A spiral acceleration electromagnetic gun system and its realization method

Abstract

The invention discloses a spiral acceleration-type electromagnetic gun system and an obtaining method of the spiral acceleration-type electromagnetic gun system. The spiral acceleration-type electromagnetic gun system comprises a spiral-type superconductive electromagnetic boosting subsystem, a high-temperature superconductive magnetic suspension subsystem and a superconductive magnetic confinement subsystem. An electromagnetic gun boosting process is carried out in a spiral acceleration mode through the spiral-type superconductive electromagnetic boosting subsystem and the requirement for impulse power of a boosting system is lowered; a superconductive magnetic suspension technology is adopted in the high-temperature superconductive magnetic suspension subsystem for eliminating mechanical friction, so that ablation of a projectile body and a gun barrel is avoided; high centrifugal force generated because the spiral radius is small in the acceleration process of the projectile body is overcome by the superconductive magnetic confinement subsystem according to a superconductive magnetic confinement technology; heat-dissipation-free design of the gun barrel is achieved by the electromagnetic gun system according to the electrical-resistance-free characteristic of a superconductive material, and therefore the high-firing-speed continuous firing capacity is achieved. According to the spiral acceleration-type electromagnetic gun system, the spiral gun barrel and the spiral acceleration mode of the projectile body are adopted, so that high outlet speed is easy to achieve; no mechanical friction and ablation influence on the gun barrel exists in the whole firing process and the gun barrel can be used for a long time; active control over a boosting coil is not needed and the problem that a traditional halved joint electromagnetic gun is difficult to control is solved; forced cooling and heat-dissipating waiting do not needed to be conducted on the gun barrel in the process of continuous firing and the continuous firing capacity of the spiral acceleration-type electromagnetic gun system is far higher than that of the traditional electromagnetic gun.

Description

technical field [0001] The invention belongs to electromagnetic launching technology, relates to an electromagnetic gun, in particular to a structure design and realization method of a helical acceleration type electromagnetic gun. Background technique [0002] At present, conventional weapon systems use chemical energy as the main energy source, and the initial velocity of the projectile launched by it will be limited by many factors such as charge amount, propellant composition, launcher material and gas sound velocity, and its theoretical limit is only 2-3km / s or so. At the same time, the controllability and compatibility of chemical fuel weapons are poor. Once the design of the weapon system is completed, it is difficult to adjust the parameters according to different projectiles and application scenarios, which cannot meet the combat needs of modern warfare under all-weather complex conditions.
