The space-time structure of fast jets flowing out from 
the cumulative groove of the detonating charge of a brisant explosive 
has been investigated. The velosity field of the jet and the flow 
of detonation products have been determined. We have revealed a change 
in the structure of the front end of the jet followed by an increase 
in its luminescence intensity and a decrease in the efflux velocity 
upon introduction into the cumulative groove of mixtures of metals 
and graphite. The sizes of the jet inhomogeneities reflecting the 
spatial scale of zones of selective change in its thermodynamic parameters 
have been estimated.
