Abstract

An impact projectile which comprises at least two impact bodies centered with respect to one another and disposed one axially behind the other with means for separating the two bodies axially upon approach to the target. The separation can be effected by thermal means controlled by a proximity switch and/or by flight duration. The projectile is especially designed for penetrating armored vehicles having multi-layer armored walls.

Claims

1. An impact projectile for firing from a smooth-bore barrel-type weapon such as a tank for targeting on an armored wall, comprising:

a plurality of axially aligned, axially spaced, elongated annular impact bodies including a nose body at a leading end of said projectile, a tail body at a trailing end of said projectile, and a plurality of intermediate bodies between said nose body and said tail body whereby said bodies are adapted to successively engage said wall, all of said bodies being formed with axial bores;

a rod extending through said bores and anchored to said tail body at a trailing end of said body;

respective dished-disk springs received between each body and the next body along said rod and forming elastic spreading means for biasing said bodies apart;

means at said nose body releasably engaging a leading end of said rod for retaining said bodies against relative axial movement and axial movement relative to said body and simultaneously maintaining each of said dished-disk springs under compression until release of said means;

a fin-stabilizing structure on said tail body; and

a drive cage surrounding at least some of said bodies whereby said projectile forms a subcaliber projectile for said barrel-type weapon.

2. The impact projectile defined in claim 1 wherein said means is a material of a low melting point fixed to said leading end of said body and fusible to release said bodies for relative movement of said bodies and movement of said bodies relative to said rod by said springs.

3. The impact projectile defined in claim 1 wherein said means includes a proximity detector provided on said nose body and connected to a member adapted to be energized by said detector at said leading end of said body for releasing said bodies for relative displacement and for relative displacement of said bodies with respect to said rod by said springs.
