Description

Structure for multi-azimuth launching steel balls Technical Field The invention relates to the technical field of firearms, in particular to a structure for multi-azimuth steel ball emission. Background With the continuous evolution of modern war forms, unmanned aerial vehicles are increasingly widely applied to the battlefield, and by virtue of flexible maneuverability and strong combat effectiveness, unmanned aerial vehicles become an important force for changing future war rules. Particularly when an individual combat unit faces a threat, the powerful destructive power exhibited by the low-cost unmanned aerial vehicle poses a serious challenge to the traditional defense system. The light unmanned aerial vehicle is characterized by small volume and light weight, and can realize effective damage through the kinetic energy of a firearm, but is limited by the single-head bullet design used by traditional firearms such as an automatic rifle, a machine gun and the like, and when facing to the small-sized targets of the unmanned aerial vehicle which move rapidly, effective hit is difficult to realize, so that the light unmanned aerial vehicle becomes a key problem for restricting the improvement of the protection capability of an individual combat unit. In recent years, the increasing severity of unmanned aerial vehicle threats has prompted the counter technology to continually innovate. Among them, the shotgun exhibits certain advantages in the field of countering unmanned aerial vehicles due to its unique multi-shot design. The large coverage area is formed by shooting a plurality of shots at a time, so that the interception probability of the unmanned aerial vehicle is improved to a certain extent by the shotgun. However, existing shotgun technology still faces significant technical bottlenecks. During shot gun firing, the projectiles inevitably collide in the limited barrel space and these collisions are not concentric, resulting in significant shifts in the trajectory of the projectile. This phenomenon directly leads to a significant increase in the range of the shot spread over a longer distance, severely affecting the interception effect of the long-distance shot. Particularly, when the unmanned aerial vehicle approaches at a high speed, enough reaction time is often lacked, and the effectiveness of the existing countermeasures is further restricted. The existence of the technical bottleneck is a key problem to be solved in the field of unmanned aerial vehicle reaction at present.
