Harlan, J. G.; Rice, J. K.; Rogers, J. W.

Previous experiments using flying-plate devices for measuring the shock sensitivity of explosives showed that with vacuum conditions in the barrel of the device the detonation initiation threshold was 5 to 10% lower in terms of flyer-plate velocity and impact pressure than with air in the barrel. Therefore, a study was undertaken to measure the effects of air and other gases in these devices. The procedures and equipment are described. It was determined that the primary effect of gases in these devices is to change the initiation sensitivity through compression of the acceptor prior to impact of the flying plate. (LCL)
