Spiral acceleration-type electromagnetic gun system and obtaining method thereof

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 supercon
