The invention discloses a novel armour piercing hollow
projectile. The novel armour piercing hollow
projectile comprises a
projectile body, a ballistic cap, a bottom bolt and a bearing band, the projectile body is a hollow circular tube, the projectile body is composed of a cone section warhead at the front end and a cylindrical section projectile main body positioned behind the cone section warhead, the hollow
radius of the projectile body gradually increases from the warhead to the projectile
tail, the ballistic cap is arranged at the front part of the cone section warhead, the ballistic
capis in a tapered streamline shape, the bottom bolt is fixedly connected to the
tail part of the projectile body, and the bearing band is long-strip-shaped and is fixed on the outer side of the projectile body. According to the novel armour piercing hollow projectile, hollow design enables the projectile body to be lighter than a
solid projectile body with the same length, the larger
muzzle velocity is obtained, the shooting distance is longer, crushed concrete enters a circular tube at the inner part of the projectile body under the action of pressure, the bottom bolt is extruded, so that thepressure of the head of a penetration body and the severe action area of a target material is reduced, and the resistance is further reduced. Due to the fact that particle materials are easily subjected to the dilatancy effect under the crushing state, the circular tube is designed with a certain taper, so that the outlet end close to the
tail part is larger, and the crushed body can easily pass the outlet end.
