Abstract
The overpressure and impulse of the compression phase behind perforated partitions (PPs) located across a conical shock tube (CST) during the propagation of a spherical shock wave in it are experimentally determined. In the experiments, partitions with a different permeability are used. The intensity of the shock wave incident on the partition is varied. The obtained degree of attenuation of the overpressure and impulse of the compression phase of the shock wave increases with a decrease in the permeability of the partition and an increase in the intensity of the wave, remaining practically constant along the length of the CST.
