Abstract
An empirical dependence is presented of the maximum effective explosive cylinder length on a number of basic factors in the projection of plates by opposing detonation waves. This dependence was obtained on the basis of experimental investigations. The obtained length may be twice the length of the limiting effective length of an explosive cylinder which is initiated only in the direction from the launched plate. In addition, a range of explosive cylinder lengths is established in which, compared to the initiation in the direction only from the plate, the opposing initiation provides a gain in plate energy by a factor of ∼1.3.
