摘要： A limited range, supersonic, sub-caliber projectile having a main body and a resistance-stabilizing tail section. This tail section has at least two bores through which air passes during flight of the projectile. The axes of the bores may be parallel or inclined relative to the longitudinal axis of the main body of the projectile.

摘要： A practice projectile has a cylindrical casing having front and rear portions; a bottom section attached to the rear portion of the cylindrical casing; a frontal nose section including at least two subcomponents which have front and rear portions. The subcomponents can assume a closed position in which the projectile has an external configuration identical to that of a live projectile having the same caliber and an open position in which the subcomponents are in a spread-apart state at a given opening angle. The rear portion of the subcomponents is pivotally connected to the front portion of the cylindrical casing. There is further provided a device for holding the subcomponents together in the closed position prior to firing the projectile. The holding device is arranged to be overcome by centrifugal forces derived from a projectile spin subsequent to firing, to thereafter allow the subcomponents to assume the open position.

摘要： A subcaliber arrow projectile includes a projectile body which has a rearwardly widening, conical projectile tip having a forward point and a rearward base, whose caliber corresponds to the projectile caliber. The projectile body further has a rearwardly widening, resistance-stabilizing conical rear part immediately adjoining the base of the projectile tip. The rear part has an enlarged caliber which is greater than the projectile caliber.

摘要： A sabot for a subcaliber projectile, preferably an arrow projectile, having an essentially cylindrical guide gage (8) of a lightweight material and a tail-side drive element (14) detachably connected thereto for tail-side support of the projectile body (1). The guide cage (8) has a radially inwardly-extending support wall (12) for supporting a projectile body (1) disposed therein in its forward to central region, and the drive element is a propelling disk (14) that is received by a circumferential or annular groove (13) in the tail region of the guide cage (8), which is segmented in the axial direction of the projectile body (1). As a result, a further reduction in weight can be accomplished with simpler fragmenting of the sabot that practically does not impair the projectile at all.
