Flyer is the key part of the non-primary detonator, which determines whether the detonator could explode. In the present paper, the flyer plate model driven by explosive is applied to the flyer calculation of the excitation device. The velocity range of the detonation velocity and the flyer is determined by experiments, and compared with the numerical results.. Comparing the results, the conclusion is made that the unstable detonation happened in the excitation power, and Gurney energy is only 10%~30% of explosion heat, and some factors which could affect the flyer velocity are also given.
