Dynamics of heterogeneous liner with prolonged plasma production

The experimental and theoretical substantiations of the plasma formation delay in heterogeneous liners, when the liner substance is divided into two phases: the hot plasma and the liner cold shell, are presented. The basic mechanisms, determining the plasma formation rate, are considered and the simplest evaluations of this rate are presented. It is established that the electrical current by the delayed plasma formation flows through the whole cross section of the resulting plasma shell, the thickness whereof is comparable with the liner radius. Such plasma shells are characterized by noticeable elasticity, which leads to their higher stability by compression. The conditions for achieving the regime of the shell highly compact compression by maintaining its relative stability are developed on the basis of the simplified numerical modeling of the plasma shell compression with the delayed plasma formation process
