A composition of 98/2 weight percent PETN/polybutadiene elastomer was formulated, sprayed on bridgewires and electrically initiated, to determine the,feasibility of such deposition of explosives bonded to test surfaces. Test firing resulted in a detonation reaction which could mean that explosive compositions sprayed on test surfaces may be an important tool in testing structural integrity, e.g., as presently in the Vulnerability Testing Program. A semi-automatic apparatus for spraying explosive formulations on chemically etched electric circuits, support membranes and/or test vehicle surfaces has been designed, and improved application processes are being developed
