Abstract

To reduce the mass of a sabot having a pull and a push function, it is proposed that the sabot comprise mutually separate sabot parts, wherein at least one sabot part is configured such that it performs the pull function and at least one sabot part is configured such that it performs the push function. The sabot parts are nested. This can be implemented in the form of cylindrical nesting or in the form of tangential nesting. In the case of the cylindrical nesting, the outer sabot part encloses the inner sabot part along an interface. In the case of the tangential nesting, the sabot parts are divided into sabot subsegments. The latter are nested in alternating fashion in the tangential direction such that a pull-sabot subsegment and a push-sabot subsegment are nested in alternating fashion in the circumferential direction. To provide sufficient sealing, the sabot subsegments overlap one another.

First claim

What is claimed is:

1. A sabot comprising:
mutually separate sabot parts including at least a first sabot part having a surface upon which propellant gases act and at least a second sabot part having a surface upon which the propellant gases act, each of the first and second sabot parts being positively connected to a projectile to accelerate the projectile when acted upon by the propellant gases,
wherein the first sabot part and the second sabot part are positioned on the projectile such that the propellant gases first act on the surface of the first sabot part, such that the first sabot part performs a pull function by causing tension to accelerate the projectile and the second sabot part performs a push function by causing pressure to accelerate the projectile.

2. The sabot according to claim 1 , wherein the sabot parts are nested.

3. The sabot according to claim 2 , wherein the sabot parts are nested by a cylindrical interface.

4. The sabot according to claim 1 , wherein the first sabot part having the pull function forms an inner sabot and the second sabot part having the push function forms an outer sabot.

5. The sabot according to claim 1 , wherein the sabot parts have mutually separated surfaces on which propellant gases can act.

6. The sabot according to claim 5 , wherein the surfaces merge with each other to form a common surface of the sabot.

7. The sabot according to claim 1 , wherein each of the sabot parts include sabot subsegments.

8. The sabot according to claim 7 , wherein a push-sabot subsegment and a pull-sabot subsegment are nested in alternating fashion in the tangential direction.

9. The sabot according to claim 7 , wherein, three of the sabot subsegments have a pull function and three of the sabot subsegments have a push function.

10. The sabot according to claim 7 , wherein each of the sabot subsegments has a respective surface on which propellant gases act.

11. The sabot according to claim 1 , wherein there is no positive connection between the sabot parts.

12. The sabot according to claim 1 , wherein with respect to a radial direction of the sabot, there is a radial gap between the first sabot part and the second sabot part, such that there is no positive connection between the first sabot part and the second sabot part.

13. The sabot according to claim 1 , wherein a majority of the first sabot part is positioned on the projectile closer to a rear end of the projectile and a majority of the second sabot part is positioned on the projectile closer to a forward end of the projectile.

14. The sabot according to claim 1 , wherein a portion of the surface of the first sabot part is curved and the surface of the second sabot part is linear.

15. A projectile comprising:
a sabot,
the sabot comprising:
mutually separate sabot parts including at least a first sabot part having a surface upon which propellant gases act and at least a second sabot part having a surface upon which the propellant gases act, each of the first and second sabot parts being positively connected to the projectile to accelerate the projectile when acted upon by the propellant gases,
wherein the first sabot part and the second sabot part are positioned on the projectile such that the propellant gases first act on the surface of the first sabot part, such that the first sabot part performs a pull function by causing tension to accelerate the projectile and the second sabot part performs a push function by causing pressure to accelerate the projectile.

16. Ammunition comprising the projectile according to claim 15 .

17. The projectile according to claim 15 , wherein with respect to a radial direction of the sabot, there is a radial gap between the first sabot part and the second sabot part, such that there is no positive connection between the first sabot part and the second sabot part.

18. The projectile according to claim 15 , wherein a majority of the first sabot part is positioned on the projectile closer to a rear end of the projectile and a majority of the second sabot part is positioned on the projectile closer to a forward end of the projectile.

19. The projectile according to claim 15 , wherein a portion of the surface of the first sabot part is curved and the surface of the second sabot part is linear.
