Light anti-high-overload integrated bullet holder for electromagnetic rail gun

Abstract

The invention provides a light anti-high overload integrated bullet holder for an electromagnetic rail gun. The light anti-high overload integrated bullet holder comprises a bullet holder main body, aclamp type bullet belt, a flying body, a protection holder and a ring type bullet belt. The bullet holder main body comprises a protection pipe internally provided with a containing cavity, one end of the protection pipe is provided with a bottom holder for sealing the containing cavity, the clamp type bullet belt is composed of two C-shaped clamping blocks with the same structure, the two clamping blocks are symmetrically installed on the protection pipe through buckles, the flying body is composed of a conical air cap, a cylindrical bullet body and a tail wing with fins, the protection holder is installed in the containing cavity and fixes the tail wing, and the ring type bullet belt is installed on the outer surface of the protection holder. The contact parts of the bullet holder mainbody and the flying body have no structural design and are only in transition fit, by means of the design, the machining difficulty of the bullet holder can be lowered, the mass center of the flying body is made to move forwards, flying stability is improved, meanwhile, friction resistance on the surface of the flying body is also reduced, and speed keeping performance of the flying body is improved.

Description

technical field [0001] The invention relates to the military field, in particular to a lightweight anti-high overload integrated bullet holder for an electromagnetic rail gun. Background technique [0002] Electromagnetic railgun, as a new concept kinetic energy weapon with great application prospects, has been highly concerned by the world. In recent years, the energy scale of the international advanced level has exceeded 100 MJ, and the technical state has entered the demonstration prototype stage; Electromagnetic energy replaces the gas pressure of traditional gunpowder combustion, and the projectile is accelerated by electromagnetic force to form a super-high-speed projectile launch. It has the characteristics of high initial velocity, long range, high power, high precision, and strong destroying ability. [0003] However, most of the projectiles configured in the electromagnetic railgun system are sub-caliber tail-stabilized armor-piercing projectiles. When launching, t...

Problems solved by technology

In addition, the high initial velocity of the projectile in the electromagnetic railgun means that the short-term high acceleration means high overload, and the maximum overload exceeds 100,000 g. The traditional connection method between the projectile core and the projectile holder is prone to shear failure. Once the projectile moves in the bore If damage occurs during the process, the launch efficiency and service life of the electromagnetic railgun will be significantly reduced
