Small-caliber projectile with deformable and flexible empennage and implementation method thereof

Abstract

The invention discloses a small-caliber projectile with a deformable flexible empennage and an implementation method thereof. According to the small-caliber projectile, a brush-type empennage is installed on the tail portion of a projectile body of the small-caliber projectile, and materials with light weight and good flexibility are adopted; in the storage and transportation process, hairs are restrained by a launcher and curled in an installation hole and abutted against the inner wall of the launcher, if vibration occurs, friction is generated between the hairs and the inner wall of the launcher, and the relative position between the projectile body and the launcher is stabilized to improve stability of the projectile body in the transportation process; when the projectile is fired andlaunched, the projectile body is launched from the launcher, the hairs are released from the restraint of the launcher, and transient high temperature occurs in the process in which the projectile body leaves the launcher, so that hardness of the hairs is enhanced, each cluster of the hairs is uprightly unfolded from the installation hole to form a fixed brush-type empennage in the air, and the projectile body can stably fly; stable installation and fixing of a fuse are achieved through a circular electrode to prevent interference of complex electromagnetic signals and improve sealing performance in the launcher.

Description

technical field [0001] The invention relates to throwing small-caliber projectiles, in particular to a small-caliber projectile with a deformable flexible tail and a realization method thereof. Background technique [0002] Among the various types of missiles currently developed by our country, the types of empennage mainly include: with empennage and without empennage. Among them, the traditional tailless bomb has a conventional aerodynamic layout, light weight, and small size, which makes it have the advantages of high aerodynamic efficiency, large lift-to-drag ratio, and relatively low power consumption, and is widely used in small-caliber bombs. However, in a large overload environment, the missile body is greatly disturbed by the surrounding environment and cannot adapt to the complex physical environment, thus reducing the use efficiency; since then, the tail-type missile structure has developed rapidly. During the process, the rapid opening of the empennage improved ...

AI Technical Summary

Problems solved by technology

However, for small-caliber projectiles, by adding the tail device, the processing difficulty of small-caliber projectiles increases, resulting in high processing costs and lower yields. Moreover, processing the tail fins increases the quality of the small-caliber projectile body

In addition, in the traditional launch system, the missile fuze function is generally set by wireless connection, which is easily interfered by external signals, such as: complex electromagnetic environment, etc.

It is easy to cause false triggering or failure of the bomb

In addition, the airtightness between the launch tube and the body of the traditional ammunition is poor
