Description

The invention relates to a sabot projectile for shooting from a weapon inserted tube.

DE 80 09 469 U1 describes that for exercise purposes in a large caliber Gun barrel an insert tube is to be used, from which smaller caliber, so cheaper Can fire ammunition.

DE 31 53 378 A1 describes a sub-caliber floor, the rear of which is tapered towards the back. This serves to reduce the air resistance of the floor in the Flight. A sabot is not shown.

A sabot projectile is described in DE 31 31 540 A1. This is ver low.

From DE-OS 15 78 104 another sub-caliber floor is known, which in his rear and cylindrical area is surrounded by a sabot, which is common sam is conical with the floor in the rear area. The taper of the hawker fighecks, however, is used only during the ejection from the gun barrel Purpose, a radial clamping in the conical rear area for swirl transmission from To create a sabot on the floor.

It has been observed that when shooting sabot projectiles from the above The insertion of the projectile is subject to wide variations. This can be traced back to the design of the sabot.  

The object of the invention is to provide a sabot projectile of the type mentioned hit, with the sabot the hit behavior of the projectile as little as possible impaired.

According to the invention, the above task in a sabot projectile is the one mentioned at the beginning ten Art solved in that the sabot rear side an aerodynamic cone shape has, which tapers towards the rear, that the projectile and sabot are of the same caliber and that the sabot is placed on the tailgate. With this design of the The sabot rear end has shown an improved hit behavior of the projectile.

The improved hit behavior can be attributed to the following:

The insertion tube is usually shorter than the gun barrel before its muzzle. Then leaves the sabot the plug-in tube, then the propellant gases overtake the sabot. The propellant gases flow unevenly past the sabot and grip thus asymmetrical or with turbulence on the sabot. This can lead to an ab steering the projectile and disturbances when separating the sabot from the projectile to lead. The aerodynamic cone shape of the sabot rear ensures that propellant gas overtaking the sabot in terms of flow technology at the sabot gel is passed by. The sabot does not distract the projectile and that too The separation behavior of the floor and sabot is hardly disturbed.

Advantageous embodiments of the invention result from the following description of embodiments. The drawing shows:

Fig. 1 shows a sabot projectile in the gun barrel after leaving the inserted pipe,

Fig. 2 to Fig. 5 different designs of the sabot of the projectile in longitudinal section.

An insertion tube ( 2 ) is inserted into a weapon barrel ( 1 ). The insertion tube ( 2 ) ends in the weapon barrel ( 1 ) before its mouth ( 3 ).

A sabot projectile has a storey ( 4 ) and a sabot ( 5 ). The sabot ( 5 ) is provided with a guide band ( 6 ) and adapted to the caliber of the insertion tube ( 2 ).

A conical body ( 7 ) is attached to the rear of the sabot ( 5 ). A screw bolt ( 8 ), which is screwed into an internal thread ( 9 ) of the sabot ( 5 ), can be provided on the body ( 7 ) concentrically to the longitudinal axis (L).

The largest outer circumference of the body ( 7 ) is aligned with the outer circumference of the sabot ( 5 ). The body ( 7 ) tapers backwards.

In the embodiment according to FIG. 2, the conical shape of the body (7) is conical. In the exemplary embodiment according to FIG. 3, the conical shape is convexly curved in a rotationally symmetrical manner with respect to the longitudinal axis (L). In the exemplary embodiment according to FIG. 4, the conical shape is concavely curved in a rotationally symmetrical manner with respect to the longitudinal axis (L). In the embodiment of FIG. 5, the conical shape is ogival.

The conical shape of the body ( 7 ) ensures that propellant gases (T) (see FIG. 1), which overtake the sabot ( 5 ) after leaving the insertion tube ( 2 ) before leaving the weapon tube ( 1 ), are aerodynamically favorable The sabot ( 5 ) flows so that they do not attack the sabot ( 5 ) asymmetrically to the longitudinal axis (L). This prevents the projectile ( 4 ) from being deflected. It is also avoided that the separation of the sabot ( 5 ) from the projectile ( 4 ) is disturbed.

Overall, this is the hit behavior of the floor improved or its spread in the target area reduced.
