. Dies gelingt mit der Erfindung da­ durch, daß der Gesamtquerschnitt (50) des Treibkäfigs (60) wenigstens in Teilbereichen (36, 24) seiner Längenerstrek­ kung eine im wesentlichen polygonförmige Querschnittsform (72, 72′) aufweist. With the sabot (60) according to the invention should by far Reduction of the dead load component the bending stiffness taking into account possible inexpensive series production be increased. This is achieved with the invention that the total cross section (50) of the sabot (60) at least in partial areas (36, 24) of its length kung a substantially polygonal cross-sectional shape (72, 72 ') has.

Hierdurch wird eine bisher unerreichte kostengünstige span­ abhebende Bearbeitung mittels z. B. einfacher Walzenfräser ermöglicht. This will make an unprecedented inexpensive chip lifting processing by means of z. B. simple milling cutter enables.
