In order to improve the present aviation ejection lifesaving system and enhance success possibility of safe escape, the application of Miniature Detonating Cord (MDC) on the aviation ejection-escape-system is proposed. The explosion cutting process of plexiglass (PMMA) plate and Canopy by MDC are simulated employing nonlinear dynamic explicit program LS-DYNA3D. The variation of cutting depth with charge quantities is obtained, which agrees well with the experimental result. Simulation result shows that the geometry of PMMA has slight influence on the cutting effect. This study may provide the powerful foundation for the design of the aviation ejection lifesaving system.
