Abstract: Jetting in cylindrical cumulation is an elusive process. The paper investigates cumulative jetting dur-ing the compression of cylindrical shells by means of a hydrodynamic model and numerical simulation. A method for improving jetting in cylindrical cumulation and normalizing the temperature in the jet formation zone – using a small diameter tube inside the main cladding made of refractory ni-obium – has been proposed and substantiated. The critical factor in the jet formation zone is out-lined. Thus, suggestions were made to improve cumulative jetting in cylindrical cumulation.

Keywords: cylindrical cumulation, cylindrical shell compression, explosive throwing, hydrodynamic theory of cumulation, high-temperature phenomena.
