Abstract
The formation of a fast gas jet from not too long, plane, U-shaped charges is studied by radiography. It is shown that a shock-compressed region is fo rmed in the air cavity as a result of collision of explosion products. Afte r detonation of the charge, a jet flows from this region with a velocity ex ceeding the detonation velocity. The jet exhibits a cumulative effect, whic h is maximal for a square air cavity.
