Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] A projectile bottom structure with the function of reducing the impact of falling. A buffer structure is added to the bottom surface of the existing projectile bottom. The buffer structure is plastically deformed when the bottom of the projectile falls downward, so that it is destroyed first.
[0015] The projectile bottom includes a rotating projectile bottom, a projectile bottom equipped with a projectile bottom fuze or an empennage projectile bottom.
[0016] Such as figure 1 As shown, a bottom structure with the function of reducing the impact of falling adopts a buffer structure 13 . The buffer structure 13 is a homogeneous or heterogeneous disc glued to the bottom of the fuze 12, and the fuze 12 is arranged at the bottom of the missile body 11.
[0017] Such as figure 2 As shown, a bullet bottom structure with the function of reducing the imp...

The invention discloses a projectile bottom structure with a function of reducing falling impact. The projectile bottom structure with the function of reducing falling impact is characterized in thata buffer structure is additionally arranged on the bottom surface of an existing projectile bottom, the buffer structure is plastically deformed when the projectile bottom falls down and is destroyedat first, certain falling impact energy is absorbed, so that the aim of reducing the impact on the projectile, particularly a fuse on the projectile, is achieved, which has great significance in improving the safety of a fuse recoil safety mechanism, the buffer structure is a circular piece, a plurality of protruding structures or a thin-wall circular ring integrated with the projectile body, thebuffer structure is relatively small in size and cannot obviously affect an original structure. According to the projectile bottom structure, the function of reducing the falling impact of the projectile can be realized, the falling safety of the projectile and the fuse thereof is improved, the cost can not be obviously increased, and the performances of ammunition launching, flying, fragment damage and the like can not be obviously influenced.
Description
technical field [0001] The invention belongs to ammunition technology, and in particular relates to a bottom structure of a bullet with the function of reducing the impact of falling. Background technique [0002] It is inevitable that the projectile will accidentally drop during duty handling. If the impact of the drop is too large, in addition to possibly damaging or destroying the optoelectronic components and explosive components on board the bomb and thus reducing the reliability of the fuze, it may also cause the fuze to be accidentally disarmed or make it difficult to guarantee the safety of the fuze. Instances of serious accidents caused by the accidental fall of the fuze during service processing, disarming insurance or even catching fire still occur from time to time. In fact, the fall safety of the projectile, especially the fuze, is very important both at home and abroad. [0003] GJB 4403A-2018 "Conventional Ammunition Packaging Type Test Procedures" was promu...
