Underground Ammunition Storage. Blast Propagation in the Tunnel System. Report IV A. Connected Chamber Storage. Variable Chamber Volume and Variable Angle between Branch and Main Passageway

Abstract

Model tests have been performed to determine the blast wave propagation in the tunnel system of underground ammunition storage sites with connected storage chambers. A total of 18 different configurations were tested with variable chamber volumes (300 - 15200 cc), angles between the branch- and main passage-way (35 - 90 degrees), and ratios between the cross sections of the branch- and main passage-way (0,125 - 0,5). The models were in linear scales 1:40 to 1:100 of typical full scale installations. By analyzing the data, it was possible to obtain relatively simple scaling relationships which contain all of the most important geometrical parameters. The model data are compared with one large scale test and fair agreement is found.
