Abstract

The factors influencing delay time of detonation wave of superfine insensitive HMX in limited corner channel were analyzed. The dimension analysis method was adopted to induce the theory formula, and the delay time was tested by valid experiments in the limited corner of 0.8 mm x 0.8 mm and 0.6 mm × 0.6 mm channel. Results show that the delay time of detonation wave is longer in the channel d = 0.6 mm than d = 0.8 mm with similar corner, and the propagation of detonation wave will be failure when α = 2π/3. Based on the theory formula and the testing results, the semi-experimental equation is given by Least Square Method, and the undetermined coefficients k and m are 365.8 and 4.75.
