Abstract

Abstract

The Mach reflection occurs when two high-detonation-velocity detonating cords are arranged symmetrically on both sides of the cartridge. After the detonation the explosive's detonation waves converge and collide along the line of symmetry, multiplying the detonation pressure and forming a Munroe effect region with high pressure and high energy density when the collision angle reaches a certain value. In this paper, explosive-determination of power and brisance tests were conducted based on the theory of detonation wave collision and reflection. The results from the test of the explosive-determination of power show that the detonation wave collision can improve the efficiency of the explosive energy utilization, and those from the test of the brisance show that the symmetrical initiation of the detonation can change its distribution in a particular direction. The geometrical relationship of the experimental results with the incidence angle of the detonation wave shows that, when the initiating explosive velocity is above 1.15 times that of the main charge, the detonation wave collision will produce a certain degree of Munroe effect.
