Abstract: | Some characteristics of interior explosions within a cabin structure with a venting hole are investigated. It may simulate a warhead explosion inside a cabin following its penetration through the cabin wall. The study includes both experimental and theoretical analyses of the problem. The experimental investigation comprises of two types of explosives at the center of the cabin. The pressure distributions at different locations on the cabin wall are obtained. The effect of internal shock reflection is analyzed by using the method of images (MOI). It is found that the geometric symmetries can cause the multiple reflected shocks to converge with strength comparable to the initial free shock. |
