Critical energy for shock initiation of fuze train explosives

Description: Results of shock initiation experiments conducted for tetryl and A-5 are presented, along with some data on the shock initiation of other explosives. The experiments were conducted using a gun system. An equation which has been useful in correlating these shock data is given. Some applications of the critical energy concept (represented by the above equation), to explosive train designs for NASA space systems are included. The concept's usefulness to DOD ordnance agencies now replacing tetryl in fuze trains with A-5 is also indicated. (auth)
