Sabot

Abstract

The invention relates to a sabot (1) which comprises multiple sabot segments (1.1, 1.2, 1.3). The sabot (1) or the sabot segments (1.1, 1.2, 1.3) are characterized by having a structural design at an end (10) opposite the shooting direction such that a low degree of flexural rigidity is achieved at said end (10). A sabot (1) with three sabot segments (1.1, 1.2, 1.3) is preferred. The sabot (1) or the sabot segments (1.1, 1.2, 1.3) have a rear part (3) as a push part and a front part (4) as a pull part. In order to optimize the shape and weight, the front part (4) and the rear part (3) have recesses (5, 6) in the sabot (1) or in the sabot segments (1.1, 1.2, 1.3). Braces (8, 9) are integrated between the recesses (5, 6), or the recesses (5, 6) are introduced between braces (8, 9).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention is to be explained in more detail with reference to an embodiment with a drawing.

(2) The drawing shows:

(3) FIG. 1 shows a sabot according to the invention in a perspective view in the shooting direction from behind,

(4) FIG. 2 shows a sectional illustration of the sabot of FIG. 1.

DETAILED DESCRIPTION

(5) In FIG. 1, a sabot 1 is shown for a sub-caliber projectile (not shown in greater detail). The sabot 1 is shown obliquely from the rear when viewed in the shooting direction. The sabot 1 has at least two sabot segments 1.1, 1.2. The sabot 1 preferably has three sabot segments 1.1, 1.2, 1.3. Plastic, aluminum or the like can be used as material. Such materials are customary and known.

(6) The sabot 1 or the sabot segments 1.1, 1.2, 1.3 are characterized in that they are designed as a push-pull sabot or push-pull sabot segments. A part 3 of the sabot segments 1.1, 1.2, 1.3 (front part) located in front of a pressure flange 2 accelerates the sub-caliber projectile (not shown in greater detail) by means of pressure, and a part 4 (rear part) located behind of the pressure flange 2 accelerates it by means of traction. In addition, a propellant pressure acts on the pull part 4, while the push part 3 is free of external loads.

(7) The front part 3 (push part) and the rear part 4 (pull part) are in turn preferably optimized in terms of shape and weight. For this purpose, the rear part 4 and the front part 3 have recesses 5, 6 in the sabot segments 1.1, 1.2, 1.3. Braces 8, 9 remaining between these recesses serve to ensure sufficient rigidity of the sabot 1 or the sabot segments 1.1, 1.2, 1.3.

(8) The sabot 1 or the sabot segments 1.1, 1.2, 1.3 have pockets 7 integrated in the rear part 3.

(9) According to the invention, the sabot 1 or the sabot segments 1.1, 1.2, 1.3 have a structural design at an end 10 opposite the shooting direction such as to be very thin, as some kind of tiny tail. In case of an ammunition in the caliber of for example 105 mm, this cylinder shape (or tiny tail) can be created within the last 20 mm to 30 mm of the sabot 1 or the sabot segments 1.1, 1.2, 1.3. The wall thickness can be approximately 3.5 mm to 4.5 mm. As a result of this design, this special end 10 has a low degree of flexural rigidity. Due to this flexibility, impulsive forces occurring between the sabot 1 or the sabot segments 1.1, 1.2, 1.3 and the projectile or penetrator (not shown in greater detail) can be reduced. The homogenization of the detachment forces of all sabot segments 1.1, 1.2, 1.3 also reduces the initial oscillation of the projectile. A so-called detachment edge 11 is introduced between the sabot segments 1.1, 1.2, 1.3.

(10) A receptacle of the projectile (not shown in greater detail) is denoted by 12. Projectile and sabot 1 are connected to one another via an indicated threaded connection.

(11) FIG. 2 shows the sabot 1 or a sabot segment 1.1, 1.2, 1.3 in a sectional view.

(12) The mode of operation is as follows:

(13) As a result of the propellant gases, the sabot 1 or the sabot segments 1.1, 1.2, 1.3 together with the projectile are driven through a weapon barrel (not shown in greater detail). The weapon barrel is responsible for guiding the projectile in the weapon barrel. The sabot 1 and the projectile separate after passing the muzzle, and the sabot segments 1.1, 1.2, 1.3 separate after passing the muzzle. The necessary force is generated by the dynamic pressure in the pockets 7 of the sabot 1 or the sabot segments 1.1, 1.2, 1.3 when these pockets 7 are exposed to ambient air. The sabot 1 or the sabot segments 1.1, 1.2, 1.3 roll over the projectile during detachment. Due to the low flexural strength of the ends 10 of the sabot 1 or of the sabot segments 1.1, 1.2, 1.3, the detachment forces of the sabot 1, i.e., of all sabot segments 1.1, 1.2, 1.3, are homogenized.
