Abstract
The electroexplosive and electrothermal mechanisms and the principles of conduction and induction electrodynamics are used simultaneously to convert electromagnetic energy to the kinetic energy of projectiles. This approach is implemented on the basis of the well–known configuration of a coaxial pinch accelerator. It is established that there is an “active” lengths of the barrel on which the system ensures launching with nearly constant acceleration. For a barrel length of 340 mm and a barrel diameter of 17 mm, bodies with a mass of 1—12 g are accelerated to velocities of 3.4—1.45 km/sec with an energy conversion efficiency of 25—29% at a capacitive storage voltage of 1.75 kV and a discharge current of up to 150 kA. Bodies with a mass of 40—80 g (barrel diameter 25 mm are accelerated to velocities of 1.3—1.0 km/sec with an efficiency of 28—20% at a voltage of 3.5 kV and a current of up to 220 kA.
