Effects of Current Guides Destruction at Ultra‐fast Acceleration of Macrobodies

The paper is devoted to discussion of current guides destruction effects in different accelerators: thermal‐electric and electro‐magnetic rail accelerator at macrobodies acceleration value of 108–109 m/s2.Experimental results with thermal‐electric accelerators powering from megajoule capacitor battery and helical magneto‐cumulative generator MCG‐100 at currents up to 3.5 MA are analyzed.The process of rails destruction at railgun at pressure magnetic field excess over the limit of metal fluidity is presented. Methods of efficiency coefficient increase of capacitive storage energy transmission to kinetic energy of accelerating body are discussed.
