Experimental Investigation of Propagation Properties of Blast Waves In Air and in Semi-rigid Polyurethane Foam

CHEN Wang-hua, FENG Wei, PENG Jin-hua (Nanjing University of Science and Technology, Nanjing 210094, China)  
The reflected overpressure distribution of blast wave of No.8 detonator with pap er shell was measured in semi-rigid polyurethane foam (SRPUF), and the incident overpressure distribution of the detonator in air was also tested in this paper . By the symposium of ideal-gas-state-equation, the reflected overpressures i n air were calculated. The contrast and the analysis on the two reflected overpr essure distribution were carried out. The propagation properties of the blast wa ves in the two media were discussed qualitatively, and the gap and cushioning pr operty of SRPUF material was analyzed as well.
