Definitions
- the invention relates to a sabot projectile with a large length / diameter ratio with a sabot consisting of segments, which has an air pocket on the front.
- a projectile of the aforementioned type is known from DE-PS 17 03 507.
- the sabot has the air pocket in the front support and a rear edge in the vicinity of the second support, around which the segments are detached from the balancing projectile.
- the swinging of the projectile can severely impair both its accuracy and its penetration.
- the latter relates primarily to the effect against new types of targets, which require both particularly long projectiles with a ratio of length to diameter that is significantly higher than 10, as well as the greatest possible freedom of oscillation.
- Studies on the behavior of projectile-sabot arrangements have shown that unstable flow conditions can occur in the area around the front part of the projectile, which impair the uniform segment-wise detachment of the sabot.
- the invention has for its object to provide an improved sabot projectile, the improvement mainly relates to the detachment behavior of the sabot.
- the floor 10 is only shown in parts in all figures. 1 to 3 preferably show a tip area of the projectile 10, while FIGS. 4 and 5 show the front area of the sabot, which is also shown only in parts.
- a sabot projectile of the type described acts only because of its kinetic energy and contains no explosive charge.
- the peripheral region 16 in the vicinity of the tip 18 has an annular projection 34.
- the tip body 15 has a cone tip 22 with a rear step 24 which establishes a jump in diameter.
- the tip body 15 is provided on the front with a hemisphere 26, the rear base surface of which has a step 28 for achieving a jump in diameter.
- the tip body 15 consists of z. B. nine circular cylinder bodies 36, 40, 44, 48, 52, 56, 60, 64 and 68.
- the circular cylinder body 36 forms the tip 18 with a comparatively small diameter and is delimited on the rear by a step 38 which delimits the subsequent circular cylinder body 40 on the front on a comparatively larger diameter.
- Further steps 42, 46, 50, 54, 58, 62, 66 and 70 form jumps in diameter between the respectively larger circular cylinder bodies, the step 70 being bounded on the circumference by the base edge 14 between the circular cylinder rod 11 and the front region 12.
- the structures shown all lead to at least one contour discontinuity in the front area 12.
- This defines an otherwise oscillating, pulsating or vibrating axis in the axial direction between a flow area in which supersonic speed prevails and a recirculation area.
- the pressure fluctuations which have a detrimental effect on the detachment behavior of the sabot segments from the projectile are avoided.
- an angle that a head wave of the front area 12 generates becomes larger or smaller. At a larger angle, a flatter head wave profile forms. In this way, a profile can be formed in which the head shaft no longer hits the front edge of the sabot. This also prevents interference with the detachment process.
- a substantially 76 caliber area 76 of the sabot 72 surrounds the air pocket 74.
- the area 76 extends from a front edge 78 to a rear edge 80.
- the edge 80 delimits a rear surface 82 which leads into a tapered central area 84.
- a front surface 86, 88 forming the air pocket 74 is delimited on the front by a circular edge 90.
- a track 92, which connects the circular edge 90 to the edge 78, is curved such that its center of curvature (s) lies on the side of the circular edge 90 facing away from the front region 12, not shown.
- the retraction of the circular edge 90 ensures that it is not hit by the above-mentioned head wave, interfering with the detachment process.
- the invention can be applied jointly both in the front area of the floor or in the design of the sabot as well as in both areas. This advantageously allows a good adaptation to the respective requirements and circumstances.
- the segments can also detach from the floor, starting from the rear or essentially parallel to the longitudinal axis of the floor.
