It can be shown  that for the suggested regime of Jet formation in the first approximation x , r0 x = (1 − cos(α + β )) /((2 + cos(α ) − cos(α + β ))sin(α ), Vmax ~ ctg(α ) 1 + 2C f where α - is a semiangle of the cone, β - is an angle between the plate and the symmetry axis, Cf - a coefficient of friction at the PJ propagation in a dense medium. Fig. 4. Plasma forced jet formation in a conical target: 1 – pushed plate, 2 – plasma jet It has been shown the realization of the forced Jet formation principle allows to increase both the speed and the pulse of the formed plasma jet essentially.
The possibility of estimating shock-wave parameters for an explosion near the surface using known relationships for underground explosions has been discussed several times. The question of defining parameters for pulse application to some point of the surface of a semispace remains quite complex. As has been noted previously , cavity growth in electrical explosion on the surface of water proceeds according to a law close to the law of self similar motion at constant energy. It seems it was pioneer work because this fact allow to introduce the energy transferred to the ground and estimate its value (perhaps somewhat arbitrarily) by comparing the mechanical action parameters of contact and slightly submerged charges.
