Abstract: A subcaliber projectile assembly includes a subcaliber projectile; a supporting member engaging the circumferential surface of the projectile; a guide band supported on the supporting member; and a propelling cage supported on the circumferential surface rearwardly of the guide band. The propelling cage is formed of a plurality of segments mounted in a circular array and each segment is a stamped sheet metal component. Each segment has a bottom portion shaped as a circular cylinder section having opposite longitudinal edges and an underside being in engagement with the circumferential surface of the projectile. Each segment further has two longitudinal ribs connected to the bottom portion along the longitudinal edges and rising radially from the bottom portion. Each segment also has a transverse wall portion extending transversely to the bottom portion and the ribs and interconnecting the ribs with one another at a front-side longitudinal end of the segment.

Abstract: A subcaliber projectile intended for arrow stabilization has its guide assembly set so that the projectile spins around its longitudinal axis and is constructed so that it is unbalanced with respect to its longitudinal axis such that the spinning reaches a critical number of revolutions at a given time during the trajectory of the projectile and the resulting resonance causes destruction of the projectile.
