The Pressure Characteristics of Nonel Tube in Its Detonation Growth Process

摘要

The pressure characteristics of nonel tube in its detonation growth process were studied by means of dynamic data testing and analyzing system. The experiment shows that there is a 30 ～ 50cm length of detonation growth period, the ignition pressure and ignition impulse of nonel tube increase with the increasing of propagation distance of detonation. After 50cm or more length of detonation growth, the detonation comes to be stable. The results of this determination can be reference to the application of nonel tube when it is used as initiation element in blasting networks.
