In order to further understand the detonation characteristics of annular booster pellets, the energy convergence effect from the detonation wave on the central axis was investigated by using the segmentation and lower end surface output. The result shows that in the whole explosion process, the power exportation capability (N) of the converging energy flow into the central axis increases, then decreases, and then increases and finally decreases. When the collision incidence angle of the detonation waves (or shock waves) reaches a critical value (φ_cr), Mach reflection occurs at the position on the central axis from the upper end face, as expressed by the formula h_c = Lg·tanφ_cr at time t. The pressure at the collision point rises abruptly to the maximum pressure with a maximum of the power capacity. The segmentation and lower end face output opens up a new test method for the optimal design of the special-shaped booster explosive.
