A projectile, particularly a kinetic energy projectile, whose nose cone is cooled due to the provision of an ablation layer and a thermal insulation layer (8, 9) on the exterior of the metal hood (4) of the projectile nose cone, and due to a highly thermally conductive medium in the spaces (5, 6) between the hood (4) and the payload (3) particularly a penetrator, of the projectile.

Projectile with cooled nose cone

A subcaliber kinetic energy projectile (1) including a penetrator (2) and a segmented sabot (3) which is provided with a front support (4) and with a second support (5) that is disposed at an axial distance behind the first support, with the second support (5) including a rotationally symmetrical air pocket (6) that faces the first support (4) and the first support (4) is provided with air passage openings (43, 44, 45).In the sabot, the relationship of L/D.gtoreq.1.2 exists between the length L of the penetrator tip (8) ahead of the first support (4) and the caliber D. The relationship x.gtoreq.0.45 * .iota. further applies between the distances x and .iota., with x being the distance between the trailing edge (10) of the sabot and the base surface (11) of the air pocket (6) in the second support (5) and .iota. being the distance between the trailing edge (10) of the sabot (3) and the leading edge (12) of the sabot at the surface of the penetrator (2). Finally, the first support (4) is composed of at least three laterally extending web-like components (40-42) whose shape and dimensions are such that they form and have the effect of three separate air pockets.

Subcaliber kinetic energy projectile

A sabot-projectile arrangement adapted for being ejected from a gun barrel for the purpose of combatting actively and passively reacting armor. The arrangement comprises first and second projectiles, each having a different coefficient of air resistance (c.sub.w). A discarding sabot is comprised of segments which define a receptacle for accommodating the first and second projectiles with their longitudinal axes flush behind one another in order to follow one another in a spaced relationship on a common trajectory when the sabot-projectile arrangement is fired from a gun. Form locking means defines a form locking connection between the receptacle and each of the projectiles. The form locking connection existing between the leading first projectile disposed in the receptacle and the segments of the sabot are released earlier than when the segments are separated from the second projectile after the sabot-projectile arrangement leaves the gun barrel. Delay means cause the second projectile to be delayed with respect to the first projectile when the segments are separated for creating a desired distance between the projectiles within narrow distancing limits within which there exists axial aerodynamic coupling between the projectiles. An actuatable device is provided for varying the c.sub.w coefficient of at least one of the projectiles during flight so that the aerodynamic coupling between the projectiles is maintained within the distancing limits.
