Novel armour piercing hollow projectile

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of ammunition, and in particular relates to a novel armor-piercing hollow bullet. Background technique [0002] Hollow projectiles are also called tubular projectiles because the flying part is a thin-walled round tube with a hollow center, which belongs to a new type of supersonic ammunition. At present, foreign research on hollow bullets is mainly based on application development research and feasibility experiments. Domestically, hollow bullets mainly carry out aerodynamic characteristics and some experimental verifications, while research on hollow bullet design methods is less. For the design of hollow bullets, the traditional method is still the main method. The outer surface of the bullet is a cylinder with a large central through hole inside. The front and rear parts of the central hole are internally tapered and the middle is cylindrical. Therefore, the designed hollow projectile cannot satisfy the...

AI Technical Summary

Problems solved by technology

Therefore, the designed hollow projectile cannot meet the optimal overall performance, let alone have good aerodynamic and ballistic characteristics.

Moreover, the current design process of hollow bullets does not make full use of new materials, and the size of some parts is too large, resulting in a further increase in the negative mass of the entire hollow bullet
