Description
Technical Field

Background
The small-caliber cannonball mainly hits short-range and low-altitude targets within 3000 meters, and has irreplaceable tactical low position in the aspects of attack through attack, near-end air defense and short-range combat. The small-caliber cannonball fuse is used as the core of the small-caliber cannonball and has the characteristics of multiple types, wide application and large using amount. With the fact that the operation environments of the fuzes of the small-caliber shells are more complicated and diversified, the large impact angle of the large back surface and the pit and depression when the rotating speed of the fuzes is not reduced to the self-explosion threshold value is increased in the actual combat training. Statistics shows that the firing rate of the existing small-caliber shell fuze is low due to large attack angle target collision, and the unexplosive shell has the outstanding problems of hidden danger in reliability and safety. Although the small-caliber cannonball has high requirements on the firing reliability of the fuze under the condition of terminal air defense, in the existing firing test of the fuze of the small-caliber cannonball under the condition of large firing angles, target plates with different inclination angles are shot for firing, the phenomenon of 'jump' is easy to occur when the target plates are hit under the large firing angles, and the target plate target is reduced due to the inclination of the target plates. According to statistics, under the same landing speed, the simulated 70-degree landing angle miss rate is 21%, and the 80-degree landing angle miss rate is greatly increased to 70%. The phenomenon of 'bouncing' and high miss ratio cause the existing large angle firing test to have high cost and limited simulated angle.
