IGNITION OF LIQUID AND SOLID NITROCOMPOUNDS AT FAST COMPRESSION OF GAS INTRUSIONS
SINOPSIS
Initiation of explosion of liquid and solid explosives by rapid compression of gas intrusions has been the subject of extensive study during at least half of century. However only limited quantitative both theoretical and phenomenological description of the process till now is reached. This work is devoted to elaboration and application of two experimental procedures of the energetic materials initiation by means of the gas cavities compression. One of them named method U-shaped tube was used to generate data which revealed the role of air inclusions in causing ignitions during the rapid compression of a liquid in the broad range of conditions of its production or transportation. Another procedure consists of employment of fallhammer impact machine equipped with the impact device containing a layer of explosive on the bottom of the hole filled by air to investigate sensitivity of solid energetic materials, and to simulate possible conditions of in-bore premature explosions. Critical pressure of initiation is determined for many liquid explosives, preeminently nitrocompounds, in U-shaped tube. Dependence of critical pressure on the hole depth is estimated in fallhammer apparatus. The approximate theoretical relations are developed to describe the experimental facts.
