Abstract

A propulsion mechanism for a subcaliber projectile, wherein the propulsion mechanism possesses a close-fitted zone in common with the projectile for subjecting a gas pressure-receiving surface to a load caused by the propellent gases; for the utilization in a recessed surface, of an incident flow of air subsequent to exiting from a weapon barrel; and a tensioning device for the assumption of tensile stresses, with the device being connected with a central carrier component adjoining the projectile body.

Claims

1. Propulsion mechanism for a subcaliber projectile, comprising a common close-fitted zone with said projectile;

a gas pressure-receiving surface being subjected to propellent gases;

tensioning means for the assumption of tensile stresses, said tensioning means being connection with a central carrier component adjacent said projectile, said projectile propulsion mechanism further including membrane surfaces responsive to pressure such that mechanical forces which are encountered in said propulsion mechanism are converted into only tensile stresses and compressive stresses, said propulsion mechanism having ridge elements uniformly distributed about the circumferential direction thereof and commencing from the close-fitted zone of the carrier component each possessing an increasing wall thickness in the radially outward direction and being connected with a common glide element determining the outer diameter of the propulsion mechanism, said gas-pressure-receiving surface being formed by indented surfaces arranged intermediate adjacent ridge elements, said tensioning means being anchored between the carrier component and the glide element and being arranged in the interior of the propulsion mechanism extending over the indented surfaces.

2. A propulsion mechanism as claimed in claim 1, wherein the carrier component possesses a greater extent in an axial direction than the glide element, and the glide element is offset in an axial direction relative to the carrier component away from said indented surfaces.

3. A propulsion mechanism as claimed in claim 1, wherein the propulsion mechanism is constituted from at least two segment bodies.

4. A propulsion mechanism as claimed in claim 1, wherein said tension means in said propulsion mechanism comprises a plurality of whisker-like elements each consisting of an Al/Si oxide material.
