Abstract: To investigate the characteristics of damage and effective damage area from the synergistic detonation of combat sections and engine detonation, a overpressure calculation model based on the interaction of different intensity shock waves was established. Utilizing finite element simulation software, numerical simulations of the synergistic detonation of engines with different mass propellants in combat sections were conducted to obtain shock wave parameters at different positions during the synergistic detonation. The damage enhancement effect and effective damage area characteristics under different working conditions were analyzed, and the effective damage contour lines for synergistic detonation were mapped based on the damage criteria of shock waves to the target. The results indicate that the synergistic detonation of combat sections and engines has a significant damage enhancement compared to the detonation of combat sections alone. The enhancement effect is related to the detonation method, the remaining propellant mass, and the spatial position. When the ratio distance < 1.25, simultaneous detonation has a greater enhancement, and when > 1.75, shock detonation has a larger enhancement, and the enhancement effect increases with the remaining propellant mass and distance. The effective damage area of the synergistic detonation consists of three parts: the combat section axis damage area, the engine axis damage area, and the radial Mach wave damage area. The radial Mach wave damage area has a greater enhancement in shock quantity than the enhancement of overpressure. The findings of this study provide a reference for the design of synergistic detonation of combat sections and engines and damage-propulsion integration.
